Also known as 6 Meters or The Magic Band. Good VHF ground wave coverage up to several hundred miles on SSB. 1200 miles or more on openings such as Sporadic-E, F2 layer skip, meteor scatter, aurora, inversions and some EME (Earth Moon Earth). Operators have worked the world with fairly modest stations. Some FM and repeater activity.
The popular 2 meter band. Generally shorter groundwave distances of around 200 miles can be expected on this band with a modest SSB or CW station. Good mobile FM band. Lots of local FM communications on repeaters with up to 150 miles on some "machines". Lots of repeaters are linked together for even greater coverage. The IRLP (Internet Radio Linking Project) is very popular on repeaters linking to the internet all over the world! Also a good band for packet radio. There is also lots of satellite activity, EME and terrestrial DX for hams doing weak signal work (QRP). You can expect many of the same kinds of openings on 2 meters as you will experience on 6 meters.
222-225 MHz 1-1/4 Meters.
Not as much activity as 2 meters and no satellite activity.
Also known as 70 centimeters (cm). This is the lowest frequency amateur UHF band. Groundwave coverage is quite limited compared to 2 meters due to high absorption. Satellite, EME and terrestrial DXing are popular on this band. Fast scan TV has also found a home on 430 MHz. Lots of FM activity between 440-450 MHz. Lots of machines are linked to 2 meters! The longest Element of a beam for this band is about 12 to 13 inches on the low end!
902 - 928MHz
Not much activity on this band so far due to a lack of suitable equipment.
Also this is a shared band with other services.
1.2 GHz is a HUGE band with lots of room for experimenters. EME and satellite are popular up here and in some parts of the US there are very active FM repeaters. Antennas are VERY small! Not a lot of terrestrial DXing but during contests there is some activity. Antennas for small signal work are quite impressive with lots of elements on short booms. Dishes are practical on this band.
GETTING CLOSER TO LIGHT!
Above 1300 MHz Amateur radio has allocations all the way from here to light and all kinds of room for experimentation with microwaves and frequencies approaching light. Lasers anyone?
