The AFC option in many of the digital software programs will cause the frequency to change. I use DM780 and if I have the AFC option enabled, it will cause my frequency to shift. In noisy band conditions it is very noticeable. Its as if the AFC is chasing the static crashes.
If both stations have that software option enabled, then its very likely that it has nothing to do with your rigs frequency stability. Its actually the software causing the frequency to change. Take a look at that the next time you find yourself chasing a station up or down the band during a PSK contact. 73 de W9MO Bob Young -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-KTCXO3-1-and-standard-TXCO-drift-rates-tp7441550p7445782.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
