[ARC5] [Milsurplus] BC-348 obscure trivia

[Joe Connor]

 Jack, that is very interesting. Perhaps it happened on other military sets, too. For example, I've been working on a Navy RAK and a Navy RAL. The sensitivity control on the former is audio taper but it's linear taper on the latter. It had me confused until I read your post, Jack.

 In poking around various BC-348s, I
have discovered that the MVC section
of the volume control has a linear
taper on some radios, and an audio
taper on others.

Problem with the linear taper is that
the large majority of the gain reduction
takes place in a very narrow range.

But, Murphy's law dictates, that this
very narrow range is where the "sweet
spot" for best CW and SSB reception
lies.

Anyone know the reason for the two
different types? When ordering
replacements, did someone forget
to specify audio taper?
