MTR2000 modulation error.

Post by dkjbl »

Hi
My MTR2000 based 2M repeater has lost its modulation; the transmitter has normal output power but no modulation with AF signal on the wire line interface or from the service mic. The receiver is working ok.
The station is passing self-test.
Any suggestions to where to start looking for the error, or to where I can find a schematics/service manual?
Best regards
Jorgen/OZ1ETE

Does it generate PL?

I've never seen a full service manual for the MTR.

Jorgen,

On your 2 Meter Power Amp, could you send me the 4 digit series of the tuning Data alpha numeric numbers, I have a PA will no data?

Did you get your audio problem solved?


Thanks,
