Re: module 'gnuradio.digital.qam' has no attribute 'qam_mod'

Yes, both QAM mod and demod depreciated. In GRC, look under the Depreciated tab under the pull down menu on the right.

Hi,
thanks a lot! I guess the constellation modulator is the appropriate replacement? What about the demodulator?

Best regards,

Hi Fabian - QAM was depreciated prior to version 3.7 of gnuradio. And   depreciation usually implies it doesn't work properly.    -- Cinaed    On 6/5/20 12:00 PM, Fabian Schwartau wrote:  
 Hi everyone,   just added the gnuradio-releases ppa to my Ubuntu 18.04, made sure all   old gnuradio is gone and installed it again. Version is 3.8.1.0 (using   Python 3.6.9).   However, after fiddeling a bit I made a small flow graph using the QAM   modulator, but when I start it, I get:   AttributeError: module 'gnuradio.digital.qam' has no attribute 'qam_mod'   Doc says it should be there. Installation problem? libgnuradio-digital   is installed.     Flow graph and generated python files are attached.   Anyone any idea?     Best regards,   Fabian     PS: Why is there a copyright for 2016, I thought its 2020 and I guess   there have been changes this year already.   PPS: Why do I get 3.8.1.0 if there is only an rc-1 for that version? A   release candidate is not a release in my eyes, but what do I know. ;)
