I have a RadioShack Pro-106 that I am programming for a friend that just wants a single tower near his home on the radio. The site is 141 on the State DTRS. I have read the manual several times and can get it to scan the the Control Channel as it shows it has great signal strenght but it will not pickup any talkgroups. I do not have the programming cable to do this and our local radio shack is the one who sent him my way I am sure I am missing some specific setting in the System. Could somone please look and tell me how their settings are set up for the State DTR System in their Pro-106. Thank you.
