[amsat-bb] FoxTelem with RTL-SDR

[EDWARD KROME]

uhh.. here is probably the worst possible answer.. I plugged it in and  it worked. Chris told me it was experimental, but it worked on 2 different RTL's, RP3B+, RP4B. All defaults. IQ. Raised cosine. 145935. automatic gain. 200 cutoff, 512 samples. I know nothing about Linux. (I'd rather be lucky than good any day.) Wish I could be of more assistance.

But the same arrangement (with HB lindenblad omni) works just fine on all the 2M sats. (well, I only get about 60% as many frames on the RTLSDR as I do on a similar setup (same omni antenna, split) with FCDP+/RP3B+.) But HuskySat works properly with SDRPlay/HDSDR/win10/1.08y/tracked yagi/tracking & doppler SatPC32. No idea why.
