I spent some time in three different RU/GF manuals trying to
understand the opinion expressed below in blue, and could not find a
single reference to two preset transmitter coil positions on
any of the GF TX coil sets, nor any switch identified to accomplish
such a capability. Such switches were installed in dual
frequency receiver coil boxes, but not in the
transmitter coil boxes. Changing frequency with the set isn't a
trivial proposition, even if approximate settings have been penciled
on the data plate for a given coil box, as shown in the
instructions:
I think we all would appreciate clarification with a bit more
detail.

If the aircraft was equipped with the remote switches for the coil

frequencies on bothe the receiver and the transmitter to the two
preset frequencies the coil was set to on the transmitter,
and the two frequency bands the receiver was set up for ( the
receiver could also be fine tuned using the “ coffee grinder”
tuner the pilot had available to him. The ZB Homing adapter had to
be turned on via the pilots control box in order for the receiver
to be used for navigation. If the ZB was not engaged, the lower
receiver frequency could most certainly be used for regular voice
or CW communications.
