This 5 MHz WebSDR receiver is located in Wells, Somerset, England and is operated by Ian G4FSU

The receiver is a FUNcube Dongle Pro+ with an RF bandwidth of 192 kHz running on a Raspberry Pi 2. The antenna is a Wellbrook loop feeding this receiver and an SDR-IQ on RemoteSdrServer and SDR-Radio Server.

This SDR covers most of the amateur 5 MHz allocation (UK frequencies in blue) and some common frequencies (USB unless noted) are displayed below. Click the label on the waterfall to tune the receiver.

5262.0 kHz is the CW QRP centre of activity in the UK
5278.5 kHz is used by Raynet for emergency communications. Scheduled nets are on the 7th & 21st of the month at 14:00 or 20:00 (UK local)
5290.0 kHz several beacons operate on this frequency
5317.0 kHz is used for AM actvity
5330.5 kHz is a spot frequency for many countries but not the UK
5351.5 - 5366.5 kHz is the worldwide WRC-15 allocation. 5354 kHz, 5357 kHz, 5360 kHz, 5363 kHz are common frequencies
5371.5 kHz is one of two common frequencies between the US and UK
5398.5 kHz is a popular frequency, carrying the GB2RS news service at 16:00 (UK local) on Sundays, and often used for SOTA activity
5403.5 kHz is a common frequency to many countries so often has amateur activity. US stations can be heard when the Atlantic is in darkness
5450.0 kHz Military 1 is an RAF Volmet station normally audible from here and so makes a useful propagation indicator

More details on amateur radio operation on 5 MHz in the UK can be found at http://rsgb.org/main/operating/band-plans/hf/5mhz/.

Non-amateur signals are most likely STANAG data government or military stations, although USB can sometimes be heard. These frequencies are also often used by fishing boats, although there is no maritime allocation here so these transmissions are not legal.
