Hi Carlos - The issue is with the USRP source block. If you open up its options in GRC, under the tab "FE Corrections", there are 2 entries (IQ Balance and DC Offset), both of which are probably double quotes ("") ... these should be Python booleans, so True or False depending on if you want to use the option or not. Hopefully changing them to True or False will take care of your issue. - MLD

I am running macOS 10.14.6 and grc 3.7.13.5.  After troubleshooting the missing variable error in gr-ieee802 after a macport update, I now have the following error:

Traceback (most recent call last):

    return _uhd_swig.usrp_source_sptr_set_auto_dc_offset(self, enb, chan)

TypeError: in method 'usrp_source_sptr_set_auto_dc_offset', argument 2 of type 'bool'

The loopback block runs fine. It seems UHD may have changed? Anyone having the problem? I tried to upgrade gr to 3.8 but macports is only fetching 3.7

v/r,

Carlos
