Had one of their TNC-2 units Back In The Day.<br /><br />Didn't mention them because they're well beyond what the person looking for a "$5 SDR dongle" with a Google search would ever consider.drjimhttps://www.blogger.com/profile/05647484115197408897noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-44055571563673475132020-11-15T17:25:41.048-05:002020-11-15T17:25:41.048-05:00drjim beat me to the HackRF solution.

(See the 1st 4 letters of the name.)<br /><br />Then there is TAPR. They have a build-it-yourself set of SDR modules. They are not cheap and the stock tends to sell out whenever they get some boards in. I have not looked at them in a long time, so I'm not sure if they are still doing that or not.Zendo Debhttps://www.blogger.com/profile/00094772654735415974noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-33379716097411476752020-11-15T01:39:22.769-05:002020-11-15T01:39:22.769-05:00How about 5, 10, or 20 Watts narrowband around one...How about 5, 10, or 20 Watts narrowband around one of 100, 200, or 400 MHz; but a newer transmitter design which can generate the newer modulation schemes generated by open source? Sell it as a kit, a circuitboard with the tiny surface mount devices already attached plus a bag of larger through-hole parts.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-80992299774184031852020-11-15T00:53:16.536-05:002020-11-15T00:53:16.536-05:00I had one of the HackRF SDR units for a while.

While it was <i>capable</i> of transmitting, it required a pretty good understanding of GNURadio to make it do so.<br /><br />It's also NOT in the "$20 class" that most people I've met expect these "SDR Dongles" to sell in. The "$20 class" dongles are pretty junky for other than intended use from my experience. I've got one of the Gen-You-Ine "RTL-SDR" dongles, and it's quite a bit better than the cheap ones.drjimhttps://www.blogger.com/profile/05647484115197408897noreply@blogger.com
