Although audio is my main interest, radio comes in as a close second. Radio predates electronic audio and much of audio’s technology has come out of radio. I’ve stumbled across the site Arcane Radio Trivia and have found it so interesting that I have read every one of its posts, starting from April 2005. It is written by Jose Fritz (I suspect a pseudonym) who apparently has a career in the radio business. Jose also contributes record reviews to the Stranded in Stereo site.
Arcane Radio Trivia covers all aspect of radio imaginable: from technology, history, radio personalities, books about radio, to what stations Jose has heard on his frequent road trips. His views echo mine: skepticism of the growth of corporate radio, support of independent local stations, and heavy skepticism of the FCC and NAB (National Association of Broadcasters). The postings seem quickly written and often have spelling or grammatical mistakes, but the content is fresh, and he posts nearly every weekday! There are often week-long tutorials or history lessons and many good links to other sites. Sample some of his archives and I’d bet you will find yourself wanting to read “just one more posting”.

Muchas gracias for the kind words senor. Please excuse the spelling errors. I am after all, an engineer.
Me, too. Your site is really inspirational to me - I wish I had the motivation and material to post almost everyday, like you do. What I especially like is the breadth of material covered. By the way, I have a huge pile of old radio magazines (from the 1920s to the 1950s) and if you want to scan any, let me know, and I can send some to you. My email is atwood at one-electron dot com. (You can put the pieces together here - I just want to minimize the spammers.) Keep up the good site!
Just an update: There is an informative interview with Jose Fritz about “Arcane Radio Trivia” here. It nicely fills in the biographical gaps.
