I'll get around to that.... :) >My TR7 with the rebuilt PA ran just fine for quite a while, until I erected >a new 40 meter vertical.

IIRC, I was able to achieve a condition where it would or would not oscillate depending on what it was connected to (antenna or dummy load). I don't remember the specifics, but I think that things must be just on the edge at that point. Let me know what you come up with. 73 -Jim NU0C ---------------------------------------------------------------------- Submissions: [email protected] Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost: [EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net ----------------------------------------------------------------------
