ECLECTIC AETHER - Adventures with Amateur Radio


I'm sorry that my website hasn't been updated much recently.

There are problems with the web editor interface and updating existing pages is problematic.


I run the WEB SDR IO group which is primarily aimed at WEB SDR admin's and owners with the aim of sharing experiences and technical expertise relating to operation and running of WEB SDR's - https://groups.io/g/websdr

I'm one of the Admins for the SUWS WEB SDR  - http://websdr.suws.org.uk/ 

I also operate a number of KiWi WEB SDR's which cover the 0-32MHz frequency range
