The gradual approach of autumn always makes me nostalgic. This time I spent an afternoon searching for shortwave interval signals that I remembered from the past. Most of the stations have since changed their program format or station name, moved from the airwaves to the internet, or closed down altogether. The remaining ones have changed their interval signals, but I wanted them as I originally heard them, and managed to find twenty.
My source was
Interval Signals Online. Great site! The only problem I encountered was that the online files were all M3Us, which are playlists that my browser can't open directly. It downloads them to my hard drive instead, and I have to open them in my media player. This works, but I wanted to keep the MP3s for offline listening, so I opened the playlists in a text editor and copied the URLs, which pointed to online MP3s. Then I pasted the URLs into the browser's address bar, and once the browser started playing them, I hit pause and was able to download them. Of course, I keep those files for personal use and would never distribute them elsewhere.
