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.
Menu Item Available Values
050 DATA DT GAIN 0 ~ 100
051 DATA OUT LVL 0 ~ 100
052 DATA VOX DLY 30 ~ 3000 ms
053 DATA V GAIN 0 ~ 100
054 DATA PKTDISP –3000 ~ 3000 Hz
056 DATA PKT SFT –3000 ~ 3000 Hz
Basic Setup
1. Press the [RTTY/PKT] button repeatedly to select desired Packet mode. By
pressing the [RTTY/PKT] button to mode changes:
PKT-LSB  PKT-USB  PKT-FM  RTTY-LSB  RTTY-USB  PKT-LSB …
Advice:
 For HF operation, SSB-based Data operation is generally used. Press the
[RTTY/PKT] button repeatedly until the “PKT” and “LSB” icons will appear on
the display.
 If you need to do FM-based 1200-baud packet on the 29/50 MHz bands, press
the [RTTY/PKT] button repeatedly until the “PKT” and “FM” icons will appear
on the display, to engage the “PKT-FM” mode.
 When both the “PKT” and “USB” icons are appeared on the display, the FT-950
has engaged Packet operation in the “USB” mode.
2. When the “transmit” command is received from the TNC, the transmitter of the
FT-950 will automatically 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 (pin 5) of the
RTTY/PKT jack on the rear panel of the transceiver, please use Menu item “051
DATA OUT LVL”. For the input level from the TNC, as applied to the DATA IN pin
(pin 1) of the RTTY/PKT jack, please use Menu item “050 DATA DT GAIN”.
 During Packet operation via the rear panel’s RTTY/PKT jack, the front panel MIC
jack is cut off, so you won’t have a “live microphone” problem during data
operation.
