Like most Lime stuff very short on 'real working package, click here to download' but the concept looks excellent, depending on what sort of DTV it transmits. Pi Zero, Picam and a lime Mini. Certainly scope for a tiny package.

This looks like the project Evariste F5OEO started a while back; the drawings look familiar.
Can I afford a LimeSDRMini
See his twitter posts from early January.

Hi Steve
I will be looking to see if the Lime Mini could add any extra functionality to the Portsdown. I have one on order which I hope to receive in early March.

I had an email a couple of days ago to say my LimeMini had been dispatched so it should arrive in the next week.

Minor update to the Lime situation.
I have managed to get a clean transmitted signal from my LimeMini using modified DATV-Express software.
However to get the best MER (>=36 db on Minitioune) the Lime has to do a transmitter calibration every time
the parameters change (frequency / power level). This unfortunately causes the Lime to emit RF bursts over
+/- 10 MHz from the tuned frequency. I am currently thinking about acceptable mitigation strategies for
this and that is why I have not released the code despite having posted some pictures on Twitter.
