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 East/West for LW/MW.

Using another Nooelec RTL Dongle with v1.3 upconverter connected to a Sony AN 1 Whip For 48M and omnidirectional LW/MW Reception.

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

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 (good for local signals)

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 simultanious users. Total server downtime was around 4 hours.

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