Digital Television Tests – Bulletin No.7

Transmission of the unmodulated CW carrier continues on 506 MHz, with horizontal polarisation. Reception reports are welcome.

Four power amplifier modules have been constructed and tested one-at-a-time with the digital exciter. Their gain and linearity match within half a dB. The four modules will operate in parallel to achieve the licensed power.

A 4-way drive splitter and 4-way output combiner have been designed and are under construction.

The exciter and power amplifier will be demonstrated at our monthly Branch Meeting, on the 28th of March. (Tawa Community Centre, Cambridge Street, Tawa. All welcome, supper will be provided.)
