First, no one wants "firesafe" because it's far too complicated to operate. Heck, the vast majority of agencies want no more from their radios then an on/off switch, a volume control, and a PTT switch. No channel knob, because they only want one channel-that's it. heh.
But more to the point, we can't take licenses we've put in back out of radios, for Vikings. They're there forever. For the TK and NX radios, we have 72 hours to take them out. Once it's past that limit, they are permanent.
