Re ARC-38


 Just to again to confuse the issue------- there is the 618S-1/MC It
was made (so my manual says ) byRCA, looks outwardly like the  ARC-38A
, has some  similar modules, a different  tuning head  and
"channeliser". In essence  similar in operating  respects tho' using
SSB.
Unfortunately I  don't have one  as  I consider it  superior to the
ARC-38A technically .
 The manual I have is  T.O 12R2-4-6-32

I like the cold war gear too.  But we collectors need to be careful
with nomenclature.

The Collins commercial 618S-1 and the USN RT-311/ARC-38 are NOT the
same set at all.  The 618S is crystal-controlled.  The RT-311/ARC-38
uses a complex "stabilized master oscillator" to generate frequencies
at 0.5 or 1 kc intervals, depending on frequency.  Likewise, the
control heads are very different.  I don't know how the bad dope got
started that the AN/ARC-38 was the military version of the 618S.
