[ARC5] Answering Floyd's Question

[Jack Antonio]

In answer to Floyd's question on bench testing
command receivers, here is what I would suggest.

First, since Floyd was talking about control and audio,
I assume he already has power into the receiver.

I would use a stock FT-230, and leave the pot, switch
and audio connections external to the receiver, using
the 7 pin rear panel connector.

But that means finding the male plug for that connector.
The 7 pin plugs from the racks sometimes show up, but here
is an alternative.

If you have a beat up, unrestorable, unrepairable set, pry
an IF can plug out of the receiver chassis. It will fit the
rear panel connector. The only problem is that pin #7, or
center pin is missing.  This pin is B+.  If B+ is brought
into the dynamotor plug, or you are running the receiver off
the dynamotor, then this is no problem. You now
have all the handles for gain, CM/MCW, and audio.

It might be possible to add a center pin, by cannabalizing
another plug, then you could bring power and control on
one plug.

Actually, if B+ and filament are brought into the dynamotor
connector, then you wouldn't need anything
plugged into the front of the receiver.
