Putting this one in the Welcome area, as it really doesn't fit in the others... I
I have notice that it seems that as Funcube-1 comes out of eclipse, the beacon *rises* in frequency (while it is on *approach* to me)
I discovered this, as I actually adjust for doppler, but I saw it actually go *up* my waterfall display, at what seemed to be quite a rate. I had a BPf of +/-1500Hz, but had to double that, just to keep it in the pass band! I fear that it's actually changing quickly enough during that timeframe, that the Linux decoder is having issues, as even when I increased the bandwidth of the filter to compensate, I don't tend to get very many decodes on an eclipse -> daylight pass, even post the beacon going full power (which is very obvious...)
I'm guessing it's temperature related, and I don't expect anyone to fix the Linux decoder (I can go fiddle and adjust filter B/W's and offsets etc), but can anyone confirm the behaviour I see ? Has anyone characterised it, and worked out what the extra frequency shift is precisely ?
