Jerry, I plan on building a new Main board with the regulators
and heatsinks on the rear of the board so any heat from them
doesn't go directly to the Teensy. I may try the switchers. My
temp - ~42C in an air-conditioned room, would like more margin if
used outdoors.

Downloaded and compiled version 66.7 here. Works ok and no
freeze.
(Still clicks when tuning though.)
What helped with me is keeping the Teensy cool. I use a small
fan in
Justin's kit. Without fan version 66.2 also froze.
*** I keep mine cool by eliminating sources of heat.? I replaced
the
linear 3-terminal regulators with Murata switchers.? No fan, no
freezes.
Can't hear any noise from them.? Any noise is drowned out by the
noise from
the display.? And the noise from the display is drowned out by
band noise.
