[Elecraft] K3 60-Meter Dial Display Frequencies
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).

Re: [Elecraft] K3 60-Meter Dial Display Frequencies
Bob, You did not specify the mode, but I can answer for any mode. For SSB, take the FCC specified center frequencies, and subtract 1.5 kHz for the USB carrier frequency. For CW and narrowband data modes, the Elecraft display will be at the specified center frequencies. For SSB, the K2, K3 and KX3 display the suppressed carrier frequency, and the regulations require that the USB signal be centered on the channel - subtracting 1.5 kHz will provide that centering. For CW and soundcard data modes, Elecraft gear displays the transmit carrier frequency, and that should be the channel center. Other transceivers may handle the frequency display differently, and I can only speak for how Elecraft handles it. 73, Don W3FPR 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?

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?

Re: [Elecraft] K3 60-Meter Dial Display Frequencies
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? The following table shows which modes may be used on which frequencies: Displayed Frequency Authorized Modes (Emissions) 5330.5 kHz USB Phone (2K80J3E), USB PSK31 (60H0J2B), USB PACTOR-III (2K80J2D) 5332.0 kHz CW (150HA1A) 5346.5 kHz USB Phone (2K80J3E), USB PSK31 (60H0J2B), USB PACTOR-III (2K80J2D) 5348.0 kHz CW (150HA1A) 5357.0 kHz USB Phone (2K80J3E), USB PSK31 (60H0J2B), USB PACTOR-III (2K80J2D) 5358.5 kHz CW (150HA1A) 5371.5 kHz USB Phone (2K80J3E), USB PSK31 (60H0J2B), USB PACTOR-III (2K80J2D) 5373.0 kHz CW (150HA1A) 5403.5 kHz USB Phone (2K80J3E), USB PSK31 (60H0J2B), USB PACTOR-III (2K80J2D) 5405.0 kHz CW (150HA1A) I store these ten frequencies shown above in ten memories on my various HF rigs, in pairs of two with USB mode stored for the first and CW mode stored for the second of each pair. Background: The FCC report related to the 05 March 2012 60 meter band rule changes was published in the Federal Register at http://www.gpo.gov/fdsys/pkg/FR-2012-02-03/pdf/2012-2477.pdf . It authorizes five 3 kHz channels, each with the following channel CENTER frequencies: 5332.0 kHz 5348.0 kHz 5358.5 kHz 5373.0 kHz 5405.0 kHz . It designates five channel CARRIER frequencies that are 1.5 kHz BELOW the channel CENTER frequencies: 5330.5 kHz 5346.5 kHz 5357.0 kHz 5371.5 kHz 5403.5 kHz . The authorized emissions and frequencies for 60 meters are: 150HA1A CW Morse telegraphy. Transmitter dial must be set to the channel CENTER frequency. 2K80J3E USB phone. Transmitter dial must be set to the channel CARRIER frequency (which is 1.5 kHz BELOW the channel CENTER frequency). 60H0J2B RTTY (ONLY PSK31, sent on USB phone). Transmitter dial must be set to the channel CARRIER frequency (which is 1.5 kHz BELOW the channel CENTER frequency). 2K80J2D DATA (ONLY PACTOR-III, sent on USB phone). Transmitter dial must be set to the channel CARRIER frequency (which is 1.5 kHz BELOW the channel CENTER frequency). The applicable 47CFR97 regulations are found at http://www.ecfr.gov/cgi-bin/text-idx?c=ecfrSID=1e17c74c2975ff111a839967ad3f2f38rgn=div5view=textnode=47:5.0.1.1.6idno=47#47:5.0.1.1.6.4.157.2 Most related information is found in sections 97.303 though 97.307 found in the above link.

Re: [Elecraft] K3 60-Meter Dial Display Frequencies
Ian is correct - yes, I was thinking of DATA modes PSK D and FSK D. The general answer is to know your transceiver and how it displays the transmit frequency. 73, Don W3FPR On 6/22/2014 6:10 PM, iain macdonnell - N6ML wrote: On Sun, Jun 22, 2014 at 2:43 PM, Don Wilhelm w3...@embarqmail.com wrote: You did not specify the mode, but I can answer for any mode.
