That's not quite what I said. I referred to "sophisticated
by 1940's standards". It had no bandswitching (to its
credit rather than detriment), no noise-limiter, no crystal
filter, a very noisy front end, and an AGC system that can
only be described as adequate.

If you ignore the fact that the SCR-274-N receiver was a
radical concept and neatly packaged and beautifully built
unit, you end up with a receiver which, apart from the
addition of a BFO, was no more sophisticated than a
6-tube household receiver of the time.

I love those receivers, but they were really just a basic
6-tube superhet.
