If that is indeed the case there must be a problem.

Yes, that could certainly be the case if the AGC were switched completely off.
That can be a good reception technique, but then of course the RF gain has to be
lowered.
But with the AGC on, the R7/A can handle most anything and should not be
experiencing blocking with the RF gain set completely clockwise.

Drake's R7,7A and TR7 have a VERY dynamic range . In 1979 WRTH
receiver review testing was done in the heart of Manhattan and NO
overload of any sort was observed. The front end is very well
designed and capable of handling extremely high signals. However,
I don't like to expose vintage equipment to the extremes, just a
precaution. AM (mediumwave) signal strengths here in NYC
are quite high , especially from WOR and WABC. We are talking of S
+60dB...
