Likely everything you need to know (except the answer to #2 & #5) will be on the
Batlabs website.
As for #2, it depends on what freqs are programmed into them. Likely you will need a license or be authorized on the frequencies. You need to find out what they are. You could get into big trouble if you transmitted an a local PD or FD channel, for instance.
For #5, a local ham operator could do that, or take them to your area Moto shop.
