David Minchin, VK5KK: An update on the mcHF SDR Transceiver and Microwave SDR

At SDRA 2015 in Friedrichshafen,the author presented an overview of the mcHF SDR HF transceiver and a discussion on using SDR for microwave operation. The SDRA 2016 presentation will provide a more technical discussion on the mcHF including the expanded feature sets and firmware development over the past 12 months. To assist current and potential mcHF project participants a summary of modifications, upgrades, test results and experiences will also be presented. The second part of the presentation will discuss utilising the mcHF UI controller hardware and source code with VHF/UHF SDR platforms. The current development of a stand alone 144 MHz transceiver incorporating an imbedded FREEDV 2400A decoder/encoder will be presented to promote more interest in this area. Some results from using this experimental "Digital VHF SDR" radio with microwave transverters, with both FREEDV 2400A and JT65a weak signal operation, will be tabled.
