Highlights of Solar and Geomagnetic Activity
24 - 30 May 2021
Solar activity was at very low levels on 24-25 and 30 May while an
increase to low levels occurred on 26-29 May. The majority of the
flare activity was from Regions 2824 (N20, L=196, class/area Dho/250
on 27 May) and 2826 (N24, L=215, class/area Dko/280 on 27 May). The
largest flare of the period was a C9/1f at 28/2313 UTC from Region
2824. Associated with this flare were Type II and Type IV radio
sweeps along with a CME observed off the west limb in SOHO/LASCO C2
imagery beginning at 28/2312 UTC. WSA/ENLIL modelling of the CME
showed the bulk of the plasma directed off the Sun-Earth line,
however there was potential for a glancing blow late on 01 Jun to
early on 02 Jun.
A greater than 10 MeV proton event (S1-Minor) began at 29/0300 UTC,
reached a peak flux of 15 pfu at 29/0320 UTC and ended at 29/0540
UTC associated with the aforementioned C9 flare on 28 May.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 24-26 May and decreased to normal-moderate levels on
27-30 May. The largest flux of the period was 1,530 pfu observed at
25/1825 UTC.
Geomagnetic field activity ranged from quiet to G1 (Minor)
geomagnetic storm levels. The period began with nominal solar wind
conditions and quiet levels through early on 26 May. At 26/1148 UTC,
an impulsive increase in solar wind speed from approximately 300-350
km/s was observed with a simultaneous increase in total field from
3-8 nT, marking the arrival of a possible conglomeration of CMEs
from 22-23 May. Total field continued to increase to 16 nT through
early on 27 May while solar wind speed increased to 400-450 km/s.
The geomagnetic field responded with unsettled to G1 (Minor) storm
levels the second half on 26 May, followed by quiet to active levels
on 27 May. Solar wind speed continued between 380-490 km/s through
the end of the period. Quiet conditions were once again observed on
28 May followed by quiet to unsettled levels on 29-30 May.
Forecast of Solar and Geomagnetic Activity
31 May - 26 June 2021
Solar activity is expected to be at very low to low levels on 31 May
- 11 Jun and again on 26 Jun. A slight chance for moderate
(R1-Minor) flares exist on 12-25 Jun with the return of Region 2824
to the visible disk.
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 18-22 Jun due to coronal hole high
speed stream (CH HSS) influence.
Geomagnetic field activity is expected to reach unsettled to active
levels on 01-04 Jun due to a combination of CH HSS effects as well
as the potential for a glancing blow from the 28 May CME late on 01
Jun to early on 02 jun. Unsettled to active levels are expected
again on 16-17 Jun, with G1 (Minor) storm levels likely on 16 Jun
due to recurrent CH HSS effects. Unsettled levels are likely on 26
Jun due to a possible reoccurring solar sector boundary crossing
(SSBC).

Glenn Hauser logs May 29-30, 2021
** BRAZIL. 9665.24V, May 29 at 2309, RVM is unsteady and slipped above 9665 after quite a spell on the minus side, music and then Brazuguese preaching, S6-S2 on the JRC.
9665.098V, May 30 at 0604, Brazuguese preaching, now measured on the Icom (Glenn Hauser, OK, WOR)
** CANADA [and non]. 248-MCW kHz, May 30 at 0623 UT, ND beacon WG with notably strong signal, far more than any other Canadian, and than my `local` Okies 255 SW and 350 RG which are JBA vs high storm noise level; and 341 EI Enid remains silent for weeks. WG is 1000 watts from WinnipeG; and never heard are 5 other listed Canadians on 248, two of which are to be decommissioned in August per dxinfocentre.com (Glenn Hauser, OK, WOR)
** CHINA. CNR1 jammer survey in the 12/13 MHz area, May 30 at 1421: 12500 Chinese at S5-S7; 12820 JBA carrier; 12880 Chinese S5-S7; 13130 Chinese S4-S5; 13530 JBA carrier vs CODAR (Glenn Hauser, OK, WOR)
** CUBA [and non]. 7335, 7345, 7355, 7365, 7405, May 30 at 0611, noise jammers of various strengths all against nothing since R. Martí closes two+ hours earlier! Or in case of 7405 never at all this season. 7335 jam is heaviest; 7365 lightest. Of note that 7345 is the RM DRM channel which quits at 0200, and when it`s on I never detect jamming which is so similar to DRM noise itself.
All this excessive jamming, just more evidence of Commie paranoia, and who gives a damn about polluting our SW bands totally unnecessarily? 7345 also has buried a JBA AM carrier, which during this hour only would be BBCWS English via Ascension. Something`s always wrong at the DentroCuban Jamming Command. Meanwhile there is no jamming on 7435 which is also an RM frequency earlier (Glenn Hauser, OK, WOR)
** CUBA. 13764, May 30 at 1426, spurblob out of RHC 13700-AM, telltale F# tone but no program audio; all approx., also traces around 13828, 13893, 13636 at ~64 kHz intervals. Something`s always wrong at RHC (Glenn Hauser, OK, WOR)
** NIGERIA. 7254.9+, May 30 at 0610, VON is on today with chants and presumed Hausa, S9+10/20. This thing could successfully provide a N American service if there were English on air before 0600, but then I would complain that it`s intruding into our hamband; while targeting only Africa Region 1 is legit. Of course they could equally serve NAm on an open frequency above 7300 (Glenn Hauser, OK, WOR)
** OKLAHOMA. 94.3, May 29 at 1930, 2125 and May 30 at 0115 UT chex, and *still* at 1814 May 30, open carrier/dead air from KLGB-LP, one of my closest transmitters, so maybe less of a QRM problem. Sibling KVBN-LP, co-located on same tower by an ex-church, continues nominal. Both are 100 watts ERP H&V, in WTFDA database as ``religious teaching`` but both are really mostly gospel rock now. Well, it is a ``holiday weekend`` so maybe will stay off Monday too (Glenn Hauser, OK, WOR)
** ROMANIA. 11730, May 29 at 2313, `Club Cultura` from RRI in Spanish, about museum restorations, S8-S5. No // found on same band; uplooked later in EiBi: 11730 & 9760 Galbeni to CAm; 11650 & 13750 Tsiganeshti to SAm listed (Glenn Hauser, OK, WOR
** U S A. 28281-CW, May 29 at 2322, W8EH beacon JBA, 8 watts to vertical with ground plane from Middletown OH, as recently logged but now the only 10m beacon audible; yet there are a few phone USB QSOs higher up like 28395, 28400, 28430. I had just found only one such on the 18 MHz band, 18140, but lots of skip with hets on AM CB 27 MHz frequencies. Today`s sporadic E MUFs mostly well below the FM band, but a few spixe not well positioned for DX to here (Glenn Hauser, OK, WOR)
** U S A. 28286.5-CW, May 30 at 1503, WB0BIN the only beacon JB audible, alternating fast and slow WPM, 7 watts from Sabin, Minnesota. As heard several times before. I keep getting only a few of the same ones by sporadic E vs hundreds listed on 10m at https://www.qsl.net/wj5o/bcn.htm mostly as C for allegedly continuous rather than Intermittent, and also # for confirmed active (Glenn Hauser, OK, WOR)
** U S A [and non]. WORLD OF RADIO 2088 monitoring: confirmed UT Sunday May 30 from 0321.5 on WA0RCR, 1860-AM, Gateway 160 Amateur Radio Newsletter, good via near-local KB0FX KiwiSDR, but with heavy storm noise despite none closer than western KS & OK, and along the NC/SC/GA coasts. Next:

Or 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. 7505, May 29 at 0155, S9+20/10 of dead air from WRNO. Lately has been inputting a stronger signal than before, modulated or not (Glenn Hauser, OK, WOR)
** U S A. 5850, UT Sun May 30 at 0100, `Encore` from R. Tumbril, SCOTLAND, via WRMI. VG via KB0FX MO remote for convenience since am at computer, but would also be VG direct. Also // 7780 which was back on air UT Sat after missing UT Fri for WOR during same hour. Much more diverse music this week than last week`s major composers. Playlist labeled 29/5: Poulenc, Fauré, Gavin Bryars, Hindemith, Francesco Mancini, Spiro, a polka-mazurka, Schubert. Synchro fake stereo mode gives it ``width`` with the notes cycling left and right, and now the SDR clix in this mode are less frequent and less obtrusive (Glenn Hauser, OK, WOR)
** U S A. 9940, Sun May 30 at 1712, WTWW-2 is on this new frequency ex-9930 but hardly ever used; gospel music, then YL with ``Atlas[?] Weather on WTWW`` for Nashville, also some other cities including Escanaba, Michigan, why? Random choice? This is S9-S7 and noisy, much weaker than the other WTWW-1 now on 9475 which is also seldom activated but more likely on Sunday holydays, which is SFAW not // 9940. Then Ted plugs ``USA Bible Academy`` on ``this website`` to avoid in-person COVID instruxion. 1714 a canned ID on 9940 for ``5085`` !! They still don`t have their act together. Both 9`s most likely to be active only weekends.
First time I`ve caught 9940, but A-21 HFCC registered available 24/7, 100 kW at 180 degrees while 9475 is 100 kW at 55 degrees, explaining why 9940 is so relatively weak here off the side close to 270 degrees from Lebanon. TWR Eswatini and Furusato no Kaze also 9940 at times.
I was bandscanning 17 down thru 9 MHz as during the stupid carace Indy 500, round and round, getting nowhere, signifying nothing --- but maybe some driver or spectators will be killed! --- would be a time if ever for WHRI to be turned back on as a former annual religious festival, but no sign of it on any band (Glenn Hauser, OK, WOR)
** VATICAN [and non]. 9645, Sun May 30 at 0607, VR liturgy Sunday-only in Romanian, harmonious responses, S6-S7; accompanied by:
9620, May 30 at 0607, Qu`ran at S9-S6, i.e. Algeria via FRANCE.
9420, May 30 at 0608, third ecumenical choice should be Greek Orthodox service from ERA but JBA (Glenn Hauser, OK, WOR)
UNIDENTIFIED. 9502.0-USB, May 29 at 2307, weak 2-way in Spanish INTRUDER; cambio (Glenn Hauser, OK, WOR)
UNIDENTIFIED. 12000, May 30 at 0559, JBA carrier at first assumed again 2 x 6000 RHC; but not //, talk here, music there just before 6000 cuts off. 12000 talk seems Spanish on USB, so maybe another 2-way intruder demodulated by the Cuba carrier (Glenn Hauser, OK, WOR)

A cuore aperto: Geloso G4/216 (1966)
Oggi mettiamo a cuore aperto un ben conosciuto ricevitore radioamatoriale italiano, molto più leggero. Costruito dalla Geloso intorno alla seconda metà degli anni 60, è l'ultima serie di apparecchi costruiti dalla ditta nostrana, prima del suo fallimento, avvenuto intorno al 1970. Progettato in collaborazione con Pippo Fontana, I1AY, il G4/216 è senz'altro il ricevitore che più tende ad avvicinarsi agli standard ormai imposti dal mercato americano ma ancor più da quello orientale, prepotentemente emergente, con prodotti di ottima qualità.

RF GAIN E VOLUME BF |
Circuito a doppia conversione di frequenza, il ricevitore copre le bande radioamatoriali dai 10 agli 80 metri. La prima conversione è ottenuta dal gruppo alta frequenza quarzato, mentre la seconda è affidata ad un oscillatore variabile. Questo sistema conferisce una buona selettività ed un alto grado di reiezione delle frequenze immagine. Impiega 10 valvole più una stabilizzatrice di tensione OA2, è dotato di un filtro a quarzo per aumentare la selettività soprattutto in CW.

Sul pannello frontale troviamo i comandi per lo stand by, ANL, esclusione del circuito AGC e per l' inserzione del calibratore a 3500 Khz, utile per allineamento scala e tarature. Ci sono poi i comandi di inserzione BFO ed il relativo controllo di PITCH, volume, RF gain, preselettore di antenna e sintonia. Sul pannello posteriore troviamo una morsettiera che serve a connettere due tipi di altoparlanti con diverse impedenze: 8 Ohm oppure 500 Ohm.

Nelle due boccole rimanenti, va collegato il comando di stand by per usare il ricevitore in unione ad un trasmettitore, in questo caso, il G 228. Il filtro a cristallo è di buona fattura e usando con attenzione il controllo di reiezione (PHASING) si ottiene una buona soppressione delle emissioni adiacenti (in cw ed ssb). Al contrario di molti apparecchi simili, il G4 216 ha la gamma dei 10 metri non suddivisa in sottogamme il che ne rende più agevole l'uso ma proprio per questo, è soggetto ad interferenze da parte di emittenti BC in gamma 9/10 Mhz; la presenza di un filtro collocato all'ingresso, attenua molto o sopprime del tutto questo disturbo.

La costruzione è realizzata in modo molto razionale, i cablaggi sono ben fatti e tutto il complesso risulta ben fatto. Nell'arco di mezz'ora il ricevitore raggiunge una discreta stabilità che consente di seguire qso in ssb o collegamenti in cw, ritoccando poche volte la sintonia, il filtro a quarzo, in posizione 4, riesce ad avere una banda passante di 500 Hz che consente una buona ricezione del cw.

Il circuito ANL è appena sufficiente a smorzare le impulsive ma introduce leggera distorsione audio. Alla prova, il ricevitore denota la sua obsolescenza rispetto ai prodotti in commercio negli stessi anni: la sintonia mossa ancora dal cordino con puleggia e condensatore variabile mentre esistevano i vfo a permeabilità, precisissimi e molto più stabili, l'assenza del rivelatore a prodotto per la ssb, la scala, molto bella ma affatto precisa e la selettività, non troppo elevata, che dà luogo facilmente ad intermodulazioni.

Il fascino degli apparecchi Geloso è senz'altro indiscusso ma, certo, non erano e non potevano essere all'altezza dei loro concorrenti stranieri, per motivi legati al costo e forse alla non volontà della Geloso di modernizzare la produzione.

Resta il fatto che le linee Geloso abbiano dato modo di operare a migliaia di radioamatori e di questo va fatto merito a Giovanni Geloso ed ai suoi collaboratori. La prossima settimana, metteremo a cuore aperto il ricevitore G4/215, predecessore del 216, poi toccherà al 214 e finalmente alle IMCARADIO.
