Radio Astra is an experimental AM shortwave radio station believed to operate from Germany. Since beginning operations in July 2026, the station has transmitted music, test programs, and various experimental broadcasts on several frequencies across the 75, 60, 49, and 43 metre shortwave bands.
The station stopped his activities in 43m and reduced activities in the 49m the 13/07/2026 and the same day due to propagation issue the station added a brand new transmitter in Wooferton, United Kingdom with an available power of 250 kW, the Wooferton transmitter can be recognised by his splatters of high power.
Frequencies[edit | edit source]
| Frequency | Band | Status | Notes |
|---|---|---|---|
| 3990 kHz | 75 m | Occasional | Not always active... |
| 4600 kHz | 60 m | Inactive | Not used anymore |
| 4880 kHz | 60 m | Inactive | Inactive because of interferences with Lodz Jedynka. |
| 4885 kHz | 60 m | Inactive | Inactive because of interferences with Lodz Jedynka. |
| 4935 kHz | 60 m | Main Frequency | Current main frequency. |
| 6070 kHz | 49 m | Primary | Secondary main frequency. |
| 6270 kHz | 49 m | Primary | Secondary main frequency. |
| 6275 kHz | 49 m | Inactive | Not used anymore |
| 6980 kHz | 43 m | Inactive | Not used anymore |
The station's primary operating frequencies are 4935 kHz, 6070 kHz, and 6270 kHz. Other frequencies are used occasionally depending on propagation conditions and operating requirements.
Technical information[edit | edit source]
| Location | Germany |
|---|---|
| Modulation | AM |
| Audio bandwidth | 5,5 kHz |
| Transmitter | DIY generic AM transmitter (Germany)
Boatanchor transmitter (Wooferton, United Kingdom) |
| Antenna system | Germany:
18 m vertical antenna (75 m band)
Yagi 5-Element ( 60 m band) |
Transmitter power[edit | edit source]
Approximate transmitter power varies depending on the operating frequency.
| Broadcast Band | Power |
|---|---|
| 75m | 50 kW |
| 60m | Approximately 10 kW (occasionally higher)
250 kW from Wooferton, United Kingdom |
| 49m and 43m | 250 kW |
Programming[edit | edit source]
Radio Astra primarily broadcasts:
- Music
- Experimental transmissions
- Technical tests
- Special broadcasts
Programming schedules are most of the time irregular and may vary depending on propagation conditions and station activity, but the station main activity is always around 1200 UTC to 0100 UTC, or even sometimes multiple days.
- Sometimes the station also relay other stations such as Radio60, Mystery For Joy and more...
