Using the above information, an appropriate cable for your transceiver(s) may be
constructed, or you might wish to order a correctly made-up cable when you order your
amplifier from your local dealer. The amplifier connector is included with the
amplifier,and the transceiver connector (called “Radio” in the next diagram) is usually
supplied with the transceiver.
For connections to the Radio connector, refer to the transceiver operating manual.

In the case of SPE transceivers, it isn’t necessary to make a cable because it is
supplied with the transceiver.
