Sadly I don't get that broadcast channel where I live, BUT I did discover that Pluto.tv has two dedicated Star Trek channels. That app comes built into most smart tvs, is a lot like watching old school broadcast channels, and most importantly, it's free! (I swear I'm not being paid to advertise, just stumbled on it a while back and it made me happy. It's like a free Trek marathon running all the time.)
Star Trek (mostly TOS, apparently): https://pluto.tv/en/live-tv/5efbd39f8c4ce900075d7698
More Star Trek (TNG era thru Voyager): https://pluto.tv/en/live-tv/634dacf51d90320007fcd5fa
