    I am trying to troubleshoot the receiver (transmitter works perfect) on a new to me X108. The radio is very low S/N, 0069 and the board layout is different from what is published. The ADE-1 is not near the speaker, it is on the edge of the board. See picture. I suspect the problem is near the mixer IC but hard to troubleshoot with out a good board layout. Anyone have an early board layout?

    Hi! The same with mine one. I am still waiting an answer from another opinion. I try to find an old version of firmware also. The battery, I found empty, still waiting for delivery a new one. I think the cause in my transceiver is the firmware. All happened after update. Still waiting for opinions...
