Problem Setting CW Offset to Zero
 
|
Reading KE7X's manual, I should be able to set the offset to zero by selecting CW WGHT from the CONFIG menu and then tapping the 5 button to select VFO nor. But, this procedure leaves the offset at around 50 KHz. Am I interpreting Fred's instructions incorrectly?
Thanks, John WA1EAZ |

Hi John,
I don't know where you are seeing 50 KHz. The change in VFO when changing from CW to SSB should be what you have set in you CW tone. Try these two exercises. Exercise Examine what happens when switching between CW and SSB with CW WGHT VFO set to NOR and when set to OFS. * Select CW mode and tune VFO A to some even CW frequency, such as 14.050.000. * Enter the CW WGHT menu and tap the key to select VFO NOR. * Exit the menu and switch between SSB and CW modes. With VFO NOR, VFO A remains constant. * Change to VFO OFS and repeat the experiment.With VFO OFS activated, the display shows 14.050.000 minus your CW pitch Exercise What happens if two stations are using SSB and decide to switch to CW with CW WGHT VFO OFS NOR and activated. With VFO OFS NOR, each station will have to re-tune the other to hear the CW tone. With VFO OFS activated, neither station will have to re-tune. Each station’s VFO will be automatically offset by the pitch amount. If you sometimes operate mixed mode, with you switching to CW and the other station on SSB, it is best to enable VFO OFS so the other station doesn't have to retune you when you switch from SSB to CW. 73, Fred KE7X ________________________________ From: Elecraft <[hidden email]> on behalf of stengrevics <[hidden email]> Sent: Friday, April 21, 2017 8:52 AM To: [hidden email] Subject: [Elecraft] Problem Setting CW Offset to Zero Reading KE7X's manual, I should be able to set the offset to zero by selecting CW WGHT from the CONFIG menu and then tapping the 5 button to select VFO nor.

Hi Fred,
Thanks very much for the reply. I tried the first exercise. With VFO NOR enabled, the frequency remains constant. With VFO OFS enabled, the frequency decreases by 60 KHz which, I guess, is my CW pitch. When I am operating, and i switch from SSB to CW, I have to retune which I find very inconvenient. You can lose a weak station while trying to retune. So, if I understand correctly, I should enable VFO OFS so I don’t have to retune? Or, should I set my CW tone to zero? I’m still a bit puzzled. 73, John WA1EAZ > On Apr 21, 2017, at 12:54 PM, Cady, Fred <[hidden email]> wrote: > > Hi John, > I don't know where you are seeing 50 KHz.

You have exceptional hearing in order to use a 60 KHz side tone. May it be .60 KHz (600 Hz)?

In reply to this post by stengrevics
John,
I think you mean 50Hz, not 50kHz. That offset is only used when using CW in SSB mode - and it should be set to the tone you want the receiving end to hear when you switch to CW. For normal operation (not CW in SSB), the CW offset is always equal to your sidetone pitch. The transmit signal will always be at the displayed frequency. It is the receive frequency that is shifted, and you do do not have to do anything. The reason for the shift is so you can hear the other hams signal at your chosen sidetone pitch. That is also why you want to tune a CW signal to your chosen sidetone pitch (zero-beat) so you will listen and transmit on the same frequency. 73, Don W3FPR On 4/21/2017 10:52 AM, stengrevics wrote: > Reading KE7X's manual, I should be able to set the offset to zero by > selecting CW WGHT from the CONFIG menu and then tapping the 5 button to > select VFO nor.
