[HCDX] Glenn Hauser logs February 11-12
** CUBA [and non]. The 5025 transmitter is having more and more down time. Feb
11 at 0540 just an open carrier with hum. RHC was OK on 6000 with Arnie plus
usual squeal. But guess what --- NO jamming audible on R. Martí, 6030 and 7405.
This was during a drama produxion; not sure if that had something to do with
it. But at 0557 recheck, jamming was back on 7405 but R. Martí was atop, while
on 6030 at 0602, heavy jamming was atop RM. Perhaps a short-lived power failure
at certain sites (Glenn Hauser, OK, DX LISTENING DIGEST) See also VENEZUELA
[non]
** GABON [and non]. Afropop music distraxion: Feb 11 at 1508 was on 17660; Feb
12 at 1509 also on 17660, but with heavy flutter, in disturbed propagation
conditions; however, ANU Moyabi on 17630 was steady as usual with no flutter,
altho some CCI from Mali.
This has happened on previous occasions, making one wonder if Afropop and ANU
are really from the same site, with such different reception characteristics.
One would expect the flutter to come over a much higher-latitude path. At this
time on the 16m band I did not find any other signals with such flutter; among
the normal ones checked were 17725 Libya/France, 17770 South Africa, 17830
Ascension, 17620 France, 17595 Spain, 17525 Greece. Sa`udi Arabia with Qur`an
at 1525 had some flutter tho much stronger signals on 15435 // 15425 and so did
a weak signal from DW in German on 15275. Then at 1529 I noticed VOA News Now
on 17895 had similar flutter to 17660. Sites for these: 15275 Rwanda, 17895
Botswana, certainly neither of them hi-latitude.
Afropop on 17630 went off at 1531* as usual after a semiminute of dead air.
During this time I had the BFO on and noted that not only was there a flutter
in the amplitude of the signal, but also in the frequency, which I believe is
attributed to Doppler effect in the unstable ionosphere.
Perhaps the amplitude flutter can be explained by the azimuth of these
particular transmissions, not directly toward us, but going north towards a
disturbed area of the ionosphere, and part or most of the signal being
scattered back toward us? 15275 is 30 degrees, and 17895 is 350 degrees per
HFCC. Who knows what on 17660, but it should be somewhere in that area if it`s
aimed from Gabon toward Libya as jammer/distraxion. 17630 is missing from the
latest HFCC, but previously was shown as 307 degrees, which is more favorable
for NAm, somewhat south of due NW (Glenn Hauser, OK, DX LISTENING DIGEST)
Solar-terrestrial indices for 11 February follow. Solar flux 75 and
mid-latitude A-index 1. The mid-latitude K-index at 1500 UTC on 12 February was
3 (25 nT). No space weather storms were observed for the past 24 hours. No
space weather storms are expected for the next 24 hours (SEC via DXLD)
** GREECE. ERA5 test, now believed to be from the Olympia Radio maritime site,
Feb 12 at 1512 on 15630 had frequent breaks in transmission, and when
transmitter stayed on there were also quick breaks in modulation. At 1523 I
found that 15630 was off more than it was on. // 17525 Avlis with no such
problems. If they can`t get the Olympia utility transmitter to funxion in AM,
these tests will have been fruitless. Rechecked at 1602, I found that 15630 no
longer was breaking up, presumably after Avlis resumed that frequency, probably
the transmitter which had been on 17525 but no longer heard (Glenn Hauser, OK,
DX LISTENING DIGEST)
** GUIANA FRENCH. TDF DRM test was back on 17870-17875-17880, Monday Feb 12 at
1507 (Glenn Hauser, OK, DX LISTENING DIGEST)
** JORDAN. 11690, Feb 12 at 1501-1503 with news headlines in English, 1503 TC
at 3 minutes past 5 pm, ``Radio Jordan 96.3 FM``. Some flutter on this signal,
but strong enough to edge out the RTTY on low side, and no sign of HCJB usually
dominating 11690 (Glenn Hauser, OK, DX LISTENING DIGEST)
** LAOS [non]. Hmong Lao Radio, 11785 via WHRI, Sun Feb 11 at 1445 with a
cappella chants and bird, nature sounds. This is really exotic, lovely, stuff
occupying parts of the Sat & Sun 1400 hours, and here on a big clear signal. I
urge people to listen in, if they haven`t already. 1450 into talk with guitar
background (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. WTJC missing again from 9370, Feb 11 at 1512; at this hour there was
too much noise to decide whether WBOH 5920 was also silent. Perhaps they have
got religion and now observe Exodus XX: 10 and XXXV: 2? 9370 still not heard
around 0700 Feb 12, but was back on at 1541 with Roloff. Until now, WMLK has
been the only US SW station observing the Sabbath, tho in that case it`s
Saturday (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [non]. Checking VOA`s new Somali service on its first day, Feb 12: at
1628, 15620 was weak with flutter, and 13580 inaudible. At 1632, nothing on
15620 during scheduled half-hour break. But I could hear neither of them at
next check 1724. What are the sites?
The VOA Swahili service does continue, best on 17580, Feb 12 at 1629 with open
carrier, 1630 VOA theme, opening in Swahili, fair. Could only detect very weak
carriers on other listed frequencies 17705 and 21480. At 1726, 17580 was fair
with hum, and VOA theme, mentioning Robert Gates; a bit of audio on poor 21480.
Also checked the M-F service to Zimbabwe. At 1725 Feb 12, new 15775 was fair in
presumed Shona talk; no music jamming audible here tho still reported from
Zimbabwe. Promptly at 1730 VOA ID and into English with Studio 7; said if MW
909 is jammed, tune to SW 4930, 11815 or 15775 (Glenn Hauser, OK, DX LISTENING
DIGEST)
** VENEZUELA [non]. Sunday, Feb 11, at 1512, there was nothing on any of the
usual five frequencies for Aló Presidente via Cuba --- 17750, 13750, 13680,
11875, 11670. However some minutes before 1500, there was something in Spanish
on 13680, presumably this with an early close (Glenn Hauser, OK, DX LISTENING DIGEST)
