Very clever way of using SSTV signaling to not only send a picture greetings but also a short melody!

While SSTV DX’ng I heard a very familiar melody while listening the transmissions. First I thought I heard wrong, but when this happened again I was sure this was intentional – and I was able to record it too!

Here is a video of the transmission, take a listen to the first seconds of it, sounds familiar? 🙂

Very very cool! Thank you for this experience I5UIN / MAX.
