K3: VFO B follows band changes on VFO A

[LY2IJ]

Hi,

Still learning - didn't find answer in manual or on reflector:

VFO B band changes when I change band on VFO A - is it normal?
Is it possible to change to "ICOM" behavior? - where VFO A and B are
independant - eg. VFO A on 160 and VFO B on 20 SSB and I can jump
betwen them with one push.

It's normal. You get two VFOs per band. The M1 - M4 memories are per band as well.

But this begs the question - which is also asked in another posting - how do you do cross band split? Not that this is common - I don't think I have have ever done it - but with my ICOM this is straightforward.

The frequency selected in VFO B is stored in memory and can be changed to whatever you want, and thus can be recalled again.

BUT - and this must be a bug - on my rig as soon as I get to far out of the VFO A band range (for example if on the 20 meter band when I tune below 13000) with the B VFO there is a click then a 3 to 5 S unit drop in signal strength.  Similar things happen on the other bands. This can't be right.  It appears that the B VFO is changing band pass filters even though I have no second receiver and am listening to the A VFO.

Definitely should not do this.

ALSO, strange things happen to the 30 meter band stored frequency when I try this. That is after observing that the signal drops as above, I noticed that the 30 meter band changed so that both VFO A changes to the frequency I had selected on the 20 meter band and the B VFO changes to the where I left the B VFO while on the 20 meter band before changing down to 30 meters.

It appears that if you tune the B VFO out of range then not only is the present band messed up but also at least the next lower band.

Even worse than above.

Yea I have the same problem and it drives me nuts. Trying to listen to the
SW bands causes all kinds of confusion with the "Band" button. I loose bands
and screw up others. What I wish is for is that the "band" button always
just select ham bands and not suddenly become some weird "band". I had the
wise idea of just using VFO B for SWLing and VFO A for standard hamming but
somehow the end up interacting and I eventually have to get the whole mess
straightened out. Otherwise I love this rig!

I spoke to Wayne at Visalia about this very problem. He says it
is "on the list". He has a scheme where if you venture outside the
ham bands a new frequency register is "spawned" and becomes
the "general coverage" register so the band up/down buttons
behave normally.
