RTV
DIN Jack
This 4-pin inpueloutput jack provides connec-
tions for an RTTY terminal unit. Pinout is shown
on pages 4 and 53. The receiver audio level at this
jack is at a constant 100-mV (@ 600 St) level.
(10)
PTT
Phono Jack
This input jack may be used to control manual
transmitter activation using a footswitch or other
switching device. Its function is identical to the
MOX
button on the front panel. The same line is
available at the
PACKET
and
RTTY
jacks for TNC
control. Open-circuit voltage is +13.5 VDC, and
closed-circuit current is 1.5 mA.
(1 1)
EXT ALC
Phono Jack
This input jack accepts external ALC (Automat-
ic Level Control) voltage from a linear amplifier, to
prevent over-excitation by the transceiver. Ac-
ceptable input voltage range is 0 to -4 VDC.
(12)
PATCH
Phono Jack
This input jack accepts transmitter audio
-
either AFSK or voice, for transmission. This line is
mixed with the microphone audio input line, so the
microphone should be disconnected if using this
jack and mixing is not desired. lmpedance is 500
- 600 St.
(1 3)
EXT SPKR
Mini Phone Jack
This 2-contact output jack provides mixed re-
ceiver audio for an external loudspeaker, such as
the SP-8. Inserting a plug into this jack disables
the internal loudspeaker. lmpedance is 4 to 8
a.
(1 4)
AF OUT
Mini Phone Jack
This 3-contact jack provides dual-channel low
level receiver output, for recording or external
amplification. Peak signal level is 200 mVrms at
600 St. Main receiver audio is on the left channel
(tip), and sub receiver audio is on the right chan-
nel (ring). A stereo amplifier or recorder is recom-
mended, to record each receiver separately when
dual reception is enabled. The front panel
AF
GAlN
control and the
AF REV
switch setting do not
affect the signals at this jack.

GND
Terminal Post
Use this terminal to connect the transceiver to
a good earth ground, for safety and optimum
performance. Use a large diameter, short braided
cable.

BAND DATA
DIN Jack
This 8-pin output jack provides control signals
for the FL-7000 Solid-State Linear Amplifier or
FC-1080 Remote Controlled Antenna Tuner, in-
cluding band selection data to automatically set
the Linear or Tuner to the same band as the main
display of the transceiver. Band Data jack connec-
tions are shown on pages 4 and 68.

+ 1 3 . 5 ~
Phono Jack
This output jack provides regulated, separately
fused 13.5 VDC at up to 200 mA, to power an
external device such as a packet TNC. Make sure
your device does not require more current (if it
does, use a separate power source). Attempting
to draw more power from here will blow the inter-
nal fuse behind this jack. Should this occur, re-
place the fuse as explained on page 101.
(1 8)
RX ANT
Phono Jack
This antenna jack is for a separate receive-
only antenna, activated when the switch with the
same name on the front panel is pressed. An
antenna connected here can be used by both the
Main and Sub Receivers.
(1 9)
TRV
Transverter Drive Output Jack
This jack provides a low level RF output for use
with a transverter. Output is approximately 100
mVrms at 50
St.
(20)
TX GND
Phono Jack (normally disabled)
When enabled by the
LIN
switch, this output
jack connects inside the FT-IOOOMP to a set of
relay contacts which short together (to chassis
ground) whenever the transmitter is active. This
allows transmielreceive switching of an external
device such as a linear amplifier. This jack is
disabled at the factory to avoid the clicking of the
relay when it is not used.
(21)
LIN
Linear Amplifier Relay Switch
To enable the
TX GND
jack and RX front-end
protection when you are connecting a external
linear amplifier, move this switch to its
ON
position.
Maximum ratings for these relay contacts are
500 mA @ 125 VAC, 300 mA @ 220 VDC or 2 A
@ 30 VDC. Before connecting an external device,
make sure its switching requirements M/ill not ex-
ceed these limits.
If your amplifier requires higher current, or has
higher voltage switching requirements, an exter-
nal switching device must be used.
