[ARC5] AN/ARC-5 support for CW

[Brian]

Hello Neil,

I think you need to specify to whose intention you refer. When Dr Drake was 
designing these sets in the early 1930s to assist the US post to get air 
mail through reliably, he probably had no idea of military intentions. It is 
so easy to slip from what we see to claiming that is what it ought to have 
been. Ain't necessarily so.

The source?
https://en.wikipedia.org/wiki/AN/ARC-5

Now admittedly, I rewrote some of the lead (intro) of that
article to make clear that the AN/ARC-5 could not do CW.
I did that on the basis of longstanding content elsewhere
in the article that said:

"The most common AN/ARC-5 receiver remote control box
is the C-38/ARC-5, which allows control only of audio volume
of the VHF and MF/HF receivers. No power, mode, or
frequency controls are present. The C-38 also has controls
for the R-4A homing receiver. A common AN/ARC-5
transmitter control box C-30A/ARC-5 has controls for
selecting the MF/HF transmitter or the VHF transmitter, and
a switch to select the channel for both the VHF transmitter
and receiver. Mode controls are normally set for voice and
covered."

It's obvious from that content that there was no intention to
provide CW capability, unless for some kind of dire
emergency where the plane was probably not in the air,
because the pilot would need to access the MD-7 modulator
to plug in a key, if he even carried one.

The above implies that the C-38 control box does not even
allow switching-on of the receiver's BFO.
