Bunch? Umm no, its done with software. A few keypresses, thats it. Most of the things radio systems do now is done with software. The days of having to do all your "patching" with lots of hardware, and programming are over. Welcome to 2012, about to be 2013. The age of VoIP, IP25, OTAR, P-25 Phase II (TDMA digital where you can now have two slots per tg, and two slots per frequency in conventional). Welcome to the point where if you blink, SDR will be the new standard for communications. We have scanners that do things that were said to be impossible just a couple of years ago. We have radios that can do multiple frequency bands at the same time, as well as both analog and digital at the same time, and oh yeah, trunking and conventional at the same time. If you had told me this would be possible now just ten years ago, I would have wanted to sample the drugs you were on. Now, I ask you, what can we do wityh the next generation of communications?
