Clark, You either have a non-functioning VFO, or you have something wrong with your probe (or Q9/Q10 on the Control Board). Try the probe in TP2 to see if you get a frequency displayed - if you do, you likely have a VFO problem - first place to check is T5 - make certain the leads are well stripped and tinned, you should have a bit of tinned wire on the top of the board. Examine the winding carefully, if you wound the green wire in the wrong direction, the VFO will not work. If you have the wrong number of turns, it may be off frequency enough that the PLL will not lock in. When counting toroid turns, count the number of times the wire passes through the center of the core. A straight wire through the center is one turn, a full wrap around the core is two turns.
There are a lot of "ifs" in the above statement, but take them into consideration and get back with us if you do not find the problem. 73, Don W3FPR Clark Ward Jr wrote: > I got discouraged after having more than a few issues with my K2 and > have returned to finish the project now that I'm not eyeballs-deep in > nursing school. > > I'm in 'Alignment and Test, Part II' in the VCO Test.
