H.A.C. Short-Wave Products kits

Introduction


In most of the leading British radio magazines, notably Practical Wireless and The Short Wave Magazine, 'H.A.C. Short-Wave Products’  advertised up to the early 1980's with simple and inexpensive short wave receiver kits for the beginning listener. Always being intrigued by H.A.C. Short-Wave Products and their kits, I recently found (only by accident) circuit diagrams of the H.A.C. Model K and Model DX receivers.

This web page is an appeal for more information in the form of documents, circuit diagrams, catalogues, and photographs of any hardware such as chassis, coils and tuning capacitors. Please contact me if you have something interesting to add to the H.A.C. pages.

I am also interested in any articles which might have been published on this subject. All presently known information on the H.A.C. Short-Wave Products kits, in pictures but also in printable downloads are posted here.

The H.A.C. pages on this site gradually grown over the years chiefly by kind contributions in the form of scans and photographs. It is difficult to estimate to how many people a H.A.C. kit was a stimulation to the start of a career in radio or electronics.
