Some UK HF Trading receive sites have been identified by a search of planning applications in the vicinity of the London data centre located in Slough. The ones shown in bold have antennas that can be seen on Google Earth.

I would think that there are similar sites around Frankfurt in Germany, but these have not yet been found.

Hi Ray,

The KiWi's at Weston do have their GPS enabled, but by default this is run as a background task and sometimes if the KiWi's are busy the GPS acquisition will be 'paused' until there are less users on the KiWi.

As an experiment I have changed the GPS settings on my KiWi which is co-sited at at Weston, to see if this helps to improve the frequency accuracy.

Please try http://websdr.uk:8060/ and let me know via the owner / admin link that can be found in the yellow tabbed 'stats' pane if you are still seeing significant frequency errors, or any other problems.

Regards,

Martin
