Dave, Go to my website www.w3fpr.com, and look at the article dealing with K2 Dial Calibration - it includes the filter setting, but you may as well do the whole thing and have good dial calibration as well. Spectrogram is available for download at Tom Hammond's website www.n0ss.net, and Tom has some nice documentation with setup information and screenshots.
You can expect as much as 20 Hz variation in pitch as you change from filter to filter since it is limited by the DAC resolution. That is not enough variation to be troublesome, but is disconcerting the first time you hear it. If you have more than 20 Hz, the BFOs are not set up right. I hope you are not iced in there today, we have a nice slick sheet here in Wake Forest. 73, Don W3FPR On 1/11/2011 2:34 PM, Dave Anderson, K4SV wrote: > Hi All, > > Just completed assembling my K2 kit I had on the shelf for 7 years SN 3089. > > After engineering a cap change to get the VCO voltage correct (C72 from 270 to > 300pf) it appears to work now. > > I went through the tuning OK but wanted to ask if there is a better way to > adjust the BFO so that all of the filters peak on the same frequency?
