Wow, Rob. I’ve never seen this receiver before. Perhaps one of our commercial receiver experts (*cough* Dan Robinson *cough*) might be able to shed some light on this model!

Can you help Dan identify this mystery interval signal?

Hi Thomas

I was going over a few of my old cassettes today and discovered what seems to be an interval signal, but I cannot seem to place it.


Unfortunately, all I can tell you is that it was made sometime in 1971.

I’ve done a little checking with Interval Signals Online but no luck so far. The recording is right at the end of a cassette and you can hear the tape run out abruptly, so no ID, language or frequency info is available.

[…]Any ideas about the mystery IS?


Readers: If you can help Dan positively identify this interval signal, please comment!

“What connects the Finnish YLE station and Prague?”

Professionals at the station often had a background as radio amateurs or radio electricians. Photo from YLE’s archive.

Hi Thomas, a post on Reddit with a picture of radio stuff lead me to Google for its source.

It led me to this page

My Finnish is not as good as Google’s, but even with its poor “auto” translation, the story can be fairly understood and bring to life the 1968 Soviet’s invasion to Prague from the YLE side.

That article was written in a book by an YLE broadcasting engineer for 40 years. A few pages of his book can be viewed here with more nice pictures.

As a child I do recall that event in the local news coverage and it was also immortalized few months later, in the Israeli music scene with an amazing song, very popular till today.

I’m sure many of SWL’ers can share some of their memories of that Soviet’s invasion to Prague in 1968.

Best regards, adi
