\"Credit-Card-Crystal-Radio-4\"<\/a><\/p>\n

Many thanks to SWLing Post<\/em> reader, Vance, who writes:<\/p>\n

You got me hooked on those little credit card sized radio kits from an eBay seller<\/a> so much that I have bought a few more of his kits. I’ve found them to be so much fun, that I have started looking elsewhere for other tiny radios.<\/p>\n

I came across this the other day and while it is not a kit, I was wondering if you or your readers had ever tried them and if so, what your opinions are: http:\/\/jdradio.weebly.com\/index.html<\/a><\/p>\n

\"earpiece-radio\"<\/a><\/p>\n

I know it is likely more novelty than performance, but the prices seem ridiculously low for individual buyers.<\/p>\n

Also seen here: http:\/\/www.centretradegroup.com\/Radio.php<\/a><\/p><\/blockquote>\n

I’m not familiar with the earpiece radios in your links. I have read through those sites, though–unfortunately, as I’m sure Vance\u00a0noted, they lack any in-depth information.<\/p>\n

I did a quick Google search and can see that these radios (both the FM and AM versions) have been around for many years–some references\u00a0go back to 1999.<\/p>\n

I imagine the earpiece radio uses the same auto-tuner that became quite popular in the late 90s. Simply press a button and the receiver auto-tunes to the next strong station: no memories and not manual tuning. Indeed, I used to attend trade shows in Europe in the late 90s and several vendors actually gave away branded novelty radios (in a variety of shapes) with a similar tuner.<\/p>\n

Readers: Ever use\u00a0one of these earpiece radios? Please comment!<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
