The FT-847 may easily be configured for 1200 or 9600 bps packet operation.
Refer to page 17, and connect your TNC (Termi-
nal Node Controller) to the rear panel's PKT jack,
per the instructions on that page.
Set the FT-847 to the desired band, and press the
[FM/AM] mode key, as necessary, to select the
"FM" operating mode. Note that there is no
"Packet" mode activated via the front panel; the
"Packet" mode is recognized when the micropro-
cessor detects PTT control commands sent via the
Select the desired baud rate for your packet operat-
ing session. To do this:
l Press the [MENU] button to activate the Menu
mode of operation.
l Rotate the SUB-TUNE knob to select Menu #23
l Rotate the MEM/VFO CH knob to select either
"1200" or "9600" bps.
l Press the [MENU] key to exit the Menu mode.
If 9600 bps has been selected, the "9 6 0 0 " icon
will appear along the bottom edge of the LCD.
Note: For 2400 bps operation, you may have to
experiment with this Menu selection, as dif-
ferent TNCs may work better with one set-
ting or the other.
Note: The baud rate setting may be independently set
Set the transceiver to the desired operating fre-
quency. You may find it more convenient to use
the MEM/VFO CH knob to set the frequency in
the FM mode, because of the channelized nature
of most packet systems. Be sure to disable any re-
peater shifts, if they have been manually activated
Set the MIC (G
) control fully counter-clockwise.
Set the RF PWR control to the 12 o'clock position.
Using the keyboard of the computer connected to
your TNC, you may now issue the "Connect" com-
mand, and begin operation. When you transmit via
the PKT jack, the "DATA" icon will appear on the
Adjust the setting of the RF PWR control to the
minimum setting which will allow reliable com-
munication with the packet network on which you
are operating. Because of the high duty cycle which
may be associated with active packet networks, we
recommend that the RF PWR control be set so that
the power output is between15 and 25 Watts (144/
430 MHz) or between 35 and 50 Watts (50 MHz).
on each band and on each VFO. That is, you
may set the baud rate on VFO-A's 430 MHz band
to 9600 bps, while setting VFO-B's 430 MHz
band to 1200 bps. The baud rate setting will be
preserved if the frequency is stored into a
memory channel register.
