WJZ (Channel 13) had been supplying its feed to WMAR to use on WMAR's website "as a public service for all the Baltimore viewers, to keep them aware of the situation," WJZ spokesman K.C. Robertson said. Shortly after 5 p.m., he said WMAR and WJZ technicians were working together to get WMAR's signal back on the air. WMAR's transmitter is in the WJZ building. WBAL officials said they had also offered to help if necessary.
