Jumps per se are not a problem. I.e., if you're off frequency, the sooner you correct it the better; there's no need to tune back gradually. The error correcting code I'm using is pretty strong but it does have its limits, and being significantly off frequency can take out a lot of the information it needs to function.
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?
