      The Coil could be made from SWG 18, 5 turns, diameter 5mm.
      Please remember to subscribe you haven't done so already.

      @@hecanet Thanks for info. You forgot to write into schematic value about variable capacitor joined to coil. Can you tell me please?

      @@fabriziolongo83 The value is 30pf. Sorry about the omission, ... that's probably because we were reusing the part from another video where the part was shown (ruclips.net/video/emvvEL9QdwU/видео.html).

    how you know the frequency you transmitt?

      The Formula for Frequency is 1/(2pi*sqrt(LC)) where L = inductance and C = Capacitance. Pi = 22/7.
