K2 - Alignment - VCO Time…

I’ve got K. to serial number 246 on the bench and the tuning doesn’t sound exactly right, so I’m going through the basic alignment steps. Hopefully if I get the VCO set up correctly, I’ll have a good output on all the bands. Then, when I get to the BFO and filter set up, the tuning may sound like it should. Thanks for hanging in there through all this . 73, Bruce As a follow-up. I did go back to lower the initial voltage on the left side of R30 from 6.00 volts to 5.681 volts. That resulted in all of the VCO voltages across all the bands being in the range of 2.17 volts to 7.22 volts. That is within the specified range of 1.5 to 7.5 volts - PASS! #elecraft #k2 #hamradio #qrp #alignment
