[Discuss-gnuradio] tunnel.py and low bit-rates

2007-06-01 Thread Brett L. Trotter
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 v

Ok, great. This simplifies things; I was afraid I was going to have to create a modulating circuit to modulate those low-frequency timing signals so they could be captured along with the 2 MHz am-modulated signals using a single tuning frequency. I have some questions about the deinterleaver.

I've tried to do the same thing as http://lists.gnu.org/archive/html/discuss-gnuradio/2007-05/msg00117.html However, it reports an error saying there's no top_block in the module. I've I manage to solve the init problem, I have problems with the runtime! Anyone knows why? Thanks!!
