Review on Gearmo 4-Port USB to Serial RS232 Adapter with FTDI Chipset, Compatible with Windows 10, 8, 7, XP, Linux, Mac - Enhanced ESD and Surge Protection by Luis Esquivel

Bought this for use with PowerSDR and WSJT-X rather than messing around with virtual serial port programs as both programs run on the same computer and also bought a null modem adapter (female to female) and connected the two cables together. A very simple solution, although a little overkill, leaves two additional RS-232 ports for antenna/rotor control in the future, and is probably slightly cheaper than some of the 'virtual' serial port options that do the same.
