Thanks to Tony for the tip. Being heard in Lytchett Matravers, near Poole, at 1913 today with the
buzzing noise over a talk from a YL.

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
