Chirp - Question (Newbie to programming)

[WSEZ969]

Can anyone tell me what we would use this programming screen for inside CHIRP ? Can you give an example and purpose

Some radios allow “selective calling” where you can send a code to one specific radio and it will listen while other radios ignore you.

I appreciate your reply. Thank you

I'm aware of the use of DTMF codes to send instructions to a repeater or other device. Are you saying they can be used HT-to-HT or mobile-to-mobile to determine who receives your signal? Yes, I know there's no such thing as true security with any unencrypted radio signal, but I can envision situations where it would help reduce confusion.

KINDA ..

IF all the radios are compatible with the feature and IF all the radios are correctly configured, you can use the Group Call (also has other names depending on the manufacture) feature to talk to only certain radios in your group.

HOWEVER - 

Radios not configured to do this and radios not compatible will ALL HEAR everything you say — Basically it is a fancy squelch or call-tone limiting only what the radios configured for your groups can hear (they can only hear their group), but all other radios can still hear everything.

I was assuming they could. That's what I mean that there's no security with a radio signal.

I can see where that might prove useful if you're working with a large group of people where some things need to be heard by everyone, but some things only need to go to a subgroup. I have no use for it now, but there were times in the past when I would have found it helpful. Interesting to know.
