Can anyone please tell me how to adjust the master oscillator in a VX-1R?
Mine just spontaneously jumped in frequency. Now when I set the operating
frequency to 146.52 MHz, I am actually transmitting on 146.533. Similarly,
when I set the dial to 433.000 MHz, I am transmitting on 443.040 MHz. These
have been verified by a freq counter and another rig.
I have disassembled the radio, and I am staring at the main board. Beneath
the LCD display assembly I see three large square trimmer pots and one small
trimmer (capacitor, I think). Which one can I try to adjust?
