Software and radio are working fine ... made a bunch of contacts and new friends yesterday! 73, Dennis - WU6X

I tried the MSWINSCK update described in the link sent by W8NSI, and when I went back and tried VarAC again ... in worked! 73, Dennis - WU6X

Thanks Jim. Well, it appears it happens with Win7 Pro, which I run here. Actually, I came back and changed my response as I tried the MSWINSCK update described in the link you sent, and when I went back and tried VarAC again ... it worked! Now, I just need to find someone listening. Hi! Thanks and 73, Dennis - WU6X
