As has been mentioned several times recently, audio spectrum analysis software can be very useful for aligning the filters in a K2 and for lots of other purposes as well. "Spectrogram" is frequently mentioned as a good program for Windows.
For those of us who run some variant of GNU Linux, the "Baudline" program (available as a free download at http://www.baudline.com) provides much the same functionality. I've been using it for several months now and find it fast, very powerful, and easy to use once you get the hang of the somewhat different user interface (you WILL have to read the manual.) The manual is well written and easy to understand if you have some familiarity with sampling and basic signal analysis concepts. 73 -- Joe KB8AP ______________________________________________________________ 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
