Hallicrafters SX-122 Communications Receiver (1962)Phil's Old Radios:::Hallicrafters SX-122 Communications Receiver (1962)This Hallicafters SX-122 was my very first 'boatanchor,' the name affectionately givento heavy old communications receivers. I bought this one in the mid-1990s.After collectingtabletops, portables, and transistors for years, I foundmyself bitten by the boatanchor bug one day.

Reading Chuck Dachis'Hallicrafters book had something to do with it. It's hardto look at all those great old beasts for very long,without wishing that you had one of your own.Listening to shortwave broadcasts was a biggerfactor. During the previous year, thehad become my favorite bedside set. Ispent many a pleasant late-night hour turning its dial to findstations all around the world.Although the 3000 is a good performer,it still had a silicon heart, and I was itching to listen to worldband radioon a genuine 'glow powered' tube set. With eleven tubes inside,the SX-122 definitely has plenty of glow power, yet it's modernenough to give very nice performance.DescriptionModel SX-122 was made from 1962-1964 and it was the top-of-the-line Hallicraftersset of its day. The SX in the model designation indicates that it has a crystal filter, a feature shared by my other high-end Hallicrafters sets (, and ).This radio has four bands, covering frequencies from.54-1600 Khz (the standard broadcast band) and 1.75-34 Mhz (shortwave and amateur).As you can see from the first photo, this radio is in excellent cosmetic condition. On top of the radio is a matching model R-48 speaker,which I acquired a couple of years after buying the receiver.Theseller told me it was used by a German lady who came to the USA.Evidently, she used it only to listen to German shortwave broadcasts.

There is virtuallyno wear around the dials, as you'd find if it had been used by a real 'dial twister.' This is a dual-conversion receiver, meaning that it has two intermediate frequency (IF)stages at 1650 Khz and 50 Khz. Most consumer radios have a single IF stage. Additionalcircuitry lets you listen to amateur CW and SSB broadcasts.The tubes are: 5Y3GT (rectifier), 0A2 (voltage regulator), 6DC6 (RF amplifier), 6AU6 (1st mixer),6C4 (variable oscillator), 6DC6 (1650 Khz IF amplifier), 6BL8 (2nd mixer/crystal oscillator),6BN8 (AVC amplifier/AVC rectifier/AM detector), 6BE6 (BFO/product detector), and6GW8 (audio amplifier/audio output). The set also features anoptional crystal calibrator, which takes a 6AU6 tube if present (mine is not). The crystal calibratorgenerates marker signals at every 100 Khz on the dial for checking the tuning accuracy.The large left dial is the main tuner and the right dial is the bandspread, which allowsfiner tuning.
