No problem. In general is what I meant. Many will stumble into threads down road well after they close. I know the owner/ user is a valid user of a system. Allot of smaller entities don't know if they had got a radio and passed it by the techs in house or admin of the system they may allow it and be programmed by them for use for the user. Most are afraid to ask, don't know, can't afford it, or have policies already prohibiting it. Others dont. Valid IDs are issued on the equipment and such then the radio is given a clean bill of health by the techs and admin after being at the bench.
Motorola could solve that problem of the random unintentionally person affiliating during a passive scan programmed wrong however since they are not in the business of scanning they ignored that simple problem fix. Other manufacturers have passive scan options to not affiliate. Motorola felt the rx only would be more useful and valid users be monitoring. Though say the town over has radios and programs them up to just monitor a trs they would need now a valid radio Id for each unit, rx only the radio which is useless unless it is public works monitoring and possibly pay subscription fees on the system even though they are just rx'ing the talkgroups still affiliating with the sites. Rx only in trs was meant for pw or a other entity who uses the same system but different talkgroups and given access to monitor without transmitting public safety or vice versa however the entity decided to do it.
I'm following you. I know each system manager/admin run their systems how they see fit. Example: Take the two XTS5000's assigned to me. We have all primary dispatch talkgroups programmed, i.e. County fire, city fire, EMS/Rescue, Law/Sheriff's office, and City PD, all OPS TG's and some of the LAW TAC TG's. My agency, Red Cross, is dispatched on our county fire talkgroup (with 2 tone paging on the VHF side which is permanently patched to the 800 TG), however we have two talkgroups on the system that we primarily use. They're called RED CR1 & RED CR2. Every public safety agency in the county has RED CR1 in their radios, but only us, our Emergency Services Chief, and 911 Director have RED CR2 in their portables. Say if we need to talk to a Sheriff's Deputy that went on a call with us, instead having to go through a dispatcher we can just switch over to whatever appropriate TG and contact them directly. No asking for "permission ".
I can tell you though on our system there are no RX only talkgroups programmed in any radio on our system. The philosophy is that if you're not authorized to transmit/have access to a talkgroup then you don't need to listen either, which makes sense. We've got a number of sensitive TG's related to LEO's & a couple are encrypted.
Thanks for the understanding!
