I have an old Ipod with old radio shows and a portable speaker for camping.

Listened to a lot of Gunsmoke, CBS radio mystery theater, X-1, etc

I suppose you already know about Internet Archive old time radio mp3s? Got prit-near everything for free. In case you hadn’t run into it yet:

I hit OTR shows from time to time.

Fort Laramie is one I like. Has Raymond Burr as Lee Quince captain of Calvary.
