Like with the libretech-cc, sdr104 at 200Mhz works "mostly", but, with some sdcards, it does not - please see below. The same sdcards appear to be working fine on my laptop. This is something I have not been able to crack yet on the libretech-cc. I'd suggest dropping sdr104 and keeping the max frequency at 100Mhz until we can figure out the problem here.
