Hi Craig,
good to hear that you're working on something as exciting as MTK support
of OsmocomBB.

I hope to make a usable phone. Currently my plan is to
dig into the MT6260 as
started by the fernly/fernvale project. Current target is the SIM800H which
contains the MT6260. I saw both that sysmocom has a $150 fernvale setup and
Lime SDR has a USB bare-board for $250+ but I have to stick with something that
is "phone" like and so am working on designing a small SIM800H/MT6260-based
phone which can be expanded and/or used to experiment.
I would strongly encourage you not to spend time in designing more
hardware rather than working on the software side of things.
Understanding the DSP/ARM interface of mediatek baesband chips is the
primary key into creating a L1 adaptation of OsmocomBB that works on
such hardware.
If there was something like LimeSDR that was small and
less expensive I would
go that route. I imagine there will be before long. :)
I don't think a General Purpose SDR solution will lead to a usable
phone. The GP SDR is too large and power hungry to begin with, and
then you need a host processor that can do all the signal processing,
and you're suddenly talking more about an embedded PC rather than a
battery powered phone.
Meanwhile, I'd definitely like to contribute as I
can to MS software/
osmocom-bb. I will do what I can.
Pleaes do so. I'm happy to review and give feedback.
