It receives from 540 KC to 31 MC in 6 bands. Bandspread for the 80, 40, 20, and 10 meter bands is calibrated and appears on a separate dial. This is an excellent receiver for general

Hammarlund had introduced their land-mark Super-Pro in early 1936, but it's $400 price tag made it inaccessible to most of the amateur-radio and short-wave-listening markets. With the HQ-120, introduced in December, 1938, Hammarlund engineers succeeded in slashing the price by two thirds, while retaining most of the important features of the Super-Pro, and introducing others to make the set

The amateur line, however, included the HQ-120X. The difference between the HQ-120 and HQ-120X is the crystal filter. As time progressed, HQ-120s were phased out, and all HQ-120's were sold in the 120X configuration. This receiver has been recapped, and has had out of tolerence resistors replaced, and has a new tube compliment.

Hammarlund HQ-120-X CW/AM Receiver. My Hammarlund HQ-120-X was a 2002 Christmas present from my Elmer Milt Moratis W3XX (ex K3AMI) of Pittsburgh PA. Thanks Milt !! I clearly remember that summer day back in 1973 when at age 15 I rode my 3 speed Stingray bike to Perrysville Elementary School, where Milt was the principal, to take my Novice Exam!!
