Page 104 FT-2000 OPERATING MANUAL
Packet operation is easily accomplished on the FT-2000 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.
PACKET OPERATION
PACKET SETUP
(
INCLUDING SUBCARRIER FREQUENCY
)
Before operation can commence,
some basic setup procedures must
be performed, using the Menu, to
configure your radio for the data
mode to be used.
BASIC SETUP
1. Press the
[
PKT
]
button.
ADVICE:
For HF operation, SSB-based Data operation is gen-
erally used. One press of the
[
PKT
]
button 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
]
button re-
peatedly to illuminate the ‘PKT” LED to orange,
to engage the “PKT-FM” mode.
When both the “PKT” and “USB” LEDs are illu-
minated, the FT-2000 has engaged Packet opera-
tion in the “USB” mode.
2. When the “transmit” command is received from the
TNC, the transmitter of the FT-2000 will automati-
cally be engaged. Likewise, the command to return to
receive will cause the radio to revert to the receive
mode.
ADVICE:
If you need to adjust the output level from the “DATA
OUT” pin of the PACKET jack (pin 4) on the radio,
please use Menu item “067 dAtA OUT LVL.” For the
input level from the TNC, as applied to the DATA IN
pin of the PACKET jack (pin 1), please do so at the
TNC side.
During Packet operation via the rear panel’s PACKET
jack, the front panel MIC jack is cut off, so you won’t
have a “live microphone” problem during data opera-
tion.
NOTE:
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.
