Highlights of Solar and Geomagnetic Activity
05 - 11 April 2021

Solar activity was very low throughout the period with only B-class
flare activity observed. No Earth-directed CMEs were observed in
available imagery.

No proton events were observed at geosynchronous orbit.

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

Geomagnetic field activity was at quiet levels on 05-06 April and
08-11 April. Unsettled to G1 (Minor) storm conditions were observed
on 07 April due to positive polarity CH HSS effects.

Forecast of Solar and Geomagnetic Activity
12 April - 08 May 2021

Solar activity is expected to be at very low levels during 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 high levels on 17-22 April due to recurrent CH HSS
effects. Normal to moderate levels are expected to prevail
throughout the remainder of the outlook period.

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic
storm levels on 17 Apr due to recurrent, negative polarity CH HSS
influence. Mostly quiet to unsettled levels are expected throughout
the remainder of the outlook period.

Glenn Hauser logs April 11-12, 2021

** ANDORRA [non]. 6180, April 12 at *1700, Moosbrunn on abruptly with anthem? by band, ID as R. Andorra in Spanish, rock music, French-speaking DJ. This is the much-publicized 40th anniversary salute to a long-gone SW station, arranged by Christian Milling of Germany`s shortwaveservice, who informs the WOR iog:

``Special program announcement: As some of you know, the legendary Radio Andorra was taken off the air these days 40 years ago in 1981 by the government. Some programs that were prepared couldn't be aired, most of the material is lost. Luckily, the playlist of the last planned hit-parade from April, 12th 1981 survived, thus it was never broadcasted. 40 years later this will finally be done. Next Monday, April, 12th 2021 at 17 UTC, exact 40 years later we will complete history. The show will be hosted by a DJ that started his career in Radio Andorra end of the 1970s. The program will be in French and broadcasted via Moosbrunn on a steerable LogPer Antenna directed at 270° towards the centre of France. All French-speaking countries in Europe should be covered in good quality.``

VG S9+40 signal at UTwente, and assumed zero signal direct at midday here. This is to last 3 or maybe 4 hours today. 1741-1751 pause for interview about the DJ and his subsequent career. Could not catch his name, which was mentioned only once in advance discussion I have not yet relocated.

There really should be some Catalan if not Spanish, English. Here`s some Catalan with the playlist of 50+songs, found by roger: https://www.bondia.ad/cultura/lultim-hit-parade-de-radio-andorra

My 1960 QSL card for R. Andorra, 5972, can be viewed, #14 & 15 at http://www.worldofradio.com/QSL.html (Glenn Hauser, HBD 76, OK, WOR)

** CHINA [non?]. 11675, April 12 at 1504, S9-S7 in Chinese, then music, definitely only one signal but this time it smax of RFA as scheduled this hour only via SAIPAN, rather than of a CNR1 jammer (Glenn Hauser, OK, WOR)

** CUBA. 11850, April 12 at 0132, RHC is S9/+10 of dead air, Spanish or English? Something`s always wrong at RHC (Glenn Hauser, OK, WOR)

** CUBA. 5990, April 12 at 0536, undermodulated RHC English S9+30 instead of 6000! Presumably confused while 5990 is intentional earlier for CRI relays at 23-01. Aoki shows both from Quivicán, but must be separate units as both scheduled between 00 and 01. In any event, RHC still gets Mali 5995 adjacented from one side or the other if after 0600.

Now at 0536 I check the other RHCs: 6060 S9+ same undermodulation, and NO buzz for a change; 6100, S9+10/20 but undermod; 6165, S9+10/20 but noisy. 5040, S9+20/30 even English. So here we have The Cuban Five all in axion. Something`s always wrong at RHC (Glenn Hauser, OK, WOR)

** CUBA. 13490-trace, 13560 vs local ISM pulsing, 13630; 13769, 13839, 13909, 13979-trace, April 12 at 1419, FMish spurblobs but with no program mod, just F# tones, out of 13700-AM RHC Spanish. Not in the order tuned, at 69-70 kHz intervals. All gone by 1500. Something`s always wrong at RHC (Glenn Hauser, OK, WOR)

** CUBA [non?]. 9805.4-CW, April 12 at 1510, beepstrings much stronger than residual jammer noise against OCB which is currently on 9805 only at 10-13. They are continuous at steady rate of 100/minute but don`t last a full minute between pauses. Individual strings last anywhere from 22 to 35 to 57 beeps, per three different counts; and during each string there is one out-of-step pause. These continue to be associated with after-hours Cuban jamming frequencies, as recently heard near 11860, 11930, 13605. SAWA.

This also reminds me of the old Soviet jammers, which would ``ID`` by two CW letters at least once a minute; the one which still stix in my mind was ZG: --../--. Probably secret random coding, but now that reminds me of Zhigulevsk, except Zh is not the same letter as Z. I researched some websites about Soviet jamming, a few mentioning the ID setup, but not ZG. But I digress (Glenn Hauser, OK, WOR)

** U S A [and non]. WORLD OF RADIO 2081 monitoring: confirmed Sunday April 11 from 2000 UT on IRRS via Challenger Radio, Italy, 594 kHz, as heard via nearby Noale KiwiSDR, S9+15 with Moroccan het on plus side so tuned to LSB; also audible at UTwente, S9+10 but noisier, autonotch deletes the het.

WOR 2081 also confirmed Sunday April 11 after 2200 on Area 51 webcast --- but cannot find any modulation from WBCQ 6160, tho remote detects the carrier, noisy at Rochester offset -92 Hz (while 7490 -66 Hz with UBMP is OK). Here I measure it on 6159.91, carrier with no audio. By 2343 recheck via Rochester and Alexandria, now it`s musicking. Tsk2: last week on A51 it was previous week`s WOR; this week no SW mod. At 0124 Apr 12 remeasured here on 6159.910.

Also confirmed Sunday April 11 at 2300 on WRMI 7780, S9+5/15 to UTwente.

Also confirmed UT Mon Apr 12 at 0030 on WRMI 7730, good direct.

Missed checking Mon Apr 12 at 0230 on WRMIs 5800 & 7780; anyone?

One may also contribute, by MO or check in US funds on a US bank to Glenn Hauser, P O Box 1684, Enid OK 73702 (Glenn Hauser, OK, WOR)

** U S A. 3215, Apr 12 at 0546, WWCR is S9+20 of dead but noisy air instead of TOMBS, now more apropos a monicker than ever. 4840 is OK with oldtimeradio; 5890 with TOMBS like still on 5850 WRMI. I notice that a lot of times now, they are playing BS attempting to sing, sometimes lapsing into glossolalia. That must mean he`s divinely inspired with godspeak! (Glenn Hauser, OK, WOR)

UNIDENTIFIED.13557.7-LSB, April 12 at 1417, 2-way in Spanish, impinging into the ISM band (Glenn Hauser, OK, WOR)

Glenn Hauser logs April +11, 2021

** ALGERIA [non]. 13815, April 11 at 1822, S6-S7 Qur`an: RTA via FRANCE, only thing ever on this frequency, this hour only per Aoki (Glenn Hauser, OK, WOR)

** ANTARCTICA. 15475.98-RCUSB, reply to my report of no signal from LRA36 when I checked after 1530 Wed April 7, but was heard earlier, when? ``From: Giovanni Lorenzi --- Hi Glenn, the time of listening LRA36 15476 kHz on April 7 was 1400-1530 UT: first I have used CX8BIT SDR kiwi in Montevideo Uruguay with signal rating SINPO 35555 and after SDR in Caruaru (Brazil) PY2PE and finally LU4EEC in Argentina Buenos Aires with poor signal. 73 de Giovanni`` (Glenn Hauser, WOR)

** CUBA. 6060, April 11 at 0623, RHC English still with humbuzz, but we have choices between the other two: 6100 good S9+20, 6165 same level but less modulated. 6000 off already. Something`s always wrong at RHC (Glenn Hauser, OK, WOR)

** MALI. 13799.44v, April 11 at 1833, JBA carrier with trace of Arabic talk, I can now confirm as spur out of S9+35/40 Bamako 13685 relay at 1830-1930 only of CRI, as heard yesterday on exactly the opposite side of 13685, and again today. 13570-USB tuned in by 1828 on UTwente SDR, nothing, but by 1830 I detect the het, and tho JBA carrier, get UTw AM Synch to lock onto it at 13570.735, and it`s slowly drifting downward by the Hz to 13570.700 as transmitter warms up. Fundamental with same behaviour, 13685.075, down to 13685.060 etc. And the upper spur: 13799.444 down to 13799.431, etc. During a 60-second span, this one loses 2 Hz, and I assume all will eventually become mores stable (Glenn Hauser, OK, WOR)

** SWEDEN [non]. 15510, April 11 at 1819, African language mentions Obama, S9/+10. Aoki shows it`s Radio Sama = IBRA Radio via Woofferton UK in Fulfulde this semi-hour, preceded by Tigrinya, followed by Arabic (Glenn Hauser, OK, WOR)

** U K. Woofferton relays of R. Sama - see SWEDEN [non]; of VOA, see USA [non]

** U S A [non]. 15660, April 11 at 1820, language mentions Amnesty International in English, S9+10 with music background. Aoki shows it`s VOA Amharic this hour via Woofferton UK. VOA also on 15660 from various other sites before and after this hour (Glenn Hauser, OK, WOR)

** U S A [and non]. WORLD OF RADIO 2081 monitoring: confirmed UT Sunday April 11 at 0331 on WA0RCR, 1860-AM, about 3 minutes into so started about 0328. S9+20/30 received here direct. Next:

** U S A. 5085, UT Sun April 11 at 0030 & 0045 chex, WTWW-2 rock music distorted instead of `Theatre Organ Under the Arch`, so no need to go to the webcast, which is still blocked as a dangerous site anyway (Glenn Hauser, OK, WOR)

** U S A. 13845, April 11 at 1821, WWCR is S9+10 here with YL huxtress, presumably PMS, discussing circumcision; while 15825 is usual JBA carrier. Therefore the sporadic E MUF is somewhere between them; an hour later there`s a 25 MHz patch over NW Georgia on DXMAP (Glenn Hauser, OK, WOR)

** VANUATU. 11835, Ron Howard replied April 8 to my report of how R. Vanuatu sounds: ``Hi Glenn, Normally RV does start the news about one minute or so after the hour. Their intro is indeed always with the same theme music; consisting of indigenous horns and drums, making for a very unique sound; ending the news with a different theme music. Ron`` (Glenn Hauser, OK, WOR)

A cuore aperto: BC603 (1940)

Come promesso, eccoci a parlare di un ricevitore a suo modo storico: si tratta del noto BC603, risalente al 1940.

Facente parte della stazione SCR 508, comprendente anche il trasmettitore BC 604 ed il secondo ricevitore BC 683, il BC 603 fu il primo ricevitore in FM realizzato per l'esercito americano.

BC 603 MOUNTING FT346 

Destinato alle comunicazioni a corto raggio nei veicoli da combattimento (carri, mezzi corazzati, ecc.), è costruito in un solido cofano metallico, con il frontale protetto da una pesante griglia che ne rende appena accessibili i comandi e controlli.

SCR 508 - sono visibili il BC604 - BC603 e BC683

Oltre che nei mezzi suddetti, la SCR 508 era destinata anche alle comunicazioni tra battaglioni, tra carri, tra battaglione e comando ed ai carri comando, in questo caso, unitamente al ricevitore BC 683. Supereterodina, copre la frequenza da 20 a 27,9 Mhz in FM, è dotato di squelch, controllo di sensibilità d'ingresso, esclusione altoparlante, uscita cuffie, commutatore interfono/radio e comando per l'isoonda con il trasmettitore.

FRONTALE SMONTATO PANNELLO FRONTALE LATO CABLAGGIO PANNELLO FRONTALE contattiera
PANNELLO FRONTALE trasformatore uscita ed altoparlante PANNELLO FRONTALE deviatori ed interruttori PANNELLO FRONTALE finestra sintonia e calibrazione

Lateralmente si trova il foro per l'accordo di antenna, tramite compensatore. La particolarità risiede anche nel sistema di sintonia che può essere manuale ma anche prefissata tramite 10 pulsanti posti sul lato sinistro del frontale; tramite un sistema di cammes e rinvii precisissimi, si potevano memorizzare (meccanicamente) 10 canali e sbloccando il sistema, si escludeva la ghiera di sintonia e si utilizzavano i pulsanti.

Questo era necessario dato che il trasmettitore BC 604 non aveva vfo; la sintonizzazione avveniva tramite quarzi, a frequenza fissa. Molto massiccio e pesante, era stato pensato per la vita nei carri armati, noti per non essere molto gentili nei modi, doveva resistere a sollecitazioni molto forti senza cessare di funzionare.

La larghezza di banda è enorme, circa 50 kilohertz ma ha la sua motivazione proprio a causa delle condizioni estreme in cui questa radio doveva operare: nei carri, tra cannonate date e prese, scossoni, manovre al limite del ribaltamento, urti fortissimi e mitragliamenti senza perdere la sintonizzazione e quindi, venne decisa una larghezza di banda notevole.

 

La media frequenza è fissata a 2650 kHz, impiega 10 valvole con uno stadio in alta frequenza, l'alimentazione è data tramite dynamotor DM 34A per i 12 volts e DM 36A per 24 volts. Veniva montato, tra gli altri mezzi, nei carri leggeri M24 e qui ho allegato le istruzioni per il montaggio a bordo del carro stesso.

Il mounting era l' FT 237 che conteneva i due ricevitori ed il trasmettitore. Per il solo ricevitore, esisteva il mounting FT 346. Il peso  è di 35 libbre, circa 17 Kg.

Cosa si possa fare con un BC 603 oggi, non è molto: l'esemplare in mio possesso, oltre ad avere l'alimentatore da rete, che toglierò non appena troverò il dynamotor originale, ha la modifica, semplicissima e non invasiva, per poter ricevere anche la AM e così è possibile seguire qualche sparuto qso in 11 metri, quando ce ne sono o se no, a parte un paio di broadcastings nella gamma più bassa, non c'è molto altro da ascoltare.

Vicino alla mia abitazione c'è un enorme plesso ospedaliero, forse il più grande di Roma, in cui il sistema cercapersone lavora ancora in banda 11 metri ed ogni tanto posso ascoltare qualche conversazione tra i reparti. Oltre questo, con il 603, non si può fare a meno che non si abbia un corrispondente con una SCR 508 per fare QSO. A breve mi arriverà il trasmettitore BC 604 che verrà prontamente aperto ed illustrato.

Spero che anche il BC 603 abbia suscitato interesse: la prossima settimana torneremo alle radio "civili" ma per il futuro vi prometto un altro apparato militare veramente molto bello, interessante ma molto grande e pesante, quasi 100 Kg, datato 1943 e funzionante. Abbiate fede... organizzerò il trasporto e ve lo mostrerò "a cuore aperto". Altri, ne arriveranno.
