Just a warning. That article is out of date, and hence inaccurate. With current firmware it is not necessary to run CAL PLL on every band, just on 40 meters. It's pretty hard to "zero beat" WWV in USB/LSB, since the AM carrier will become inaudible when you're anywhere close. The lower range of human hearing and bandwidth limitations get in the way. This is what works for me: I find that tuning while bouncing between USB and LSB (hold CW REV to do so without having to cycle through the other modes) and matching the sound of the WWV marker tones works FB. When the tones match, you're on frequency (at least within ~20 Hz, the VFO+BFO cumulative error). Wayne introduced a method which might work quicker for actually setting C22 ( http://www.qsl.net/w3fpr/n6kr_method.htm ): If you're tuned to 10 MHz WWV, set C22 so the difference between the VFO (TP1) and the BFO (TP2) is 10 MHz, run CAL PLL then CAL FIL, and you're done. In my experience, you actually want the VFO set about 10 Hz lower than theoretical. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
