I missed your earlier post on this.
Which BC-229 and BC-230 do you have?
They should have names like "BC-AH-229."
I'll dig out my books and see if I can
come up with a sensitivity spec.
D.S.

I have two: a BC-AS-229 and a BC-AR-429. The AS is by Philco and the AR by
Western Electric. I have the manuals, but unlike other Signal Corps manuals,
there is nothing in them about sensitivity or adjustments.

Thanks.

Steve.
