I've been playing around with the filter setup in my K2 S/N 4429 to get them to my liking.
Has anyone had any luck getting the difference in pitch between CW and CW reverse to a reasonable level. I'd really like it to be within 10Hz if possible. >From my understanding the factor which determines this is the accuracy which the original signal has been tuned in. I am confident in my ability to zero beat a received signal against the spot tone, which should make the tones of the two within 5Hz of each other(based on the 10Hz resolution of the VFO). But even when a signal is zero beat it seems my tone pitch between CW and CW reverse in the filters is closer to 30Hz. I've noticed that there is some discrepancy in the requested sidetone pitch in the menu setting and the actual spot tone frequency. I'm not sure if this has anything to do with it or not. I get an actual 600Hz tone when the sidetone is set for 590Hz. Measurements made with Spectrogram. Anyone have any insight, or is this small of a pitch difference between CW and CW reverse not possible due to DAC resolution maybe? -Ben KB1AHR K2 S/N 4429 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
