Err, no - (at least on the K3) in "DATA A" submode, which would typically be used for soundcard data modes, the dial frequency is that of the suppressed carrier for USB (or LSB, if REV is selected), so one method would be to use the USB dial frequency (channel center minus 1500Hz) and use (only) a 1500Hz offset (on the waterfall) in the digital mode software. Only for the sub-modes ending with 'D' would it be appropriate to use the channel center frequency. Actually for FSK, the dial will show the mark frequency, so to be completely centered in the channel, you probably should offset by half of the shift (e.g. 85Hz), but I doubt you'd get cited for being 85Hz off. Anyway, to answer the original question; the channel frequencies for CW and USB are listed at: http://www.arrl.org/news/new-60-meter-privileges-now-in-effect and should be used exactly as listed there for CW and USB modes on the K3. 73, ~iain / N6ML > On 6/22/2014 5:32 PM, Bob Myers wrote: >> >> To our K3 60-Meter Operators… >> >> Can someone please give me a list of dial display frequencies used with a >> K3 for USB and CW on 60 Meters, all five Channels? >> >> I’ve seen much of the boilerplate information around talking about carrier >> vs dial frequency but some of it is conflicting. >> >> So, I was hoping an active K3 60-Meter operator using both USB and CW can >> tell me what his/her K3 dial displays for frequency when one is dead on the >> right frequency for each Channel and Mode (USB & CW). >> >> > > ______________________________________________________________ > 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 > Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
