Just listened to RS30 for the first time on 435.315 ish
There's an interesting data mode that follows the short periods of CW
telemetry. It appears to comprise of data being transmitted at 4800 bps in some
form of 'packet' at around 4 times a second.
I'm not good with data modes but that's an assumption based on a
transmission which has a carrier in the center with peaks of energy at plus and minus
2400 Hz but with the whole 4800 bandwidth occupied. Does that sound right?

As the signal is transmitted you can count another 'rate' which works out at
Too wide for my radio on SSB. If it's a picture, I wonder how it's
There's an overhead pass in Europe with AOS at 17.09 and LOS at 17.32.
Will try FM next time.
