Luke,
I've used JVcomm for years .... they have their latest demo version which works just like the real thing (you just have to go thru a pop-up every time you use it) .... if you like the program you can buy a key which erases the pop-up. The program uses your radio and a simple audio cable that connects from the audio out on your radio to the audio in on your sound card. free download of the demo version is available at:

Good luck, Bill A.
