Packet Operation - Yaesu FTDX9000D - DATA MANAGEMENT Operation Manual

P O
ACKET PERATION
Packet operation is easily accomplished on the FT
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
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.
