Re: In car communication
This is why you shouldn't use Baofengs, lol: https://docs.fcc.gov/public/attachments/DA-18-801A1.pdf
According to that document, the 400-520 MHz range is legal, and mine are being operated in that range, so I'm not concerned.
My read of that document leads me to concur. We run our Baofengs on GMRS channels, therefore OK.
