I purchased 6 of hem. For myself and for my friends. All is fine. Initially I was doubtfull about CH340 chip used for CW line, but it works fine. Inteface has PTT and CW activity indicators, audio IN and OUT potentiometers to adjust levels Everything that one can expect. Recommended.
Exactly as described. Connected my FT-767GX (27 years old) to a 2007 laptop running LINUX and fired up WSJT-X and immediate success. Had to reduce the power output setting on WSJT-X to put out about 20Watts. Contacts immediately on 40, 30 and 20m. This is a wonderful piece of electronics which achieves as much as interfaces ten times the cost! No issues connecting to the software or the rig. Thanks very much Anton
