My 2304 equipment consists of a Down East Microwave transverter and a Spectran 30 watt linear amplifier obtained from eBay seller "PyroJoseph".

I assembled this transverter from a kit and integrated with the amplifier in the spring of 2005. It made it on the air for the first time in the 2005 ARRL June VHF+ contest.

The transverter is usually driven with a Yaesu FT-817 at about 5W. There is a Bias-T outboard of the FT-817 to feed PTT-H over the IF coax. This way I can use a single radio to drive many transverters, switching with only an IF coax switch.

This is the DEMI Local Oscillator board (which appears to be derived from a KK7B design) with the parts on it.

The transverter's 10mw drive output is used to drive the Spectran amplifier. The amplifier is mounted on a heat sink salvaged from a dead Motorola 800 mhz commercial amplifier.

Slightly out of the picture is a DC-to-DC converter that supplies a few miliwats of (?v) power for the amplifier.
