AGC (wide AGC input connected to RFT primary through 10pF and 1K
Ω)
IF Amplifier 1 (Input at FMIFAMP1IN, fc = 10.7MHz, no mod) (Output at FMIFAMP1OUT loaded with
330
Ω) (antenna level = FMIFAMP1IN – 31dB)
IF Amplifier 2 (Input at FMIFAMP2IN, fc = 10.7MHz, no mod) (Output at FMIFAMP2OUT loaded with
330
Ω) (antenna level = FMIFAMP2IN – 45dB)
Gain MUST BE SET to 14dB for ISS operation.
