[Elecraft] Kx3 Px3 Temperature Compensation

[Doug Millar]

It took two tries, but finally got traces and frequency stability good enough on my Kx3 for JT mode on 2 meters, using the internal 2m transverter. TX/RX recovery at 2w output showed minimal frequency change for a few seconds.I used the Px3 to evaluate the frequency of the signal generator over time. (Spectra view or other SDR from the radio would also work.) I also used an audio frequency counter to monitor the stability of the cw note. I think it took two runs because by the second time, I was familiar with what the radio would do and was familiar with the functions. Anyway second time was the charm. 
   I have photos of the Px3 from the first and second run. quite a difference. The radio went from unusable for that mode to very usable. Contact me off list if you want to see them. Doug K6JEY (drzarkof56 at yahoo.com)
