The
VX-8GR/GE
may be used for Packet operation, using the optional
CT-44
Micro-
phone Adapter (available from your Yaesu dealer) for easy interconnection to commonly-
available connectors wired to your TNC.
The audio level from the receiver to the TNC may be adjusted by rotating the
DIAL
knob
while pressing and holding the
g
key, as with voice operation. The input level to the
VX-8GR/GE
from the TNC should be adjusted at the TNC side; the optimum input volt-
age is approximately 5 mV at 2000 Ohms.
Be sure to turn the transceiver and TNC off before connecting the cables, to prevent volt-
age spikes from damaging your transceiver.
