In case you haven't been following all the collections at archive.org, here's an article that showcases some amazing science fiction episodes from the early 1950's Dimension X radio show. Fifty half hour shows are available at the archive.org site which should be a good TV replacement for a week or two.
From the site:
Dimension X made its mark by adapting short stories by acknowledged masters of the craft: Isaac Asimov, Ray Bradbury, Robert Heinlein, and even a non-genre-bound literary mind like Kurt Vonnegut. All of these world-creators knew well the value of imagination, and radio, in its way, stood then and remains today the most evocative, imagination-driven medium of them all.

I would also call everyone's attention to the "X Minus One" radio series which was a more successful reboot of "Dimension X". The producers were the same, some of the same stories were dramatized (e.g., No Contact, Mars is Heaven), and some of the shows were direct rebroadcasts (e.g., There Will Come Soft Rains, Zero Hour). Those are also available at archive.org. Enjoy! I do regularly. [archive.org]
It's really quite a simple choice: Life, Death, or Los Angeles.
