[Discuss-gnuradio] howto_square_ff require Gruel

Tom Gong, It seems I have the same problem as you two have been discussing. I create a module (howto) using the gr_modtool and added hwto_square_ff using 'gr_modtool add'. I completed the tutorial, but cannot make anything. I went back and created a build directory and then ran cmake ../ as

Perhaps this is a bug, but I can't reproduce that error, not with 3.6.1, master, next nor with any branch of gr_modtool. Please tell us - where libgruel.so is (if it's somewhere exotic, Josh's answer is all you need) - which version of GNU Radio you're using. Also, try and build

[Discuss-gnuradio] OOK Mod and Demod

Hello, I am trying to create an ook modulation and demodulation block. So far, I have created a block similar to the bpsk block. I changed my constellations points to 1+0j and 0+0j. I want a rectangular pulse to be transmitted for a 1 and nothing for 0. I was told I could do this by changing the

Re: [Discuss-gnuradio] Separate samples from 2 receive channels (Josh Blum)

Hi, Josh, Thanks a lot! Yes, after reading the rx_multi_samples.cpp, I understand that each channel has a buffer and they are placed in a vector buff_ptrs. For people who may want to use this example in the future, you need to add codes for setting frequency, gain, and antenna. Current example
