Sweet, second cross link signal to look into! I missed that, you got the gears turning.......
So lets see.... 145.900MHz to 146.000MHz for FO-29 passband.
A quick look through JE9PEL satlist reveals these downlinks:
AO73 tlm bcn, 145.935 MHz AO73 transponder, 145.970-145.950 MHz AO85, 145.978 MHz First-MOVE cubesat (NORAD ID 39439), 145.970MHz DUCHIFAT, 145.980 MHz QB50p1/FUNcube3 (EO-79) transponder, 145.970-145.945 MHz VELOX-I, 145.980 MHz UKube-1/FUNcube-2, 145.915 MHz DeorbitSail, 145.975 MHz CAS-3E (XW-2E) transponder, 145.935-145.915 MHz CAS-3F (XW-2F) transponder, 146.000-146.980 MHz Fox-1B, 145.960 MHz Fox-1C, 145.920 MHz
I guess its not that surprising when FO-29 has half of the 2m Satellite Service allocation for its uplink. Next thing to do is figure out which ones are the most likely to be successful based on power levels, modulation schemes, transmission rate, which ones are using Forward Error Correction, etc. And then look at the orbits for possible chain events.
fun stuff!
Does anyone know the uplink receiver sensitivity and antenna gain/design on FO-29?

Speaking of FM signals on FO-29, you'll be able to hear the AO-85 transponder through FO-29 when their paths cross as well. I wonder if you could get a high enough SNR to decode the DUV...

I wouldn't recommend playing the FM audio heard via FO-29 to a group of children. Normally it's not English. It's most likely NOT a religious broadcast based on their choice of crude words.

So yes, in the last couple weeks I've seen a LOT of FM activity on FO-29. And based on my experience with Friday's pass, which was ascending, I'm leading towards the Central/South America QRM theory. Lots of strong FM activity as the pass started and the satellite was over the lower latitudes, but as FO-29 ascended over higher latitudes towards the north pole, the FM activity died down.
