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.
