Sooo, I have done this before, but a while back when trbo first came out and we upgraded some existing systems. What should happen is tuner should allow you do a PA calibration so that the controller doesn't spaz out, and is aligned properly. A read and write to the station and boom, you are back on the air. After three different calls to tech support, turns out the newest version of tuner doesn't allow you to read a locked radio, go figure. Answer, download the older version in archives and that should work. I haven't tried this yet, but it would make sense. Very aggravating to say the least, such is life. More to follow. Rob
