I use a Gelena crystal radio - no batteries, no tooth floss.

Well, the original poster said he traveled alot. If he used rechargeable,
he might have to carry around a charger and he certainly would have to
have
to find a power source to charge the batteries. This may or may not be a
problem for the original poster, I can't know.

Oh, you also posted:

"Analog dials are dead! In this day and age, why rely on tooth floss to
turn
a dial?"

Why do you restring dial cords with tooth floss? Real dial cord is
available. If you want a substitute, try braided dacron fishing line.
