Less noise, for one (a BIG one).

Back when I was either given or traded-for an essentially new BC-779 
(which was given to me apparently because it had essentially NO BFO 
injection), I used the 6N7 noise limiter tube to build a triode 
product-detector which I copied from Heathkit's SB-100 in it and 
connected that in place of the diode detector.

BOY! What a completely amazing difference!!!!! :-)

I was completely amazed at the quietness, apparent sensitivity, and 
generally sweet, sweet recovered audio, and the detector seemed to 
work as well, or better, for AM as it did for CW/RTTY/SSB.

That double-preselection on ALL bands was a real winner as far as I 
was concerned.

I don't remember ever turning that receiver off after that for a 
number of years. On 20 meters, when listening to a weak CW signal, I 
noticed a very slight drift back-and-forth, probably 10 cycles or a 
bit more, perhaps. It gave those signals a very pleasing sound.

I used that receiver for RTTY on 20 meters also.

In fact, at one time I operated an 80 meter to 20 meter RTTY repeater 
for handling traffic.
