Mosquito One Watt AM medium Wave Transmitter

Mosquito One Watt AM AM Transmitter

Using Class E technology with series modulation, giving extremely linear modulation characteristics, suited for high quality, amplitude modulation.

The output is protected from a short circuit to ground, and also has over current and  thermal shutdown to protect the output stage if the antenna is badly tuned.

The Mosquito transmitter is ready built and ready to run...at an affordable price...with the performance and features of units costing many times the price...!

The Mosquito employs a crystal controlled frequency synthesizer for accurate tuning and drift free frequency stability.
