Fox hunt transmitter for the 2 meter amateurband

This is a foxhunttransmitter for the 2 meter band.
The transmitter in AM modulated with a sirene of alarm signals or by morse code from a PIC processor.
The PIC processor can also be used to switch the transmitter on or set the tones.
Without PIC processor continious sounds are transmitted.

Some data:
Powersupply: 3 to 5 V
Frequency range : 144 - 146MHz , determined by the crystal
Modulation : AM
Bandwidth: about 20kHz
Output power: 0dbm or 10dBm
Options: PIC processor does the extras
