RE: Re: [Repeater-Builder] FLAT AUDIO -- GM300 / MAXTRAC

[Eric Lemmon]

On a GM300 radio, Pin 5 of the 16-pin accessory connector is flat audio input to the transmitter, and is either limited or unlimited, depending upon the position of jumper JU701.  Receive audio output is available at Pin 11, and is either flat and unmuted or de-emphasized and muted, depending upon the position of jumper JU551.   The MaxTrac uses the same pin assignments as the GM300, except it does not have JU701.  JU551 has the same function as in the GM300 radio.   73, Eric Lemmon WB6FLY From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of James Sent: Saturday, April 29, 2006 8:24 PM To: Repeater-Builder@yahoogroups.com Subject: [Norton AntiSpam] Re: [Repeater-Builder] FLAT AUDIO -- GM300 / MAXTRAC All Maxtrac, Radius, GM300, 1225 and CDM series radios have flat audio at pin 5.  I also believe that on most (except CDM, and 1225) there is a jumper inside to allow you to bypass the limiter as well, and bypass the 300 Hz HPF. I do not have books handy, but look at the markings on your board, they might be labeled to some extent.
