ACOM 700S will operate normally with KEY OUT unconnected if your transceiver has no
such input.
Transceiver producers give different names to this input and they are for instance
TX-INHIBIT, MUTE, LINEAR, etc. Check your transceiver's manual.
d) RF INPUT connector
Connect a suitable coaxial cable from the transceiver output to the amplifier RF INPUT SO-239 connector
(see Figure 2-4 | Rear panel - Connections, Pos. (d)), using PL-259 plug.
NOTICE
In order to avoid a damage, turn off your transceiver's internal antenna tuner.
e) RF OUTPUT connector
NOTICE
If this is the first time you will use a power amplifier in your station, pay attention to the
coaxial cable type from the amplifier's output to the antenna. It must handle the
increased power safely, particularly on the 10- and 6 meters bands. We recommend that
you use RG213 cable or better. Check the same for the antenna switch and tuner, as
well as the whole antenna system (especially multi-band trap antennas).
Connect a suitable coaxial cable with a PL-259 plug from the RF OUTPUT (see Figure 2-4 | Rear panel -
Connections, Pos. (e)) to the antenna switch or tuner, or to antenna for the respective frequency band.
The ACOM 04AT and 06AT automatic antenna tuners with four-way antenna switches are
designed to work with our transistor (solid state) amplifier series, including the ACOM
700S (see Section 4.3 Operation with an External Antenna Tuner).
Using the ACOM 06AT or 04AT with an ACOM 700S amplifier is highly recommended.
We recommend coordinating, with ACOM, the use of non-ACOM antenna tuners for
connection to RF OUTPUT.
ACOM, as an Original Equipment Manufacturer, keeps the right to refuse the guarantee
claims if non-suitable equipment is used.
