I like the suction cup idea, as I want to be able to take this out in
the field...literally...and don't want the extra weight. Still, trying
to get suction on a rock might be tough...

"?BITX doesn't have enough mass to withstand the press without holding
the case."

When I toured the Kirby vacuum plant in the early eighties, I was made
aware of a manufacturing ‘trick’ that has all but disappeared, that
might come in handy for some of us. That ‘trick’ was to make items
heavier than necessary to imply a sense of worth was equivalent to
weight. The thinking was if two irons or two vacuums were placed side
by side and then lifted individually by a homemaker (notice how
politically correct I can be), the homemaker would likely choose the
heavier of each as the higher quality. Of course homemakers are better
informed today, so weight where not needed is eliminated.

Jack,

Add a lead bar, like used for melting to make fishing sinkers to weight
down that chassis enough so you can push against the front panel. Just
another choice. Or throw in a couple of old transformers for fun and mass.

Or put a suction cup on the bottom of the case…...

You could place the switch further away from the tuning knob. The
problem with using the encoder switch for something used frequently is
that the ?BITX doesn't have enough mass to withstand the press without
holding the case. (I'm using a light-weight case, but with rubber
feet.) That's why I'm putting the CW message switches on the top of
the case, since pushing down on a NO switch causes no problems.

I'll play around with that and see how it works...

I love your idea, Jack, only my personal preferences are slightly
different. If it were me, I'd have the separate NO switch be the Band
switch and use the encoder switch as the tuning select
(fine/medium/coarse).

My thought is that with my clumsy fingers I might accidentally
activate the encoder switch while tuning, and switching the tuning
rate when that happens would be a lot less annoying that switching
bands. ;-)
