Any CERT team should not be using the cheapest radios they can find. In that case, stick with cell phones or zello.
For a club, why wine, just use FRS radios for $15/each and not worry about licensing.
For GMRS, you are required to use a GMRS certified radio, not a MARS ham radio. I've bought plenty of Kenwoods for what a majority of those certified CCRs cost.
There are too many places that people want to be cheap where they absolutely shouldn't. CERT is working with someone's life. Motorcycle clubs, you are riding a $45,000+ bike, and won't spend a few hundred bucks on a decent radio? I just don't get it. It's not like you won't spend money, you just won't spend it on the appropriate radio communications because there are $11.99 radios on amazon and "that's such a deal, it just has to work well enough". The options are there, you just won't hear it: 1) Stick with FRS, and have no licensing, 2) Have every member responsible for their own GMRS license or 3) get appropriate LMR licenses and radios, which in the long run doesn't actually cost more when you drag it out over a 20+ year lifecycle.
