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 have no power out on any band at all. I get HIGH CURRENT every time I hit tune and only .4 watts out on the meter.
I ran a ground check on Q19 and the results are G= 96.7 K ohms, S=240.8 ohms, and D=276.2 ohms. I reworked the solder
on R20 and RFC14 with no effect. Any suggestions will be greatly appreciated.
