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.

Recording:

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 https://yle.fi/a/3-11502533

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

Shortwave’s the WORD

Leave a reply

Good day shortwave folks from myself FastRadioBurst 23. Here’s some text from the Imaginary Stations crew letting you know of our audio communications this week. On Sunday 16th June 2024 at 0900/1300 hrs UTC on 6160 kHz and then at 2000 UTC on 6160 kHz and 3975 kHz we bring you more on the WORD theme with KRBR via Shortwave Gold.

We will be bringing you some additional punctuation, acronyms, commas (including one especially flown in from Oxford in the UK) and a bit of wit from Roget and his Synonyms (if there’s any space left on the page). We will also be hearing from a special guest from the WHPY era. Listen in for more words via the ionosphere.

Then via WRMI on Wednesday 19th June 2024 at 0200 UTC on 9395 kHz we bring you the original WORD show. We’ve words and letters, books, (Radio Phonics) laboratories, libraries, acronyms, verbs, adverbs and possibly an appearance from the Jazz influenced An ampersand or two. We must make it very clear that this show is in no way connected to STET, the very popular proofreader’s radio station. We apologise for any confusion that it may have caused last week.

Here’s more on WORD:

For more information on all our shows, please send your collection of words with spaces in between to [email protected] and check out our old shows at our Mixcloud page here.
