1941 National QSL Disc


Here’s an idea from 75 years ago that apparently never caught on. It’s a QSL “card” in the form of a recording disc. Using a recorder such as the Wilcox-Gay Recordio, the operator would record the other station’s signal. Then, the traditional QSL data would be written in with a “special marking ink.” The blanks were from the National Recording Supply Co. of Hollywood, California. The manufacturer promised “unlimited playback with wide frequency response and a minimum of surface noise.” The blanks retailed for a dime each. This example was shown in the May 1941 issue of Radio News.

The disc is marked “Copyright Pend. National QSL Disc.” The magazine’s April 1941 issue┬áprovided more detail. It noted that “recent developments indicate that many amateurs now possess recording equipment and, instead of the old-time postcard, now use a disc to record other amateurs’ talks and send them through the mails.”
