Low Powered or Itinerant
Frequencies are often used for construction sites, events, drive-through
windows, parking attendants, churches, warehouses, and other places, just to
name a few, where the activity is confined to a fairly small area. You can buy
radios that operate on these frequencies at Sam's, Radio Shack, Office Depot,
and just about any place else that sells business communication equipment. The
radios require an FCC license, but I have a feeling there are a lot more people
and businesses using the radios than there are licenses. I believe it's
possible to buy the radio first and deal with the paper work later. If you are
going to an airshow, stock show, race, mall, circus, street festival,
convention, etc. it's always a good idea to have these frequencies handy to
listen in on the behind the scenes operations. Another frequency range the low
powered radios might show up on is the business band 460.6625- 464.9875 on the
split frequencies. For example, 464.6625(low power) compared to 464.625 (full
power). The 4 digits to the right of the decimal point will be 12.5Khz away
from the normal full power business frequencies. Many malls and large building
operations can be found here.
Here are some of the common frequencies used. Mode is FMN.
