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).

Thanks,

Bob W1XT

Re: 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,

Actually he specified "USB and CW" (twice)

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.

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=ecfr&SID=1e17c74c2975ff111a839967ad3f2f38&rgn=div5&view=text&node=47:5.0.1.1.6&idno=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.

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.
