** ANGUILLA. 6090, May 11 at 0537, C.B. is back on after missing a few hours earlier, audiblizing Brazil (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 6000, May 11 at 0536, open carrier/dead air from RHC English; nominal on 6165, 6000, 6060, 5040, Arnie science segment ending (Glenn Hauser, OK, DX LISTENING DIGEST)
** SOUTH AFRICA. 11605, May 11 at 0542, open carrier/dead air, fair with flutter. No doubt the only thing scheduled, but failing to modulate, RFI French, 100 kW, 345 degrees from Meyerton at 0500-0600 (to be followed by another hour but shifted 3 degrees to 342, per Aoki; why?) (Glenn Hauser, OK, DX LISTENING DIGEST)
** SOUTH CAROLINA [non]. 9370, May 11 at 0540, WWRB is still on here with TOM, but faded to very poor level, no 3185. And BS also still on 12105 from WTWW-3, faded to poor level but more readable than 9370. By 1300 recheck, 12105 is off again, and 9370 still on (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 5830, May 11 at 1308, WTWW-1 is still on night frequency with SFAW; by 1401 next check it`s on day`s 9475. And nothing from WTWW-2 or -3 (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. This morning at 1303 and still at 1405 UT, I am hearing what sounds like DRM, centered below 13835 but above 13830. Certainly has not been there before. DRM-capable monitors, please check this out (Glenn Hauser, OK, 1418 UT May 11, dxldyg via DX LISTENING DIGEST)
Then discussion with Christopher ``Fibber`` Rumbaugh, DRM enthusiast: ``Nothing here Glenn, but perhaps it is Europe and I am too far out West. Is it the characteristic OFDM waveform of 10 kHz?``
Was not as wide as 10 kHz; just going by the sound of it. No longer heard at 1427 check. Suspect it`s Chicom jamming against RFA Tibetan at 11-14 via Tajikistan on 13830 [where there had been a JBA carrier]. When DRM is used for jamming, is there any intelligible info contained, like ID info? Glenn
Fibber: ``There is likely the ID information imbedded, but the on-channel noise could very well obliterate it - Even the FAC (broadcast format info) let alone the SDC (where the ID lives) and the MSC (the audio and other program content). I was getting AIR Delhi yesterday but no ID made it through. Too weak and too many hops to be stable, I think`` (Glenn Hauser, OK, DX LISTENING DIGEST)
