Indeed. Mirek has done it correctly in my opinion.

By "the command receiver" do you mean a fixed frequency demodulator output for the IHU3?
Yes. A fixed frequency separate input not in the passband. I can hear James Miller in my head : "We shan't have the punters confiscating the command channel".
But if the punters are saturating the L Rx front end, the commanding cannot get through to the decoder.

Dick,
For this reason I totally separated IF chain for usesrs and for commands. The AGC influences only user's outputs. The command receiver contains own filter shifted to the passband and works as limiting.
