Crystal radio credit card receiver
On a tip from my good friend Dave Cripe (NM0S), I just purchased this cute crystal receiver kit from a UK-based seller on eBay.
The price is 8 GPB plus 3.50 GPB for shipping. After PayPal currency conversion, I paid $17.63 US shipped from the UK-a very fair price. The kit is supplied with 5 meters of antenna wire, a high impedence earphone fitted with crocodile clips, and two double crocodile clip leads. Each unit is also tested prior to shipping. The seller also has a 100% positive rating on eBay.
I'll certainly make a post about the radio once I receive and build it. While there aren't as many blowtorch broadcast stations to hear these days via a crystal set, with an ample length of antenna wire, you may be surprised what you will hear. Certainly a fun and lightweight item to take camping or place in your bug out bag. No batteries required!
Update: Since making this post, it appears the item number has changed since the seller had to list a new lot of kits. Below, I've made two links that search eBay based on the description, not item number:
- Search via eBay US (best if you're in the USA, but scroll to bottom of screen to see this item under "International Sellers")
- Search via eBay UK (best if in UK or EU)
