The last PR has caused problems with reception

[righthalfplane]

The last PR has caused problems with reception. With Previous versions readStream returned the data and never returned a zero. It worked Ok on Bullseye and DragonOS. Now, readStream returns a zero every few reads and it loses the data and the audio is choppy. One other strange thing is it normal comes up at a very low reception gain and you have to turn the AGC on and off the get the full amplitude output.
