Description

The Yaesu FRDX-400 is a double-conversion HF receiver from 1967, serving as the receiver half of a station built around the matching FLDX-400 transmitter. It covers the 160 to 10 meter amateur bands across eleven switchable ranges; additional optional ranges included extra 10-meter segments, a CB range (26.9-27.5 MHz), and a WWV time-signal range. A closely related version was sold in Europe under the name Sommerkamp FRdx-500.
