makezine.com — "This is an amateur HF 100 watt transceiver that is completely software driven. The software and updates are all free. There are NO controls on the box itself except a power switch. Users are encouraged to write their own software to control the radio as it is open source and in fact many do."

What does that even /mean/?

Supposed to be a reply to MateFrio's comment.thank god not everyone is a moron.This is a radio directed to HAM radio ops. It's not designed so you can listen to IMUS in the morning.

@Urusai:US$1375 is actually a pretty reasonable price for an amateur radio with these capabilities. This ain't no broadcast radio job - it's capable of being used to talk directly with people over incredibly long distances. Zik (VK3MHZ)

obviously I was completely wrong, but before I read past the title, I thought the article was about this <a class="user" href="http://www.erikyyy.de/tempest/">http://www.erikyyy.de/tempest/</a> projectThis is very cool though

The Flex Radio has been out for a little while... but ok...If you're interested in Software Defined Radios, check out the SoftRock receiver: <a class="user" href="http://www.amqrp.org/kits/softrock40/">http://www.amqrp.org/kits/softrock40/</a>(there are newer versions available)...or the FireFly transceiver for those of you that are licensed:<a class="user" href="http://qrpkits.com/firefly.html">http://qrpkits.com/firefly.html</a>73,N5DUX

So is this one of those devices they say can transmit and recieve:RadioBluetoothWifiand well, basically any other radio frequency channel? I think it was submitted on Hack-a-Day or Engadget a while ago.

@blownfuseThe numbers you quoted (12KHz through 60MHz) describe the receiver's Intermediate Frequency (IF) sampling capability, *not* the actual frequency bands it can work in. Few signals (besides UWB) deviate more than 60MHz from their carrier frequency; to receive a signal at e.g. 2.4 GHz you use an expansion board which removes the carrier, converting the 2.4 GHz +/- 20 MHz range (for example) to 30 MHz +/- 20 MHz, which is then run through the high-frequency A/D converter on the main board.The signals you can receive are limited mainly by your choices of antennas and expansion boards; software-defined radios like this have been employed to send/receive AM, FM, NTSC TV, DVB (digital TV), etc. with a great deal of success. The main limiting factor for UWB applications is the speed of the link between the SDR and the PC -- 60 MHz is close to the current limit for quadrature-encoded signals over USB2.0.
