MTR2000 900 Low Audio

Post by n2pdq »

Just picked up a MTR2k 900, which was originally part of a smartnet trunk system. I programmed it into the ham band, as a stand along repeater.
It receives fine, however it does not have very much TX audio. only about .800Khz deviation.

I also tried to use the rear accessory connector with my allstar node, which has been working on my UHF mtr, same results. very low audio.

I did go into the service menu, and brought up the rear input level, but didn't have any effect.

Any thoughts on getting it to work?

I did try to program it into the native commercial band, still low audio.

Well that maybe the fact that the repeater is most likely narrowband only.
If you are listening to in with a receiver that is set wide, it's not gonna be real loud

Well, 0.8k deviation is not very much, even if narrow band. I just looked at a uhf mtr with low and distorted audio for a local club. The issue was found to be in the control board. replaced it, full audio.
