 RJT> Worse yet,  it wanted 400 cycles!

 Every ship I was on had both 60cps and 400cps systems.

 The biggest advantage of 400cps is the small filters
 after rectifying to D.C.   High freq = low microfarads.

 Carol's is a Senior Chief on a ship homeported in Japan.
 While she was here in San Diego, instructing at the Naval
 Training Center Service School Command, she was a Radioman
 First Class.  She made Chief while with the pre-commission
 crew of the John Stennis before going back to shore duty
 in Virginia during the time the RM rating was abolished.

 Carol is the ONE person who got me interested in being a
 sysop and the ONE person who helped the most is setting
 up Telegard and FrontDoor.
