Radio Operation
The 2-Meter Ham Band is a popular radio band used by amateur radio
operators for civil defense. After a hurricane, earthquake or other
calamity, 90% of emergency coordination at the local level takes place
on this band. Listening to this band during an emergency can be
extremely valuable and even life saving. For most people, the
CCRadio2 will probably be their first experience with Ham radio.
We have preprogrammed some of the most popular frequencies into the
five memories of the CCRadio2. Different frequencies may be active at
your location, other than those preprogrammed into the memories. The
following are the frequencies and memory locations as they were origi-
nally preprogrammed:
1) 146.520
2) 146.760
3) 146.880
4) 146.940
5) 147.000
You can program your frequencies of interest into a memory location at
any time.
To scan the five memory channels when in 2-Meter Ham,
momentarily press both of the Up and Down Tuning Buttons
at once, the radio will scan the memories and automatically
stop when it detects a voice transmission. Raise the telescopic antenna
up fully in a vertical position. It is best to set the squelch level prior to
scanning the memory stations. See “Setting the Squelch” below.
SETTING THE SQUELCH
Background noise or static is present to some degree at every location
and on every frequency of the 2-Meter Ham Band. This is a normal con-
dition. If you set the squelch above the background noise level, the
radio will remain silent until a voice transmission is detected. It is best to
set the squelch as low as possible (to just before static is constant).
This way you can hear signals that may be weak. If you set the squelch
too high, you may miss some weak voice transmissions.
To adjust the squelch level, press and hold the main
Tuning Knob in for one second until the display changes.
Turn the Tuning Knob slowly clockwise from OFF
through 12 (increasing squelch) until the radio just becomes silent.
NOTE: Squelch operates on the 2-Meter Ham Band only
.
