Ooh, I am going to stay away from suggesting appliances for heating up
radios. I had "an unfortunate incident" when I was a QA engineer on a
transceiver while we were doing accelerated aging tests. "Someone" was
surreptitiously using the Russels GB-32 as a pizza-cooker during
all-nighters and they used the menu to change the temperature scale from F
to C.

I did not check (who assumes that people mess with your test gear? I was
young and naive) and punched it up to cycle repeatedly from -40 F to +149
F, instead it was going -40 C to +149 C. (300 F). It did the cycle a few
times and then the monitoring equipment attached to the radio began to cry
for help. The room was filled with the smell of "hot" and I shut down the
test to let things cool off.

The radio was of an unusual size and shape and the only way to fit it in
the test chamber was diagonally, with one end up in the air. The heat
warped the plastic case into a banana shape and the circuit boards managed
to maintain integrity (and functionality) with this strange shape. As
things cooled the prototype became locked in this new rather melty looking
form.

Since this was the only prototype it had to be present at an investors
meeting the next day. It would not sit flat on the table and looked like it
was assembled by Picasso
