[Elecraft] KX3 OSC Temp And Freq Drift Relationship?

[Jack Chomley]

Tonight I have been experimenting on PSK31 at 3 watts and 5 watts. In my shack the OSC Temp is about 38 deg and transmitting my CQ call about every 60 seconds @ 3 watts takes the OSC Temp to 39 deg, on RX it drops back to 38 deg.
At 5 watts it goes up to 41 deg, but immediately settles back to 38 deg.
My question is, what would the estimated frequency change be, per degree of OSC Temp change? I am trying to work out the total freq shift between the start and the end of my PSK31 transmission.
Now, I have not done the OSC temp compensation routine to my radio. Trying not to go down this road in case I make a hash of it :-)
In closing, I will not be using WSPR or JT65 etc with this radio.
