Glenn Hauser logs February 24-25, 2013

** BOLIVIA. 4716.68 approx., Feb 25 at 0110, best signal in the 4700s tonight is here, presumed R. Yatun Ayllu Yura, in Yura, allegedly 1 kW. Some music is audible, while the rest are mostly carriers. Previously rounded to 4717v, this time I measure it as closely as possible using the 40-Hz per click method on the DX-398 on the porch with battery power, after calibrating it to WWV on 5000.000. Winter storm with thunder approaching from the TX panhandle is producing some lightning crashes on these lower frequencies (Glenn Hauser, OK, DX LISTENING DIGEST)

** BRAZIL. Re my previous report, Jorge Freitas points out that Rdif. Macapá is in Amapá state, not Acre, which I got by referring to the `Carmen Miranda Report` in DXLD 13-08 instead of the WRTH 2013. Corrected:

4915, Feb 24 at 0659, music and soon ID including ``4915, onda curta``, a website in .br, at 0700 ``Macapaense`` and ``Macapá``, so I am confident it`s not R. Daqui but really the other 4915, Rdif. Macapá, ZYF360 in Amapá. Signal is second only to Pará on 4885, both 24 hours, tho Macapá supposedly has a 25 to 10 kW power advantage (Glenn Hauser, OK, DX LISTENING DIGEST)

** GUIANA FRENCH. 9490, Feb 25 at 0102, the RMI R. República transmission is back to full strength, way over jamming and with good modulation; so if the plus/minus 116 kHz and other spurs are still radiating, they should be audible tonight. However, 9606 is blocked by bigsig from WHRI on its single night broadcast UT Mondays only, and I can`t detect it in the sideband. 9374 on the lower side is in the clear with no blob detectable. There is also some quite different weak OTH radar noise pulsing circa 9360-9385.

However2, the fundamental has another problem, perhaps exacerbated by good propagation: splashing out to plus/minus 23 kHz or so, i.e. gradually declining out to 9467-9513. I would not want to be another station within that range.

Same transmitter previously put out same 116 kHz separation spurs from very strong 5960 after 0200 for the NHK Japanese relay, so checking around that at 0228 UT Feb 25: 6076 and 5844 are clear, nor can I find the +36 kHz spur around 5996, nor the -71 spur around 5889. But there is a lot of other noise on the band, especially around the other former spurspot 5924 as well as 5996.

Overall, as far as I can tell, the GUF spurs have been suppressed, perhaps as of Feb 23 or so (Glenn Hauser, OK, DX LISTENING DIGEST)

** PERU [and non]. 5980.0, Feb 25 at 0059, DentroCuban Jamming Command is messing up the frequency with noise pulses, unlike many nights lately; can`t even hear the CNR1 jammer closing timesignal at 0100*, but the R. Chaski carrier remains audible with BFO under the noise, and this time as expected, it cuts off at 0106:58.5* which is 5 seconds later than last night (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 4593.5-USB, Air Force MARS net encountered Feb 25 at 0055; NCS seems AFA1TN (or TM?), about to close it with the group call NES2 given fonetikaly unlike his own call.

Googling on AFA1TN leads to a Silent Key:

while AFA1TM leads to no significant top hits, so maybe AFA1TN call has now been reassigned (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 9605, Feb 25 at 0102, WHRI is on strong with some pseudo-network news on the blizzard about to strike us, as I am checking for the Guiana French [q.v.] spurblob around 9606. WHRI 9605 usage is registered, and so far heard, only on UT Mondays, tho probably tested one other night with KBS World Radio in Spanish to S America (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 5085, Feb 25 at 0108, WTWW-2 is on-again with country music, presumably Ted Randall once again doing his evening show on Sunday night = UT Monday, instead of original Saturday night = UT Sunday (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 5050-USB, Feb 25 at 0109 check, WWRB is on again in pure USB, but g.h. of the moment is the one with lots of background noise keeping the SB modulated even his during pauses. At this point it will be more newsworthy if it goes back to AM, or goes off (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 4849, Feb 25 at 0057, again tonight I am hearing a het or tone test estimated close to 1 kHz with the DX-398 on the porch, where without continuous tuning it`s harder to tell than on the FRG-7 whether this is a DSB tone or a het on one side or the other, but I think it`s only the low side vs carrier on 4850. After 0059 obscured by squeal and splash from 4840 WWCR, but barely audible at 0101. Again PBS Urumqi and AIR Kohima are the two broadcasters listed on 4850, but a utility could also be involved. Would appreciate listeners in Asia checking around this time, and also in Latin America in case it`s something from there (Glenn Hauser, OK, DX LISTENING DIGEST)

[all logs in this report, except the Brazilian correxion, were on the DX-398 with random wire around eaves of porch; mild temp ~lo 50s]
