What's the capacitance of variable capacitors found in clock-radios ?
I want to make a pizza-box antena and can't find 10-365pF.

Thank you.


It's not at all critical. Use whatever you have. All it will affect is the
tuning range.

This calculator http://www.mindspring.com/~loop_ante...loop_calc4.htm
needs the value of capacitance, so that I know how many turns I need to
wind up, as well as spacing, to cover AM band, tipically 530-1710kHz.
