Timewave PK-900, Operating Manual, Page: 33 / 392

3.3.3 Check Your Transceiver's Operating Manual
Locate the Operating Manual for your transceiver and turn to the page
describing the connector to which you will attach your PK-900. Even
if you found the exact model of your transceiver in APPENDIX E, it is
a good idea to verify that your transceiver's manual agrees with the
information in the appendix. If the information does not agree, or
you could not find the exact transceiver model in APPENDIX E, then you
should use the information contained in your transceiver's manual to
connect the PK-900.
3.3.4 Specific Connection Points
Whether you are connecting an HF Single Side Band transceiver for
RTTY/FAX operation, or a VHF/UHF transceiver exclusively for packet,
the minimum connections to your transceiver will be almost identical.
HF transceivers have a few optional connections that will be covered
after the basic connections have been made.
The following table and figure will be helpful in identifying the
proper basic connection points to the PK-900 radio cable.
