Hi,
I'm pretty new in working with gnuradio. Could you please tell me a bit of
detail about how to change the symbol rate, transmit power, and receiver
acquisition loop (command line? the script code?) Thanks a ton!!

We use OptionParser for all of our command-line applications which has
the neat attribute that you can use "-h" with the command. This will
print out the help page for any command-line program.

Hi All,
We are trying to set different modulation and demodulation schemes in
gnuradio example tunnel.py. The default is gmsk, which works fine. But
when
we used -m dbpsk option, the two PCs can't ping each other (although
after
ifconfig setup, both sender and receiver have output like: Tx:
len(payload)
= 192 ). I looked through the script
tb = my_top_block(mods[options.modulation],
demods[options.modulation],
mac.phy_rx_callback,
options)
It should be ok if we specify a different modulation with -m, unless
there's
other settings needed. Can anybody help us with the problem? Thanks a
lot.

I have used DBPSK and DQPSK fine with tunnel.py. You will probably have
to play with the symbol rate, transmit power, and possibly the receiver
acquisition loop settings.
