What to expect on the 2 Meter Ham
Probably the most popular ham band in use today is the
2 meter band.
Virtually every ham, young and old, has this band in his or
her shack. The primary focus of ham radio operation on this band is using
FM (frequency modulation). In addition, most who use this band do it in
the area of the band set aside for repeater operations and it is very popular with new hams holding a
The 2 meter band covers
from 144 to 148 mHz. It is easily received by most scanners. It is a VHF
(very high frequency) band and has the advantage of having very
small antennas and being able to achieve high gain
from them, even on a city lot.
For those of you not familiar with
repeaters, I will provide a brief explanation of their operation. These
consist of a transmitter and receiver, usually located at a very high
point in the average terrain with a gain type antenna mounted as high on a
tower as is possible.
Since vhf radio signals are mostly "line of
site", the repeater site's high location enables the equipment to "see"
farther than it would if it was located at ground level. This set up
allows them to receive weaker signals, such as from a handy talkie, and
rebroadcast them through the transmitter and high antenna at the repeater
site. This effectively gives you the same or greater range as if you
were sitting on the hill using your own equipment!
On the 2 meter
band, the input and output frequencies of the repeater are separated by a
spacing of 600 kHz. Which can be either plus or minus the repeater output
frequency. Usually everything is minus 600 kHz. Up to 147 mHz. Where it
changes to plus 600 kHz. In other words you transmit on one frequency (
the INPUT )...the repeater hears it....and repeats it on a different

If you want to listen to the
repeaters, program your scanner to the OUTPUT frequency of the repeater.
In most areas there will be lots of repeaters from which to choose.
All FM work is done with vertically polarized antennas because
they are much easier to design and build for mobile and portable operation
than are horizontal ones. All SSB (single sideband) work on 2 meters is
conducted for simplex in the area of 144.200 and is horizontally
polarized. Please note the difference in polarity !
equipment is readily available and the cost is not outrageous. For the
best of both worlds, consider a handy talkie capable of 5 watts output.
You can use this inside on a power supply and with a large outdoor antenna
array or you can use it mobile with an external antenna or finally
portable with the normally supplied "rubber duck"antenna.
more powerful mobile rigs can be purchased new or used and either used as
intended in your car, truck, van, boat, etc or use them as a "base
station" in your home using a power supply.
