Here's a couple updates on the HDTV scene here in San Antonio. Our PBS station, KLRN-DT, is multicasting two channels during the day and during the evening. Our local Sinclair-owned Fox and WB affiliates are transmitting 480i upconverts with worse audio and video quality than the traditional analog channels.
Also, KLRN, KABB and KRRT are all operating at significantly reduced power. Once the San Antonio stations go full power one should be able to view the reliably from San Marcos, perhaps even from further north.
P.S. Hope your local Fox station gets their act together soon. I'd like for at least one of the Fox stations in Central Texas to not suck.
Free over the air HDTV + Tivo HD + Netflix for Blu-ray and streaming = Bliss
