Hi there, I have a problem with my K1-4 on 30/40m. First I have to say that it was working before and I don't know what happened.
Here is what I know: - Power out on 15/20 is ok. - Power out on 30/40 is 0.1W, probably less - I am losing the signal between DRV (1.5Vpp) and PA (0.1Vpp). Measured with Oscilloscope. - To be precise the signal is present at the base of Q7, but is extremely weak at the collector. - I checked Relays K7 and K8 manually. They work. - I checked T4. Ok. - I have a dummy load attached. Measured 50Ohms. - I checked L4-L6. 0Ohms. - Of course I checked solder joints/bridges What else can I do or check? What could be the problem? Thanks in advance!
