Most FM receivers do not even have AGC since limiting is necessary. I do remember a few tube-type receivers that had some AGC applied to the RF amplifier (like the Motorola "SENSICON"). Why try to eliminate the squelch tail anyway? It does serve as an audible "over" signal. My only objection is to real long tails such as in a receiver with a very loosely adjusted squelch. Bob K9EUI
