Comments: The 840A has basically the same circuit as the 840, but in a very different cabinet. Ranges: .48-1.14, 1.4-3.8, 3.7-10.6 and 10.5-30.6 MHz. The dial frequency readout is not too accurate. However, the logging scale allows you to quickly and accurately return to a previously heard frequency. Audio quality is good. Features an oyster gray hammer finish metal cabinet. The amateur bands are marked in blue and the broadcast bands in red.
