Hi Guy, Yeah I bought the TCXO3 option with my kit. I've just been tracking the drift over the last day or so just out of curiosity to see how stable it is which is why I asked. I left my window open last night and my room cooled about 10 to 15 degs overnight. Sure enough, the osc. seemed to go low about 5hz. After 1/2 hour it had drifted back up about 2 or 3 hz.
Indeed astounding stability, tho how useful it actually is I don't really know. I don't think even the digital modes care about variations that small. My K2 probably drifts about 20 to 30hz from start to warmup and even then it settles down in 15-20 mins. After that it's a rock compared to what I'm used to from the old days (where you get that kind of drift during the CQ DX alone hi hi). I haven't entered my temp correction data since it's not enabled in the FW yet. I'm keeping my sheet tho of course. It'd be neat to see how much more stable it'll be once that is implemented. 73, LS W5QD -- View this message in context: http://n2.nabble.com/K3-dumb-Q-about-PPM-less-dumb-one-about-NB-tp4837301p4838354.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
