This 1956 Radio Handbook has very slight cover wear, features ad for Collins Radio Gold Dust Twins (KWS-1 & 75A-4)
We found this nice 1956 Radio Handbook, our radio tech shelf is full so it needs a new home. These handbooks cover similar amateur radio topics but have new and different material each year. Different projects, different technologies as they come into use. As the handbook is only so large, interesting subjects and materials that are older tech get reduced space, or have to be omitted completely. For that reason I have half a dozen different handbooks myself. they range from early 1930s to the present. For good tube circuits you would certainly want some older ones. For add-ons to use with classic 1970s transceivers, a handbook from the 70s would be nice.
