The Squeaky Wheel (a nickname given by radio listeners) is a utility shortwave radio station that broadcasts a distinctive sound. From around 2000 until 2008 the station's attention tone was a high-pitched two tone signal that vaguely resembled a squeaky wheel. From 2008 the channel marker changed to two different tones in a short sequence repeated with a short silent gap. The frequencies were 5473 kHz (day) and 3828 kHz (night).[1][2] Several times voice messages in Russian military format have been reported. The exact transmitter site is unknown, but is thought to be near Rostov-on-Don, Russia.[2] The signal strength is weak in Central Europe and the signal sometimes even disappears for days in the noise.
