Packet operation is easily accomplished on the FT
DX
9000MP by connecting your TNC (Terminal Node Controller) to
the transceiver, per the illustration. “Packet” operation also applies to SSB-based AFSK data modes, such as PSK31, etc.

Before operation can commence, some basic setup proce-
dures must be performed, using the Menu, to configure
your radio for the data mode to be used.
1. Press the [ PKT
] Mode switch.
For HF operation, SSB-based Data operation is
generally used. One press of the [
PKT
] switch will
engage Packet operation in the “LSB” mode (by
default). Both the “PKT” and “LSB” LEDs will
become illuminated.
If you need to do FM-based 1200-baud packet on
the 29/50 MHz bands, press the [
PKT
] switch once
more to engage the “PKT-FM” mode. the “PKT”
and “FM” LEDs will both become illuminated.
2. When the “transmit” command is received from the
TNC, the transmitter of the FT
DX
9000MP will auto-
matically be engaged. Likewise, the command to re-
turn to receive will cause the radio to revert to the
receive mode.
If you need to adjust the output level from the ra-
dio from the “DATA OUT” pin of the [
PACKET
]
jack (pin 4), please do so at the TNC side. For the
input level from the TNC, as applied to the DATA
IN pin of the [
PACKET
] jack (pin 1), please use
Menu item “ MODE-PKT 071 PKT GAIN ”.
During Packet operation via the rear panel’s
[
PACKET
] jack, the front and rear panel MIC
jacks are both cut off, so you won’t have a “live
microphone” problem during data operation.

If you anticipate making data transmissions of
longer than a few minutes, we recommend that you
use the [
RF PWR ] control to reduce the transmit-
ter power to 1/2 ~ 1/3 of its normal maximum.
