Many thanks to SWling Post<\/em> contributor David Goren, who recently uploaded the Shortwave Shindig interval signal slideshow to his YouTube channel. David notes:<\/strong><\/p>\n

For the past 22 years or so, I’ve helmed the Shortwave Shindig, a long form listening session celebrating the art, history and culture of Shortwave Radio. This takes place in suburban Philadelphia at the annual Shortwave Listener’s Fest (which just marked it’s 39th year), sponsored by the North American Shortwave Association (NASWA). Our opening gambit for the evening is to play an Interval Signal medley. Interval Signals are short samples of music often incorporating a country’s national anthem, folkloric music, even bird calls…as an aid for tuning in the station prior to the official sign-on. Our resident musical genius Chris Johnson takes the Shindig’s anthem, the country gospel tune “Turn Your Radio On” and morphs it into classic Interval Signals from the golden era of Shortwave Radio broadcasting (including The Voice of America, Radio Tehran, Radio Kiev, Radio Norway, Radio Canada, Radio Australia and many more.) This year I added a slide show with a smattering of Shortwave Radio related graphics. I present it here for your listening and viewing pleasure. Kudos also to Jeff Murray for designing the ultra-snazzy Shortwave Shindig logo.<\/p>\n
