The outputs are configured on the Outputs tab. All three types of output are
used.
The ANT class is appropriate for the antenna switch, 80m dipole relay and
both 4SQ controls because these outputs must be set to select a specific
antenna.
Band pass filters have to be activated when the operating frequency is
within selected filter pass band regardless of which antenna is selected. To
accomplish this the filters must be controlled with BPF class outputs.
The preamplifier in the receive four square must be turned off during while
transmitting and when operating on bands above 40m. To do this, the
preamplifer power should be controlled by a SEQ output.

Once output classes have been determined, specific outputs can be assigned on ANTENNAS TAB.
