Could 14295kHz be a harmonic from 4765 kHz on which Radio Progress broadcast around this time?
Yes, that is a possible answer for the station on 14295.0 kHz, although I have never copied both stations at the same time well enough to confirm the same audio. But, 4765 is a tad over 9 Hz high, and 14295 is about 29 Hz high, 3 times the frequency offset, that would strongly suggest the third harmonic.
That still leave the 14295.16 station, and I have not found anything that might be placing that as a harmonic.
T!
(edit) Ding Ding Ding, we have a winner. Good call Oliver. Both stations were never strong enough at the same time tonight for me to compare the audio, however both went off the air at the exact same time at 0402:08z.
That is quite the harmonic there.
