Re: [Repeater-Builder] 19D424089G1
I believe you are talking about an Exec II. Several places to check before replacing the PA. A common problem is the jumper between the exciter and the PA. The RCA connectors sometimes go intermittent. Also, if the TR relay hasn't been jumpered, it could have gone intermittent.

We have reason to suspect the PA in our repeater. It has developed various intermittent behaviors (dropping carrier, distorted audio, varying output, etc.) .. I believe this to be the 60 watt PA for the GE Mastr II Exec II mobile radio conversion. If I have the wrong board number, please advise ...

Larry - This is either an Exec II or a Mastr II - two different radios. The Exec II mobile is 'gray' and has a plastic, non-movable handle. The Mastr II mobile has a foldable handle. Which one do you have?

RE: [Repeater-Builder] 19D424089G1
Larry, You have it right- the 19D424089G1 PA is rated at 60 watts over the 132-174 MHz band, with an external relay, and is found in the Mastr Executive II radio. LBI-30253 covers it: www.repeater-builder.com/ge/lbi-library/lbi-30352c.pdf The symptoms you describe may also be caused by a problem in the exciter, the relay, or the system control board. Have you already discounted these possible culprits? 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Larry Wagoner Sent: Monday, September 06, 2010 5:27 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] 19D424089G1 Anyone have one of the above they wish to part with?

Have you already discounted these possible culprits? Nothing eliminated yet. This radio was doing OK - and developed this problem lately. We have noticed variable output, garbling of the audio, and what appears to me from a remote mobile location to be momentary carrier drops. The garbled audio is accompanied by a major drop in output, while the momentary carrier drops look almost like someone is letting go of the key were we working simplex. It lasts only a moment before coming back up. Larry Wagoner - N5WLW PRCARC Training Officer PIC - MS SECT ARRL
