About

Aacharya J.C.Bose is well known as the “Father of Wireless Communication”.

Acharya Bose’s demonstration in 1895 & 1897 predates all.

Bose transmitted wireless signals to a distance of a mile. Popova in Russia was still trying remote signaling at this time & the first wireless experiment by Marconi was not successful until May 1897.

Bose is a pioneer in microwave optics technology.

Bose’s invention of 1-centimeter to 5 millimeters radio waves is being used in radars, satellite communication& remote sensing.

Bose’s concepts from his original 1897 papers are now incorporated into a new 1.3 mm multi-beam receiver on the NRAO (National Radio Observatory) 12 Meter Telescope.

Bose anticipated the use of P-type& N-type semiconductors & hence 60 years ahead of his time. Bose developed the use of GALENA crystals for making receivers.

In Bose’s presentation to the Royal Institution in London in January 1897, he speculated on the existence of electromagnetic radiation from the sun. This radiation from the sun was not detected until 1942.

Video: Exploring a 1 MILLION Watt FM Tower (YouTube)

My Dad and I took a road trip to tour the 1 MW FM community tower in Crestwood, MO, serving the entire St. Louis metro area combining 10 FM radio signals into two antenna systems.

Special thanks to the Audacy engineers who allowed us to take a peek at their (very clean!) transmitter rooms and equipment!

How the Cassette Tape Helped Create the Internet (WNYC Studios)

In 1983, Simon Goodwin had a strange thought. Would it be possible to broadcast computer software over the radio? If so, could listeners record it off the air and onto a cassette tape? This experiment, and dozens of others in the early 80s, created a series of cassette fueled, analog internets. Our friend Simon Adler at Radiolab reports.

This is a segment from our November 26th, 2021 program, How Cassette Tapes Changed the World. [Read and listen to this piece at WNYC Studios…]

Commercial Radio Is 100 Years Old. Can It Survive? (Inside Hook)

Four industry veterans weigh in on how they’d “fix” a medium that remains popular but lacks innovation

The first broadcast from a commercial radio station took place on November 2nd, 1920. Here’s how I imagine listeners responded to the debut of KDKA-AM in Pittsburgh:

Nov. 2: This is amazing! I can hear someone from hundreds of miles away talking through this device! The world will never be the same!

Nov. 3: They’re playing “Wang Wang Blues” again already?

The joke here is twofold: First, there’s a popular song called “Wang Wang Blues” from 1920. And second, by day two, KDKA had already developed the repetitive play-the-hits format that would become one of its hallmarks for the following century.

The first commercial broadcast actually related to the election — it was the idea of a radio manufacturer, Westinghouse, to offer up programming to go along with their newfangled tech (a century later, Apple and Sonos thought exactly the same thing). The first commercial broadcast featured updated results of the Harding-Cox presidential race “before [people] read about it in the newspaper,” as this PBS retrospective notes.

One hundred years later, commercial radio still holds a place in American daily life. The average American still listens to about 106 minutes of radio per day (with the coronavirus and its attendant lockdowns projected to increase that number), and there are more than 15,000 stations in this country alone.

We’re certainly listening to radio differently: according to Statista, 57% of Americans do so online, whether by streaming, downloads, satellite or digital radio. If you asked me how I listen to radio, I’d offer up services like Apple Music 1, Sonos Radio and Dash Radio; podcast downloads from ESPN Radio; online streaming of overseas entities like BBC 1 and Triple J or any occasional college station like WSOU; NPR stations for news and commentary (and music if it’s KCRW); and for new music, a DJ-free experience via Spotify’s New Release Radar playlist. In other words, while audio-only, passive-listening medium has survived and thrived for a century, which is astounding and worthy of celebration, the need for traditional, turn-the-dial “commercial” radio is decidedly on the wane.[]

20th anniversary of first ham radio operation from ISS (Southgate ARC)

On November 13, 2000, the ISS Expedition-1 crew turned on the ARISS Ericsson radio for the first time and completed several contacts with ARISS ground stations around the world to validate the radio communications system

These inaugural contacts launched an incredible two-decade operations journey on ISS, enabling ARISS to inspire, engage and educate our next generation of explorers and provide the ham radio community a platform for lifelong learning and experimentation.

In celebration of the ISS 20th anniversary, ARISS was part of an ISS Research and Development Conference Panel session entitled “20 years of STEM Experiments on the ISS.”  The video below, developed for this panel session, describes our program, celebrates our 20th anniversary, conveys some key lessons learned over the past 20 years and describes the ARISS team’s vision for the future.  Enjoy watching!

20 years of continuous operations is a phenomenal accomplishment.  But what makes it even more extraordinary is that ARISS has achieved this through hundreds of volunteers that are passionate in “paying it forward” to our youth and ham radio community.  On behalf of the ARISS International team, I would like to express our heartfelt thanks to every volunteer that has made ARISS such an amazing success over the past 20 years. Your passion, drive, creativity and spirit made it happen!!

Congratulations ARISS team!!!
