The pages were added over the years primarily because I have an interest in the subjects. When available, additions and updates will be made.
In most of the leading British radio magazines, notably Practical Wireless and the Short Wave Magazine, 'H.A.C.' Short-Wave Products ('H.A.C.' = Hear All Continents) advertised up to the early 1980s with simple shortwave receiver kits.
In this section is posted the history, technical description and operational use of the Fullerphone, a unique and not very commonly known DC Morse line telegraph set. Explained is how this simple, but ingenious little set solved the problems of overhearing and enabled communication through long and leaky field lines.
A Russian type CH4-1 frequency meter set was examined and compared with its USA predecessor, the BC-211, part of SCR-221. See how the Russians followed very closely the USA design of 1942. More Russian radios are posted in the Image Directories.
In children's books in the period 1920 to the 1960s, the main subject was often radio and television. In this section are front cover illustrations and descriptions of a selection of Dutch boy's books which had one thing in common: they were thrilling and still most enjoyable to read!
‘Mobile Radio in the Netherlands’ is a brief description of the history of the company department I have work for until my retirement. Only the period from the pre-war start to the 1980s was dealt with, and no attempt were made to describe later periods of modern cellular and other systems.
The evolution of Air-Sea rescue transmitters with many pictures, circuit diagrams and technical data in three parts from World War 2 to the 1980s.
Although not widely known, the Swedish Army signal service used a varied and interesting range of radio equipment over the years. Particularly the war-time sets were ahead of their time.
The ‘Other Topics’ pages below have no direct connection with the main topic of the site: the technical history and development of British Army radio communication.
Small operator lamps were issued with most British (and Commonwealth) Army vehicle and ground radio stations, normally powered directly from a socket fitted on the front panel of the set. This overview shows the presently known versions and variations. Please note that it is also available as a PDF on the download page.
Quite a number of years ago an SSF Mk.II transmitter-receiver was donated to the Amateur Radio Museum ’Jan Corver’, located in Budel, The Netherlands. At that time nobody could identify the set and its function, and up to the present day it remains to be a mystery.
Key and Plug Assemblies were essential parts of most British (and Commonwealth) Army wireless sets and stations. This overview shows the currently known types and versions of these Morse key assemblies, spanning the period from the late 1930s until the 1950s when the Larkspur range of equipment started coming into service.
