R. L. Drake Commercial Receivers

Robert Lloyd Drake founded the R.L.Drake Company in 1943, which initially manufactured amateur radio accessories. After moving to Miamisburg OH, the receiver 1-A was introduced in 1957 as the first shortwave receiver to cover the amateur radio bands in astonishingly compact dimensions. Around 1960 - 1966, the set was followed by the the 2-A (-C), which also covered only the amateur radio bands. In 1964, the first receiver of the successful R-4 series was introduced, the double conversion set allowed a dial accuracy of less than 1 kHz on the amateur radio and a few broadcast bands, only with the optional frequency synthesiser FS-4, the complete shortwave band was covered. In 1978, the R-7 / 7A covering the entire shortwave range from 10 kHz to 30 MHz followed, it was also produced as mritime communications variants.

Here, in the Commercial Receivers section, the Drake receivers sold for commercial use, primarily in maritime radio, can be found.
