[Milsurplus] PBY-5A ATD/ARB photo?

[Hubert Miller]

This may already be well known to this discussion, but….one of the old CQ magazine articles, probably around 1960 – 1963 era, showed the tail area inside. As I recall,
only an ARB and some Command receivers were visible, no other transmitter. At the time I read the article, it was pre-internet, and I puzzled over what kind of an
aircraft the BTD-1 was. 

Thanks for the SOC3 reference. I think that gives the stamp of plausible authenticity to anyone's ATD / ARB setup.

This is the only aircraft that in my simple mind might have initially received the ATD...all 39 of them...:-)
