HAS BECOME VERY POPULAR.  BY TRANSFERRING PROCESSING TASKS TO SOFTWARE, SDR
TECHNOLOGY REDUCES THE HARDWARE COSTS, WHILE OFTEN INCREASING FEATURES AND

SDRPLAY WIDEBAND RECEIVERS.  THIS BRITISH BASED COMPANY HAS BEEN AROUND FOR
A FEW YEARS.  BEGINNING WITH THE RSP1, ALL OF THEIR PRODUCT MODEL NAMES
HAVE STARTED WITH RSP, SHORT FOR RADIO SPECTRUM PROCESSOR.  IN 2016,
