SAUDI ARABIA 11934.894 kHz measured remotedly on Perseus SDR unit
in Doha Qatar ME target at 12.50 UT, Monday March 11,
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.

Thanks to Tony for the tip.
Being heard in Lytchett Matravers, near Poole, at 1913 today with the

Republic of Yemen Radio on 11935 kHz (or more precisely 11934.79 kHz as
measured on online KiwiSDR’s) is once again accompanied by a buzzing noise.
Noted at 1855 UTC on 9 March 2025.
Presumably this is a transmitter fault rather than jamming – see Rob Wagner’s
