The Mosquito 1 Watt AM Transmitter has been designed to cater for the new 1 Watt Low Power AM standards being introduced worldwide, (for example in Scandinavia and the Netherlands).
Using Class E technology, with extremely linear modulation characteristics, suited for high quality, amplitude modulation.
The modulation range is 0 to 110%, and is optimised for 50% modulation for the Netherlands.
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. The synthesizer is preset to 1485kHz for the Netherlands.
The Mosquito employs "Class E" output technology and provides the full 1 Watt carrier, the modulator stages includes both over current and thermal shutdown.
The modulation stage can provide 0 to 110% modulation and has been
optimised for 50% modulation for the Netherlands.
The Mosquito also has a two channel mixer for either Stereo to Mono or twin channel Mono audio sources.
The Mosquito printed circuit board uses a grounding technique that splits the RF and Audio grounds, as well as providing and external grounding point. In addition a new external "universal"power supply provides regulated DC power to the transmitter, supplied with county specific power leads for the EU.
Fully built and tested, and supplied with "universal" switch mode power supply, standard 3 meter wire antenna and audio cable.
