WNUV received FCC authorization in 2013 to begin conducting tests of the OFDM-based DVB-T2 terrestrial television standard and other future television broadcast standards, with the aim of identifying the feasibility of next-generation standards for mobile device usage and 4K ultra-HD; the experimental broadcasts began on the morning of March 27, 2013. The tests ran between 1 a.m. and 5 a.m. and did not interrupt cable reception; the lost programs were aired on a subchannel of WBFF.
