You'll still be able to monitor the voice channels conventionally (as before trunk tracking scanners came about), you just won't be able to follow the conversation completely. For example, your scanner stops on the first frequency that is active and you'll hear the dist 1 dispatcher, then the next frequency your scanner stops on you'll hear a Dist 5 officer.Now this is weird. I am picking up sporatic chatter on Denver on my old BC200!!! How the heck can that be if ESK is on now!!?
I am glad I found this forum! I have been pulling my hair out for the last few hours while I figured out what was wrong with my scanner. I thought it was rebanding related, but no the answer is unfortunately that Denver is using ESK!
I don't really see the point of using it if the audio transmissions are still unencrypted, the only thing worse than no security is a false sense of security. I don't understand how it actually prevents either eavesdropping or intentional interference. It just makes old scanners less useful. It sounds like a lot of busy work for very little gain.
Try 160. Another user on another message found this worked for Lakewood and Wheatridge.Uniden is allowing me to beta test some new firmware for the 396 that includes ESK capabilities, only "problem" is, for it to work...I need to know the current ESK key that Denver (and others) are using.
Anyone know? It should be between 0 and 255. I can obviously find the key by trying each one utnil I hit the correct key...but if someone knows it...it'd be a big help getting me started!
That makes sense, but I think I just saw the "key" fly by a few seconds ago, and with a keyspace of only 255 possibilities it is pretty trivial to get on the system. It just means that to attack the system it takes a little bit more money to purchase the correct radio and an hour to brute force the key by hand--it doesn't really change the situation, just the hardware required for the attack.The main purpuse of ESK was not to block users out from listening but rather to make it more difficult for someone to program a radio to key up on the system and generate false radio traffic. So it really was not a waste of time or money if it saves having emergency equipment responding code to a fake call.
