I have three Hack RF One boxes here on the bench, generating three DAB multiplexes. All these things are is software-defined radio transceivers. They can be configured to work anywhere from about 150kHz to 1 GHz. I've used them as test sources for receiver alignment, as the local oscillator during receiver development, for generating AM, SSB and FM signals and many more uses too numerous to remember.

The clueless Daily Mail are trying to make a story out of nothing - as usual.

Albert id love to see any pics or vids of this.

Are you using ODR software, and if so what are you running it on, debain raspberry etc??

In the next couple of months im going to try a little test setup.
Id love to see some pics as you have it set up and running, topman

I would like to buy one but seem very pricey and for the price you could get an FM rig for it.

You're missing the point! The Hack RF One is a very general solution to generating (and receiving) signals over a wide range of frequencies.

I'll snap a couple of pics of the lash-up later on. I'm building some DAB+ modulators into 19" rack boxes. The boxes actually contain industrial computers, and I've added soundcards and the Raspberry Pi encoders and the RF parts into the huge air-conditioned voids above the motherboards. These will be shipped to southern Europe next week.

Interested in grabbing one myself.. Be good to scan network traffic at radio tower's etc.

Are you using the Great Scott hackrf or the half price Chinese jobs?

The ones that I've boxed up in the 19" rack boxes are original "Great Scott" ones. I've just got some clones of them from Shenzhen for $45 each. If they work OK, we have cheap DAB!!!

There is also the $250 EasyDAB v2, which moves much of the processing overhead to an FPGA and gives a few milliwatts at the output frequency. This is a really elegant solution (if slightly pricier), but it eliminates a lot of the hassles and reduces the amount of computing required.

We've tried one of these out in a test site with a somewhat iffy home-made broadband FET PA tacked on to the end. Once we got the filtering sorted out to eliminate the crud (and I turned down the output power of the EasyDAB board), we had a superb DAB+ multiplex with better than expected coverage. The whole rig - including the soundcards, Raspberry Pis, boxes, connectors, power supplies, aerials and cables came to under €2000.
