John, I did a search on the email archives and found what you are looking for: http://mailman.qth.net/pipermail/kenwood/2003-May/007960.html Larry K7YBZ -----Original Message----- From: kenwood-bounces at mailman.qth.net [mailto:kenwood-bounces at mailman.qth.net] On Behalf Of John Sent: Sunday, November 29, 2009 2:02 AM To: Kenwood at Mailman.qth.net Subject: [Kenwood] Odd fault Hi all I submitted this a few days ago but had no response and resending it in case it was missed by some readers A few years ago I read on the forum a case of the microphone earth return being burnt out on the I.F.pcb board of a Kenwood TS850 and it was thought to have been caused by current being passed into the microphone's negative then to earth by the metal shroud on the microphone plug, when the microphone was plugged into the rig. My brother's rig has this fault. Can anyone remember the cause of this occurring? Many thanks John G3oic ______________________________________________________________ Kenwood mailing list Home: http://mailman.qth.net/mailman/listinfo/kenwood Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Kenwood at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
