That´s a nice crystal radio receiver, more info can be found here:

By the way How can you buy in Japan Yahoo ? Those sellers don´t like to send items abroad.


Looks like a neutrodyne (predecessor to superhetrodyne) radio, though I don't see anywhere for the tubes. An antenna wouldn't have the neutrostage adjustment.


This is very interesting:

Huesby - there are several people out there who live in Japan who offer yahoo auction bidding as a service to people in the US.

I've used this one a few times - http://www.japonicamarket.com/

They will bid on your behalf, the item gets shipped to them, then they ship it to you. You decide your max bid and paypal them that amount of money. If you don't win, they quickly refund your money. I've never won anything (always been outbid) but my refund was promptly issued both times - the only thing that held it up was paypal put a 4-5 day temporary hold on the refund. You would of course want to convert USD to YEN first on a site like this http://coinmill.com/JPY_USD.html

There's a lot of interesting radios in Japan that you just don't ever see pop up on ebay.

Oh, and the item itself here was a Freed Eisemann.


I agree with Huesby. That is a double-tuned crystal radio. One tuning knob is for the antenna tank. The other tuning knob is for the detector tank. The coil is tapped, allowing the user to change the effective inductance of the coil. The rotary switch in the middle selects which tap of the coil is used.

Pretty neat looking older set.


Check out eBay auction no. 140767846119

It's a "homebrew" crystal set made from old radio parts. The builder is a member of the Antique Radio Club of Schenectady (NY) arcsweb.webng.com
