Expert Electronics newest radio is the completely autonomous SDR (Software Defined Radio) DUC/DDC. The Russian made SunSDR2 transceiver with the newest ExpertSDR2 software and SDR-control panel E-Coder is going to be introduced at the Ham Radio 2014 in Friedrichshafen in 27 – 29 June. This was first announced at the Mykop 2013 Hamfest for the first time. The concept of Stand Alone or Software Based radios is not new, but this is an interesting step.
