I mentioned that I have the audio amp disabled. I do this by sliding a piece of Teflon tubing down over the pin that supplies power to the audio amp. It is easy enough to pull the tubing back off and use the amp for desense testing by doing it this way.
I think I picked up this method for disabling the audio amp here on the Repeater Builder list - or might have been the GE Mastr II list. 73 - Jim W5ZIT --- On Fri, 9/12/08, Gerald Pelnar <[EMAIL PROTECTED]> wrote: From: Gerald Pelnar <[EMAIL PROTECTED]> Subject: Re: [Repeater-Builder] NHRC-3/M2 Processor Noise To: [email protected] Date: Friday, September 12, 2008, 6:35 PM If there is not a speaker or load attached to the speaker leads, it will make funny noises in the audio.
