We present the results of an all-sky radio survey between 5 and 9 GHz of thefields surrounding all unassociated gamma-ray objects listed in the Fermi LargeArea Telescope Second Source Catalog (2FGL). The goal of these observations isto find all new gamma-ray AGN associations with radio sources >10 mJy at 8 GHz.We observed with the Very Large Array and the Australia Telescope Compact Arraythe areas around unassociated sources, providing localizations of weak radiopoint sources found in 2FGL fields at arcmin scales. Then we followed-up asubset of those with the Very Long Baseline and the Long Baseline Arrays toconfirm detections of radio emission on parsec-scales. We quantifiedassociation probabilities based on known statistics of source counts andassuming a uniform distribution of background sources. In total we found 865radio sources at arcsec scales as candidates for association and detected 95 of170 selected for follow-up observations at milliarcsecond resolution. Based onthis we obtained firm associations for 76 previously unknown gamma-ray AGN.Comparison of these new AGN associations with the predictions from using theWISE color-color diagram shows that half of the associations are missed. Wefound that 129 out of 588 observed gamma-ray sources at arcmin scales not asingle radio continuum source was detected above our sensitivity limit withinthe 3-sigma gamma-ray localization. These "empty" fields were found to beparticularly concentrated at low Galactic latitudes. The nature of theseGalactic gamma-ray emitters is not yet determined.
