Listen Monitor Decode Online VLF LF HF signals with our GPS locked KiwiSDR located in Bucharest/Romania/Europe (KN34CM)
This is a powerful software-defined radio (SDR) tool that provides real-time access to the radio spectrum. Here are some of the exciting things you can do with it:
- Listen to international radio stations: Shortwave (SW), medium wave (MW), and longwave (LW) from around the world.
- Monitor amateur radio bands: Observe activity on popular bands (e.g., 20m, 40m, 80m).
- Decode digital transmissions: NAVTEX, WSPR, FT8, Weather FAX, SSTV, LORAN, DRM, HFDL, ALE 2G, IBP, CW, and more.
- Explore natural signals: Detect electromagnetic phenomena like lightning strikes or magnetospheric "whistlers" in the ELF/VLF range.
- Receive time synchronization signals: Track atomic clock broadcasts (e.g., WWV, DCF77).
- Conduct scientific research: Analyze geomagnetic or ionospheric activity using radio signals.
- Locate radio interference: Identify sources of natural or artificial interference.
- Calculate directions of signals: Using TDoA plugin from KiwiSDR.
- Educate and learn: Study wave propagation, signal processing, or the Doppler effect.
- Collaborate globally: Share your KiwiSDR or use remote receivers to explore global signals.
With a KiwiSDR, the possibilities are endless for radio enthusiasts, researchers, and anyone curious about the fascinating world of radio communications!

Note:
- Your web traffic is ENCRYPTED (HTTPS) when accessing our SDR receivers through our domains. This not only enhances security but also allows access in locations where your ISP may be blocking it.
- Unfortunately, there are some RF broadband noises in the area which turns on randomly, but this will be fixed soon as the receiver will be moved into another location.
- The S-Meter on this SDR is calibrated, but it does not show absolute signal strength due to variations in antenna efficiency across different frequency bands. As a result, the S-Meter should only be used to compare relative signal levels, not absolute measurements.
- In the lower frequency range of VLF and ELF (0-5 kHz), the receiver's sensitivity decreases significantly, and the impedance (Z) increases. This is likely caused by insufficient capacitive coupling at such low frequencies. Consequently, below 8 kHz (which is already 3dB lower than 20KHz), signal attenuation becomes more pronounced, increasing exponentially.
