How does this affect clients?
It depends where you are working how you might be affected. Current knowledge of transmitter sites is invaluable and both RSM and WUNZ have plans to develop tools to establish what DTT is operating from where. The information is already available in the RSM SMART database but it requires a good sense of geography and patience to interpret it.
