Sounds like you've hit the limit for how many talkgroups you can have locked out (on the 245, it's 200- likely it's less for its older brother). I'd suggest reprogramming the bank, which I think should clear out the locked out talkgroups and include only those you want to hear. The other way would likely be to restore all the locked out talkgroups and deleting them. That might take a bit since there's no PC interface on the 235 however....73 Mike
