Hi all

A few years ago I wrote a Python program to decode telemetry transmissions using the QRPLabs protocol. It worked fine, and derived the telemetry channel by looking at the third element of the call sign, and adding 10 if the first element was a 'Q'. That is, a max of 20 channels.

I see from the U4B page that there are now 600 channels. Is the channel still derivable from the telemetry sent, and if so, what is the algorithm, please?

Thanks

Roger
