I use a program called Spectran ( freeware ) which will display the audio frequency of the output of the K3 I set the Frequency of the K3 to 9999.000 kc (usb) this will produce a 1kc tone to the sound card in the computer when tuned to WWV at 10 mhz
Spectran will then display the frequency of that audio tone on the screen. I then go into the K3 confg menu to REF CAL and adjust it so that the display on Spectran is as close to 1000 cycles ( 1kc ) as possible, the best I can set the K3 to is with in .27 of a cycle. it does vary between 5 mhz, 10 mhz @ 15 mhz though but not that much. that is close enough for me. also I find my self tuning in a station so there is a bit more highs to the sound which will also offset my tnx freq,.... guess I need to use the RIT more.. fwiw Ed -- View this message in context: http://elecraft.365791.n2.nabble.com/Display-frequency-calibration-tp7563715p7563722.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
