From the developer:
NaP3 is a pan-adapter display program based on a combination of PowerSDR/IF from WU2X and PowerSDR v2.1.6 from Flex Radio. It communicates with the rig through LP-Bridge or LPB2, which greatly extends the capability of the rig by allowing multiple applications to easily connect to the rig and share its serial port.
