Need help to order a MTR2000 service manual that have the schematic diagram of the receiver unit, Got this unit from Ebay, Hook up the unit on my bench with a dummy load on the TX out, and apply signal on the RX input with a IFR1200, The squelch open at 0.12 micro-volt at 0.15 uv its 12 DB Sinad, when signal was increased to about 1.0 micro-volts or higher the receiver drop out, as if the agc is overloaded that cut out completely and also drop the TX, Have anyone ever experience this problem before, This is the first time I have seen this kind of problem , and its hard to fix it w/o a diagram. any help is highly appreciated.
