I have a problem with the transceiver. The transmit section is not working. The rig receives and produces a sidetone. The S meter goes to full bars with a 50 micro volt input signal into the antenna. The waveforms on CLK0 and CLK1 are quadrature square waves. But there seems to be no output waveform on CLK2.
Can some one describe what the CLK2 waveform should look like ?
There is a square wave at IC3B-5 at Key down.? I hope that IC1 is not smoked. The task of replacing IC1 looks impossible.
