Used in all-band doubleconversion superheterodyne receiver for AM,narrow-band FM, CW, and SSB operation. Input is fed through 455-kHz ceramic filter to highgain amplifier using three MPS 2926 transistors all having automatic gain control and master gain control. Use of silicon rectifiers in interstage networks of IF amplifier gives economical wide-range AGC circuit Supρlγ;is13.6 V regulated Article gives all circuits of receiver．－DM.Eisenberg,Build This All-Band VHF Receiver,73 Magazine,Jan 1975,p 105－112.
