I'm seeing a lot of the CCRs radios all over the place. Being a former cop (a very long time ago), I'm curious what's preventing someone from taking one of these and broadcasting on a VHF emergency frequency like, for example, 154.755?
I know very little about these radios.
Nothing. The cat was let out of the bag about 10 years ago when the FCC, ICE and every other agency dropped the ball and started allowing these fetid turds that some call a radio into the US en masse. The Summer of Love taught Chicago, NYC and other cities still on conventional analog that the availability of these devices pose a real threat to the RF spectrum. (Of course, Chicago PD is migrating to secure, fully encrypted system and NYC is doing the same now). Meantime, millions of these things are in the hands of unknowing consumers who don't know:
1- Most are not FCC certified for any consumer (license by rule) use on any frequency
2- Most consumers don't care about rules. They just want cheap "walkie-talkies" and hop on Chinazon and go wild.
3- The "prepper" community think they are the savior to all things "zombie apocalypse" and will magically enable seamless comms over hundreds of miles. License? We don't need no stinkin license! It's the end of the world as we know it, and we feel FINE!
4- The "cheap ham" community. Hung up on low rent, bottom of the barrel radio, these subpar performing radios seem to be like fast food for many new hams young and even older farts who could care less that these radios sound like crap on the air (low, muffled audio is a signature quality), have the worst front end of any radio (most have no filtering so even interference from an LED light drives them crazy), abysmal user interfaces with quirky issues like slow scan rates, difficult to enter frequencies/tones- but hey, you can buy three of these road apples for the price of one entry level Icom!
Those who want to infiltrate conventional analog systems have a cheap, low cost entry path to doing so. It takes very little to gleam the required information to pirate on such systems. Sure, it's "always been that way", but the cost of entry for quality commercial gear, acquiring software and cables, as well as a skill set to do so kept them out of most dirty hands. Not the case today thanks to the Internet, Chirp, and $30 turd radios!
