Has anyone poked around with the DSP on the modem? IIRC at least one LTE channel is inside the (33cm?) HAM band and the DSP code is floating around on github. I've skimmed over it, it's definitely some kind of SDR baseband firmware (unlike the "broadcom wifi firmware" which just sat between the MAC/PHY/PC and pushed buffers around.)
