OK that is a different issue to that which I think many folks understood from your original comment. I don't find zero beating WWV to be a problem when trimming up the TCXO calibration, the wow, wow wow is easy to detect and fine tune. Indeed, it is a regular requirement, not a do once and fo

Mike, Only when calibrating the K3 freq I tune within one Hz. Performing the Ref-Cal. That's all. 73 Arie PA3A Mike Harris schreef op 5-10-2014 13:49: Any particular reason to need to zero beat to 1Hz? I find the auto tune function works perfectly well. In fact if I'm one of many statio

Ted, Is the value you have set in PITCH the same as the audio frequency you are listening at? If so, the SPOT feature should be quite accurate. Actually, between the CWT indicator and the Auto-Spot feature of the K3, it is easy to get within a Hz or two. Auto-Spot may not work well in very c

HI, In a pileup, I ALWAYS move off zero beat, so if I transmit, I don't cover the DX station in the event I transmit on top of him/her. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopple

Any particular reason to need to zero beat to 1Hz? I find the auto tune function works perfectly well. In fact if I'm one of many stations calling I often offset 40-50Hz so as to be different from the all zero beat mush. Regards, Mike VP8NO On 05/10/2014 07:55, Arie Kleingeld PA3A wrote:

Hello Ted, When I need to be on zero beat within one Hz, I always switch on the spot on the K3 and set the received signal to the same volume. Once I hear the combination of both increase and decrease slowly, I know that I am within a Hz. It's also the way I calibrate the K3 against a standar

I have never been convinced of being accurate on zero-beat on my K3. With previous radio units, I would zero-beat by matching the tone of the received station with my own keying side-tone. But it does not seem accurate on the K3. So the question: How would I determine that my offset and side ton
