WVIP only ran brokered programming very briefly on a subchannel. About two years ago, they carried a Caribbean radio programmer for a few weeks (in addition to the Caribbean shows offered on the main channel).
Then they offered the syndicated Music of Your Life on HD2, Country Hits HD (programmed in house) on HD3, and a simulcast of their AM station WVOX on HD4. WVIP has been trying to rebroadcast a subchannel on a translator, but the attempt to get it approved by the FCC has been mired in challenges brought by a station that is on the same frequency.
WVIP is now broadcasting an HD1, with no subchannels. They did run a silent HD2, HD3 and HD4 for a few weeks in August.
WWPR's attempt to lease its HD2 to another Caribbean broadcaster did work out badly. The broadcast aired just for a few weeks, and then the broadcaster apparently stopped providing programming, didn't pay the leasing fee or both. WWPR HD2 ended up broadcasting an open carrier for almost a year, till it was shut down.
