I do have a Racal Instruments 6103E GSM Digital Radio Test Set which seems to work well so far. I have tested some SIM800 modules (mtk6261) with the internal BTS. Not sure if that will fall short or not but I'll take things one step at a time. When I need a CMU200 I'll probably get one. :) > Another question: is there any way to run any official MTK-based > firmware, however non-free and blob-laden it may be, on Fernvale hw? Probably. I know from reading that Bunnie and Xobs who designed fernvale did run standard firmware/OS on some similar 6260 based devices. Maybe we could track down a good firmware and test on fernvale. For what it's worth the fernvale isn't exactly my main target. I would much rather use a SIM800 module or eventually design of my own. > Has anyone actually done it and posted howto instructions?

I don't have any clue about these details.
