Can the NAB be DOGE'd of our tax $$$$$?

My dumb question of the week. Does the National Association of Broadcasters, (NAB), take in any funding from the federal government? And, if so, can that be DOGE'd out? If, they are a 501C6 non-profit organization, let them fund themselves. Hey, NPR and PBS are getting slashed of tax $$$$, so it would seem that the NAB should be looked at next. I understand that they have their offices right next to the FCC in Washington. [en.wikipedia.org] Thought that this might give a clue, but not from what I see here.
