The Squeaky Wheel at night: the same squeak on 3363.5 kHz
Once 5367 kHz stops carrying after dark, the Squeaky Wheel's grinding marker continues on 3363.5 kHz, where night-time shortwave travels far across Europe. The night entry of the Rostov marker.
What you hear
The same short squeak, repeated endlessly, that the day frequency carries, and the same rare chance of a voice message. The station itself, its history since the mid-2000s and what is known about its purpose are covered in the main article.
Who transmits and why
The same transmitter near Rostov, and the same military net. The night frequency exists because physics demands it: a 5 MHz signal that covered half of Europe in daylight shrinks to a few hundred kilometres after sunset, while 3363.5 kHz does the opposite and opens up with the dark.
When and where to listen
The marker shows up on 3363.5 kHz around dusk at the transmitter and stays until dawn there, so for European listeners this is the evening and night entry. Receivers in eastern Europe, the Caucasus and Turkey hear it strongest; from central Europe it is steady on a quiet night, from the west and north fainter but often there. The frequency lies inside a tropical broadcasting range, so weak broadcasters from far away may appear nearby; the squeak is easy to tell from them on the waterfall. USB works as it does by day; AM is an option when the signal is strong.
