I agree with gmclam it is a "war of terminology", yes they do repeat the mobiles on the base frequency but it is not done in the normal fashion as a standard repeater (one input frequency and one output frequency) but if I can hear the mobile unit on the base frequency it is being repeated and I also agree with the CHP forum in that it is a very complex and complicated system but in my opinion that is why it sucks, if they used a normal radio system just like everyone else I wouldn’t be standing next to CHP officers in the field every day telling me I have better radio equipment than they have. I can’t even recall all the times I have witnessed a portable radio fly through the air because an extender wasn’t working on top of all the complaints about the car radio.
