radio

FM Crystal Radio

L - 4 turns #18 copper or silver wire, 12mm inside diameter, tapped at 2.5 turns

Ant - 7 inches of #18 bare copper wire

C1 - 18 pF ceramic capacitor

C2 - 50 pF air variable capacitor (? for 93.5MHz)

D - 1N34 diode or rock crystal

R - 150K resistor

  1. How to tune simplest FMsimplest FM at 93.5MHz radio station by fixed value of C1 (18pF), C2? (any formula would very helpful so that I can tune to any radio station)

  2. Can I use diode 1N4007 instead of 1N34?
