I inserted the male ends from two cables together and then used the combined cable to connect the CH340 to the router. The ends connected to the JST PH connector were a loose fit.

Good quality! ### ⭐⭐⭐⭐⭐ It worked to mate rxtxlite to my uSDX+ V2 *by G***H on 29 August 2023* I used one of these to adapt my cellphone with the rxtxlite android app to my uSDX+ V2 qrp transceiver. Everything went together easily, and worked perfectly. Now I can change bands, modes, and adjust frequency with the phone instead of the buttons on the radio. Cheap and easy to do!
