I also Have a question Regarding my 396xt unitrunker and using windows 7 pro 64 bit. i used to use unitrunker retro with the black screen and red and green config and loved it when decoding my 396t. Now circumstances have changed, ive changed OS to win 7 pro 64 bit i got the 396xt and i tried to use retro and got "closed without saving" and retro wouldnt open. so i went with a newer version of UT, which before now couldnt get working anyway even on xp with the 396t.. i still cant get 23 build of UT to work or hear the control channel, or decode it. It seems not as easy to pickup or decode as retro was. I need to know what im doing wrong? i prefer the setup retro had but looking at my options nothing really works on a 64bit OS. on a Toshiba Lappy. I also wondered if UT decodes EDACS and How Strong the signal Has to be to do so? I probably need step by step instructions for any of this since it seems im missing something... Thanks Just at a loss to figure this all out...
