I’m sorry to hear your health troubles are continuing. I know that must be very scary for you and Mrs. Viking. You’ll be in my prayers.
20th Century Radio just plays old time radio shows, no jocks, only liners. Their website seems to be messed up sometimes: http://20thcenturyradio.com/ But you can also stream it on TuneIn: http://tunein.com/radio/20th-Century-Radio-s129131/
At 6PM Central on Sundays, they play Dragnet, Gunsmoke and other classics we’re used to. Their website has a full schedule of their shows on it, too. It’s a good alternative to Murray, even though there’s no announcer.
In this case, no announcer is better than Murray. And that website needs fixed, bigly. It took several minutes to load, most of the graphics and Flash content was broken, and after a few more minutes of buffering, I gave up.
