How far can you radio someone?

For example, if you and a friend are using handheld transceivers (HTs) with a typical output power of 5 watts, you can expect your range to be about 5 miles maximum . If you’re using a repeater, however, you should be able to talk much farther.

In particular, the 2m band extends from 144 MHz to 148 MHz. The FCC Rules say that any mode (FM, AM, SSB, CW, etc.) can be used on the band from 144.100 to 148.000 MHz. The FCC has restricted 144.0 to 144.100 MHz to CW operation only. … What Frequency Do I Use on 2 meters? 144.000-144.100CW (Continuous Wave, Morse Code)147.600-147.990FM Repeater InputsWhat Frequency Do I Use on 2 meters? – Ham Radio School www.hamradioschool.com › post › what-frequency-do-i-use-on-2-meters

Double this to give 11.2 miles . This assumes that both stations are at the same height above sea level. If one station is higher than the other, the answer will be greater than 11.2 miles. Providing that there are no obstacles between the two stations (buildings, hills, mountains, etc.)

For this reason, a microwave radio repeater with transmitter and receiver dishes mounted on 30-metre (100-foot) towers has a maximum range of approximately 50 km (30 miles) , whereas the maximum range will increase to approximately 80 km (50 miles) if the towers are raised to 90 metres (300 feet).

The 10 Meter Band consists of frequencies stretching from 28.000 to 29.700 MHz . This means that you can still use a standard CB antenna- just be sure to get an antenna that has a power rating that will handle the power output of your 10 meter radio.
