I work at an outlying EMS station. Our bosses don't make it over here too often. Our 800 radio is having an issue with hearing the wrong people and now talking to the wrong people. I am not well versed on P25 systems. So don't crucify me if I use the wrong terminology.
Our agency has a talkgroup. A nearby agency the operates non-emergency services is not even listed in entities having a talkgroup.
The radio inside our station is a mobile unit, Motorola XTL 1500. It is tied into an desktop power supply. The channel selector does not stop at the last channel has it is turned. Just like an old TV dial it rolls right back from the last channel to the first. In this case there are 14 items stored. The first and last channel should be exactly the same, "EMS". But they are not.
The performance is inconsistent. Often we will hear the non-emergency service's dispatch and mobile units on our radio. Often but not always. A couple times by switching from the 1st channel to the 14th channel I will stop hearing them.
Most often I have to select the 14th channel to talk to our dispatcher. If I use the 1st channel, often/usually our dispatchers do not hear me.
Recently the channel selector was in the 14th channel position and the display correctly indicated "EMS". I tried to talk with our dispatcher. The non-emergency company's dispatcher answered me and told me that I was on the wrong frequency. I switched to the "EMS" in the 1st channel position. Nobody answered me and there was no beep as I keyed the mic. When I switched back to the EMS in the 14th channel position the other agency answered me again.
When we returned to the station an hour or two later, I was not hearing the non-emergency company's radio traffic and our dispatcher answered me. When I bring the issue up I get a lot of very well informed folks trying to explain how I have done something wrong. These well informed people understand trunk radio system less than I do. LOL.
Any ideas on what is wrong and how I might express it accurately to the powers that be?
