NOTE: If your RCV LED does not go out when you turn the squelch control clockwise, you will
need to set the CD command to SOFTWARE. This may occur when receive audio is taken from the
microphone connector or from a dedicated data jack.
Adjusting Transmit Drive Level
The drive level from the KPC-9612 to your radio can be ad-
justed by using potentiometer R22 and jumper J5. When J5
is placed on both posts, the drive may be adjusted through
the high range (140 mV to 4 Vp-p) with R22. Placing J5 on
one post only selects the low range (2 mV to 60 mVp-p).
This jumper is set at the factory for the low range, which
provides the proper drive level to most radios. If your radio
requires a higher drive, move J5 and adjust R22. See the di-
agram at right for the location of these components. You
should adjust the drive level to provide about 3 to 3.5 kHz
deviation with your radio. If you don't have access to a de-
viation meter, adjust this so your packet transmissions
sound about the same volume as most of the others you
hear.
