[Elecraft] K2 transmitter problem

Hello all. I have gotten my K2 assembled and stated aligning the filters using Spectogram and the VFO stopped working. I reworked any suspicious solder joints to no avail. I discovered with the help of a friend with a scope that the encoder had failed. I replaced the encoder and discovered I

Dan, Too much information - if the VFO is not working, then the HI CUR messages and power output are not yet relevant. First step is to see if the VFO is working and is on the correct frequency. Connect the internal counter probe to TP1. Set the K2 frequency to 7000.00 kHz and do a CAL FCTR.

I am having a problem with my transmitter testing. When I try to transmit my K2 says Hi-Cur and the power indication stays at 0.1. However the wattmeter I have attached to the antenna indicates 10 watts or more. I have the wattmeter hooked up to a dummy load. I tried connecting it to my antenna

Kieth, FB on your K2 symptoms - yes that was a good description. OK, for the explaination: The K2 detects the power output and sends it to the microprocessor on the VRFDET signal line. If the VRFDET line indicates a power level less than the power requested by the power control knob, the uP
