[ARC5] AN/APX-1

[elden meyer]

The APX-1 and APX-2 share the same upper chassis,
thus the peripherals on that chassis have APX-1
designators. The lower chassis determines the
system and carries the overall nomenclature plate.

The RT-22/APX-1 is a basic transponder (i.e. replies
to interrogation) and operates from 24 DC. It is
similar in function to units like the BC-966 and
has similar (British ?)connectors.

The RT-24/APX-2, which operates mostly from 115 AC,
has additional RF circuits in the lower chassis
to allow operation as an interrogator-responser
(i.e. it can issue pulses for others to respond to).

There are brief descriptions of both these equipments
on-line in various equipment directory publications.
I have a copy of these to send to anyone interested.
If anyone has more than that I would also be interested.
