It's merely on the short list of things that I check when these sort
of symptoms show up. Next would be changing the output/input sound
level settings. Low/lower early in the chain.

I use direwolf. It gives a signal strength report with a received
signal. Software manual has optimal window. Also can do bit flipping
to recover unrecoverable packets. (corrupted data retrieved by
compting the checksum).

Can you record the RF on an SDR and make multiple tries decoding?

Neatest thing is that RF becomes digital. Store record forward reverse
fold spindle and mutilate.
