Spectrum Communications was established as a part-time business by Tony Nailer in October 1978.  In August 1981 following the legalization of CB in the UK there was sufficient work and CB sales for both Tony & wife Jean for full time employment.  CB popularity declined steadily to a very low level by about 2000 and for the following 4 years sales were almost at unsustainable levels.  Following becoming an author with PW in 2004 and developing new projects for the Doing It By Design series, sales have risen back to make us busier than ever. In 2005 I became author of another PW series titled Technical For The Terrified.  G2DYM Aerials was purchased for Richard Benham-Holman on 30 October 2006.  In March 2010 the first 27 articles of Technical for the Terrified was compiled into a book of the same name.  Since 2010 we have steadily expanded our stocks of specialist RF components and now half the orders are for component parts.  About 50% of orders are for export. Garex Electronics was purchased from Peter Longhurst on 1 December 2011.
