Re: Installing BCI and Kit-Projects AGC
Jerry Gaffke
The AGC board operates on two different signals in the radio.

AGC attenuation level is determined by measuring the audio signal level after all of the filters that pick out only your signal of interest. The AGC board is physically placed in the incoming RF path (not in the audio section) so it can best attenuate the very low level signal coming in from the antenna. You might be right that the BCI filter would be better placed in front of the AGC board, this could help if incoming AM broadcast band signals are 10 times stronger than all the shortwave signals. But if the AGC board's RF attenuator is sufficiently linear, it won't make any difference. I don't see any advantage in having the BCI filter after the AGC attenuator. Jerry, KE7ER
