Unencrypted SLERS Talkgroups

[RF-Burns]

If I were to program my Harris Radios with SLERS for counties that are unencrypted, will a XG100M / XL200 track it? I know its an ESK System but don't know enough about EDACS so I thought I'd ask. I regularly visit Okeechobee County and would like to listen to fire when I am there if possible.

Nope. ESK prevents unauthorized subscriber units from accessing the control channel data.

Even with "Unregistered Affiliation?"

Yep. You would be playing with fire even attempting to try.

Copy, no go on passively listening.

I guess I don't understand the comment of "playing with fire." If it's programmed as "unregistered" it's passively listening to the control channel, meaning nobody would ever know.

Radios require the ESK, enhanced security key to access the control channel. The whole point of it is to keep "all" unathorized subscriber units from accessing the control channel.

Okay, you keep saying the word "subscriber". The reason for unaffiliated scan or in the case of a Harris radio, unregistered affiliation, is because it is not a subscriber radio. My guess is without having an ESK the radio will not identify/decode the control channel, making unregistered affiliation not work.

You obviously know more about the system than I do which is the reason I asked the question in the first place so I guess I will leave it at that.

Because it would have to be a "subscriber unit" to get any L3H EDACS radio authorized access to the control channel. You have to have the "radio" provisioned for ESK (feature most be enabled) and have the "security key".

This is not the same as a Motorola "system key", which only blocks access to programming the system info with the CPA.

The control channel is actually coded to prevent access without the ESK. An authorized card and card reader are involved in the process not just RPM.

Thank you for the explanation, that now makes more sense.

ESK was implemented as a stop gap measure to prevent rogue EDACS radios on EDACS systems. Which was requested as a result of an incident involving rogue EDACS radios.Think of it as a precursor to LLE.

What's the end objective?

What's the end objective?

Pretty sure the title of the thread says what the end objective was. Listen to non-encrypted Talkgroups, example some local fire departments that use SLERS.
