Text in single quotes indicate control titles.

Coaxial cable connections will be required between this transmitter and its matching receiver for BFO, Band and VFO signal sources so that transmission takes place on the same frequency as reception and the aerial changeover mechanism (T/R switch).

Control lines will also be required to mute the receiver and to control the T/R switch and to provide a signal to the anti-vox circuit.

The T/R switch is most conveniently placed close to but outside the PA enclosure.
