A must for all serious minded Vintage Wireless enthusiasts.  www.vintageradio.co.uk  Web Site is run by the The Vintage Technology Centre incorporating 'On The Air Ltd.' As the name implies this site is a professional one, nevertheless its contents are regularly updated and easily sorted for seeing what is what and what may be available from time to time. The coloured pictures of various vintage wireless and other goodies are well worth while for identification purposes or pure nostalgia.  An interesting magazine called 'Air Waves' is published bi-monthly for a modest subscription and in my opinion very useful for valuation purposes.

 A great site for keeping in touch with what the sun is doing  Spaceweather.com has current data on sunspot activity and links to pages with pictures from SOHO the orbiting solar observatory hardware. Well worth a visit if you have any interest in how solar activity effects the earth  and users of the electromagnetic spectrum in general.
