The next meeting would be a great opportunity for someone to bring his
copy of the ARRL Handbook, and open it to Chapter 12, which is about
receivers. It talks about the superheterodyne principle, the advantages
of using it, flitering in the IF, multiple IFs, the bandwidth of various
signals, and so on.
One of the best things we can do with a new ham, or with any ham who
wants to learn, is point them to the Handbook.
