RE: [Repeater-Builder] Re: Ge mastr 2 link question
I'm not so sure you have it right yet.. Now you have audio that is not processed, which will bring another wave of 100 helpers. Don't rush it to the hill. Burn it in - listen to the audio. You may need some de-emphasis now. Then the old .2 cap and 15K argument will start. You are not "golden" yet. One of my suggestions which I always give: Don't rush it to the hill. We always find time to fix it, but we never have time to do it right the first time. Sit on it for a while. Make it work. Try to break it. I have 17 radios, and have one failure every two years. Key it down - burn it in.

Re: [Repeater-Builder] Re: Ge mastr 2 link question
Mike, It's good to hear the problem is resolved, but unless you need the local monitor speaker on a regular basis, it can signifgicantly reduce current consumption on the receiver to disable the B+ supply to the audio amp, rather than run it into an audio dummy load. A set of instructions I once used for converting a Mastr II UHF mobile for full-duplex repeater operation suggested removing the audio output transformer to avoid this problem and save weight. I thought I might one day want the speaker amp functional again, so instead, I unsoldered and lifted one end of a large resistor (or two, don't remember exactly,) to interrupt power to the stage. It's been a long time since I had that manual in front of me, but it was pretty easy to do. Good luck with the weather! 73, Paul, AE4KR - Original Message - From: Mike DeWaele To: Repeater-Builder@yahoogroups.com Sent: Tuesday, October 21, 2008 8:21 PM Subject: RE: [Repeater-Builder] Re: Ge mastr 2 link question Thanks to all that replied with suggestions for my linking problem.
