[Spooks] how to make a really cheap shortwave transmitter(slightlyOT)

[Colin McDonald]

range would be about fifty feet.
with the 6 inches of antenna on it, maybe not even that.
For an even slightly efficient antenna, you would need a quarter wave long
wire, which for 1 MHZ is around 234 feet.
You could get away with some sort of helical coil, which would be around 468
feet long wrapped around a vertical insulator.
You could potentially transmit from california to texas using a quarter wave
long wire with that tiny amount of power coming out of the oscelator, but
only under perfect conditions.
even Amateurs using 1KW of power with large loops or long wires on 1.8MHZ
have a tough time making it consistently out of their own state never mind
from coast to coast.
regards
Colin
