        I always forget something. I don't remember
      where I found the manual I have but I will post it to the list or
      to the list archives if desired. Again, it is TM 11-300

        Hello,
        I follow your forum and thought I would
            mention that I do have a TM on BC-221 sets, not
        sure which one it was written for, I could
            probably find it if it would help someone. I have
        two BC-221, I think one is in a canvas case,
            both are in storage and I am going over
        there tomorrow.

             Somewhere I found a military TM that covers
                all of the BC-221 meters. Noton BAMA and I can't find
                it. It may help because at least it would tell you what
                differences are between them.  I have a BC-221, a late
                one with factory power supply. I have to look to see
                which version it is.  Its in a wooden case which makes
                setting the crystal calibrator difficult since it drifts
                a little with temperature and I don't want to drill a
                hole in the case. It is quite accurate once warmed up.

                  I
                    guess the time has come for me to keep one of these
                    in the shack. I have had literally dozens of them go
                    through my hands over the years. Now I have two here
                    and one of them is going to stay. But which one? The
                    J model is in lesser condition. The T model is
                    almost like new. Both have AC supplies in them--the
                    one in the T model might be a factory supply. The
                    one in the J model is almost certainly homebrew.
                    Both have the spare tubes and hex wrench where they
                    ought to be. Both have the correct calibration
                    books. Both were made by Zenith. 
                  

                  
                  Is
                    there any reason to prefer one over the other except
                    overall condition? I have not tested them yet. But
                    it does not seem like they would be hard to get
                    running. Is there an achilles heel in them that I
                    should check?
                  

                  
                  Any suggestions welcome.
