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

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 48M. & 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.

Local greatest hits station Viking 2 is on 1161khz, Absolute:1215(better on West loop), Talksport: 1053, BBC 5 live: 909 or 693, BBC R4 198.

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 N/E loop enter the frequency 2100khz and then tune around.

Update: 23-06-18: Added a second loop facing West, this is good for RTE 252, BBC 198 & 909 and Absolute 1215.

Update: 19-06-18: Local Absolute Radio Transmitter on 1215 was switched off just after 11.03AM, 1215 is now better on the West facing loop as the signal comes from Huddersfield.

Update: 14-09-17: Built a new PC just for hosting the websdr with 4GB ram and a AMD 6400 3.7ghz dual core processor. Server can now handle 80 simultanious users.

Update: 14-09-17: Added LW/MW Via omni directional whip antenna

Update: 25-06-17: Added 48M shortwave, but I can not do much about the local QRM sadly:(

Update: 22-05-17: Changed the acer laptop that I first used to set up the WebSDR that kept freezing for a used HP DC-8000 mini desktop, the server can now handle 40 simultaneous users. Total server downtime was around 4 hours.

November 27th 2016, WebSDR first came online hosting just the LW/MW Band via an Acer Laptop.
