3.7 Tips to obtain Maximum Radio Range
For best results when operating in the open field an all-round obstacle free location
and a vertically hold antenna are the most important requirements. The receiving/
transmitting range will be reduced partly
−
when the radio is operated within, or nearby large metal structures,
−
when the own body or persons very close are screening the antenna,
−
when mayor obstacles exist between the transceiver and the station being
called, like aircraft, vehicles, buildings, mountains, etc.
−
when strong high frequency sources like ignition systems or electromotors are
nearby.
Never transmit without an antenna!
Make sure, external antenna is DC grounded!
Obtain a geographic line of sight location to 'see' the station called!
When using the transceiver in buildings, vehicles or aircraft, the radio should always
be operated on a suitable external antenna.
CAUTION:
During Transmit mode, keep antenna radiator tip at least 10 cm
away from head or skin of the body!
Hold antenna neither close to your skin, eyes, other electronic
equipment, nor touch it!
3.8 Functional Checks
When the transceiver FSG 5W does not operate correctly, check the following:
•
Is desired operational frequency adjusted?
•
Carry out a battery test without any charger or external supply connected.
•
Switch OFF squelch when receiving weak signals.
•
Operate radio without any accessory. Same malfunction?
•
Is helical antenna or antenna plug/cable damaged?
•
Is voice level too low or distance to microphone too far?
•
Does multipath effect occur? Change location.
•
In case of doubt, compare operation of the transceiver with that of another
transceiver FSG 5
/
FSG 5W at the same location.
•
Should the unit require service, contact your authorized dealer or service de-
partment.
