Default Re: Improving Selectivity In Vintage Receivers

The discussion is interesting, but is very speculative.

Referring back to the ideas of our Dutch friend (radiofun232), it seems to me that his idea of maybe 1 or 2 BJT followed by a FET with a sprinkling of ceramic filters is a "minimal-effort" thing to try. If it didn't prove to be a great outcome, it could well be very informative. Anyone want to critique that approach, ideally in a way the at the 'hams' can understand ?
