So my TK8360 seems to be working fine but I've got a group of channels setup for my family to use and the TK-880 seems to be ignoring the codes. When I go to scan on the group that has the codes set, it's still picking up transmissions that I'm certain aren't using the same digital code, since one of the channels is a local tile store and I've changed the code just to make sure and both them and others on different channels are still coming through. I'm assuming there's an option I haven't checked in the programming software (KPG-49D). Anybody know what it is I've missed? Edit: Just learned something new. I was on ch1 with the code programmed, using the 8360 and when I pressed the monitor button, I could hear the store. So, apparently squelch has an impact (I recall reading that codes are a "type of squelch") so with that said, perhaps the "logic signal" section holds the key? My settings there are: Squelch Logic Type: Active Low Squelch Logic Signal: COR Access Logic Type: Active Low Access Logic Signal: Continous Horn Alert Logic Signal: Continous I'll take a look at the help file for the software I use for the 8360. The help file for some reason returns an error for the KPG-49D software. Bob
