Noise interference Noise interference by
other equipment
Identify the source of interference by switching off other
equipment. If possible, move the transceiver and/or
antenna away from the noise source.
Inadequate earthing of
the transceiver
Improve the earth of the transceiver by connecting an
earthing strap (braid or copper strip) from the earth screw
of the transceiver to the earthing point, keeping the strap
as short as possible.
No power The internal fuse of
the transceiver has
blown
Replace the fuse.
