Look into the directory /usr/local/lib/python2.x/site-packages/gnuradio/blks2impl/ . It has many modulation schemes already implemented in Gnuradio. GMSK is infact the default scheme but one can choose various other provided in this directory.

Hello all, I'm new to GNU Radio and was wondering what kind of modulation
schemes were available. I know that GMSK is the default scheme for the
"..digital/benchmark_tx.py" file. I saw that the schemes are derived from
the "modulation_utils" file. I'm not sure the available options though.
Also, when the benchmark_tx.py script transmits from a file, how does the
data in the file get transmitted. For example if file.dat is transmitted
with contents "5123645AY...", are these converted to binary 1's and 0's
using ASCII or Hex conversion and then modulated and transmitted?
Any help will be greatly appreciated. Thanks all.
