Re: [Elecraft] K3 VHf use
You guys know that there is also a feature that will automatically correct for this offset when changing modes. It automatically uses your pitch frequency as the offset. It was released several versions ago. Read through the release notes and you'll find it in there. ~Brett On Tue, 2009-09-22 at 19:55 -0700, Jessie Oberreuter wrote: As a frequent VHF contester, I know what you mean!

Re: [Elecraft] K3 VHf use
Excellent post! I was trying to remember where this was but wasn't remembering off the top of my head. Thanks for providing that for these guys. I think there are a good number of K3 users out there that wish they had a feature to do that one thing that bugs them and little do they know that there is something just for them in the rig They've just yet to stumble across it. We need more posts like this! ~BTH On Wed, 2009-09-23 at 00:15 -0400, Richard Ferch wrote: Maarten, There are two related but different configuration options for the situation you describe. The first option lets you use your CW paddles or key while the radio is in SSB mode. The newer option (so far in beta firmware only) adjusts the offset so that when you switch modes from SSB to CW, you do not have to retune the radio. The first one is documented in the current Owner's Manual; it is called CW-in-SSB. Quoting from the K3 Firmware Release Notes for firmware version 1.87: CW KEYING IN SSB MODES: While in SSB modes, you can now send CW without changing modes or using an offset. The other station will hear the signal at your CW pitch. This is especially useful on VHF bands when SSB signals can’t be copied. To enable this feature, go into CONFIG:CW WGHT and tap '1' until you see SSB +CW. You can also use this option for cross-mode QSOs. Interfaced logging software will record the QSO as an SSB QSO, since the radio is still in SSB mode. The second option was added in firmware beta release 3.19 and is not yet in the Owner's Manual. From the K3 Firmware Release Notes: AUTOMATIC CW VFO OFFSET ON MODE CHANGE: Allows switching quickly between SSB and CW mode without either you or the other station having to re-tune the VFO (often done on 6 meters and transverter bands). First, locate CONFIG:CW WGHT and tap '5' on the keypad until you see VFO OFS. From then on, when switching to CW mode from any other mode, the VFO will be offset by an amount equal to your sidetone pitch (as set using the PITCH switch in CW mode). If the sideband most recently used on this band is USB, the VFO will be shifted UP; if it was LSB, the VFO will be shifted DOWN. Note: If you make frequent use of this feature, you may want to use CW reverse on bands where you use USB, and CW normal on bands where you use LSB. This results in perfect pitch matching when listening to a CW signal and switching from SSB to CW. You must download and install beta release firmware 3.19 or newer to use this option; I believe it will be included in the next regular production release. 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

This results in perfect pitch matching when listening to a CW signal and switching from SSB to CW. The above paragraph may be corrected in the final release. When listening to a CW signal initially in SSB mode and then switching to CW or CW-Reverse mode (with VFO OFS enabled), there will often be a small change in pitch. By far the greatest source of error is that the signal had not tuned exactly to the correct pitch while still in SSB mode. Only one pitch of CW signal will give perfect matching between modes, and that is the sidetone pitch that has been configured for CW mode (using the PITCH button and VFO-B). If the CW signal is tuned *exactly* to that pitch while listening in SSB mode, there will be little or no change on switching to either CW or CW-Reverse. In practice, normal CW mode works fine for the VHF/UHF bands where the VFO OFS feature is useful. It is *not* necessary to use CW-Reverse... which is fortunate, because some logging software doesn't recognise CW-R correctly, and may reset the mode to CW when you aren't looking. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek __ 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] K3 VHf use
Yes I figured that one out. Going from SSB to CWrev I still have to retune (+600Hz) to copy CW as the CW signal is at zero beat. Going from CW to SSB I have to tune 600Hz down. If you work VHF/UHF you understand what a convenience it is when you change from SSB to CW mode, that the zero beat frequency shifts by whatever your selected CW pitch is so you do not have to retune again.
