Details for System 11
About System 11:
The C.A.R.L.A. 11 repeater is located in the Walnut Creek / Plesant Hill area at the C.A.R.L.A. Lab where all of our repeaters are assembled, tested, cursed at, repaired, and modified. This is also where the EchoIRLP, and certain other links join the system. It has been reduced in power & coverage due to PAVE PAWS.
How the Local PL works in a Dual PL System
This particular repeater in the C.A.R.L.A. System has a Dual PL. If you use the Link PL, your audio is carried over the entire network of repeaters, and you will be able to hear the audio from any and all other repeaters in the network. If you wish to have a local conversation on the repeater just use the Local PL. Your audio will come out only on the local system and you will not hear link audio coming from other repeaters in the network. When you finish your local conversation, the link will automatically re-establish itself in several seconds.
A couple of things to keep in mind:

A couple of things to keep in mind:
- If you pause for an extended time during your local conversation the link audio may come back. Just key up with the Local PL to mute incoming link traffic and continue your local conversation.
- Remember, if there is a conversation in progress elsewhere on the network, you will not interfere with it if you hold a conversation on the repeater while using the Local PL.
- If you want link audio to come back right away just "kerchunk" the machine you're on with the Link PL.
- There is a different courtesy tone for local traffic and incoming link traffic so you'll be able to distinguish from which direction the audio traffic is originating.
