What's was blocking my sound card decoding was as i read the sampling rate i was using on sprectra view with the UK fun dongle. As soon as
i put 48000hz the CW decoder start to decoded but nothing on the TLM screen yet (BPSK). I manually track the doppler shift and it not seems
to be very critical but i'm still in the dark about the BPSK data?
