Small Companies


There were many suppliers of marine radios, some very substantial with their own pages on this site, but many more that were much smaller, and often short lived. I don't have much information on these, but this list of them is from the Allan Lytel book as augmented with several earlier companies known to me.

While the advertisement below (A HOT LINK) is for one of the larger companies, it is typical of marine radio manufacturers ads of the period. Over the years I collected the 20 ads included in the PDF. These are mostly smaller-company ads but also includes one ad for each of the larger companies. For additional advertisements see this PDF of 19 RMCA advertisements .
