tony.mayall1 (verified owner) –
Received mine today, sorry there was no wall PSU supplied, but I am very satisfied with the radio, had FUN setting up Zello and downloading Echolink and setting that up, took a while setting up to use the microphone, instead of the screen(default). All is working well.
