(AFSK):
carries
the transmit audio
signal from the PK-96
to
your
transceiver fbr
transmission.

an electrical return-path
fbr the PK-96's DC

Connections for
Specific Transceivers
Appendix
A contains notes
and diagrams fbr
connecting the PK-96 to
many VHFruHF transceivers lbr
1200
bps operation.
Go there
to
locate
the transceiver model(s)
you
will be connecting
to
your
PK-96. At
the same time, refer
to
your
radio's
Operating Manual
to
verify
the
pin
assignments.
(If
you
don't find
your

in Appendix
A, then locate a model from
the same manufacturer that has
the same acces-
sory
or
mike
connector
and
pinouts
as
the
unit
you'll
be connecting-usually
the manufacturer is consis-
tent with
their wiring fbrmats
so the hookups will
be the same.)
For radio hookups
involving
9600 bps operation, see
