Congratulations to 10-yr old Nikilesh Kashyap (and proud papa Raajesh!) on passing his Technician’s License at Milford’s testing site. On 1/16/18 Nikilesh was given the call sign KE8IPE and has already made contacts and checked into the Newcomers and Elmers … Continue reading
Last time around I introduced some ideas on working LF and VLF bands, and in this article I discuss some antenna designs which can be effective for making the most of these big signals.
While working from home on Monday, I turned on the 2-meter, and heard a very interesting conversation.
I find myself becoming more and more interested in chasing some of the experimental stations and beacons which reside down in the 200-500kHz portion of the band, as well as signals in the 136kHz band. This might sound odd for someone who … Continue reading
In last month’s episode I explored the genesis of the first song uttered by a computer, Daisy Bell, and how that song ended up in 2001: A Space Odyssey. In this last installment on the history of speech synthesis I’ll track the … Continue reading
As a kid I tried to learn about electronics the old fashioned way – tear something apart and try to put it back together. Unfortunately I did not have someone overseeing myexplorations, and so very little was actually learned! If … Continue reading
Speech synthesis confers a number of benefits to technology end users. It allows individuals with impaired eyesight to be able to operate radios and computers. For those who cannot speak, and who may also have trouble using sign language, speech … Continue reading
Six, seven, and eight, three numbers that aptly define the 2017 National ARDF Championships held between July 31st and August 6th in the Cincinnati and northern Kentucky areas. To elaborate, there were six parks used for training and competition events, seven … Continue reading
One of the things which makes the radio hobby so pleasurable for me is how easy it is to find interesting things to listen to on whatever radio happens to be handy. From the cheapest AM-only radio to the fanciest … Continue reading
This installment continues the exploration of the development of speech synthesis.
By now I trust those of you who read last month’s column have gotten a taste for learning about propagation and have put some of this new knowledge to good use! Armed with numbers such as the monthly MUF (maximum usable … Continue reading
Another interesting article sent over by Robert AK3Q, about security and the return to HF radio. Task Force (CTF) 75 successfully completed communications systems tests using HF radio waves to broadcast voice and data 6,050 miles from Naval Base Guam to … Continue reading
Robert AK3Q has shared a very interesting link about the return of ground based radio navigation due to possible cyber attacks. South Korea, the US and others are looking into reinstating the Loran system (now updated to ELoran) as a … Continue reading
This edition of the Music of Radio continues to explore developments around electronically generated speech. Homer Dudley, an engineer and acoustics researcher who worked for Bell Telephone Laboratories (BTL), made significant contributions to this field beginning with his invention of … Continue reading
Last time around we looked at Radio Monitoring during WWII from the British side of things. This time we will look at some of the contributions made by America, which were by no means insignificant!
During the weekend of July 22, 2017, Slow Scan TV images were being transmitted from the International Space Station. This commemorated the 20th Anniversary of ARISS, and images of past and present ARISS activities were transmitted.
Who doesn’t remember changing their voice as a kid by talking into a fan? Or sneaking off with baloons at a party or dance to inhale the helium and try to talk like a character from a cartoon? One year for … Continue reading
If one wants to get serious about the radio hobby there comes a time when the study of propagation (or how signals get to where they’re going) is a must. Not only will understanding some basics about propagation make listening opportunities more … Continue reading
Radio counterintelligence during WWII is a topic of great interest to me, not only for the historical relevance, but also for the modern-day relevance. While it might almost seem unbelievable, shortwave (and likely amateur radio) are still being used to … Continue reading
This past weekend, we enjoyed one of the best Oh-Ky-In Field Day events I can remember.
