I have been trying this idea as well. so far it has worked between Grand Rapids and Detroit along 96. I have not been able to test it in other areas as of yet. I don't see why it wouldn't work though. I have the complete system split between two banks with regular FM freq's between each of the control freqs so that the scanner with scan all freq's and not just the first one it comes to. I have also noticed that some of the control freq's are used for voice channels in some areas. All I got was part of the conversation and then the scanner moved on to the next control freq. so not a big problem with that so far. good luck
