Glenn Hauser logs June 27, 2021

** CHINA. CNR1 jammer survey, June 27 at 1411: 13530 JBA; rest JBA carriers on known frequencies: 13160, 13130, 16100; none in the 11 MHz WOOB area (Glenn Hauser, OK, WOR)

** CUBA [and non]. 13820, June 27 at 1349, residual pulse jamming against nothing since this is R. Martí`s B-season-only frequency; now it`s blasting in on 13605, obscuring here any possible jamming. Something`s always wrong at the DentroCuban Jamming Command (Glenn Hauser, OK, WOR)

** ETHIOPIA [non]. Re June 25 report: ``I too had the white noise jamming on 17750 after 1500 today via UTwente, and a JBA carrier amid it. Are we only assuming 17750 has to be for Ethiopia since it`s jammed this way? Nothing listed anywhere. In EiBi I find this which we need to check whether still on 17870 - might have moved. ``1500 1600 ETH DimtseTigray MediaHouse TIG EAf 17870/F[RANCE]``

17750, June 27 at 1515, via UTwente again JBA carrier amid DRM-like noise jamming. More of the understation is audible via Kuwait SDR, 1521 HOA music and reverb announcement. At both locations there is *no* signal on 17870, so further evidence that the 17750 transmission is the one listed for 17870: Dimtse Tigray Media House.

17750 programming and jamming have continued past 1600, 1645+ unlike the one-hour ex-17870 schedule from 1500.

Wolfgang Bueschel was also monitoring, and convinced the jamming is from the Gedja, Ethiopia site. He and I both heard a few seconds` pause in jamming at 1530 for them to reconfirm target still running.

How effective could jamming from inside Ethiopia be on such a high frequency due to skip zone? Could the Ethiopians be getting help from an outside site?

Toward the end, 17750 programming well audible into Kuwait until cut off at 1658*. Noise remains but now is not the jamming which may have stopped earlier (Glenn Hauser, OK, WOR)

** U S A. 13565-CW, June 27 at 1351, K6FRC HIFER beacon repeating nothing but ham callsign, JBA vs CODAR swirshes. Bandscan across here virtually every morning unfinds its 1.8 milliwatts, so whenever audible is notable, and always around 1400. On June 3 I had a trace of CW but not definite ID like today. Last log previous to that was May 9 (Glenn Hauser, OK, WOR)

** U S A. 15825, June 27 at 1417, WWCR-1 gospel huxter is the SSOB rather than JBA, tnx to sporadic E boost; enough to tell that it`s a bit overmodulated, distorted, but no squeal (Glenn Hauser, OK, WOR)
