  Noise limiter, bandwidths 6 and 0.1 - 3 kHz by mans of Q multiplier circuit.
  Optional XC-455 crystal controlled BFO for USB/LSB reception (16 US$), optional XC-100 crystal calibrator (18 US$), only one of them can be installed within the cabinet; optional clock / timer (Unit with timer sold as HQ-100C), optional S-100 external speaker. The BFO used the Q multiplier au to serial # 1199, from serial # 1200 there was a separate BFO added. There was also a separate BFO kit for retrofitting the earlier sets available. See also HQ-100a with and without 5Y3 rectifier and another HQ-100A for 1962-1964 with HQ100A spelled out on the front panel. Hammarlund used a 5y3 rectifier in the early run and at the tail end switched over to the solid state rectifier as Hammarlund was using at the same time in the Hq 170a's & the Hq 180a's. Those with the solid state are VERY rare.
