What frequencies can a ham technician use?
The privileges of a Technician Class operator license include operating an amateur station that may transmit on channels in any of 17 frequency bands above 50 MHz with up to 1,500 watts of power.
Is amateur radio FM or AM?

How far can a 100W ham radio transmit?
100W Ham Radio Range Although transmitter power doesn’t have much to do with the range, like the height of the antenna, a 100W ham radio can reach up to 10 miles (16 km) or higher with the right weather conditions, no obstructions, and clear grounds.
