Hi Tom!   
      
   As you posted ...   
      
    TW> That is true. Except in energancies we maintained radio silence when   
    TW> on partol. And receptionof traffic was VLF. The subs used a   
    TW> floating wire antenna that could be trailed out of the rear of the sail   
    TW> structure. It was retracted when no needed. Transmissions were on HF and   
    TW> there was a retractable, like  Periscope, antenna that was used at   
    TW> periscope depth.   
    TW> In my day they experimented with burst transmissions. I am sure in this   
    TW> computer they are a little more hi tech but in my day they used a reel

    TW> tape with cue marks for triggering the transmitter. The tape deck was   
    TW> run at FAST forward speed and sent the message   
      
   Bet this will be also fascinating to you!  My cousin Bobby Dunkin was an   
   original telecom expert back in even the end of WWII into the 50's.  As a kid   
   my Dad forbid us from even having a television set where I grew up in College   
   Station, Texas until one of my uncles, Bill Schuster, who was actually part of   
   the creation of the original Emerson operation and at that time the largest   
   competitor to Allied Radio -forced us- to have a TV set in my parents home   
   here so Dad could watch Armstrong set foot on the moon!  I watched that TV   
   with my Dad and Mother for that episode here in the now Historic House.  As   
   fact, that black and white TV set has been donated to the Children's Museum in   
   Bryan, Texas for their exhibition of how TV came to here over uears and years.   
      
   As for my first TV view ever, it was up in Erie, Pennsylvania on WICU-TV where   
   Bobby was creating this stuff.  My first TV ever seen was actually on a   
   Hallicrafters 7-inch black and white relay rack TV set in my Uncle Bobby's   
   house there during our 'normal' visit to Erie every summer. Leap forward!   
      
   Bobby wound up as part of the engineering operation and was involved in the   
   VLF naval communication design for submarines at sea.  He was a part of the   
   design team for the antenna system which was used to punch the VLF signals   
   into the Pacific ocean for I think exactly what you are talking about.  He   
   eventually retired from his job up in the Dallas, Texas area long ago. Passed   
   away a number of years ago.
