The
VX-8DR
may be used for Packet operation, using the optional
CT-M11
MIC/SP
Connection Cable (available from your Yaesu dealer) for easy interconnection to com-
monly-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
key, as with voice operation. The input level to the
VX-8DR
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, to prevent volt-
age spikes from damaging your transceiver.
