So, you're saying the Unication treats Harris systems different?
Care to expound on that?
Don't see any warnings from Unication, on PPS, when it comes to that.
FWIW, the system I listen to, is Motorola.
I just recently, went back to PPS and, deleted all voice channels and left the CC and Alt CC frequencies.
Thus far, not seeing a major difference, I could be wrong but, not having a different radio to compare, I can't tell.
