This is a bit of an ad, but I swear I don’t sponsor H&I. I just use them a lot. My wife and I bought “bunny ears”/an antenna for our TV when we lived in the Midwest. We also watch H&I on the west coast. Almost every night they play one episode from each popular, live-action, series in order of production: TOS, TNG, DS9, Voyager, Enterprise. The start time depends on your location, but I believe it starts around 7pm Central Time.
It has commercials, but I don’t mind since the shows are “free” over the airwaves. I haven’t tested in the east coast but I bet a lot of the country has some coverage.
Our antenna also has some MacGuyver, Stargate, Baywatch, and some other popular old shows. I just think it’s cool that we can have access to such great shows with a one-time cost (and commercials). It’s also great because it works during internet issues (as a backup if streaming is failing). My wife and I often just left it on in the background while we worked or made dinner!
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
They also occaisionally get temporary channels with some of the newer shows. I recall Picard was on there not too long ago. SNW season 1 was also on Youtube, not sure if it’s still up or if it was only in the run-up to season 2. Paramount+ also gives out free monthly trial codes like candy – but you have to input a CC and remember to cancel.
SNW s1 was free on YouTube too in the runup to s2 (might still be).
