Last night I finished mounting all the small parts on the UI board and today the board got cleaned of extra flux (there was a lot).

Ready to build
All parts have now arrived and I am soooo ready to build my mcHF 
Turn your Raspberry Pi into a live HDTV transmitter
Please note that the information in this article is out of date and needs updating. I will do my best to update it soon.
In a previous post I wrote about using the UT-100C DVB-T modulator on linux and I promised to follow up how to use the modulator with live video sources. In this post I am going to describe how to setup the modulator on a Raspiberry Pi equipped with a RaspiCam camera module, effectively turning the Pi into a live HDTV transmitter.
Building the UT-100 driver on the Raspberry Pi
Building the UT-100 driver module on the Raspberry Pi can be done the same way as on the desktop. The only difference is that instead of “sudo apt-get install”-ing the kernel headers and sources we have to fetch them from the Raspberry Pi git repository and install them manually. Although my instructions are written with the UT-100C DVB-T modulator in mind, the procedure is applicable to other out of tree kernel modules as well.
Software Defined Radio the way it should be
I have been looking into various options for building my own radios again, this time taking advantage of software defined radio technologies. I’m not crazy about using a PC for running the SDR application. While a PC offers great performance and flexibility, it makes a clumsy radio setup not at all suitable for portable and mobile use.
