Surprise, surprise, RHC on 7350 kHz.
CUBA RHC Spanish now on 7350.001 kHz from Bejucal site.
But not at 11.00 UT check, nor at 11.12 UT,
noticed this channel later after 12 UTC. 12.05-12.15 UT noted
on S=9+25dB in Edmonton Alberta Canada remote Perseus installation.
gh: supposed to be on 7340, so change or error?
Noticed also in 22 mb RHC now - VERY SURPRISING -
not on A-season 13780 kHz channel, but on 13740 kHz again,
broadband 20 kHz wideband audio !
co-channel and - latter - covered as always since years by
TDF RFI Issoudun France in northern summer A-seasons.
gh: also 13740 here todaym gia== before 1400 -- they can`t decide whether to use 13780 or 13740. Not surprising; I have reported this a few times before.
On 25 and 22 mb also noted some scratching audio signals
annoying in ranges
CODAR transmissions
11857 to 11865 kHz and
11926 to 11933 kHz at 11.21 UT,
13424 to 13477 kHz at 12.52 UT
gh: the first two are extra Cuban jamming markers beyond Marti hours on 11860, 11930, surely not CODAR. Slow swish-swish pulsing sound of CODAR is quite different from Cuban jamming pulses.
Also - I guess - 13603 to 13609 kHz - some scratch audio
? intermodulation appears from Bejucal Cuba site ?
Low -104dBm on threshold level in eastern US states,
but stronger noted in western Canada at Edmonton remote SDR site.
gh: Ditto, jamming against no-Marti-yet on 13605
Othe scratches of audio intermodulation mix of UNKNOWN txion center at 13.03
UT on 13571, 13682, and 13820 kHz.
gh: 13571 maybe spurblob out of 13700, I had later on different ranges.
13820 yet more residual pulse jamming against an unoccupied Marti frequency this season.
The incompetence, hostility, carelessness, and wastefulness of the Cubans is boundless.
