Recording Radio Kuwait with the RadioJet’s IF recorder

While playing with the Bonito 1102S RadioJet the other day, I received a strong signal from Radio Kuwait. I thought I’d record the music they were playing, as the fidely was impressive for a signal traveling nearly 7000 miles.

Instead of recording the actual audio of the broadcast with the RadioJet’s AF recorder, I decided to use the IF recorder, which saves and records 24 kHz of actual spectrum. This is an excellent way to record while leaving it unattended. Later, when you review the material, you can refine and shape your recording of an individual broadcast.  Then, if an adjacent signal or some other condition requires you to adjust filters, you can do so just as you would when recording a live broadcast.

Though the file sizes are marginally larger than those the AF recorder produces, it’s not a hard drive-eater like broad spectrum recordings on an SDR.

One more (very cool) RadioJet feature: while making an IF recording, the RadioJet embeds UTC time code in the recording. This way, should you make a recording and forget to note the time you begin it, the time code shows up in the display. The Perseus also does this, and I think it’s a brilliant addition.

Ultimate gift for Dad: A professionally restored Hallicrafters S-20R

The Hallicrafters S-20R Sky Champion

On the subject of being reunited with a special radio, I found this story in the Illinois newspaper, the Quincy-Herald Whig:

For David Nagel of Quincy, it was Father’s Day in August.

The 81-year-old Nagel received an unexpected gift Wednesday night from his son, John, who lives in Texas.

David Nagel had just finished hearing — and taking part in — a discussion about a Hallicrafters S-20R receiver at a meeting of the Western Illinois Amateur Radio Club, a model that had first piqued his interest more than 60 years ago. At the end of the meeting, Nagel was presented with the genuine article — a Hallicrafters S-20R that his son had restored and shipped to Quincy to surprise his dad.

[…]David Nagel said he never thought he would ever own one of the Hallicrafters S-20R receivers again after letting his original model go in the mid-1960s.

[…]Over the past five years or so, John Nagel said, he had heard his father talk about his old radio, the Hallicrafters S-20R receiver and how he wished that he had not traded it in those many years ago.

“I had a great time with that receiver when I was young,” David Nagel said. “It kept me off the streets at night.”

Last year was when John Nagel got serious about trying and find his dad a replacement.

“After beginning to buy and build my own radio setup, last May I found an S20-R receiver listed on eBay,” he said. “I decided to buy the radio and make it a gift to my father. I purchased the radio, had it shipped to a guy in Michigan who restores them. The restoration included the cabinet as well as the inside electronics.”

C.Crane: CC Witness on sale, while supplies last

The C.Crane CC Witness

Though not a shortwave radio, the CC Witness is a very capable AM/FM radio with a built-in digital recorder.  In fact, I know of no other portable with on-board digital recording that receives such stellar reviews. As a result, many medium-wave DXers use the CC Witness while traveling, to capture the sounds of the local radio scene on the go.

For ages, the CC Witness was priced well over $200 US.  Right now, C.Crane is selling their stock of CC Witness radios for $99.95 US.

Clearly, this is an excellent bargain for anyone seeking a very small portable AM/FM radio with on-board digital recording. Note that the CC Witness will also do line-in recordings from other audio sources.

Review: The Worldwide Listening Guide

The Worldwide Listening Guide by John Figliozzi

On the SWLing Post, I write an annual review of the World Radio TV Handbook–a fantastic and comprehensive frequency guide, with a focus on broadcasters and frequencies, though it certainly lacks the programming detail–i.e. content–I so enjoyed in the late Passport To World Band Radio.

That’s where John Figliozzi’s The Worldwide Listening Guide (WWLG) comes in–in short, I think you need a copy in your shack, not to mention, next to your computer.

The Worldwide Listening Guide is like no other frequency/schedule guide you’ll find on the market. First of all, it’s instantly apparent that the author, John Figliozzi, is a DXer, since the book has a spiral bind–which permits it to lie flat when open, and allows the pages to be folded back to take up less table space. A small detail, but important for those of us who want an easily accessible reference in the shack. Figliozzi, moreover, is a noted SWLer, a long-time active member of the North American Shortwave Association, co-host of the annual NASWA Winter SWL Fest in Plymouth Meeting, PA–and did I say, a great guy?

But back to the book: perhaps what makes the WWLG so unique is its comprehensive look at “radio” listening in general, guiding the reader through the many forms radio content now takes:  live, on-demand, WiFi radio, podcasts, satellite, internet, AM/FM and, of course, shortwave radio. He explains the pros and cons of each delivery method and a little about its utility. I thought that I wouldn’t gain a lot from these beginning sections as I’m quite familiar with all of them, but was pleasantly surprised to find all sorts of interesting facts hidden within; no doubt you will, too. Figliozzi also spends a good deal of time time covering the various devices–such as WiFi radios, satellite radios, apps, shortwave radios, portables–that have become indispensable tools of the trade.

Program details like no other

My favorite part of WWLG, and the sections I turn to the most, are those covering programming and content. Figliozzi exhaustively curates more than 4,000 programs sorted by time of day, station, days of broadcast, program types, their frequencies and web addresses. He also sorts the listings by genre:  from the arts, culture and history, to music, sports and more. In fact, he has a well-thought-out list of 34 genres that have helped me locate programming I would have otherwise have never known about. For example, SWLs will find his “Media and Communications” genre listing programming from Allan Weiner Worldwide, Glenn Hauser’s World of Radio and DXers Unlimited to Click and Tech Nation. Each listing tells you exactly when you can catch the program, and where.

What’s also great is the fact that if I find a program I like, I can cross-reference its offering on shortwave–and, if I miss that, I can look up where to find it on demand, on the internet.

A program guide with longevity

I have the 5th edition of The Worldwide Listening Guide–the latest. While I like to have an annual guide, I actually believe this guide will be valid for several years. True, some programming comes and goes–as we’ve seen shortwave stations leaving this year–but, Figliozzi also actively maintains a companion website, The Worldwide Listening Guide Online, which he keeps up-to-date with the latest changes; there is even a blog with his comments and news items. He tells you when to cross out and change listings in your WWLG as programming evolves.

In short, I like the WWLG and have decided that it will become a permanent reference book in my shack, along side my trusty WRTH. There is a surprising amount of information packed into this slim, spiral-bound book. Enough to keep even the seasoned DXer happy for years.

Advances in Software Defined Radios could (will) change our wireless world

(Photo Source: New Geography)

Note that I’m not speaking strictly of the HF spectrum here. But mark this:  a radio revolution is, right now, in the making. ARS Technica just last week published an article entitled, “How software-defined radio could revolutionize wireless” in which the authors argue that software defined radios (SDRs) might not only open the door to new uses for our radio spectrum–uses we can’t currently fathom!–but also open the door to unlimited free innovation.  Innovation in the form of experimental hacking, much of which could simply fall below or outside of the FCC and other spectrum governing bodies, could become the province of literally anyone who wants to give it a go.

The article takes the reader through the evolution of SDRs and introduces a company manufacturing a product that could be to the radio spectrum and wireless communications what Apple became to personal computing.

I typically quote my favorite parts of an article, but this one is so very well-written and comprehensive, you really will want to read it in its entirety.  Click here to read, “How software-defined radio could revolutionize wireless“–and let your imagination take flight.
