So… the buck converter module arrived and I soldered it in and set the voltage to 3.8V. One of the voltages was wrong. It transpired that I had a resistor of the wrong value, not far out mind, just a few ohms… ok, 560K instead of 56K! Ahem. Right, fixed that and the voltages are all correct so the serit module got soldered in and the USB module fitted. It was now that I realised that one needs to first register on the VivaDATV forum for access before you can download the software. Yup, read everything first… Anyway, the pause allowed me time to go back to the workshop and add the resistor needed for the V0.8 and newer versions of the software. Did I mention reading everything first?

I got the software today and ran the test program. This came up with two errors to do with the USRC and LAV filters and fixed by running packages that come as part of the MiniTioune ZIP. And success, all tests passed.

I have a box on order but otherwise it’s a matter of testing on-air now, or testing using the feed from a satellite dish. But now it’s raining and the project QO100 dish is still in the workshop.
