Looking for PSK31 advice
Thanks for the input guys.
I am using a Buxcomm rascal interface (I had forgotten the make, but have
been reminded since), which apparently has excellent isolation.
The problem occurs equally on all HF bands, so is not really frequency
specific.
If its a stray RF problem, which I am very willing to accept, I'm surprised
that it effects two very differently designed computers in exactly the same
way.
