Galaxy Saturn - probs with TX power

I get the radio now from a 4 years ago died friend from his wife now. The radio was not used for these 4 years. I wanted now to use it, but I had to find out, that it is sending only stable with maximum of 0,5 Watts On "A band" with 0,1 Watts ... to "E band" maximum 3 Watts but in "E" then the TX is blocked. I have to switch it off and on again, or go back to "A" and push the TX for a short moment. I can TX on A to D for longer time. Only on E it blocks. I have also an external watt-meter it displays the too low signal power too. First I thinked that the amp is broken, so I have change the 2166 transistor - but nothing changed  What can I do to repair / fix it? The mystery is: that I can not TX on "E band" for longer then 1 or 2 seconds - then the radio blocks the TXing. Then there is no reaction when pushing the mike button. I must switch off and on, then I can TX again. But in the other band (A to D) only with 1/10 of the normal power the radio must have. When turning the power knob, the output power changes, so the potentiometer looks ok I mad sure that the fault is not my antenna, because with other CBs I can TX and RX very good! Also the problem apears with a dummy I have the schematic/manual here - If some one has use for it and it is legal, I can post a link to it. Possible also needed to help me Please help me! I THANK YOU !!!  73, Andy -- Speedmaster Post the link to your schematic... |
