Re: IF amplifier question

Richard,

+1 on John's comments. I built a 40/20 superhet with 9 MHz receiver a couple of years ago. I used a feedback amplifier following the diode mixer and also following the crystal filters. Performance was excellent with these amplifiers. If you have a copy of EMRFD, Table 2.2 on page 2.25 gives resistor values for different gains. Section 2.7 discusses the design procedure.
