My first good communications receiver, around 1959, was a Hallicrafters SX-99. Not the best, but a good value for its price.
A few years later, Hallicrafters had not brought out anything better at the "top of the line" so I moved to a Hammarlund H!-180, later replaced with a Collins R-390A. By the mid-60, the Hallicrafters receivers were no longer at or near the top of the line. However, in about 1965 I bought several Halliicrafters fixed frequency FM receivers for the transmitter end of my station's STLs, and they were great radios!
