Re: [Elecraft] What does the frequency readout mean?
Pete, When receiving in CW-USB and you tune to a lower pitch, you will be tuning to a higher frequency. If the receiving station is also using CW-USB, the pitch in his receiver will go up. I just verified that on the test bench. 73, Don W3FPR On 2/20/2013 7:55 AM, Pete Smith N4ZR wrote: I'm sorry I misled everyone with my mistake, writing "RIT".

It's been many decades since the sideband used for CW switched with the USB /LSB convention (above and below roughly 9 MHz) with most mainstream rigs. The sideband used for CW is constant across all bands in the K3 and also in Kenwood rigs. Unfortunately, those conventions differ. I prefer to listen to CW using what would be called USB mode on sideband. On the Kenwood TS-940 and TS-950SDX, that corresponds to their "CW" mode. On the K-3, however, that's "CW REV" -- a difference that drives me bananas when I have the K-3 as Radio 1 and my Kenwood as Radio 2, because my general purpose logging program requires both Radio 1 and Radio 2 to be the same! That said, however, suppose your K-3 is in CW REV mode, which tunes the same way as USB would. That is, as you tune from the bottom of the band up higher in frequency, and assuming you have your filter passbands centered normally, you will hear stations come into the filter passband with DESCENDING pitch. They will exit your received passband with a LOWER pitch than when they entered as you tune UP in frequency. So now let's look at the question you asked in your other posting: "Same setup, but listening to a signal on the air. "Beat note" is ~500 Hz. I turn the main tuning knob so that the received signal is lower frequency - say 200 Hz. I transmit. What does the station on the other end hear, assuming he is also using USB-CW? Does my "beat note" go up in his receiver, or down?" When you "turn the main tuning knob so that the received signal is lower frequency", you are tuning UP in frequency if you are in USB or (in the case of the K-3) CW REV mode. What the station on the other end hears, however, depends on his rig and which mode HE is using to listen to you with. If he, too, is using USB mode (or a K-3 in the CW REV mode), he will hear you get HIGHER in pitch. If not, he'll hear you get LOWER in pitch. It's been my general (statistical) impression, listening to DXpedition operators over the years, that if the operator appears to be tuning UP the band in small increments he's most likely to be listening in USB (or K-3 CW REV) mode, since many of us cut our teeth on that technique when we were neophytes. I, for one, much prefer to listen to another station's pitch sliding DOWN in frequency as I tune higher in the band. Thus, I use CW REV in the K-3, and I tune from the bottom up. So, short answer to your question: It depends.

Re: [Elecraft] What does the frequency readout mean?
One of the "features" of using LSB convention for receiving CW is that when you tune the dial to a lower frequency the pitch of the received audio gets lower. In fact, that was the old timer's test back in the day of non-single-signal receivers... if you tuned to a lower frequency and the pitch got lower, you were on the lower sideband side of the carrier.

Re: [Elecraft] What does the frequency readout mean?
Hi Rich - a very lucid reply, and you apparently understood what I was saying, despite my "RIT" mis-statement. For some reason, I was operating under the mistaken impression that the sideband used for CW followed the sideband convention for SSB. I went straight to the Cady book, unfortunately - had I referred to page 30 of the regular manual, I would have seen that normal for the K3 in CW is lower sideband on all bands. I wonder if this is generally true of modern transceivers - seems to me as if my TS-930 and Mark 5 - both now gone - switched CW sidebands as I described above.

If you change the pitch setting to 300 Hz, the K3 adjusts its suppressed carrier frequency to 3507.5 kHz so that the transmitted frequency stays on 3507.2 kHz. If you were using CW-R on upper sideband, the suppressed carrier would be at 3506.7 kHz with 500 Hz pitch, and on 3506.9 kHz with 300 Hz pitch. RIT has no effect on what the other station hears. However, if you use both RIT and XIT together, it will have an effect - exactly the same effect as if you rotated the tuning knob to produce the same tone in the receiver and the same frequency display in the VFO A display. If you are using the K3's normal CW mode, you tune "zero beat" to a station (i.e. so that what you hear is the same as your sidetone), and then you tune your VFO lower in frequency, the receiver's carrier frequency moves lower and gets closer to the signal you are receiving, so the pitch you hear goes down. If you now transmit with that lower VFO frequency, your signal will be lower in frequency than it would have been on zero beat, and therefore lower in frequency than the other station's signal. If the other station is also a K3 using lower sideband for CW, he will hear your pitch go up, because your signal is farther away from his suppressed carrier frequency. On the other hand, if the other station is using upper sideband for CW he will hear your pitch go lower. In general, if you are both using the same sideband, then when you move your main VFO (or RIT-XIT together) to change the pitch you hear, that will make the pitch the other station hears change in the opposite sense. If you are using opposite sidebands, what you both hear will change together. Since it is in general impossible to predict which sideband the other station is using for CW, it is likewise impossible to predict with certainty what he would hear if you were to adjust your transmit frequency slightly. 73, Rich VE3KI __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

There have been some good answers for you. (I saved some to help
others.)
My answer(s) is to the way I read your question(s).
The 'pitch' is the tone you will hear in your earphones, or
speaker, on both receive and transmit (cw sidetone). It is nicely
done in the K3.
BTW, the 'monitor' knob adjusts the cw sidetone level as I recall.
I haven't changed it in a couple years.
Assuming you are in CW mode:
--First, you have selected the 'pitch' that you like to hear.
--You have 'CWT' on.
--You tune a CW signal near enough to see a bar appear on the
'CWT' scale.
--Press 'spot' and the radio automatically tunes the station in to
your selected tone.
--The signal will also be centered in the filter, and centered on
the indicator.
Once you get used to the tone you have selected, you will be able
to tune well to that tone without using 'spot', or without looking
at the display if you are rushed.
However, the CWT indicator is your guide.
And finally, you said,
"I turn the RIT so that the received signal is
lower frequency - say 200 Hz. I transmit. What does the station
on the
other end hear, assuming he is also using USB-CW? Does my "beat
note" go up

As others have said, the RIT does nothing to your transmit. But
it does change your receive frequency, so that it changes the tone
you hear. Not to be confused with the 'pitch' control. The
'pitch' control only selects the pitch you like to hear when the
signal is centered in your filter. From then on, you want to tune
the receiver to a tone of that pitch, or let the radio do it
automatically for you.
As for what the station on the other end hears, that is up to that
operator, who will tune to one side of your carrier until he/she
hears a tone that is suitable.
If you are working a station with a radio that drifts in
frequency, you will often need to make a correction to the tone
you hear by using your RIT. That is it's function.
It was a good question. I think you will enjoy it as you
understand the workings.

Hi Pete:
The K3 reads the actual transmit carrier frequency. That's the
suppressed
carrier frequency in SSB and the actual carrier frequency in any
mode such
as CW in which the carrier is transmitted.
Changing the pitch has *nothing* to do with this. It will be the
same in any
case (the K3 adjusts its internal oscillators as needed to give
you the
desired audio tone without changing the carrier frequency).
To be certain, I turned on my frequency counter and checked the

RIT means *RECEIVE* Incremental Tuning. It has nothing to do

Re: [Elecraft] What does the frequency readout mean?
Hi Pete, In CW mode, the K3 reads the actual transmitted frequency. Since normal CW uses lower sideband on the K3, this means that on 3507.2 in normal CW mode, with the pitch set at 500 Hz the suppressed carrier frequency is 3507.7 kHz (500 Hz above the signal frequency). If you change the pitch setting to 300 Hz, the K3 adjusts its suppressed carrier frequency to 3507.5 kHz so that the transmitted frequency stays on 3507.2 kHz. If you were using CW-R on upper sideband, the suppressed carrier would be at 3506.7 kHz with 500 Hz pitch, and on 3506.9 kHz with 300 Hz pitch. RIT has no effect on what the other station hears. However, if you use both RIT and XIT together, it will have an effect - exactly the same effect as if you rotated the tuning knob to produce the same tone in the receiver and the same frequency display in the VFO A display. If you are using the K3's normal CW mode, you tune "zero beat" to a station (i.e. so that what you hear is the same as your sidetone), and then you tune your VFO lower in frequency, the receiver's carrier frequency moves lower and gets closer to the signal you are receiving, so the pitch you hear goes down. If you now transmit with that lower VFO frequency, your signal will be lower in frequency than it would have been on zero beat, and therefore lower in frequency than the other station's signal. If the other station is also a K3 using lower sideband for CW, he will hear your pitch go up, because your signal is farther away from his suppressed carrier frequency. On the other hand, if the other station is using upper sideband for CW he will hear your pitch go lower. In general, if you are both using the same sideband, then when you move your main VFO (or RIT-XIT together) to change the pitch you hear, that will make the pitch the other station hears change in the opposite sense. If you are using opposite sidebands, what you both hear will change together. Since it is in general impossible to predict which sideband the other station is using for CW, it is likewise impossible to predict with certainty what he would hear if you were to adjust your transmit frequency slightly. 73, Rich VE3KI __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] What does the frequency readout mean?
Pete. All Elecraft radios that I know about display the transmitted carrier frequency in CW and the suppressed carrier frequency in SSB mode. Your sidetone pitch setting is related to properly tuning a CW signal and knowing its frequency. If you tune the received signal to a pitch the same as your Sidetone pitch (that is zero-beat with the station), you will transmit on the same frequency as the station you are receiving (with RIT and XIT turned off). Turning RIT on will not move your transmit frequency, but will change your receive frequency. Turning XIT on will not alter the receive frequency, but will change the transmit frequency. I think of RIT or XIT as a 'mini split'. To add a bit more to the mental girations, the receive frequency displayed IS changed with RIT, so in order to determine your transmit frequency, you have to add or subtract the RIT offset (or just turn RIT off and you will see the transmit frequency in the display). With RIT on, what the display is telling you (assuming you used RIT to tune the station to zero beat) is the carrier frequency of the received signal. Simply changing the sidetone pitch setting without tuning the received signal to that pitch will accomplish nothing useful IMHO. 73, Don W3FPR On 2/19/2013 4:35 PM, Pete Smith N4ZR wrote: I'm having a hard time getting my head around this.

The suppressed-carrier frequency plus the CW pitch? Does that mean that when I change the pitch, the radio is actually moving its frequency a little bit? A somewhat related question. Same setup, but listening to a signal on the air. "Beat note" is ~500 Hz. I turn the RIT so that the received signal is lower frequency - say 200 Hz. I transmit.

[Elecraft] What does the frequency readout mean?
