[AMRadio] RE:455KHz crystal? KWM2a trade?

[Vince Werber]

Ceramic resonator... had to look it up...  I get mine from
broken VRC/TV remote controls...  you can find them on scraped
out CB's also...  there are two lead and three lead types...
sort of like a ceramic filter but very small.. about .25 x .32
inches...  hope this helps...

Oh yeah, Rat Shack used to have them but I haven't been in one
of those places in 10 or so years...
