[ARC5] [Milsurplus] AN/ARC-5 on MF 630 Meters

[MICHAEL ST ANGELO]

I finally found the paper that I was thinking about - "Homing Beacons, Instrument Landing System Markers, "Z" Markers, Fan Markers and Bone Markers" by Cletus W Whitaker WB2CPN who unfortunately passed away in 2019.

I was wrong on the equipment and application. The paper shows a pair of BC-610's  used as a homing beacon in Okinawa in 1968.

This exercise made me realize I have to go through by documentation and catalogue what I have before more brain cells go away.
