[Elecraft] PLL temperature compensated drift mod a winner

[Tom Whiteside]

Thanks for another great mod!   While I've never had any complaints about
drift in my K2, with the KPA100 installed it does experience a bigger
temperature change and I want my K2 to "be all that it can be" so installed
this new mod.    The documentation includes an optional test that involves
testing the K2/100 after a 30 minute warmup (1W in 20M band) and then
repeating this test after running keydown at 20 Watts 30 minutes to really
heat things up.    For a reference, I used a fully warmed up FT1000D.
Before the mod, the K2 moved by 120 Hz with this test and just 2 Hz after
the mod.   An amazing improvement!    Now to get some time to assemble the
KDSP2!
