Worthless to me without additional critical key file.
The software was purchased for configuring a P25 TK-5410-k2 ver3 portable to set up receive only trunked talk groups. The software has the trunk network configuration settings locked/'grayed out' unless you have an advanced network key or system key file or USB key which I have been unable to locate anywhere. So the software is only partially usable for conventional only channel settings, which is of no use for anyone wanting to configure P25 trunked configurations.
