Yes OpenSKY has the feature as do most PS TRS's to "Sting" or "STUN" a radio as well as the ability to turn one on and listen to it remotely. This as N_Jay has stated is from the APCO P-16 featureset. And as stated almost like an P-25 system each radio must "log on" at powerup, simular to how P-25 radios auto affiliate and can't be used as RX only units. Though OpenSKY has had its share of problems, it seems that it hhas come a long way in improvements and in PA has passed the "stress test" of suddenly having massive use without failure. The only real drawbacks I see with OpenSKY are the two big evils... No scanning, and NON P-25 compliant. As an stand alone in an world of interop, its an OK system. On the being an island when you really don't want to be alone it joins the ranks of that other great Harris/M-A Com/GE/Erriccsson bomber, the EDACS ProVoice, the iCOM iDAS, iCOM/Kenwood NXDN, and Motorola TRBO list of sorrow. Other than being not the best choice for Public Safety, its still an workable system.
