Hand-held Radios
Hand-held
Radios (also known as Walkie-Talkies) provide simple and direct
two-way communications for the Bigfoot Hunter. They allow all members
of the party to maintain constant communication on the same frequency. Unlike
cellphones,radios don't rely on towers to maintain a connection. This makes
them somewhat more reliable than cell phones in remote areas for short
distance communications. They are easily clipped on a belt or stuffed
in a shirt pocket and having one will permit you to save your cellphone
for emergency situations.
Hand-held
Radios are portable, bi-directional radio
transceivers. Most units have a half-duplex (only one party can receive
or transmit at a time)
channel and a push-to-talk switch that starts transmission. Most newer
models look like a cellular telephone handset with an antenna
sticking out of the
top.
The advantages to having a radio with you are many. By maintaining
constant communications, you can talk to members who are straggling behind your
group without yelling or turning back and others can ask you to hold up
if something has gone wrong. You can also notify basecamp
that you are on your way in at the end of a day of searching.
Hand-held radio range can vary depending upon the radio. There are low
and high power models. Even a powerful commercial walkie-talkie is
limited to a few
watts of power output and a small antenna (the physical size of the
device limits both battery capacity and antenna size). Hand-held
communication range is typically quite short, not exceeding the
line-of-sight distance to the horizon in the open, and even less
in built-up areas, within buildings, or underground. Many radio
services permit the use of a repeater
which is located at some high point within the desired coverage area.
The repeater listens on one frequency and retransmits on another, so
that reliable hand-held to hand-held unit range can be extended to a
few score miles (kilometers) or further, using repeaters linked
together.
The hand-held
radio has now become popular with the new U.S. Family Radio Service
(FRS) and similar unlicensed services in other countries. FRS
hand held radios have proper super heterodyne receivers
and are a useful communication tool for Bigfoot hunting.
Operation in the Family Radio Service is restricted to hand held radios
limited to 500 milliwatts of effective RF power. Some FRS models also
include the surrounding General Mobile Radio Service (GMRS) channels,
which require a license.
When
shopping for a radio, you will want one that is durable and dependable.You may also
want to consider purchasing models that allow a headset, leaving your
hands free to move branches out of the way, hold a walking stick, or
climb rocks. Another feature to look for is VOX or voice operated
transmission switch which detects your voice when you speak so
that you don't have to keep keying the radio to talk.
