The
VX-2R
may be used for Packet operation, using the optional
CT-91
microphone adapter
(available from your Yaesu dealer) for easy interconnection to commonly-available con-
nectors wired to your TNC. You may also build your own cable, using a four-conductor
miniature phone plug, per the diagram below.
The audio level from the receiver to the TNC may be adjusted by using the
VOLUME
knob, as with voice operation. The input level to the
VX-2R
from the TNC should be
adjusted at the TNC side; the optimum input voltage is approximately 5 mV at 2000 Ohms.
Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent
voltage spikes from possibly damaging your transceiver.
When you are operating on Packet, switch the Receive Battery Saver OFF, as the “sleep”
cycle may “collide” with the beginning of an incoming Packet transmission, causing
your TNC not to receive the full data burst. See page 32 for details regarding Battery
Saver setup.
