Before you unpack the repeater...

Take a minute to note how the unit
is packed. If you should ever need to
return the unit for service at some
time in the future, you must be able
to pack it properly. Should you ever
reship your repeater, you will need all
the packing material which came with
the unit. We recommend you find a
safe spot in your attic to store the
carton and padding.

Before you turn on power...

Don't change any control settings.
Don't adjust anything until you read
the rest of this instruction manual
and the OPERATION manual.
Note that shock and vibration in
shipping can cause problems when
any unit is first
Intermittent problems which may not
have been evident at the factory can
easily show up after bouncing around
for thousands of miles.
encounter any problems with your
unit, please call and we will get you
squared away promptly.
One problem which can happen is
that the compression mica variable
capacitors in the pa may change
settings due to vibration. We seal the
screws, but you may have to repeak
the capacitors for maximum output if
the power level is low.
Please check the VSWR of the an-
tenna system and the power output of
the transmitter before operating the
unit for any length of time.
can be damaged if operated in a
detuned or misloaded condition for
very long.
Note that it often is necessary to
retune the output capacitors (big mica
variables on vhf units) on the repeater
PA module to match the antenna
system you have. Repeaters are fussy
about being tuned properly to avoid
desense. We highly recommend you
repeak just the
capacitors, using a good wattmeter
in line with the transmitter output
cable. This is especially necessary
with the 25-30 output option on
two meter units because the PA
transistor has a lot of gain and can
oscillate if mistuned.
desense, it often helps to change the
length of the coax between the output
of the repeater and the duplexer.
