[Elecraft] Help with K3S upgrades

[Mike Harris]

Agreed. I've have the external ref module which actually measures the 
TCXO frequency and on my K3 the drift is pretty close to over after 60 
minutes. I've tracked it all the way to four hours. It is useful to keep 
an eye on the front panel temp (DISP - FP). The TXCO is located in close 
order with the front panel and that influences the drift. Mine usually 
tops out at 37 to 39C.
