SWLing Post reader, Jeffrey Fritz, sent me the following message and has kindly allowed me to share it with other readers. I’mthoroughly inspired!
As a teenager in the 1960s I spent a considerable amount of time SWLing on a Hallicrafters SX-110 communications receiver. I collected QSL cards from all over the world and loved being an SWL.
The SX-110 was purchased on 9 September 1961 from Gem Electronics in Farmingdale, Long Island, New York. My parents bought it for me, probably after a great deal of whining and cajoling on my part. Although much of my gear has long since been sent to some landfill by my parents, like my precious Lionel trains, I would not allow them to trash the SX-110.
The radio has been sitting in one basement or another, unused for the better part of 30 years.
Yesterday I decided to try bringing the radio back to life. Restoring this kind old receiver was a labor of love. The receiver was carefully looked over and tested with a VOM for bad components and the top of the chassis cleaned as best I could. The bottom was pristine. I just needed to clean out a few cobwebs and replace the power cord.
After being cleaned up and several components tested, the SX-110 was slowly brought back to life on a Variac. I started at 10 volts AC and slowly increased the voltage every ten minutes by another ten volts. When I got to about 90 VAC, I could hear static and distorted audio coming out of the speaker. It was a good sign that the radio would come back to full operation once I reached the normal 110 VAC input–and that is exactly what occurred.
I am happy to report that, with a little patience and love (and a good cleaning) –and with three of the original Hallicrafters tubes still in place, my trusty old Hallicrafters SX-110 shortwave receiver is happily working today. I have it connected to its original Hallicrafters R-47 3.3 ohm speaker.
Yesterday evening I listened to Radio Taiwan, Radio China International, Radio Havana Cuba, The Voice of Turkey and The Voice of Russia. The audio quality was rather decent without a hint of AC hum. The radio is probably due for a good alignment. I am running the radio on the Variac set at 110 volts AC and will probably keep it on the Variac because the AC voltages today in the U.S. are significantly higher than they were in 1961.
Even the XYL thinks that the radio sounds terrific! What better recommendation can there be for this old, vintage receiver?

PS–Jeffrey also mentioned to me: “If you look closely at the chassis stamp photo of the SX-110, you can see a stamp that reads ‘199117 C.’ This is the manufacture date of the receiver. The fourth digit is the year, and the fifth and sixth digits are the week of the year. So, 199117 is the 17th week of 1961 or the week of 23 April 1961.”
Very interesting. Now I need to examine a few of my own Hallicrafters receivers…
