Packet operation is easily accomplished on the
FT
DX
5000
by connecting your TNC (Terminal Node Controller) to the
transceiver, as in the illustration. “Packet” operation also applies to SSB-based AFSK data modes, such as PSK31, etc.

Before operation can com-
mence, some basic setup proce-
dures must be performed, using
the Menu, to configure your ra-
dio for the desired data mode.

1. Press the [
PKT
] button.
A
DVICE
:
For HF operation, SSB-based data operation is gen-
erally used. One brief press of the [
PKT
] button
will engage packet operation in the “LSB” mode
(by default). Both the “
” and “
” icons
will appear in the display.
To operate FM-based 1200-baud packet on the 29/
50 MHz bands, press the [
PKT
] button repeatedly
to illuminate the “
” and “
” icons, to en-
gage the “PKT-FM” mode.
To engaged Packet operation in the “USB” mode,
repeat pressing the [
PKT
] button until both the
“
” and “
” icons are appear.
2. When the “transmit” command is received from the
TNC, the
FT
DX
5000
transmitter will automatically be
engaged. Likewise, the command to return to receive
will cause the radio to revert to the receive mode.
A
DVICE
:
If you need to adjust the output level from the “DATA
OUT” pin of the
PACKET
jack (pin 4) on the radio,
use Menu item “
072 DATA OUT LVL
”. For the input
level from the TNC, as applied to the DATA IN pin of
the
PACKET
jack (pin 1), use Menu item “
070 DATA
DT GAIN
”.
During Packet operation via the rear panel
PACKET
jack, the front panel
MIC
jack is cut off, so you won’t
have a “live microphone” problem during data opera-
tion.
N
OTE
:
If you anticipate making data transmissions of longer than
a few minutes, we recommend that you use the [
RF PWR
]
knob to reduce the transmitter power to 1/3 ~ 1/2 of its
normal maximum.
