This is a WebSDR receiver located in Grimsby, operated by Matt. Big thanks to Barney for helping me get this site up and running. Email:

Using a Nooelec RTL Dongle with Nooelec v1.3 upconverter connected to a wellbrook loop antenna facing 140° South East / 320° North West.

Using another Nooelec RTL Dongle with v1.3 upconverter connected to a Sony AN 1 Whip For 9mhz & secondary Loop Facing East/West for LW/MW Reception.

You can widen the filters to gain better sound quality and narrow them to avoid adjacent qrm.

Greatest hits is on 1161khz, Absolute:1215(better on West loop), Talksport: 1053, BBC 5 live: 909 or 693, BBC R4 198.

The Mobile version of this site can be found here

Tip For Mobile users: If you directly enter the frequency 20khz on the mobile site you can tune MW/LW via the E/W Loop: To get back to the SE/NW loop enter the frequency 2100khz and then tune around.

More info can be found at the bottom of the page.
