Very, very cool! What I wouldn’t give to travel back to the CES shows of the 1970s and 80s.
According to the Levono blog, the 1970 CES was when the VCR made its debut. Amazing.
Thanks again, Bob.
I’m curious if any SWLing Post readers have attended the CES in past decades. I really wanted to attend CES in the 1990s, but since I was a university student half of that decade, I never had the funds (or justification) to do so!
Yesterday evening, I warmed up my Signal Corps BC-348-Q and tuned to 9,420 kHz to see if the Voice of Greece happened to be on the air.
Fortunately, I was rewarded with a strong signal from Avlis.
The ‘348 did a fine job playing all that lovely Greek music, too. Though the WWII era ‘348 was never intended to be an HF broadcast band receiver, when paired with a good speaker, it sounds pretty darn amazing!
While certainly a promotional piece for Hallicrafters, this has great footage and captures a bit of the excitement of radio expanding into new frontiers. There is a discussion of how the radio was modified for military conditions as well as some innovations which were implemented to make such a system mobile.
As an aside, it never ceases to amaze me how clear and crisp black and white film technology of the time seems somehow better than the color images which replaced it. But that may just be me — a black-and-white guy living in a colorized world!
There is a second part to this video, as well as other WWII-era videos available on YouTube with a bit of searching, and of course don’t forget to check out the SWLing’s Shortwave Radio Archive page for more interesting shortwave audio old and new!

Many thanks to SRAA contributor, Tom Laskowski, who submits the following notes with his timely off-air recording of the BBC World Service from January 28, 1986:
Thirty years ago today the US Space program came crashing down with the explosion of the Space Shuttle Challenger.
I was a student at Purdue University at the time, living in a dormitory.
I decided to make some recordings knowing this would be a historic event.
This is a recording I made of the BBC on the evening of Jan 28 (0200 UTC on January 29). The frequency was most likely 5975 kHz or 9590 kHz. The dorm environment didn’t make a great place for SWL reception and the recording is noisy but still of decent quality.
Recorded using a Sony ICF-2001 with a wire attached to a window screen for an antenna.
A radar site considered by some to be as historically important as Bletchley Park will be preserved, thanks to a £1.4 million ($2 million) grant from the UK government. The Bawdsey facility in eastern England, established in 1938, was the world’s first operational radar station. The then-brand new technology helped the allied forces win the Battle of Britain, and some historians think it may have shortened World War II by as much as two years. The facility was closed in 1991, and is on Britain’s “at-risk” heritage list because of structural issues and water damage.
According to the preservation group Bawsdey Radar, construction work will start in September 2016 and the building will open to visitors in September 2017. The goal is not just to conserve it, but also to unveil a new visitor exhibition featuring physical and virtual displays. The UK’s “Heritage At Risk” adviser John Etté said the facility “played a vital part in the development of radar technology during [WWII], and had a huge impact on post-war electronics and defense system,” including GPS, water technology, radar guns and the microwave oven.[…]
