My AGC uses 3 simple PIN diode shunt attenuators. An 0.1 cap connects to the circuit board and an MPN3404 goes to ground. The attachments points I used are the connections between R27/R105, R47/C30 and R17/C216. An AGC voltage derived from the audio or a manual "RF gain" voltage derived from RX both work fine.
