Re: [Elecraft] Frequency shifts of KX3 when selecting CW?
Oops - yes, I did mean 700Hz!! Thank you for correcting me! On 27/07/2021 18:45, David Olean wrote: Hello Paul, I think you mean 700 Hz (not kHz) for the frequency. You can set the pitch of the CW note on your radio to fit your own ears. Older rigs just picked a freq and you had to live with it. My old Kenwood TS-820S used an 800 Hz CW offset as did my later Ten Tec OMNI V (a great cw radio). I don't have a KX3 but I suspect it is like my K3. If you are getting older and, ahem, more refined, you might notice that you like a lower CW note. That can be set to your preference, so when you tune to 14150.0 on SSB, the dial will indicate the zero beat frequency where the SSB sounds most natural. Switching to CW will adjust the oscillator frequency to produce the correct offset beatnote that you selected and the actual display frequency will be offset by that amount. If your favorite CW note is 700 Hz, then the dial will indicate 14.1507 or possibly 14149.3 depending on CW or CW REVERSE buttons. To make sure that you are correctly positioned for a QSO, you can hit the SPOT button. This will produce a tone that is equal to your CW note preference. You can easily compare the other station's CW note with the SPOT note and adjust your VFO until they sound the same. Human ears are good at comparing tone differences easily to 1 Hz or so. When it sounds equal, you are properly positioned on the exact same frequency as the station you are calling. The new rigs are wonderful when compared to how things were in say 1960 or so. There was a reason novices hung QSL cards on their wall. A contact was an almost rare occurrence! Now we quibble over a few Hz!

Re: [Elecraft] Frequency shifts of KX3 when selecting CW?
Tom, As an experiment, try tuning the KX3 to a valid ham band like 160 meters in AM mode, then switch to CW. What happens? 1.000 MHz is in the middle of the AM broadcast band, so that is not a good example. I am thinking perhaps this is built into the KX3 firmware to prevent transmitting CW on the AM broadcast band - but that is just a guess. 73, Don W3FPR On 7/26/2021 2:05 PM, Tom wrote: Hi I don't recall this happening before, but if I am tuned to a signal lets say at 1.000 MHz in AM and then I switch to CW, the frequency display on the radio changes to 1.600 MHz.
