Especially if it ends up having 40 positions on it :-)

I have been SWLing with my K3 since I got it last year.  (Even more happily now that we have a sync detector -- thank you Elecraft!).  Managed, somehow, to keep straight where I was, and when one of the band select positions needed to be reset to the ham band range.  What is with this seemingly compulsive need to take something simple, straightforward,  and not oh so terribly hard to understand and turn it into a multi-headed monster?  :-)

I can also get around the bands (ham and SWBC) just fine. I suppose
the BAND switch is "straight forward" if you know that that it divides
the K3's entire HFcoverage range into ten "bands", each one having an
amateur radio allocation somewhere within:

0.5 to 3.0 MHz
3.0 to 4.8
4.8 to 6.0
6.to 9
9 to 13
13 to 17
17 to 19
19 to 23
23 to 26
26 to 30

It is understandable how general coverage users can be confused. The
BAND switch is really a HAM BAND switch with extended boundaries.

Frankly I see no problem with the way it is currently

implemented. I find a really simple way to get back into

the desired band "segment" is to make sure that the B

vfo is set to an appropriate frequency and do an A - B

swap.

BTW, as an old software engineer I can imagine the

can of worms that implementing a "GEN" set of

registers would be!

Hi Steve,

I'd like to do something along these lines. It's a nontrivial change  
to the firmware, but I've added it to the list.

tnx

This works pretty good. Thanks to all for the ideas! I learned a lot from this.

No can of worms please.....

The early bird gets the worm.

A rapid-transit shortwave band select would be pretty easy with the  
existing features and firmware of the K3.....set aside a group of  
memory channels, say 90-99, assign a frequency or frequency pair(A/B  
vfo)  from each shortwave band to each of the memories, label  
60M-49M-31M-25M-19M-16M-tertiary bands etc, 41M if you want a SW Rx  
mode/filter different from your 40m usual mode, add asterisks to the  
memory labels and bandhopping is yours.  Tune from there.  For more  
convenience there is the serial port and the family laptop.  Ham band  
switching stays ham band only, simple and direct.

I bandswitch by M>V 1 thru 9, from 160-10 meters, with 60 meters  
selected as above and in the K3 manual.  VFO A is starting point in  
SSB segment, VFO B the CW end.  Always the same start/filter/
bandwidth, no surprises from the K3's understanding of band limits.  
Band UP/DOWN is very handy to look quickly at another band and return  
same freq with only two keystrokes.
