OK I obviously have no idea what a patch is cause what I though it was it isn't.

In our little sector of the radio spectrum on the Washoe County Regional Communications System 800Mhz EDACS that I monitor with Etrunker.....

They have a talkgroup of 0103(hex) 0259(dec). Under TrunkerDM it lists this TG as a patch. OK. Under groups with new radios it lists only about 4 radios(no radios have been defined). Under hits it lists 0 hits. oookkkk. Nothing affiliates with this TG. Yet when I listen to this TG I hear a variety of traffic on it. Tonight the dispatcher(s) are reffering to south and north units which is usually different dispatchers. And then one dispatcher replies to a request for info as "Blue" is closed. Blue is an entirely different TG.

So I am utterly confused. What is a patch? What is the relationship of a patch and a TG? Can a "linking" frequency(old term) be assigned as a TG on a trunking system? Meaning that 0259 is the patch TG and if different agencies/sectors/groups want to talk they use this universal TG?????? When is a radio "patched"? Is it automatic or transparent to the operator? When I monitor the patch TG what dictates what I hear and what I don't?

ACK.
