VFO A/B modes?

Is there a way to make the VFO A/B change modes? I know it keeps the
same mode per band... seems everything is "per band" if I read the
manual correctly.

Normally I keep VFO A on CW, and VFO B on SSB, on each band. Is there a
way to do this without having to switch modes manually each time I swap
VFO's? Like when I am on 7005 CW and go to VFO B, I'll be on 7185 CW,
instead of LSB. Can this be done?

Thanks!!

Re: VFO A/B modes?

Chris -

I don't think there is a way to do this. I have wanted to do the same
thing, but so far, no luck, Perhaps one of the future firmware
revisions will include this feature. Like you, I also prefer to have
one VFO on CW and the other on SSB. Actually, it would be very helpful
to be able to have the last mode used on a band, together with which VFO
was active, be remembered too.

I am not sure how much storage room is available for that sort of thing
in the software. We're probably both a bit spoiled by the features on
our Mark V's - Hi! Still, I do love the quietness of the Elecraft
receiver.

Re: VFO A/B modes?

Agreed! If I could add only one item to the software, it would be that
separate modes could be stored with each VFO. This does come up from time
to time on the reflector but it seems there may not be enough "room" left to
be able to do this. Sure would be convenient. 73 es gud dxing -- Don N4HH

If you have KIO2 or KPA100 serial connection to your PC, you could
theoretically run some sort of macro at the PC end to recognise that you've
changed VFOs, and fixup stuff for you, then keep track if you change modes
so it can fixup properly next time.

Personally I'd throw together something in perl if I wanted this
functionality, but that's the kinda geek I am. Not sure how to do this sort
of thing on Windoze - maybe our favourite HRD author will chime in?

Of course, this doesn't help much if you're in the field without your
logging laptop.

Re: VFO A/B modes?

No need to do this on a PC ... a PIC / TinyAT / etc. 8 pin
microcontroller could easily be tied to the ATU/K2IO/etc header on the
control board where it could sniff for band changes, mode changes, etc.
and send back appropriate commands to make little corrections. I've been
meaning to do this forever -- first on my 706, and now on my K2 -- for
auto-adjusting the VFO for CW vs sideband (like the Yaesu rigs do).

In reply to this post by Don Nesbitt

A 'top of head thought'. I wonder if some added logic / control circuitry
could do the trick, overriding the existing firmware when 'split mode' is
required?
