It appears they fused what they learned from gsoc and the 90 into one lower powered unit.
They pinched off an fw update for the 90 after concentrating on the new rig, new fw makes mine crackle on sigs weak and strong so back to the 77b fw.
As noted in the story, the 6100 seems to respond with images to ambc and hfbc, not good! Sadly like its father the 90 in this respect.
