Thanks, seems for me i do have to launch the plug in each time for them to work but I that’s not really much hassle, i might look into getting an external powered USB hub, 'I’m not really that clued up on technical stuff and to be honest I didn’t know there was more than one type of USB hub, the one I am using just plugs into the PC.
I am getting faster at changing the frequency now so can usually do it it before ATC starts asking me to respond! and I have figured how to change my transponder now as that was causing me some confusion!
