Lately I've been scanning the GMRS band (in the process of building a repeater and what to hear what freqs are active and which ones are not) For a while I've been coming across some users on 462.7125 with a DPL of 731, doing a little more listening I figure out it is one of the local hospitals Security, now here is the weird thing last I knew the Hospital was using a VHF Trbo system on 155.235. How here is were it gets even stranger, when I hear them talking on FRS/GMRS 7 the 155.235 freq becomes active with Trbo noise. And by listening on FRS 7 you can indeed tell they are using digital radios buy the echoing you hear in the background when you have two radios in close proximity. If I didn't know any better I'd say this is illegal......
