Can't be sure of the details without looking at the diagram (too lazy 
right now ...) but in general putting AGC on a mixer causes the 
load reflected to the local oscillator to vary with signal strength and 
since the HBR-series does not use a L.O. buffer (right?) you'd wind 
up with a receiver that changed tuning appreciably with SS.

All talk, no action in the HBR department for the last year.
