Hi, I've just done BFO alignment and freq. calibration on my K2 and have some
questions. I can zero beat AM stations around 7130 kHz with +-10Hz. 1) BFO range: High freq. = 4917.13 KHz (>= 4916.3 -> ok) Low freq. = 4913.08 KHz (not <= 4912.7 !!!) Range 4.05 kHz (>= 3.6 kHz -> ok) Should I have concern about BFO low freq. is 1.1kHz too high? 2) BFO alignment: I did not found any instructions on how I should use filter crystals frequency written on the bag. It is "3.6" in my case. Nevertheless I am able to get all FL1-FL4 into desired range, using RF noise and SpectranV2 on my PC. The pitch does not change when I toggle "cw" and "cw rev." Are my BFO alignment values ok? +-------+-------+---------+-------+ |Mode |FL1 | BF1 | +-------+-------+---------+-------+ |CW norm|1,50 |bF1t103c |4913,60| |CW rev | |bF1t148c |4914,71| |LSB |2,20 |bF1t092l |4913,51| |USB | |bF1t181u |4916,00| +-------+-------+---------+-------+ +-------+-------+--------+-------+ |Mode |FL2 | BF2 | +-------+-------+--------+-------+ |CW norm|0,70 |bF2 033c|4913,22| |CW rev | |bF2 137c|4914,21| |LSB |2,00 |bF2 114l|4913,70| |USB | |bF2 171u|4915,70| +-------+-------+--------+-------+ +-------+-------+---------+-------+ |Mode |FL3 | BF3 | +-------+-------+---------+-------+ |CW norm|0,40 |bF3 021c |4913,18| |CW rev | |bF3 136c |4914,17| |LSB |1,80 |bF3 090l |4913,50| |USB | |bF3 168u |4915,59| +-------+-------+---------+-------+ +-------+-------+--------+-------+ |Mode |FL4 | BF4 | +-------+-------+--------+-------+ |CW norm|0,20 |bF4 013c|4913,14| |CW rev | |bF4 135c|4914,13| |LSB |1,60 |bF4 090l|4913,50| |USB | |bF4 161u|4915,31| +-------+-------+--------+-------+ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
