[Discuss-gnuradio] qam modulation blocks in GRC cannot work btw two computers?

Hi all, I'm playing with qam modulation and demodulation blocks using GRC. To begin with, I built a flow graph in one computer as follows: File source>packet encoder>qam mod->qam demod> packet decoder->file sink It worked well. The file sink can get what is in the file so

[Discuss-gnuradio] "QAM Demod" error in GRC

Hi all, I'm using GRC and the simple flow graph(1) at receiver is as follows: Usrp source>qam demod>file sink It works fine at first. However, when I tried to execute another similar flow graph(2) that was built before UPDATING GNURADIO from 3.5.0 to 3.6.0. an error occurs: Gener

[Discuss-gnuradio] QAM Mod and QAM Demod block in GRC

Hi all, I'm working on an experiment which needs to modify qam modulation block in gnuradio. But I cannot find the source C++ file the qam blocks use. e.g., OFDM demod block uses digital_ofdm_frame_sink in gnuradiobuild/gnuradio/gr-digital/lib. What about qam blocks? Thank you for your help!
