Hallicrafters called their HT-4 “a new conception of transmitter design, a distinct departure from the traditional” rack-and-panel designs common in that era. It could be set up to switch among any three bands from 80 through 10 meters. Power output was 450 watts CW, 325 watts AM phone.
The first 82 pages of the February 1944 issue of Radio News are largely devoted to the SCR-299. Ads on these pages are from the many manufacturers that made components for the unit, as well as for Hallicrafters itself.
