Glenn Hauser logs+, September 26-27, 2021

** CUBA [and non]. 11760 et al., UT Monday Sept 27 at 0135, I make a point of reconfirming RHC DX program `En Contacto` at its third and last scheduled airing: yes, it has just started. For convenience I`m tuning via Bonaire SDR. 11760 is not very good, fading down, so at 0140 try 9710 but it has CCI and ACI, i.e. CRI Spanish 9710 via Cashgar, Turquistán Oriental, tierra de genocidio por los imperialistas chino-comunistas, en contra de musulmanes, and 9705 probably jammer vs RFA Tibetan via Tajikistan. 9535 is better, but also with CCI which would be CRI English via via Kashgar --- some comrades!! By 0145 I`ve switched again to 5040 which is loud & clear. Something`s always wrong at RHC.

As for content: main topic is the term ``Mayday`` and how it came about; the locutora massacres the original French, ``m`aider`` pronouncing as if were Spanish. In this brief program it`s broken up into segments; says that it`s not supposed to be as serious as SOS, like need-some-help-here, but English usage has led to it being just as urgent, as a dire emergency. Strangely, she never gets into how it relates to the big Commie holiday!

Then about several ham DX-peditions with calls and QSL info; and special events, notably A60EXPO from Dubai. I have the impression she is reading a script without really understanding it. 0143 seems to give times for this show, but not clear as I am retuning. 0144 about solar activity. 0147 references ARRL webpage URLs --- do they not realize those are from Yanqui Imperialists?? 0148 more about ``Mayday``.

Another topic is ``qué es el desacoplo de la polarización`` = decoupling of polarization. This only merits a few words at the very end, and I don`t get it. 0150 closing credits including guión as usual by CO7GW; locución by Ariadna(?) García. NO mention of Arnaldo Coro Antich --- how is Arnie doing now? 0151 into Doctor show (Glenn Hauser, OK, WOR)

** MEXICO [non]. Not a log yet, rather advance notice of something I meant to mention on WOR 2105 but missed:

``Special Broadcast:
México le canta a las Américas (Mexico Sings To the Americas)
Date/Time: Tuesday, September 28th, 0300-0400 UTC**
**Monday, September 27 2200-2300 Mexico City Time / CDT WRMI 5800 kHz

In honor of the 200th anniversary of the end of the Mexican War of Independence, a special hour of Mexican music hosted by Luís Alejandro Vallebueno with guests Gabriela Ortiz and “Uncle Bill” Tilford will air on WRMI with support from Grupo DX México. It will be in Spanish and directed towards Central and South America, but the back end of the transmission should be listenable in most of North America and parts of Western Europe and Africa. The music will be a combination of world-famous artists and others probably not known outside of Mexico. There will also be some items regarding history, customs and shortwave in Mexico including special appearances by a veteran of Radio México Internacional (aka XERMX in its days on shortwave) and a long-time member of Grupo DX México ---------------------- William "Bill" Tilford, Owner/Producer, Tilford Productions, LLC``

This is also the big night for other UB programs, on WBCQ 7489.9v: 2300-2330 Monday, first half of `Melting Pot`; 0000-0100 UT Tuesday, `From the Isle of Music` = Cuba; interspersed with lots of gab, interviews with the musicians (via Glenn Hauser, WOR)

** OKLAHOMA. RF 29, the KTUZ ``Shawnee`` full-power transmitter with three different Spanish networx, each displaying a farflung virtual channel -- Telemundo as 30, Univision as 36, and Estrella as 48, now with three more sub-channels, shopping networx in English, first noticed in step-tuning Sept 27 at 0036 UT: 30-2 QVC, 30-3 HSN, 30-4 QVC2. I see these are already listed at I check the RF channel for each to be sure they are really out of RF-29. They have probably moved from some other LP transmitter for OKC market (Glenn Hauser, Enid, WOR)

** SAUDI ARABIA. 17895.069, Sept 27 at 1414, Qur`an from SRI/SBA, S5-S8 and the SSOB beyond a few JBA carriers, no sign of any other Sa`udis circa 17660, 17615 or 17570, supposedly on air now (Glenn Hauser, OK, WOR)

** U S A. 245-MCW kHz, Sept 27 at 0613 UT, ND beacon FS, which is 400 watts from Sioux FallS SD. Not much else heard with high noise level. I was tuned to 243-USB (and also forgot to mention with my MA 326 kHz log yesterday that I was tuned to 325-USB) (Glenn Hauser, OK, WOR)

** U S A [and non]. WORLD OF RADIO 2105 monitoring: confirmed Sunday September 26 from 2000.7 on IRRS via AM Italia 918 kHz, S9+35 into Noale SDR. Preceded by music, IRRS ID.

Also confirmed Sun Sept 26 after 2230 on WRMIs, 5950 S9+30 and 9955 S9+15 into east TN SDR.

Also confirmed UT Mon Sept 27 at 0030 on WRMIs: 7730 VG direct; via east TN SDR: 9455 only S9 way offbeam; 9395 VG S9+20, but with ``RTTY warble`` QRM on plus side only, clear with LSB tuning. Much like the QRM to IRRS 7290. Measured about 9396.1; by 0045, WRMI has faded way down and the RTTY rules. Never noticed such QRM on 9395 direct to OK.

Also confirmed UT Mon Sept 27 at 0130 on WRN North America webcast.

Also confirmed from just before 0300 UT Mon Sept 27 on Area 51 via WBCQ, 6160 minus 53v Hz = 6159.947v, S9+5 into Maryland SDR with some ACI from 6165 Cuba even in LSB tuning. Previous show ended in time for full WBCQ singing ID at 0259.5, but after WOR billboard started, interrupted for another quick WBCQ `legal` ID. At 0325 direct check here, S8-S9 with ACI. Next, not until Wednesday:

1030 UT Wednesday WRMI 5850 to NW
2100 UT Wednesday WRMI 7780 to NE
2100 UT Wednesday WBCQ 7490v to WSW
0030 UT Thursday WRMI 9395 to NNW, 9455 to WNW

** U S A. 9330, Sept 27 at 1445, no signal from WBCQ-6 SuperStition of World`s Last Chance; why is it still so unreliable, more breakdowns? However, there is a JBA carrier on 9333, anomaly I have noticed before, *only* when 9330 is off, making me wonder if it`s also from BCQ, maybe an off-frequency exciter? After 1500 checking remote further east, no sign of either (Glenn Hauser, OK, WOR)

UNIDENTIFIED. Trans-oceanic JBA MW carrier search, Sept 27 at 0604-0610: 531, 585, 603, 621(2), 639(2), 657, 684, 693(2), 747(2), 774(2), 837, 846, 855(2), 936, 999(2), 1089, 1098, 1125(2), 1134(2), 1152, 1215, 1305(2), 1413(2), 1503(2) --- after Algeria, probably lots of Canary/Spain, some UK (Glenn Hauser, OK, WOR)

UNIDENTIFIED. 3819-USB, Sept 17 at 0618, hamchew about drivers and antennas, both stations, yes, on USB, not LSB, and not AM either. I guess LSB on 40 & 80m is only a convention, easily refused (Glenn Hauser, OK, WOR)

Highlights of Solar and Geomagnetic Activity
20 - 26 September 2021

Solar activity was at very low to moderate levels. Region 2871 (S27,
L=357, class/area=Dao/310 on 21 Sep) produced the largest flare of
the period, an M2/1n flare at 23/0444 UTC. Associated with the flare
was a Type II radio sweep (966 km/s) followed by a Type IV radio
sweep. A subsequent CME signature was observed in SOHO/LASCO C2
coronagraph imagery. Analysis and modeling of the event suggested
most of the ejecta was away from the Sun-Earth line but a glancing
blow from the periphery of the CME may be possible on 27 Sep. An
additional M1/1n flare was produced by the same region at 23/1528
UTC. A subsequent CME signature associated with the event was also
analyzed with a similar potential for the periphery of the ejecta to
influence Earth around 27 Sep.

Other activity included a Type II radio sweep (739 km/s) associated
with an eruption around Region 2875 (S32, L=053, class/area Bxo/010
on 24 Sep). The associated CME signature was narrow and directed
away from the Sun-Earth line. Most numbered active regions were in
decay and they transited through the W hemisphere with most decaying
to plage by the end of the period. The remaining numbered regions in
the E hemisphere were relatively simple and quiet.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels throughout the reporting period.

Geomagnetic field activity ranged from quiet to active levels.
Active levels were observed on 22 Sep in response to a SSBC followed
by influence from positive polarity CH HSS. Unsettled conditions
were observed on 21 Sep, and 23-25 Sep due to coronal hole activity.
The remainder of the reporting period was quiet.

Forecast of Solar and Geomagnetic Activity
27 September - 23 October 2021

Solar activity is expected to range from very low to low levels. Low
levels are likely on 27-29 Sep and very low levels are likely for
the remainder of the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach moderate to high levels. High levels are likely on
29 Sep - 02 Oct, 05-08 Oct and 20-21 Oct due primarily to influence
from multiple, recurrent CH HSSs. Normal to moderate levels are
expected for the remainder of the outlook period.

Geomagnetic field activity is expected to range from quiet to G2
(Moderate) geomagnetic storm conditions. G1-G2 (Minor-Moderate)
conditions are likely on 27 Sep in response to combined effects of
an anticipated positive polarity CH HSS and possible glancing blow
from a CME that left the Sun on 23 Sep. Active conditions associated
with coronal hole activity are likely on 28-29 Sep, 05 Oct, 10 Oct
and 19 Oct. Unsettled conditions are likely on 04 Oct, 18 Oct and
20-21 Oct. The remainder of the outlook period is expected to be at
quiet levels.

Expo 2020 Dubai Opening Ceremony on WRMI Sept 30

WRMI will broadcast the Opening Ceremony of the World's Fair, Expo 2020 Dubai, on Thursday, September 30 at 1600-1800 UTC on 9955 kHz and on our Internet stream at

At that time, Dubai is inviting the world to come together to celebrate the opening of the Expo 2020 World's Fair, which was originally scheduled to open at the same time last year, but was postponed for a year due to the coronavirus pandemic.

This spectacular event, hosted in Al Wasl Plaza on the Expo site, will feature an array of international, regional and local talent. Audiences will enjoy a masterful display of stunning music and performances, as some of the world's most creative minds come together in a dazzling, groundbreaking performance. Among the performers will be the world-famous opera singer Andrea Bocelli.

Drawing inspiration directly from Expo's theme of "Connecting Minds, Creating the Future," the Opening Ceremony will take listeners on a journey across its subthemes of Opportunity, Mobility and Sustainability, showcasing the deep-rooted values of the United Arab Emirates and the vision and purpose of Expo, while welcoming the event's 192 participating countries in spectacular fashion.

Brazil Report on SW Digital Broadcasts

The report on the successful trail of shortwave in DRM for domestic use in Brazil was recently published. The trial at the end of 2020 and beginning of 2021 was a joint effort between The Ministry of Science, Technology, Innovation and Communications in Brasilia, the University of Brasilia, EBC – the public broadcaster, the DRM Brazil Platform, and other commercial enterprises and interested parties. The aim was to get extensive coverage in DRM SW especially over the wide and sparsely populated of the Brazilian northern areas, the rich Amazonian region.The report gives a detailed report on the set up and results of the DRM trial and demo. It concludes that: "...the successful realization of Phase 1 of the project necessarily implies continuity, with the development and dissemination of national low-cost DRM receivers in Phase 2. One cannot lose the "savoir faire" or knowledge acquired so far and thus condemning isolated populations to ignorance due to lack of information. This opens up a new perspective for quality communication over long distances, integrating the most distant regions of Brazil."

Spaceshuttle 12265 kHz today

History of SSB

History of SSB
From: Scott Blixt
Date: Sat, 25 Sep 2021 21:08:31 UTC

AWA Video: SSB was Slow to Catch On as a Ham Radio Mode

Hams are often early adopters of new technology, such as FT8, but this was not the case with single sideband (SSB) amplitude modulation. First referenced in Major General George Squier's 1911 patent that had nothing to do with RF applications, SSB didn't really catch on as a popular ham radio phone mode until the 1960s.

Antique Wireless Association (AWA) museum curator Ed Gable, K2MP, recounted "The History of Single Sideband" as part of the inaugural "AWA Shares" program, presented on August 19. Gable described Squier as an "early idea man" in the history of SSB at a time when hams had hardly adopted AM inany form.

As Gable explained, John Renshaw Carson built on Squier's patents to define the principles of SSB radio transmission theory, using a balanced modulator and filters. AT&T went all in with SSB, basing its first long-haul telephone system on the technology. Its SSB voice service to Europe, which kicked off in 1923, lasted for more than 3 decades. A receiving site in Scotland took advantage of Beverage antennas put in place for the ARRL transatlantic tests.

Gable credited Robert M. Moore, W6DEI, with introducing SSB to the ham radio community, through an article in R9 Magazine in the early 1930s. The technology remained more of a curiosity, however, in part because of the Great Depression, cost, and technical difficulty. Besides, hams of that era saw no real advantage to narrowband modes, since bands were not that crowded.

The mood began to change after World War II, though. In 1948, Oswald Villard, W6QIT, engineered the airing of SSB signals via Stanford University's W6YX, re-introducing the mode to a burgeoning and more technically savvy post-war ham community that included a lot of veterans. A 1950 GE Ham News article by Don Norgaard, W2KUJ, described plans for a 5 W, three-tube SSB transmitter he dubbed "The SSB Jr."

The Central Electronics Model 20A.

Expanding on this, Central Electronics' Wes Schum, W9DYV, built the first SSB exciter, the 10A, in 1952, and it became the company's first product, spawning a series of successor products that included a VFO based on a modified BC-458 military surplus transmitter, an "SSB slicer" for receiving, and even a linear. SSB equipment was neither inexpensive nor accessible, however.

"Cheap and Easy S.S.B." by Anthony Vitale, W2EWL, which appeared in QST in 1956, spoke to hams' attitudes, helping to advance the adoption of SSB among radio amateurs. Byron Goodman, W1DX, addressed receiver improvements with his QST article, "The Product Detector."

The Collins KWM-1 is considered the first "true" transceiver, sharing receive and transmit circuitry.

In the same decade, General Curtis LeMay, K3JUY/K4RFA, promoted the advantages of SSB to the military, heralding a phase-out of AM as the dominant voice technology. Many hams were not convinced of SSB's advantages, deriding the signals as sounding like Donald Duck. Adoption didn't really take off until the Collins KWM-1 came along in 1957. It was the first SSB transceiver to share receiver and transmitter circuitry. Heathkit, Viking, and B&W produced SSB adapters for use with current AM gear.

Other manufacturers including National and Swan came along to further boost adoption of the mode, and it wasn't that many years before SSB eclipsed AM as the predominant voice mode on the HF bands.

** CHINA. CNR1 WOOB jammer search, Sept 26 at 1356: JBA carriers on 12820, 13020, 13130, 13190. Also at 1421, 9155 at S5-S9, 9255 at S5-S8 in Chinese. All of these fit against Sound of Hope, in Aoki & EiBi except unlisted 13190 (Glenn Hauser, OK, WOR)

** CUBA. 5025, Sept 26 at 0603, R. Rebelde is S9+20/30 and splashing out +/- 13 kHz almost to 5040, where RHC is already off tonight: opposite situation to last night, returning the favor. Something`s always wrong at RadioCuba (Glenn Hauser, OK, WOR)

** CUBA. 13700 and much weaker 13740 but still spurless, Sunday Sept 26 at 1347, RHC with COVID-19 medical info, instead of `En Contacto` DX program. `En Cía del Doctor` had been scheduled at 1350-1400 after E.C. at 1335-1350. I`m been remiss in monitoring for E.C., whether it still exist without Arnie (Glenn Hauser, OK, WOR)

** GERMANY. 5905, Sept 26 at 0608, JBA YL in German: that would be Deutscher Wetterdienst, scheduled also on 6180 where there is an even weaker JBA carrier, both 0600-0630 daily, 2x 10 kW at Pinneberg but based in Hamburg. It`s now the #1 SW station in Germany! ahead of DW on page 475, WRTH 2021. A ``National Radio`` station? Guess not. I made the mistake of hunting for it first in that sexion among 15 pages of detailed almost-all-FM listings (Glenn Hauser, OK, WOR)

** GUAM. 11965, Sept 26 at 1417, rock with heavy beat, then talk sorta Thai? S9-S7 with flutter. Aoki shows KSDA this semihour only daily in Ash language. WRTH shows this under, where else, Thailand, page 498, with Chin(Asho) to S Asia at 1400-1430 then on 11870 in B-20 season. EiBi calls it C-A for MYA[nmar] ``Chin-Asho: Myanmar-Ayeyarwady, Rakhine (30,000) [csh]`` not to be confused with CA which is Cantonese (Glenn Hauser, OK, WOR)  

** NEW ZEALAND [and non]. 11725, Sept 26 at 0558, RNZI is S9+10/20, the SSOB and almost the OSOB, some JBA carriers on 11815, 12000, Brasil and Cuba. I expect to hear Bell Bird and QSY announcement to 7245, but 11725 keeps going with 0600 pips and RNZ news. Sked on website still shows 0558/0559 changeover. After 0600, nothing on 7245; nor 7255 Nigeria, nor 7265 France which is M-F only. So vacant! NZ perhaps confused as DST has just started. Domestic program relays will now be one real UT hour earlier, not necessarily SW block frequency scheduling too (Glenn Hauser, OK, WOR)

** U S A. 326-MCW kHz, Sept 26 at 0623 UT, ND beacon MA, which is 400 watts from Midland, Texas. I remain wondering why I hear so few NDBs from Baja Oclajoma as opposed to many more to the north as far as Canada. My E-W longwire should be equally unfavorable to both, altho Midland is WSW rather than S (Glenn Hauser, OC, WOR)

A cuore aperto: Johnson Messenger 2-23 (1976)

Per il nostro appuntamento a cuore aperto, ho pensato di mostrare un apparecchio che si potrebbe definire storico per la storia delle comunicazioni a breve raggio. Si tratta di un ricetrasmettitore per la banda 27 Mhz, il famoso quanto raro JOHNSON 2 - 23, un apparecchio 23 canali, interamente valvolare e non importato in Italia.


Funzionante a 110 Volts, questo apparecchio denota da subito una buona costruzione, solida e ben eseguita; la presenza del suo microfono originale, di sicura costruzione TURNER, dà a tutto il complesso un aspetto professionale e rigoroso. Impiegante 10 valvole, 11 diodi e 6 transistor, ha la media frequenza a 455 Khz ed il ricevitore è a singola conversione, come tutti gli apparecchi di questo tipo.


La presenza di 6 transistor, apparsi in questa versione, è dovuta all'utilizzo di un sintetizzatore di frequenza per ottenere i 23 canali utilizzando soltanto 14 quarzi. L'estensione è quella classica; da 26.965 a 27.255, con il canale 9 ancora cerchiato in rosso come canale di emergenza e la classica spaziatura tra il canale 22 ed il 23. L'aspetto molto essenziale lascia spazio ai soli controlli di volume e squelch, alla griglia dell'altoparlante ed allo strumento S meter che, come sempre, dà indicazione del segnale in ingresso e della potenza relativa in uscita.


L'emissione avviene in 6A3, ampiezza modulata ed il trasmettitore eroga tutti i suoi 4 watt dichiarati dalla Casa, grazie alla volenterosa quanto robusta valvola finale 7061, pilotata da una 8077. L'ingresso microfonico è ad alta impedenza. Il modulatore, che utilizza la stessa finale di bassa frequenza audio, una 12AB5, e funziona in classe AB1, fornisce una modulazione di alto livello ed è dotato sia di filtro audio (400/2500 Hz), che di clipper per evitare la sovramodulazione dello stadio stesso.


In ogni caso, garantisce una profondità di modulazione non inferiore al 30% e non superiore all'80%. La presenza di un sintetizzatore di frequenza solleva il costruttore dall'utilizzare quarzi tagliati sulla fondamentale e di usarne per quanti siano i canali di emissione, aumenta la stabilità ed abbatte i costi dei cristalli stessi. Il microfono originale impiega la classica capsula ceramica che, anche dopo più di 50 anni, fà ancora il suo lavoro in modo perfetto.


Sul retro troviamo la presa di antenna, il fusibile e la linea di alimentazione ed a questo proposito, anche se il costruttore asserisce che l'apparecchio possa funzionare tanto a 50 quanto a 60 Hz, alimentandolo a 115 Volts 50 Hz, si nota un minimo di ronzio residuo in altoparlante che scompare elevando la frequenza di rete a 60 Hz.


Il telaio è ben realizzato ed il montaggio curato e razionale, dal lato componenti si nota qualche riparazione e sostituzione componenti ma in sostanza, quasi tutto è originale ed è da notare il largo uso di ceramica per le bobine ed i compensatori. L'apparecchio appartiene all'amico Andrea IK5CI di Firenze, che me lo ha affidato per una riparazione, revisione e controlli. Alla prova, l'apparecchio si è dimostrato più che valido, facendosi ascoltare a circa 12 Km di distanza con buon segnale e modulazione di buon livello.


Parlare di un apparato per gli 11 metri potrebbe sembrare riduttivo o meno importante rispetto ad altri ma bisogna sempre tenere presente il fatto che questi apparecchi siano niente altro che dei piccoli ricetrasmettitori HF monobanda, canalizzati ma pur sempre apparecchi per le onde corte che hanno dato modo di comunicare anche a chi non ha patente o a chi non poteva prenderla ma si sono distinti anche in occasione di eventi catastrofici come terremoti e calamità naturali, dando modo di poter sapere notizie ancor prima dell'arrivo dei soccorsi. Di qui la mia idea di mostrarne almeno un paio.

Paolo Pierelli

Della Serie Radiotecnica in pillole: "Radio a Cristallo e Detector alla ZINCITE"

Nel secolo scorso, anni 20, erano molto in voga i ricevitori passivi funzionanti con Detector a Cristallo, apparecchietti semplici da costruire, a basso costo, di facile impiego e indipendenti da fonti di alimentazione, dato che la modesta energia per il loro funzionamento veniva captata tramite il sistema d'aereo, come allora si chiamava l'antenna, fatta alla bell'è meglio da un lungo filo di rame. In quel periodo furono numerosi gli esperimenti per trovare i cristalli migliori da impiegare come possibili Detector: la Galeria, il Carborundum, la Pirite e vari altri minerali ed anche metodi diversi, qui parliamo forse del cristallo meno conosciuto: la ZINCITE che é naturale ossido di zinco, minerale particolarmente resistente alle radiazioni e anche oggi in parte impiegato nei moderni Diodi LED.

Nel lontano 1922 in Massachusets U.S.A. nella cittadina di Newton, un giovane ricercatore dal nome Illya Glossop, trafficando nel suo laboratorio con diversi minerali per usarli come Detector, scopri che in determinate condizioni, se una piccolissima area di un cristallo di Zincite veniva polarizzata con basso voltaggio, accadeva che i1 cristallo messo sotto tensione andava in auto oscillazione, fatto strabiliante! Sulla base di questa fantastica esperienza disegnò un circuito di un semplice ricevitore che aveva come Detector un cristallo di Zincite che veniva polarizzato usando, per fare il contatto, un pezzetto dì filamento di carbone recuperato da una vecchia lampadina, invece del solito baffo di Gatto di acciaio. Una semplice polarizzazione di circa 10 Volt indotta nel Cristallo di Zincite era sufficiente per determinare una resistenza negativa e faceva partire l'auto oscillazione. Questa era la condizione principale che generava in un sol colpo rivelazione e amplificazione del segnale che poi giungeva amplificato alla cuffia. Questo ricevitore venne chiamato "Crystal - Dine', bel nome che vuol dire: "Eterodina a Cristallo'.

Nel libro "Radio Ricevitori a Cristallo" di G. Moronii - Edizioni il Rostro - nel corso dell'esaustiva carrellata di come funzionano questa tipologia di ricevitori e come costruirli, si parla anche del Detector a Zincite e si precisa che il "Segreto" per il suo funzionamento è trovare il punto più ottimale del cristallo per ottenere il giusto punto di auto oscillazione con 1a adeguata polarizzazione, perché occorre creare tra il punto di contatto e il Cristallo di Zincite una adeguata differenza di potenziale e regolando questa differenza di potenziale si ottiene che il contatto invece di avere resistenza, generi una risultante negativa che va a diminuire la resistenza del circuito di antenna con l'effetto che i segnali ricevuti appaiono amplificati rispetto ad altri tipi di rivelatore a cristallo, perché questo fenomeno fa si che l'antenna appaia come fosse cinque o sei volte più lunga del normale, captando cosi maggior segnale. Come detto il contano che porta alla polarizanione del cristallo di Zincite ha resistenza negativa, quindi aumentando tramite un reostato la differenza di potenziale applicata, l'intensità della corrente che circola non aumenta ma bensì diminuisce, creando l'effetto amplificativo e inoltre qualora malauguratamente l'operatore non riesca a trovare un punto sensibile per innescare l'oscillazione, la Zincite funziona sempre come un normale cristallo di Galena, pur non amplificando il segnale. Nel libro vi è il semplice schema costruttivo del ricevitore a Zincite e si consiglia al posto del baffo di gatto l'uso di un vecchio filamento di lampadina in carbone, sí suggerisce di pulire con alcool puro il cristallo e di guardare se con la polarizzazione di una pila da 9 Volts o poco più, si forma tra il filamento di carbone e il cristallo una piccola scintilla a stellina color verde brillante, ebbene quello è il punto più sensibile che é andato in auto oscillazione; allora si sente il fischio nelle cuffie e quindi regolando il potenziometro della polarizzazione pian piano si elimina il fischio e d'incanto si sente la voce o il suono che diviene ben amplificato. Con pochi componenti il gioco è fatto. Siamo andati indietro negli armi 20, un tuffo nel mondo della Radio del passato, allora ci si accontentava di tanta magia e molte soddisfazioni con poca spesa e tanta resa!

** U S A. 9950 & 9960, Sept 25 at 0606, TOMBS modulation is JBA on plus and minus 5 kHz spurs out of 9955 WRMI, unusually strong in the nightmiddle S9+30. First time I have detected such, but like the 4975 spur out of 4980, reconfirmed at 0623. Perhaps they are far enough `down` to be negligible if WRMI even be aware of them. When 9955 is so strong, I suspect it`s really on a more northerly antenna than the nominal 160 degrees attributed 24/7 to XMTR 3 (Glenn Hauser, OK, WOR)

** U S A. 5059 & 5111 approx., Sept 25 at 0620, traces of spur carriers which work out as 2nd-orders out of 5085 WTWW-2. I.e. twice the ~13 kHz offsets of the first-order ones circa 5072 & 5098. Just as I tune in, music stops but dead carrier stays on. Amazingly, no one else seems ever to report the painfully obvious closer ones, let alone their doubles. Something`s always weird at WTWW (Glenn Hauser, OK, WOR)

** U S A. 4840, Sept 25 at 0624, WWCR in dead air yet again at S9+60! instead of dead Stair, who continues haunting us on 3215, 5890, as well as dead Scott on 5935. A trifecta anyway (Glenn Hauser, OK, WOR)

High power transmitters at world’s highest radio station at Humbatingla in Kargil to be inaugurated today

Union Information and Broadcasting Minister Anurag Thakur will inaugurate high power transmitters at world’s highest radio station at Humbatingla in Kargil.

AIR correspondent reports, at an altitude of 13 thousand 300 feet from mean sea level, each 10kW High Power Transmitters of All India Radio FM radio station and Doordarshan will improve the transmission and the reach in the region especially in Kargil and Batalik sectors. With the inauguration of highest elevated transmitters, people in the mountainous region would get better quality services of AIR and DD. The new transmitters are part of Government’s efforts to improve information reach to the public, especially to the bordering villages in Ladakh.

In the meantime, responding to the appeals from several quarters including Member of Parliament Jamyang Tsering Namgyal and Ladakh Autonomous Hill Development Council, Leh CEC Tashi Gyaltson, I&B Minister Anurag Thakur announced to double the transmission of Ladakhi News and Programs on DD Kashir DTH platform from October. Similarly, Anurag Thakur also assured to improve All India Radio transmission services to reach every nook and corner of Ladakh region.

Voice of America launches Bambara language service

WASHINGTON — Recognizing Mali’s importance to security and governance on the African continent, the Voice of America launched a Bambara language broadcasting service on September 22, Mali’s national independence day.

“By establishing a separate Bambara service, VOA is investing new resources in its programming to the region,” said Acting VOA Director Yolanda López. “Our goal is to continue producing authoritative reporting for millions of Malians that provides even more content from a dedicated staff in this new service.”

VOA Bambara language broadcasts began in 2013 as part of French-to-Africa language service programming on shortwave, on 24/7 FM stations in Bamako, Gao, and Timbuktu, on digital platforms, and on regional affiliates. The new Bambara service programming will include a daily morning show, live streaming from Bamako, and greater multimedia content from Bambara-speaking communities in Burkina Faso and Ivory Coast.

The Voice of America delivered round-the-clock multimedia coverage of Mali’s August 2020 and May 2021 military coups, serving as one of the country’s primary sources of independent news, especially in its northern regions now largely controlled by Tuareg separatists and Islamist groups.

The daily Bambara news radio program “Mali Kura” covers events across the Sahel, the region of Africa separating the Sahara Desert to the north and tropical savannas to the south. VOA provides in-depth analysis and context on the current affairs show “Djamu Kan” and on the call-in show “An Ba Fo.” Bambara-speaking audiences get the latest entertainment news and major artists’ interviews on the weekly interactive youth show “Farafina Foly.” VOA Bambara’s expansion as part of this new language service includes a television health show and more on-demand videos for social media.

Propagation News – 26 September 2021

This week saw the Sun more active with up to five sunspot regions in place. Two of the regions are quite large, pushing the solar flux index up to 89 on Thursday with a sunspot number of 76. That should be enough to get the ionosphere up and running and we are also seeing early Autumnal HF propagation starting to take off.

Gary, G0FWX reports working Central America and the Caribbean on 10 metres, namely Venezuela, Puerto Rico and Surinam. Brazil has also been logged, but we are still awaiting widespread reports of North American stations to be logged on 28MHz.

Geomagnetic conditions have been variable with the Kp index hitting four on Wednesday, thanks to material from a coronal mass ejection. This sent the solar wind speed up to more than 400km per second and it was still above 300km/s on Thursday.

There has been solar flare activity recently and we can expect it to continue. This could mean sudden ionospheric disturbances and HF blackouts if the flare is strong enough and occurs during daylight hours. There could also be associated coronal mass ejections to contend with.

Next week NOAA predicts the solar flux index will remain in the mid 80s while the Kp index should eventually decline to two after reaching five this weekend. This is due to a coronal hole which is currently facing Earth. A high speed solar wind stream flowing from this zone should reach Earth later this week and contribute to a geomagnetic disturbance at higher latitudes.

VHF and up:

As predicted last week, we had a mix of weak Tropo and rain scatter modes, with an isolated report of the Cornish 10GHz beacon GB3MCB being copied for an hour by G4DBN in East Yorkshire at 460km overland.

This coming week the Tropo conditions will take a hit as low pressure becomes the dominant pattern for the coming week. This will take the form of active fronts crossing the country together with areas of showers, so at least there will be some rain scatter potential for the GHz bands.

At the moment, indications are that the return of any ridges, and hence Tropo, between the lows will be temporary and limited in scope, so best to think of other options like meteor scatter or aircraft scatter and possibly aurora to provide the unconventional modes this week.

There is one small meteor shower due to peak this week. The daytime Sextantids with a ZHR of five is due to peak on the 27th, but the timing of this peak is often uncertain. The maximum may occur even a day earlier than expected, so be alert and continue to check the early morning for the best random meteor scatter conditions.

EME path losses are at their highest this week with apogee today, Sunday, but with peak Moon declination coming up on Wednesday there is plenty of Moon visibility for Moonbounce enthusiasts. The Moon is at its zenith in the early morning. (

India - DD Turns 62

India’s public broadcaster Doordarshan turns 62 this month, celebrating a long journey that began as a modest experiment in 1959.

Gradually, it grew and paved the way for the emergence of a new era in the Indian television industry. During the initial years, there were makeshift studios and voice and visuals were beamed through a small transmitter.

The experiment turned into a service in 1965 when Doordarshan reached TV sets in living rooms in and around the country’s capital – Delhi. By 1972, Mumbai and Amritsar were added and then to seven other cities by 1975.

By the 90s, it had started reaching our hearts even in remote areas of the countries and people used to remain glued to their TV sets for their most-loved programmes.

It was Doordarshan that brought epics like Ramayan and Mahabharat on the silver screen for every Indian household. Its music show Chitrahaar and Rangoli won our hearts in the 80s and 90s. There were many other news and entertainment shows that made people aware of their country and the current developments around the world. It soon turned into a driver for the celebration of India’s diversity and its unity.

The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Last week, we reported a big increase in activity with the daily sunspot number reaching 124, but by the end of that week all sunspots had disappeared. The sun was blank for several days, but sunspots returned on September 19.

Average daily sunspot numbers this week were 28.7, which was below the 58.3 average reported a week earlier. Average daily solar flux was down by nine points from 87.4 to 78.4.

Geomagnetic indicators were higher, with the highest activity on September 17, when the planetary A index was 24 due to a minor geomagnetic storm triggered by a weak coronal mass ejection. The average daily planetary A index for the week increased from 7 to 9.1, and the average middle latitude A index went from 6.9 to 8.4.

Predicted solar flux for the next month is 90 and 92 on September 24-25; 95 on September 26-29; 92 on September 30; 84 on October 1-5; 82 on October 6; 80 on October 7-8; 78 on October 9-11; 75 on October 12-20; 80 on October 21-22; 82 on October 23-25; 84 and 82 on October 26-27, and 84 on October 28 – November 1.

Predicted planetary A index is 15, 8, and 20 on September 24-26; 35, 20, and 12 on September 27-29; 5 on September 30 – October 3; 8 and 12 on October 4-5; 5 on October 6-9; 12 on October 10; 5 on October 11-17; 8 on October 18-19; 10, 8, and 12 on October 20-22; 10 on October 23-24; 5 on October 25-30, and 8 and 12 on October 31 – November 1.

The autumnal equinox in the Northern Hemisphere occurred at 1920 UTC on September 22. Earth is bathed in approximately equal amounts of solar radiation over the Northern and Southern hemispheres, always a good sign for HF propagation. reported on September 23 that at 0442 UTC, sunspot group AR2871 produced a strong M3 class solar flare. A coronal mass ejection is headed our way but not directly toward earth. “A glancing blow might be possible on September 26-27,” said. If so, then the predicted planetary A index of 35 on September 27 may turn out to be a lower number.

Here’s the geomagnetic activity forecast for September 24 – October 19 from F.K. Janda, OK1HH. The geomagnetic field will be:

quiet on September 29, October 13, 16 – 18
quiet to unsettled on September 24, 27 – 28, October 1, 3 – 4, 7, 9, 12
quiet to active on September 25 ( – 26), 30, October 2, 8, 10 – 11
unsettled to active on October 5 ( – 6), 14 – 15, (19)
Active to disturbed: Nothing predicted
Solar wind will intensify on October (3, 8,) 11, (19)


* Parenthesis means lower probability of activity enhancement.

* Contradictory indications currently reduce the accuracy of the forecast.

N8II sent this update last week from West Virginia: “During the period when the SFI (10.7-cm Solar Flux Index) was near or over 100, conditions to Europe were somewhat disappointing on 15 — most of the time, a short opening of about an hour at 1400 UTC. September 16-17, the SFI was only 73, but there is now a minor to moderate solar storm in progress at 2400 UTC.

“As the storm was beginning, there was definitely enhanced high-band propagation to the higher latitudes. Around 1400 UTC, I easily worked 4S7AB, Sri Lanka on 15 CW, who was peaking S7, my first QSO with central Asia on 15 in a long time. Also, I worked OH0V, Aaland Islands around 1500 UTC, who was about S5. Geoff, GM8OFQ, in the Orkney Islands, north of Scotland (mainland) was easily 20 dB over S-9 on 17-meters SSB at about 1500 UTC on my dipole. I also worked HB0/DL5YM and YL on 15 CW peaking S-9. 7V7V portable on the beach in Algeria called about S-5. By 1600 UTC band conditions had drastically declined, but EU signals were very loud again on 20 at around 2000 UTC, including OH0V on CW at about 20 dB over S-9.”

N0JK wrote on September 17: “In your last propagation report, you mentioned KB0QZ working LU4HK on 10 CW. I think I know what was up. I neglected to send a report of the September VHF contest conditions. Sunday afternoon, September 12, there were reports of sporadic-E on 6 meters. I worked WA8QYJ (EL96) on 50.313 MHz FT8 at 2109 UTC on Es. KF0M (EM17) and WQ0P (EM19) also worked Florida stations on 6-meter Es at that time. I think it is plausible KB0QZ had a sporadic-E link to afternoon TEP on 10 meters. I also saw WW1L (FN54) spotted HC2FG at 2115 on 50.313 MHz. I suspect double-hop Es.
