I want to fine tune the temp compensation by adjusting the resistor RA, currently at 33k and would like to confirm my thinking before starting. My K2/100 drifts down about 50Hz after 30 minutes from turn on and stabilizes. After a good period of transmitting which gets the fan on high it will drift down another 40 to 50Hz. The PLL range is 13.26kHz
The uncompensated oscillator drifts down with a temperature increase therefore I need to further increase the compensation. To achieve this I need to decrease the value of RA. Perhaps 27k or 22k? Have I got this right? 73, Nigel ZL2DF _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
