Its not difficult to understand its just annoying. Essentially we're all in agreement that the radio can do it. I think that the firmware in the rig could actually make this happen 100% automatically. The only difference is that when operating cross band split you're going to have relays clicking when you tx. And depending on how its implemented to try and save the relays you may not be able to do QSK when using cross band split.
I'd be 100% ok with those limitations but having to explain to someone how to hit A/B and then only log in VFO A because you can't transmit from VFO B is going to be a pain. Then when you explain to them well actually you can transmit from VFO B but only if they are both in the same band. Once you get used to how well it works when you've got both in the same band it would just be nice to do it cross band. At that point you've got pretty much an SO2R without the full duplex capability. I suppose maybe I can turn off the VFO IND feature when others run the radio but then they're going to think its lame in that when ever they change the band on one VFO the other one changes too... I've been looking into doing a macro and no matter what it seems like the macro is going to be somewhat annoying in that you'll have to see the switching and what not. Seems like without source code you're going to have to be manually executing these scripts too. So anything I end up with is going to be a kludge and the kludge will be just as hard to explain as manually pushing the buttons... Oh well. Maybe we'll have some of these features by next FD. If one is willing to put up with a bit of relay switch delay all of this is 100% possible. Now its just a matter of if enough people feel its worth it to step a little bit away from the current K3's operating convention and make it happen. ~Brett (KC7OTG) On Sat, 2009-06-20 at 13:15 -0700, Bill W4ZV wrote: > > > Merv Schweigert wrote: > > > > I am some what confused with the issue.
