Re: K1 building problem - VFO not working

For those interested in this problem, it turned out to be one of the cap's in the LO.  
C5, C11 and C12.  I changed all three and now the LO is working correctly.  Turns out it
was oscillating, just on the wrong frequency, 7.8Mhz, which I did not see until I lifted
R5 and Q9 to unload the LO.

Thanks for the help, especially from Don, W3FPR and Elecraft for shipping me new parts,
rapidly and at no cost!
Now on to finishing the kit!
