(4.4/5) Add a review / View all reviews

Desktop Shortwave Transceiver

The DX-SR8 is a base (desktop) HF transceiver with a detachable front panel. Maximum RF-output is 100 watts in SSB or CW. In AM it delivers 40 watts to your transmission line. A 10-digit keypad allows direct frequency entry, band selection and more. IF-Shift is provided along with RIT/TXIT, narrow-filter and noise-blanker to stay away from QRM. For CW operation an electronic keyer unit is standard. The 600 memory channels can be used with diferent scan modes (Priority, Search, Busy, Timed, Memory and Programmed search). A special Super-Low QRP setting is provided (0.1-2W variable).

The Alinco DX-SR8 is sold as the DX-SR8E in Europe and as the DX-SR8T in North-America. The only difference between the E and T models is the extra 5.3 MHz band in the T-version.

A receiver-only version also exists in the form of the Alinco DX-R8.
