Thanks for the reply. For EMA, they will normally talk on our VHF frequencies, but sometimes they'll say "Switch over to the 800mhz, so I was just wondering. Also with the high school, they have VHF Kenwood radios, for school to school use, and school to county dispatch use in case of emergency. I'm a senior in the high school, and I was just wondering, maybe one day I'll use the Signal Stalker on one of my scanners to see if I can find it, same with the 800mhz.
