That is a lot of help.  Folks, those are the control boxes for the
NRL-ordered crystal controlled ARA receivers.  There were only 600
receivers and 300 transmitters (or the other way around - perhaps
Gordon can correct me here) ordered and thisd is the rexeiver CB for
that order.  This was why the stabilized ARC-5 receivers came into
being; A.R.C. told the Navy "We can fix this our way" and they did.
