During the initial TX alignment of my K2, I can't seem to get the output power above 0.2W - it fluctuates between 0.1 and 0.2 and doesn't change as I adjust L1 and L2. I am, however, able to tune L1 and L2 for RX just fine. I am showing 350 mV at my dummy load so some RF seems to be getting through.
I don't see any obvious soldering problems and T1 through T4 appear to be wound correctly. I have not done any signal tracing yet but initial voltage check of the driver and finals appear fine. However, I am concerned about the voltage of the drivers collector. It jumps up to 14V at transmit but it's supposed to be 13.3V. I have to go out and buy a new DMM so I can do signal tracing (my cheap DMM has fixed probes and I can't adapt them properly). Any other ideas before I dive into signal tracing?
