The oldies format has returned to Austin's FM airwaves, courtesy 92.5 KXXS. Less than a month ago, the station switched, along with its simulcast partner, 104.9 KTXX, to sports/ESPN; now, the station has adopted Scott Shannon's True Oldies Channel (ending its simulcast with KTXX).
The True Oldies Channel is a satellite-based station which plays songs from the late 50s to the late 70s (see, for example, their recent playlist using this link) and claims to have a much larger library than most terrestrial oldies stations. Whether that is true remains to be seen, but according to at least one person who has already heard the format here in Austin, nary a human voice has been heard. (Aside: I don't necessarily think that constitutes much of a problem, given people's use of iPods and the link, and also given Bob FM's success despite (or because of) their being mostly jockless.
This change to KXXS represents the first real return of the oldies format to Austin, since "Oldies 103" became Bob FM in 2004. Sure, there have been rather half-baked attempts to bring oldies back to Austin before, such as KITY (whose website still erroneously claims to have a translator in Austin) or Majic 95.5's subchannel, KKMJ-HD2 (which, last I heard, was playing 60s-70s oldies, but I can't verify, as I do not have an HD radio), but KXXS is the first real attempt at an oldies format on FM in Austin. Oldies 103 consistently pulled top-ten ratings in this market, so this could be a pretty good move for KXXS, though the target audience of oldies may be getting too old for advertisers' tastes.
KXXS has filed with the FCC to move its city of license from Elgin to Sunset Valley; this can only help its penetration in the Austin market. The oldies format should also be a draw for listeners of stations which have recently switched to all-Christmas music (Majic, The River), and so I would not be surprised to see a major improvement in the ratings for KXXS in the near future.
Update 8/15/11: People looking for the oldies format should check out 98.9 in the future; see here for details.
