Part one of a major new series describing a new HF transceiver design combining 'a high-performance receiver with a fairly standard transmitter'. Readers who have been followving the items in Pat Hawker's 'Techinical Topics' pages on the quest for tow-noise oscillators will recognise the provenance of the series. Part one introduces the project, and outline: some of the aims and achievement; of the design. The design of an HFtrans-ceiver today cannot easily be performed by one person. Although RF considerations must predominate, expertise in computer hardware and software as well as digital circuitry, is essential. Thus a team of three was formed, each with his own expertise, with a desire to design a transceiver with receive performance at least equal to the best currently on the commercial market, and one which could be reproduced by an experienced amateur constructor.
