I made this circuit a while back and the output waveform was only about 50Mhz and it was transmitting on the first harmonic, which was limiting the power. If you use a proper RF choke at the base of the second transistor and change the first coil to three turns, you should be able to get at least 2.5 miles with a properly sized dipole.
It looks from the schematic that you have 3 different tuning capacitors in there, but I only see one on the breadboard. Please explain? and did you personally test the 1km range?
what model radio
