I have some interesting news for all of those Belka DX fans, Alex the guy behind this magnificent receiver has just announced the introduction of a new model. Ok so it is still called the Belka DX but it has now got a total frequency coverage of 100KHz to 31MHz so those that have put off buying because of lack of Long wave and Medium wave have now had their prayers answered. There has been no fanfare announcement about this but they have just updated their website with the new added frequency range. I am just waiting for the first review to appear before committing my hard earned cash.

Excellent news. I’m sure this will make the Belka DX even more popular than it already is. I have to assume a ferrite bar hasn’t been added (there isn’t much room for one in the Belka series) so you would need to pair a proper MW/LM antenna antenna in order to fully take advantage of the new bands.

Excellent Nick! Thank you so much for sharing this and for demonstrating some weak signal work. You were certainly pitting the Skanti against some benchmark performers!

Tom – someone posted this week a rarely seen 1986 commercial for Eveready Batteries featuring the GE World Monitor radio (and Gold medal Olympic gymnast Mary Lou Retton!)
Thank you so much for sharing this, Robert. I have a special affinity for my GE 7-2990A as it used to belong to my dear friend, Michael Pool (The Professor). It’s quite a workhorse of a radio with excellent mediumwave chops and it packs some amazing audio fidelity. Of course, with the right batteries, it’ll keep you on the air for weeks or months at a time! 🙂
An intracellular antenna that’s compatible with 3D biological systems and can operate wirelessly inside a living cell.
A new study could allow scientists to create cyborgs at a cellular scale, thanks to MIT Media Lab for designing a miniature antenna that can operate wirelessly inside a living cell. This could have applications in medical diagnostics, treatment, and other scientific processes because of the antenna’s potential for real-time monitoring and directing cellular activity.
Scientists named this technology Cell Rover. It represents the first demonstration of an antenna that can operate inside a cell and is compatible with 3D biological systems.
Deblina Sarkar, assistant professor and AT&T Career Development Chair at the MIT Media Lab and head of the Nano-Cybernetic Biotrek Lab, said, “Typical bioelectronic interfaces are millimeters or even centimeters in size and are not only highly invasive but also fail to provide the resolution needed to interact with single cells wirelessly — especially considering that changes to even one cell can affect a whole organism.”
The size of the newly developed antenna is much smaller than a cell. The antenna represented less than .05 percent of the cell volume in research with oocyte cells. It converts electromagnetic waves into acoustic waves, whose wavelengths are five orders of magnitude smaller, representing the velocity of sound divided by the wave frequency — than those of the electromagnetic waves.

We’ve all heard the iconic recordings from the Apollo missions. But how exactly does NASA manage to run live audio between Earth and the moon? And how might we chat with astronauts on Mars and beyond? Featuring Astronaut Peggy Whitson, NASA Audio Engineer Alexandria Perryman, and Astrophysicist Paul Sutter.
Australia’s communications regulator ACMA has asked radio amateurs to comment on their proposed amateur class licence and considerations for higher power 1 kW operation
The ACMA say:
Following the extensive 2021 public consultation and associated response to submissions, we have released a consultation paper on the proposed amateur class licence and supporting operational arrangements, along with considerations for higher power operation. This is the next step in our review of regulatory arrangements for the operation of non-assigned amateur stations.
The draft class licence for amateur radio has been amended to incorporate changes suggested by representative bodies, amateur radio clubs and individual amateurs during the 2021 consultation.
Questions about the consultation
If you have an important question about this consultation, please send it directly to [email protected]. Please note, we may use the Amateur radio update e-bulletin to answer frequently asked questions.
In the late 1950s television networks ruled the airwaves from 7 to 11 PM, but outside of that timeslot television was live, local and unpredictable.
Jim Hanlon, W8KGI, worked as a summer relief engineer at Cincinnati’s WCPO-TV from 1956 to 1958. At that time WCPO-TV did not have any video recording technology, so all local TV was live TV and provided a refreshing dose of live programming, equipment failures and production creativity that been lost in today’s pasteurized, homogenized TV ecosystem.
Join Jim as he recalls what it like producing live TV programming in the early days of television broadcasting.
Hi SWLing post people worldwide, this weekend WRLD takes to the air in the imaginary station series. The transmission will be on air on 9395 kHz from 2200 utc on Sunday 2nd October 2022 via the services of WRMI. Expect some wonderful tunes from all around this magical globe of ours. Fastradioburst23.
Thanks for sharing this, Dan. Seems the seller is also accepting offers (asking price is $999.99 US). Any serious buyers should read the seller notes. The unit looks incredibly clean cosmetically, but would likely need a good electrical going-over and possible alignment.
Even if, like me, it’s not in your budget to purchase a rare radio, I think we can all appreciate the photos:
Thanks again for sharing, Dan!
