"Howard Traxler" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- I have the same problem with my TR-4; but only I think it's the band pass shift that's moving because the background noise gets a much higher pitch. A firm slap on the top of the case brings it back to normal.

It has nice audio and good : output on all bands, but suffers from what I think is a dirty relay : (scratchy intermittent noise, corrected temporarily by switching : briefly to transmit) -- but a greater annoyance is apparent VFO : jumping on both transmit and receive - by a few hundred Hz. This : happens even if the rig is well warmed up. : : The AC-4 that powers it is old and will need to be upgraded - probably : with the heathkitshop board. I did notice that the bias, after being : set a week ago, had dropped by about 15-20% and had to be reset. : : Searching the Drakelist didn't point me in any direction so I thought : I'd just ask if there is perhaps a common cause/cure for the frequency : jumps. : : Thanks es 73, : : Mitch Chesler NB2N : : : : ---------------------------------------------------------------------- : 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 : ---------------------------------------------------------------------- : : : -- : No virus found in this incoming message. : Checked by AVG Free Edition. : Version: 7.5.516 / Virus Database: 269.19.1/1220 - Release Date: 1/11/2008 6:09 PM : : ---------------------------------------------------------------------- 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 ----------------------------------------------------------------------
