[ARC5] How Edwin Armstrong invented the superhet

[K2GKK D C_Mac_ Macdonald]

Regen detector operated just into the feedback mode.

My Novice receiver was the 6SN7GT dual
triode as detector and audio amp which
was part of the $50 Walter Ashe Novice
Station kits!

I had always assumed that;

1.  The TRF set is essentially a Superhet IF.
2.  The TRF has some major disadvantages for multiband sets, like the big clunky coils of my RU receiver 
3.  The TRF had to cost more to build than the Superhet, given that complex tuning mechanism.
4.  Hence the Superhet.

Now, since they used CW a great deal in those thrilling days of yesteryear, how did they receive it on a TRF set?
