microSD - probably 4 GB. It is user replaceable (not recommended), but not easily accessed (internal) -- watch for tested Manufacturer / Model. Not all microSD are recommended for a boot device. I have a 8 GB in my lab bench unit, loaded with a development chain (compiler, linker, libraries), OS, and many applications and haven't hit 2 GB yet.
It is not a software defined radio. Modulation is performed inside the RF-IC. We really like what SDR does, but for VHF/UHF+ digital modulation there are well known techniques and the RF-IC supports most of them. Using built-in modulators keeps part count and cost down.
