[ARC5] Seeking Information: Article on the original ARC commercial Type D receiver

[Mike Morrow]

Hello all.

Several years ago there was circulating from some radio site, IIRC, an article about the original battery-powered A.R.C. Type D aircraft receiver.  I believe it appeared in print sometime between 1929 and 1931.  I once had a hard copy, which I've misplaced.  I initially thought it came from QST, but I'm doubting that now because a lot of very painful QST archive searching at arrl.org has revealed nothing.

Does anyone recall this article, and know more precise details?  If so, is it on the web somewhere?  I have spent hours looking for it on the web since November and have now given up.

I come up completely empty when I search for anything related to A.R.C. Type D or any other similar search variation.  The Type D was the basis for ARC's SCR-A*-183 and RU-* receivers,.

Thanks.
