Rick;
Thanks for your response.
I tried to contact you on what I thought was your e-mail address but here
will be just as good.
I wonder if you would mind working with me to get this Digital thing set
up.
I need it for Air Force MARS on PACTOR HF frequencies. I also talked to a
MARS member this morning and he mentioned using FSK also but of course
the Kenwood Manual doesn't say enough about hooking it up.
Looking forward to hearing from you.
