to use very long range transmiter u should work at freq 2-30 mHz.
use it at night
use as more power as u can.
use an anttena with high gain (u gona pay with diraction)
look for ham radio ciruits.
for ex. 600 watt with 4 elenent dipole, can make a transmith from usa to middle est ( if the Rx station have 6dB gain , and normal sensetive)

Can you direct me to such a circuit - one which is not very expensive and has few kms range ?Or is there a simpler way for 2-way communication in 5-10 km range?
