Two versions, delivering either 50 watts or 100 watts of RMS power into a 50-ohm load. This equates to over 120 or 220 watts peak power driven up to 100% modulation.

The DC-Balanced Power Amplifier is wideband, and the output is filtered to suit the frequency. This transmitter employs a Pulse Width Modulator which makes the transmitter very efficient. With approximately 70% efficiency little energy is lost through heat from the circuitry. The Transmitter circuit design uses a CMOS oscillator in a Phase-locked loop circuit for accuracy and ease of frequency selection. It is very stable and therefore does not drift off frequency. The Phase Lock circuit provides selection in 9KHz steps, so that the unit can beused in the UK or Europe, for the 9KHz spacing between channels.

For use in the USA and other parts of the World where 10kHz is used between channels a different Crystal will be fitted as requested. Four rugged Power MOSFETs are also used on the RF output stage, which drives the output transformer. High voltage rated components are used in the output section.

Audio input is via an XLR socket Balanced input 0dB to +8dB for 100% adjustable by the volume control on the front panel.

The transmitter is housed in a Steel box with an Aluminium front panel.

Ventilation holes to improve air flow for component cooling. Cooling fans are used on this model which are used to force cool the power transistor block.
