Hey guys, besides moving to new frequencies they could be doing one of two things:
1.) Operating full duplex like the CHP does - With dispatch only on the repeater output freq and mobile units on the input (which is not being repeated).
-OR-
2.) Operating half-duplex on the output frequencies. The radio towers used by these channels are high up (in the sierra foothills) so you can hear dispatch being transmitted out of them, but the mobile units are too far away to hear. However, because the towers are at a higher altitude they have line of sight with the mobiles so dispatch can hear them. If this were the case, you would be able to hear the full conversation with a mobile unit on the output when you were nearby (within a mile or so) but only dispatch the rest of the time when the mobiles were too far away. Doesn't this match the earlier description of what seems to be going on?
