Leeds Advertisement - "The Home of RADIO"
December 1931 QST Article

December 1931 QST
December 1931 QST Cover - RF Cafe[Table of Contents]
These articles are scanned and OCRed from old editions of the ARRL's QST magazine. Here is a list of the QST articles I have already posted. As time permits, I will be glad to scan articles for you. All copyrights (if any) are hereby acknowledged.
Leeds, which dubbed itself "The Home of RADIO," has been in New York since at least 1923, but this advertisement appeared in the December 1931 edition of QST. Leeds is still in operation today in Brooklyn under the name of Leeds Radio. Looking at the ad is a step back ninety years into the past, but the nostalgic waxing does not have to end there. If you want a trip back to the beginning days of the World Wide Web, go to the current Leeds Radio website. It's format-less text presentation with basic hyperlinks is circa 1992 when bulletin boards ruled the day and the Mosaic browser was just giving web surfers their first taste of a GUI. The only images I found on the Leeds website were a few scans of old advertisements like the one shown below*.

* Update: 1/11/2013: A Leeds Radio employee contacted me and provided a web page with links to some their
                                vintage ads in QST. The pages below are not in that list, so you are still getting a little new
                                material here as well. Leeds Radio also has a page with a couple technical papers.

See all available vintage QST articles.
