The FCC has extended until Sept. 7 its reply comment deadline in the computer modeling docket.

The proposal would allow stations to use computer modeling to demonstrate that AM directional antennas perform as authorized.

The proposed rules also would permit use of method of moments computer modeling to assess the effects of tower construction in proximity to AM antennas.

An ad hoc group of AM heavyweights including radio broadcasters, equipment manufacturers and consulting engineers — the “AM Directional Antenna Performance Verification Coalition” — asked for more time to respond to comprehensive comments filed to MM Docket 93-177. The FCC agreed and the replies, which had been due earlier, are now due Sept. 7.

There’s a lot of engineering horsepower on the side of this issue, though as NAB’s tech folks recently pointed out in their newsletter, some commenters are concerned that the proposal relies too heavily on method of moments computer modeling and not enough on actual field measurements. Still, look for approval on this issue soon.
