Rich,
The common telescope is a device that is "bidirectional", i.e., it "processes"
light both ways, and either end can be used as receiver or transmitter.
"Audio telescopes" are more likely to operate electronically and are
thus "unidirectional," so you don't have the ability to reverse
input and output function.

Not true. Neither the receiver (compare with camera) nor the audio
source (compare with illumination) are part of the telescope.
You're right: "receiver" and "transmitter" were the wrong terms. Substitute
"input" and "output," respectively.
However, this was a terminology issue; the basic point was sound (no pun
intended).
