How far can you talk on 2 meters?

On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. Typical reliable repeater range is about 25 miles (40 km). Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km).

What is the wavelength of the 2 meter band?

The band limits in the USA for the 2 Meter amateur band are 144-148MHz. 2 Meters refers to Wavelength. It means that the radio waves transmitted at 144 million times per second (MHz) are 2 meters in length.

How far can you talk on a repeater?

If your signal bounces off of just one repeater, the range can get up to 50 miles. With a strong network of repeaters, a transmission could be daisy-chained to span the country. A repeater can't receive and transmit at the same time on the same frequency, just like normal transceivers. This is called simplex.

How wide is a 2m FM signal?

Even though we talk about a signal being on a specific frequency, the signal actually spills out on either side of the frequency by about 8 kHz. This means that a typical FM signal is about 16 kHz wide. (You may recall that amateur 2m FM uses ±5 kHz frequency deviation.

How far can an 8 watt ham radio transmit?

What is the 2 meter calling frequency for single sideband?

The 2M SSB calling frequency is 144.200 MHz, so that is the first place to look for activity or to call CQ. SSB operation is not channelized like FM simplex and repeater operations, so you'll need to tune around to find other stations on the band.

What is the range of FM radio?
