performance and range. An external antenna will allow the signal to be transmitted more
effectively. Target antenna locations include plastic rear panels and bumpers, or underneath
the vehicle.
Antenna location is the most influential factor in extending range.
5. Squelch Adjustment:
• Make sure the transmitter to be "REPEATED" is not turned on. Turn the
squelch adjustment counterclockwise until the transmitter is turned on (This will
have to be monitored with an additional receiver). Now turn the squelch
adjustment clockwise until the repeater transmitter is just turned off. Once
adjusted, turn the transmitter on and off, while monitoring the repeaters output
frequency. The repeater transmitter should switch on and off, along with the
transmitter being repeated
.
6. Bandwidth Switch:
• This switch allows the repeater to selectively RECEIVE either narrowband 12.5
kHz (NTIA compliant) or 25 kHz transmissions. Note that the repeater transmits
strictly in 12.5 kHz bandwidth mode, whatever the input bandwidth
.
As with all Wideband/Narrowband switchable devices, if the bandwidth switch is
mistakenly set for 12.5 kHz when a conventional wideband (25 kHz) signal is received,
audio distortion may result on the repeated channel.
