![[Hammarlund_HQ150.jpg]](HQ150.jpg)
This is the last of Hammarlund's large single-conversion general coverage receivers and is similar to the HQ-120X, HQ-129X, and HQ-140X with the addition of a Q-multiplier and 100kHz crystal calibrator. A review article can be found in QST magazine, December 1956.
