Improving the 1.3GHz Portable Transverter

摘要

The new transverter I'm describing this month has several improvements. The local oscillator is much more compact and the main receive and transmit board has been simplified. There's also a better power amplifier which gives an output of a few watts, and there's a bandpass filter between the antenna switching relay and the antenna connector. And - for convenienceeverything is now in a single box!
