Hi, All,
I discovered a 'feature' of using the XVRX port that I at first thought
was a software-signal-routing 'bug', which it is not.
My station is VHF and up only, and is very heavily

audio being used, all in the name of
Hello Roger,
I have only a single Elecraft XV144 xvtr here, but I don't see any of
