[Milsurplus] ARC-4 Xtal Frequencies.

[Telegrapher at att.net]

Happened to be cleaning out my email in the old Netscape mailbox and ran across an email sent by Dave S. back in November of '05 pertaining to a web page:

http://www.ibiblio.org/hyperwar/USN/rep/Leyte/OpPlan/13-44-N.html

I see that the ARC-4 crystal frequencies  in the VHF region (of course) were used as follows, at least in the Pacific.

Air-Sea Rescue (S)	140.58	MCSFighter Direction-Objective Area & during approach (FD-OA)	142.02	MCSFighter Direction-Emergency Objective Area (FD-E-OA)	142.74	MCS
No mention of 142.560 though.


That document as well as the others in the index are indeed great reading.

This posting has no value other than a refresher for those who's memory may have slipped a nothc!

PS:  Did ship radio calls ever change?  If so, how often and when?
