[ARC5] RU-18

[Mike Morrow]

>Yesterday I was offered an "RU-18 w/coils and remote box", maybe dyno included. 

The dynamotor unit is the CW-21215A.  The junction box is the CW-62007A.  Try to get those units, if possible.

>...understand that it is an ARC-5 predecessor?

Well, it would be used with a large GO- or GP-series transmitter, so it's very different from the ARA/ATA series, which is the real predecessor to the AN/ARC-5.

The RU/GF-series could be considered the predecessor to the ARA/ATA.  But the plug-in coil, TRF-design of the RU-series is a very different and older design than the ARA.

The Navy RU/GF-series bear much visual similarity to the contemporary Army SCR-183/283 series, but there are many major electrical differences between the Navy and Army sets, especially the later versions.
