Vertex Standard FT-1000MP ユーザーズマニュアル

This is a 3.5 mm miniature stereo phone jack which

provides constant-level (100 mV @ 600 

Ω

) for con-

nection to a WeatherFax decoder, tape recorder, or
other accessory. The audio output level is not affected
by the setting of the front panel AF GAIN & SUB AF
controls, so you can turn the volume down, if you like,
without affecting the audio level being presented to your
decoding device. The tip connection of this jack is Main
receiver audio, while the ring connection is Sub receiver
audio.

The connections to the AF OUT jack are at the same

level as the connection to Pin 4 of the PACKET jack.
However, the two output ports use independent output
buffer amplifiers, so you can freely connect and dis-
connect devices to/from these ports without concern
over the impedances and levels.

This RCA jack is wired in parallel with the front

panel’s MIC jack, providing a handy connection point
for a  footswitch for voice operation, allowing hands-
free PTT operation.

For transmit audio input for SSTV (Slow-Scan Tele-

vision) operation, you may connect the SSTV terminal’s
T

UDIO

 line to the PATCH jack. You will need to dis-

connect the microphone, however, during transmission,
as the PATCH jack is connected in a “Y” configuration
along with the microphone input (from pin 8 of the MIC
jack).

The MARK-V FT-1000MP includes a host of fea-

tures for the CW operator, the functions of which will
be detailed in the “Operation” section later. Besides
the built-in Electronic Keyer, two key jacks are provided,
one each on the front and rear panels, for convenient
connection to keying devices.

Both KEY jacks on the MARK-V FT-1000MP utilize

“positive” keying voltage. Key-up voltage is approxi-
mately +5V DC, and key-down current is approximately
0.5 mA. When connecting a key or other device to the
KEY jacks, use only a 3-pin (“stereo”) ¼” phone plug;
a 2-pin plug will place a short between the ring and
(grounded) shaft of the plug, resulting in a constant
“key-down” condition in some circumstances.

1. For everyday operation using the internal electronic

memory keyer, connect your paddle to the front
panel KEY jack, and activate the front panel [KEY]
switch. If you wish to keep the keyer paddle’s cable
out of the way, connect the plug, instead, to the rear
panel KEY jack.

2. If two operators are using the MARK-V FT-1000MP

simultaneously (for a contest, Field Day, etc.), a
second keyer paddle may be connected to the rear
panel  KEY jack. With the front panel  [KEYER]
switch pressed in, both operators’ paddles will have
access to the internal keyer.

3. If two operators are using the MARK-V FT-1000MP

simultaneously, but both wish to use a straight key,
outboard electronic keyer, or computer-driven key-
ing cables, the key plugs may be inserted into the
front and rear panel KEY jacks; now turn the front
panel’s [KEYER] switch off.
