[Elecraft] K2 rx alignment problem
Greetings- I am having a problem understanding what I did wrong after I aligned the filters in my K2 using spectrogram. The basic problem is this; the indicated receive frequency for a cw signal is reading 890 to 940 hertz too low. I do not even have enough RIT to make up the difference. I have confirmed that my transmitted signal agrees with the indicated frequency on my VFO. So tx is confirmed transmiting at indicated frequency on my VFO. But for some reason the RX is way off. What is the best course of action to tighten up the rx so that the indicated rx frequency is again correct? -- -Nick NT1A __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] k2 rx alignment problem solved
Hi Guys, Well, after pondering the problem for a while, it dawned on me that MAYBE I had adjusted my filters to the wrong side of the BFO - As it turns out - I had!

Re: [Elecraft] K2 rx alignment problem
Nick, That difference is close to twice your sidetone pitch, so I would venture a guess that some of your CW filters are not on the correct sideband. Check with the K2 set to a band lower than 15 meters. For CW, the DAC values (and the frequencies) for the filter BFOs should all be lower than those for CWr. In other words, the CW filters must be less than the filter center frequency (about 4913.6 kHz) while the CWr frequencies must be higher. 73, Don W3FPR nick thomas wrote: Greetings- I am having a problem understanding what I did wrong after I aligned the filters in my K2 using spectrogram.
