    • Well, Google's 'advertising optimization' has now become so distracting as to trick people into visiting other sites. So I have removed advertising until I can find a better solution. One option may be sponsorship, anyone interested?
  • Sponsorship!
    • We are very graitful to Neill, who supports BAMA in gratitute with his financial support
      • It's free to use, but every little amount helps keep it that way!

NRL Report R-1840 23 Jan 1942.pdf:
The graphs of selectivity etc which are in color, are particularly
interesting.  It was also interesting that Hallicrafters did not
follow many of the NRL’s recommendations from this report.

Note that the S-27C was the earlier version of the S-37. The
S-27 (non-C) was the predecessor of the S-36 and S-36A.
