When 2 to 13.8 V is applied to pin 6 of [ACC 2], the [X-
VERTER] connector is activated for transverter opera-
tion and the antenna connectors do not receive or
transmit any signals. (p. 4-6)
While receiving, [X-VERTER] connector can be acti-
vated as an input terminal from an external transverter.
While transmitting, the [X-VERTER] connector outputs
signals of the displayed frequency at –20 dBm (22 mV)
as signals for the external transverter.
To connect a TNC or scan converter, etc., refer to the
diagram below.
