Another check on Monday March 10 at 10.22 UT :
thanks Zach re KIWI_net SDRs reception remotedly at Kuwait ham radio society too ...
SAUDI ARABIA 11934.894 kHz measured remotedly on Perseus SDR unit
in Doha Qatar ME target at 10.22 UT, March 10,
S=9+20dB signal
and some 120 Hertz BUZZ audio covered the channel
from 11931.9 kHz – 25 x strings on lower sideband,
16 x buzz tone strings on upper side flank up 11936.82 kHz frequency range.
Audio buzzy TONE like a lot of FENCE strings seen every 120 Hertz apart distance
each sideband though. I guess this one faulty TX unit
-- one tx of at least 9 -- nine high power SW txs available
at Riyadh bcast center in Saudi Arabia. vy73 de wolfie df5sx

Subject: Re: [HCDX] [DXplorer] [bdxc-news] Republic of Yemen Radio - 11935 kHz Possibly I am the most technically detailed. Just now 0712 via Kuwait I see a totally 28 of 120 Hz evenly spaced strings in each sideband centred on measured 11934.9 (with 10HZ error as the tune is on 4,89) In Kuwait you can hear clearly the sound with the fence heard as a square sound. The transmitting sound is good, Zacharias Liangas

2nd check a half hour later showed an accompanied low frq audio
TONE like a lot of FENCE strings seen
every 120 Hertz apart distance
each sideband though. I guess this one faulty TX unit -- of at least 9 -- nine high power SW txs available
at Riyadh bcast center in Saudi Arabia. 73 wolfie -----Ursprüngliche Nachricht-----

Noted at 1855 UTC on 9 March 2025. Presumably this is a transmitter fault rather than jamming – see Rob Wagner’s
