   I think I chatted with You about the 4-65 tubes I seen in a UHF rig when   
   I was in the Navy.   
   They were used in the Modulator section (I think it was a AN/GRC-39?),   
   too long ago....., I just remember the rig was called a ANGRY something.   
      
   I like the Specs for the 4-65 Tube.

   I'm not sure but I'd think that here in the U.S. a couple of wing nuts   
   would make it a easy job for a thief to steal that TR-3.   
      
   I just looked at what I said was the "Bolt(s)" Bruce and I used.   
      
   Each one is a 4 1/2 " long piece of 1/2 Inch Threaded Stock with a Nut   
   on one end of it and 2" of the other end is smooth - the threads have been   
   grounded off.   
      
   A small hole is drilled through the Nut for a Keeper Pin to keep the Nut on   
   the Threaded Stock to mount the TS-520S when I had it in the 1969 Buick,   
   years ago.   
      
   Bruce's idea made it a "little" harder for a thief to remove the XCVR.   
      
   Is thievery a problem where You live like it is in the U.S.?

   Even though I haven't keyed a rig for years, I love 20M CW too.
