Hi Steve,
How about a Take me back to the ham band macro button?
Yes, that's essentially what the scheme I described with the M1-M4

Here's how you could set it up with just one:
1. Go to the 160m band.
2. Set VFO A to
I wouldn't mind keeping BAND as a hamband-only control. However, in
this case it would be nice if the K3's band boundaries usng this
control did conform to the legal ham bands (i.e., 40m should end at
7.000, not 6.000 MHz). I suppose this would mean, for instance, when
you wander below 7.0 MHz,

If it's a K3, it's as simple friction fit with a spring to hold the knob
securely; just pull it off. Be sure to you don't lose the spring insert when
