WFMZ a station in Allentown,PA carries both DS9 and Voyager. Its on 129W.L. and Dish might keep this indy FTA but the right receiver is needed. TNN has exclusive rights for The Next Generation as of now.
WFMZ, WPHL and many local stations lost 7th Heaven reruns. ABC Family acquired the rights for this show, and the reruns currently no longer seen 5 days a week on any local stations.
PS: You can thank these cable networks owned by media giants for acquiring rights for these shows, then decreasing broadcast viewership to lower and lower levels while cable market share grows, and then these cable channels have "increased programming costs" and need more money every year. And then there is Congress's mandate to broadcasters turn over analog channels leaving many having no access to clear digital signals, so free TV dies. Cable/satellite providers have to pass down programming costs to its subscribers and want a nice margin to keep to themselves.
