Well, I have late 1950s Hammarlund HQ170 whose S-meter works just  
fine with the AGC/AVC turned on or off. As far as I have been able to  
ascertain, the S-meter functions identically with or without the AGC/ 
AVC turned on. It was designed to do so. The QST review at the time  
commented on this feature.

So it is possible to build a receiver with an S-meter that functions  
with the AGC on or off. It was done nearly 50 years ago. I am not  
sure why receiver designers have not incorporated this useful feature  
into more modern rigs.

Now I am not a fan of AGC, in fact I think the most useful feature of  
a receiver with AGC is the ability to turn it off. :^)= - Dr.
