SAUDI ARABIA Republic of Yemen Radio {in excile via Riyadh or Jeddah
bcast centers in Saudi Arabia,ed.} on 11935kHz (or more precisely 11934.79
kHz as measured on online KiwiSDR's) is once again accompanied by a buzz-
ing noise. Noted at 1855 UT on 9 March 2025.
Presumably this is a transmitter fault rather than jamming -

SAUDI ARABIA 11934.893+ kHz, March 11 at 2037 UT, Rep. of Yemen Radio,
Arabic, still with heavy buzz. Ed Sylvester explains on the WOR iog:
"I live in Riyadh and have had meetings with SBA. At that time (early
2024), they were on the fence as to whether to continue.
The transmitters / antennas are currently in a sector of Riyadh that has
been designated for future housing projects. Hence, the government will
either fund a move or have them shut down permanently.
Because there has not been funding to date, they are cannibalizing older
transmitters for replacement parts to at least keep Yemen radio on the air
Saudi Arabia is in the midst of full bore modernization in all sectors and
DAB+ has been touted as the new medium for widespread broadcasting. They
also rely on high-powered MW broadcasters that can be heard throughout the
region.
The future of SW b'casting seems bleak in KSA as surveys of listenership
have been spotty and unconvincing. Will know more in the coming months.
Fingers crossed. 73, Ed 7Z1ES"

Re: Republic of Yemen Radio - 11935 kHz.
Curious, because WRTH says the power in Saudi Arabia and Yemen is 50 Hz.
So we should expect the faulty transmitter to show "fence pickets" every
100 Hertz, not every 120 Hertz.
Makes me wonder if these transmissions might be coming from a U.S. mili-
tary base in Saudi Arabia.
