In 3.03 and before, as opposed to CVS, one could add higher samples per symbol values to pick_bitrate.py and operate at lower bitrates than 35k. Currently, gmsk seems to be the only one that works via that method, dqpsk and dbpsk complain about sbs_to_mm not having an array key for the particular value of samples/symbol. Did it previously figure out something that worked and now uses a lookup? Similarly, even with gmsk which lets me go below 35k, I seem to have little to no success even with enough signal to operate at 35k. What can I do, or what can be done to operate in the neighborhood of 1KB/s throughput and require the lowest possible SNR? I've added in some error correcting code, but have almost no success below 35k even if the tunnel appears to set-up.
