[TrunkCom] PSR500/600 scanners capable of tracking ESK systems?

[Jeff Kenyon]

Hi everyone, I  was just reading around on radioreference.com that the
PSR500 and 600 scanners are capable of decoding and tracking ESK systems?
I thought ESK  were meant to not be able to be tracked?
	Also, what is the status of new EDACS systems coming out with ESK?
I see Denver is testing ESK and that Lakewood has it, though from seeing
Lakewood's  talkgroups they are mostly analogue?  Any more ESK  systems
rumored to be coming?
