The Xtal Set Society wins our "Good Guys of the Month" award. In an effort to improve the performance of my Vatican City Crystal Radio, and my hellish regen, I ordered a Hi-Z crystal earphone from the Society. It arrived very quickly, along with a free copy of their newsletter, their amazing catalog, and a free piece of candy!There is great stuff in the catalog, and the newsletter seems like gold mine of technical info.

ReplyDeleteIs the direct link to xtal radio society forums. For reasons known to the owners, the link is not publicized. This is where the xtl radio nuts hang out. Dave Schmarder's forum is another great place for xtl radios, regen's, etc.

Here's a link to an old article from Popular Electronics for a crystal set that will drive a loudspeaker!
