Guess this qualifies me for the Old FARTS club, which another ham and I started.  Check out KC0SVS callsign.   I had a 5V in the middle 60's.  A lot of the other hams were using the newer80D's and I envied them.   Lance WN0L - a ham for 42 years.     ----- Original Message ----- From: Ted Bleiman K9MDM - MDM Radio To: Repeater-Builder@yahoogroups.com Sent: Saturday, January 08, 2005 11:07 AM Subject: Re: [Repeater-Builder] Re: Motorola microphone schematic john i thought the 5v perceded the light bulb. mdm "John J.
