[Elecraft] Weirdness on K2 tuning now

[Jeff McLeman]

Ok, with the help of Ron N9RC, I found the problem. Apparently, for a 
year now, pin 16 on U4 on the RF board was badly soldered. It worked 
at first, but when I was futzing with the A to B upgrade apparently I 
"jar'd" it loose. When I put the Thermistor upgrade in, it got even 
worse. Ron said look the bottom mounted resistors. So while i was 
perusing with the magnifier, pin 16 came into view.
It looked horrible. I re-flowed, and viola! The chirping went away. 
Re-ran PLL cal, yet again, and now the rig is working fine.

it is amazing how it worked this long :)

Thanks to Ron, N9RC for just the moral support an to others that have 
responded. Again, this reflector is awesome.
