Topband: Xtal Filter +1

[Petr Ourednik]

Hi all,

I believe You are looking for something like tunable xtal front-end
preselector 
which I build for several of my ham friends years ago and posted there:

http://www.radio.qrp.cz/1/clanky06/preseletor.htm

Originaly it was published by Peter, G3IPV in the ham radio magazines
years ago.

The main issue in practice is the small tunning range otherwise it works
like champ.
