Last week, we reported on the FCC’s release of a Public Notice announcing the recomputation of new power levels for Pre-Sunrise and Post-Sunset Authority for AM stations.  These computations were done because of the change in Daylight Savings Time that goes into effect this weekend.  We’ve heard from clients, and saw in yesterday’s broadcast trade press, reports that these computations are incorrect for a number of stations – often finding interference to foreign stations where such interference should not be a concern.  While we understand that the FCC is recomputing these authorizations – if you haven’t checked the authority that you received last week, do so now, and let your Washington representatives know if you think that there is a problem, so that it can be fixed before the time change this weekend.
