Hallicrafters SX-100 Mark 1A Receiver

Front view of SX-100 Mark 1A Receiver
The Hallicrafters SX-100 receiver was produced from 1955 to 1962.  It sold from $290 - $325 when new.  This is a very nice Hallicrafters SX-100 Mark 1A general coverage communications receiver.   This Mark 1A version is next to last in the production series.  The Hallicrafters SX-100 Mark II was the last in the production series.

Controls included:  Pitch Control, Reception, Standby, Phone Jack, Response Control (upper and lower side band selector), Antenna Trimmer, Notch Frequency, Notch depth, Calibrator on/off, Sensitivity, Band Selector, Volume, Tuning, AVC on/off, Noise Limiter on/off, Band Spread and Selectivity.

The Hallicrafters SX-100 receiver is stable and sensitive and receives AM shortwave signals very well, CW and SSB.  The Hallicrafters R-46, R-46A and R-46B speakers were matches for this receiver.  This is a very nice example of a late 50s early 60s Hallicrafters communication receiver. 
Inside View of SX-100 Mark 1A Reciever
The Hallicrafters SX-100 Mark 1A is a double conversion super heterodyne 14 tube receiver.  It covers from 538-34,000 kHz. The SX-100 included a "Tee Notch" filter, which provides a stable non-regenerative system for the rejection of unwanted hetrodyne.  The "Tee Notch" also produces an effective steepening of the already excellent 50 KC i.f. pass band (made famous in the SX-96) and further increases the effectiveness of the advanced exalted carrier type reception.  It has a plug in 100 KC quartz crystal calibrator, full precision gear drive dial system and a second conversion oscillator crystal controlled (allowing greater stability and additional temperature conpensation of high frequency oscillator circuits).  This receiver is stock and works great.
