Interesting information....ESK EDACS systems

[ElroyJetson]

This is an interesting bit of trivia for you...


If an ESK-enabled radio which carries an outdated version of the system data, where the
ESK itself has been changed but the system channels are the same, is within range of the
system it was originally programmed with, it will act almost as if there's no system
in range.

But for two details:

1: When out of range, normally you can't switch groups while the radio is in CC SCAN.
But if it can hear the control channel (with the wrong ESK) then you CAN switch groups
though the radio will still not come out of CC scan.

2: When out of range, normally if you hit the PTT the radio will give a single "invalid" tone,
but if it can hear that control channel (with the wrong ESK) then about two seconds after
the first "invalid" tone, it will generate a second "invalid" tone.

This is not particularly useful except to verify the presence of an ESK control channel in
the radio's logical channel list, when you don't have the ESK or you do have one and it's not the right one.


Just thought I'd throw that one out there for general knowledge.
