This month’s DX Tool Box web site is:
www.intervalsignals.net/
Interval Signals Online
This site has a large archive or collection of many interval signals from around the world. An interval signal collection is (according to the site) “a collection of audio clips of foreign radio stations, with identification announcements in various languages, signature tunes and jingles”.
Audio clips will play the interval signal of each station you select. If you have old unidentified station, or hear a new station and catch the ID, a clip from the site might help you identify the station. Language is often a problem with foreign DX stations, but if you listen to what you heard and find an identical interval signal on the site you will have an ID for your station. There are both domestic and shortwave interval signals on the list by country. Once you click on the country then you can look by station type or station name.
It is simple to use and offers thousands of clips. I must admit that some of the clips are old archival clips but if you have an old unid they may be useful to help identify a station or two.
