Many thanks to SWLing Post contributor, Adi, who writes:
Hi Thomas, this video just popped for me on YouTube. I searched the SWLing Post and didn’t find it, it’s not new so maybe you missed it.
Thank you, Adi. I’m almost positive I’ve posted this one before–but if I have it’s been so long it should be re-posted! A wonderful nostalgia trip! Thanks for sharing.
Wonderful! Heard many of those, on air, in the past…
If you have an Android there is an “Interval SIgnal Ringtones” app available from Play Store.
I ran across that YouTube video sometime last year. Brings back some great memories.
Thanks for posting this. Many years ago there was a set of LP records of interval signals and announcements which someone transcribed to MP3 files and made available on line. I down loaded them but lost them in a crash. Does anyone have a copy?
Are you talking about the series of interval signals that was produced by Ian McFarland?
How about this

I never had it, but Hallicrafters issued a record, maybe just a 45, of spunds from shortwave. More like a promotional item. They may have included it as a bonus when buying a receiver.
