The
VX-150
may be used for Packet operation, using the optional
CT-44
microphone
adapter (available from your Yaesu dealer) for easy interconnection to commonly-avail-
able connectors 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
VOL
knob, as
with voice operation. The input level to the
VX-150
from the TNC should be adjusted at
the TNC side; the optimum input voltage is approximately 5 mV at 2 k-ohm.
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 operating a packet, you make battery saving “OFF”.
