This SDR (Software Defined Radio) receiver offers a continuous reception range between 24 MHz and 1.766 GHz, with an instantaneous bandwidth of 2.4 MHz.
Thanks to the direct sampling mode, it can also receive lower frequencies — starting from 14 MHz, 7 MHz, 5 MHz, 3 MHz, and down to approximately 500 kHz. However, sensitivity in this range is reduced, and the antenna used is not optimized for shortwave signals.
Even so, the variety of signals that can be received is extremely wide — from FM radio stations to satellite transmissions, GPS navigation signals, and aeronautical or maritime communications.
Reception domains and applications:
- Amateur radio bands: 50 MHz, 70 MHz, 145 MHz, 433 MHz, and 1.2 GHz — where local contacts, repeaters, and long-distance (DX) communications can be heard under favorable conditions.
- Satellite communication bands: 137 MHz (NOAA weather satellites), 250 MHz, 400 MHz, 1.5 GHz (GPS, Inmarsat), 1.7 GHz (satellite data transmissions).
- Aeronautical VHF band (108–135 MHz): monitoring air traffic, communications between aircraft and control towers, as well as decoding ACARS and ADS-B (1090 MHz) messages.
- Maritime VHF band: reception of marine communications, emergency channels, and AIS transmissions – although performance may be limited if the receiver is not located near the coastline.
- Land mobile and service communications: monitoring frequencies used in PMR, LPD, DMR, TETRA, or other analog and digital systems within the VHF (146–180 MHz) and UHF (420–470 MHz) ranges.
- GSM bands (uplink/downlink 820–950 MHz): spectral activity analysis and observation for experimental or educational purposes.
The receiver can be used not only for listening but also for real-time radio spectrum visualization, digital signal decoding (FM, AM, SSB, DMR, APRS, AIS, ACARS, FAX, ISM sensors, etc.), and identifying sources of interference.
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.
