[ARC5] R-24/ARC-5 - Yet Another Mysterious Function

[Robert Eleazer]

In the B-29 Combat Manual I have they mention that a certain number of B-29's were equipped with the optional low Freq (O-16 and O-17?) oscillators so that they could transmit signals that could be picked up by ADF receivers carried in all of the aircraft.  This enabled some aircraft to serve as beacons for rendezvous purposes.

Like Mike Morrow, I have wondered for some time why the ART-13 would need that LF capability.  This is one explanation and might be one reason the ARC-5 MF sets were built.
