Glenn Hauser logs December 6, 2009 part II

** CHINA [and non]. 7105, intruder in the exclusive worldwide 40m hamband, Dec 6 at 2216 with alternating YL in Chinese, OM maybe Chinese but sounded like a different language. Per Aoki this is a 100 kW Sound of Hope frequency from Taiwan during this hour only, but always jammed and more likely to have been hearing CNR1 instead. Only other broadcaster audible 7100-7200 was Guinea on 7125, in French at 2217 (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. En Contacto, the DX program of RHC, Sunday Dec 6 at 2152 on 13790 with mailbag for rest of show until finished at 2157 so must have started at 2142. When 13790 went into brief fades, long-path echo could be heard, some 38 Megameters away.

Checked all the other frequencies and found the other kind of echo, between transmitters not precisely synchronized because they are from the two different sites and/or with different feed routing. Synchro with 13790 were 6110 and 11770. An echo apart from those but synchro with each other: 13770, 11800, 11730, 9660. Meanwhile, 11760 was in separate musical programming (Glenn Hauser, OK, DX LISTENING DIGEST)

** GABON. 9580, Africa Numéro Un, Dec 6 at 2203 in French news of Somalia, VG signal. I also had them well at 0700 as in previous report. I am beginning to wonder if during the last several months they had been running reduced power and have just recently resumed full power, 500 kW per WRTH. We are also still waiting for them to reactivate a second transmitter (WRTH shows three), and bring back daytime frequencies 17630, 15475. BTW, there are no Gabon registrations in HFCC (Glenn Hauser, OK, DX LISTENING DIGEST)

** INDIA. AIR GOS, 7550 // 9445, good signals roughly equal but with polar flutter, Dec 6 at 2157 with what I can only describe as lite music, not Indian, such as Girl from Ipanema at 2159, which had to be cut off at 2200 for ID and news. Could also // them to much weaker 6180. More lite music until all signed off at 2230 after listing frequencies to AuNZ at 1000 and one other target (Glenn Hauser, OK, DX LISTENING DIGEST)

** PHILIPPINES. 11560, VOA news in English about Thailand, Dec 6 at 2212, fair with flutter. At 2301 had improved to VG signal but `hollow` sound indicating multipath reverb rather than long/short path which makes more pronounced echo. This is on that 21 degree antenna from Tinang, i.e. along the north coast of Alaska, across Canada thru Sioux Lookout, SW Ontario, Michigan, South Carolina (Glenn Hauser, OK, DX LISTENING DIGEST)

** SAIPAN. 12090, Vietnamese songs at 2254 Dec 6, fair signal aside BBC 12095. At 2258 switched to Christian hymn in English, “All Hail the Power of Jesus` Name . . . And Crown Him, Crown Him, Loo`oord of All“, making me suspect it was a gospel huxter; brief Vietnamese announcement and convenient English ID for KFBS, Saipan, off at 2300* sharp. EiBi, Aoki and HFCC all agree that the only occupant of 12090 at any time is KFBS at 2230-2300, 278 degrees, so there are 23.5 hours available for some other station needing to escape from interference (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. WINB, 13570, which was outputting spurs the morning of Dec 6, still doing so the afternoon at 2150, peaking as before around 13510, 13540 and 13600. Must have switched to 9265 at 2200, since there it was at 2214 but with no spurs and slightly better modulation on this fundamental (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. Tried to listen to Marion`s Attic on WBCQ, 7415, Sunday Dec 6, from 2218 tune-in. Fair at first but before the hour was over became unlistenable. DentroCuban Jamming Command against Radio Martí on 7405 was putting out regular noise pulses at plus and minus 10 kHz, as happens very frequently, due to at least one of their multiple jamming transmitters suffering from spurious output.

No, these were not scratches on Marion`s records, which also can occur at a steady repetitive rate! There was also a subaudible heterodyne indicating co-channel broadcast interference. By 2237 WBCQ was losing out to the DCJC noise, and by 2242 the CCI in Chinese had reached WBCQ`s level and soon surpassed it as WBCQ was also fading down. At 2245 there was also a brief continuous tone, and then a few dots and dashes, after which I gave up.

The co-channel interference is sadly to be expected, since someone at HFCC signed off, agreeing for BBC in Mandarin via Thailand to use 7415 during this hour, necessarily requiring ChiCom jamming, which is probably what I was hearing with the CNR1 program, rather than BBC itself. (And during the hours preceding and following, CRI itself is on 7415!)

The adjacent channel interference from Cuban jamming is also to be expected, as any station is just asking for it by operating only 10 kHz away from any Radio Martí or other service jammed by Cuba (VOA, Radio República, WRMI). This could be solved by one or the other moving away, but I doubt that either would be willing to relinquish a longtime familiar and traditional channel. So everybody loses (Glenn Hauser, OK, DX LISTENING DIGEST)
