China Radio International: Jim seeks help understanding language schedule and transmitter locations

Many thanks to SWLing Post contributor, Jim Meirose, who asks:

Each day in NJ I am hearing China Radio International in German on 9.570 MHz. It “fades in” up out of the noise about 2 pm EDT, and strengthens until the broadcast signs off just before 3 pm (1800 UTC).

Two things: first, I have found on a couple of websites that a broadcast from CRI on 9.570 does run daily and signs off just before 1800 UCT, but–the listings say it is in English. What I am hearing is in German.

I would like to find someone who can explain the discrepancy in languages between the listings and what I hear.

Second, I would like to know for sure where the transmitter for this broadcast is located. I know CRI broadcasts not only from Beijing but from Albania, Cuba, and possibly others. Can someone tell me the answer?

Thanks very much.

Per your request, Jim, I’ll toss your question out here to the experts in the SWLing Post community. Please comment if you can help Jim with his inquiry!

Upping my CW pile-up game with Morse Runner

I mentioned in a previous post that I’ve been practicing my CW (Morse Code) skills in an effort to build confidence to do a Parks On The Air (POTA) CW activation.

But how in the world do you practice handling a CW pile-up without actually going on the air–?

I’m glad you asked!

My DXing and contest friends have often touted an amazing free PC application developed by Alex Shovkoplyas (VE3NEA) called Morse Runner.

Morse Runner’s goal is simple: teach you how to manage a CW pile-up.

In short? It’s incredibly effective!

When you start a Morse Runner session, the application emulates the sound and atmosphere of the HF bands in CW mode (meaning, a narrower filter setting). It’s very convincing.

Instead of using a key to send a CQ, the Morse Runner interface emulates a contest logging system where a computer generates your CQ and sends the signal report you record for a station.

Screenshot of Morse Runner (click to enlarge)

You simply set a few parameters like your call sign, max CW speed, pitch, and bandwidth, then press the “run” button and call CQ by pressing the F1 key on your keyboard.

Within a few CQ calls, you’ll hear anywhere from one to several stations answer your CQ (depending on your settings). Your job is to then start logging those stations accurately from the pile-up. If you reply with an incorrect call, the other station will repeat their call until you correct it.

Morse runner has band condition settings you can select like: QRN, QRM, Flutter, QSB and–yes–even LIDs.

Quite often I’ll accurately reply to a weak station and they’ll send “AGN?” and I repeat their report until they copy it.

Morse Runner is so convincing that when I’m in the middle of a big pile-up, I honestly forget I’m communicating with a computer application! I get some of the same excitement and the–let’s be frank–anxiety I would get on the air during a live CW pile-up.

If you select the “LIDs” Band Conditions setting, it’ll crack you up with how accurately it portrays annoying operators who either deliberately or unintentionally try to interfere!

Here’s sample audio from a session this morning:

The screen shot above shows the settings I used for this very tame session with no large pile-ups. If you’re a seasoned CW contester, pump up the speed and the activity level then you’ll feel like you’re on the Heard Island DXpedition!

In short: Morse Runner is giving me the courage to do my first CW park activation. I highly recommend it!

Video: When “Tomorrow’s World” demonstrated digital radio

Many thanks to SWLing Post contributor, Jason W, who writes:

You might be interested in this episode of the BBC series tomorrow’s world from 17th Feb 1993 on YouTube:

10:23 to 14:50 has a introduction and demonstration of digital radio in the UK and concluding with “the experts say we will be fully digital by 2020 it’s a long wait” (referring to the switch from fm to digital radio in the UK which is yet to happen).

I thought it might be interesting to highlight this on the blog in 2020.

We can forgive the bit where she suggests digital radio will operate alongside analogue FM in the same frequency band. This Wikipedia on the history of digital broadcasting in the UK shows the UK adopted the DAB Eureka 147 standard in a SFN (single frequency network) from the start of test transmissions in 1990.
https://en.m.wikipedia.org/wiki/Digital_radio_in_the_United_Kingdom

The same episode has a later piece on wide-screen digital television. (20:18 to 23:41) ending with the line “like digital radio, it is a few years away” 🙂

This is fantastic! I love watching vintage Tomorrow’s World episodes. It’s great to see how well they predicted the future and what they considered to be meaningful future innovations at the time. Thank you for sharing, Jason!

Photos of the lab599 Discovery TX-500 in the field

Many thanks to SWLing Post contributor, Don (W7SSB), who shares the following photos of the new lab599 Discovery TX-500. Don notes that all of these photos were taken in Russia–where the TX-500 is manufactured–and include a number of Chameleon resonant field antennas.

Thanks for sharing these, Don.  The thin form-factor of the TX-500, paired with a resonant antenna, certainly makes for a lightweight portable field setup!

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Michael Bird,  John Figliozzi, and Jack Dully for the following tips:


Radio Six Pops Up Again on Shortwave (Radio World)

Radio Six International has not been a full-time shortwave broadcaster for some time. But after two recent live broadcasts on 6070 kHz prompted by the pandemic, it says it will continue monthly broadcasts at least for now.

WLW’s America’s Truckin’ Network To Refrain From Political Talk (Radio Insight)

iHeartMedia News/Talk 700 WLW Cincinnati has eliminated political talk from its overnight “America’s Truckin’ Network” show hosted by Steve Sommers.

The Cincinnati Enquirer reports that Sommers told listeners of the change on Monday morning’s show after multiple unspecified complaints.

In the on-air statement, Sommers blamed the change on a group of individuals who took offense with comments made by a caller a few weeks ago.[]

NPR Radio Ratings Collapse As Pandemic Ends Listeners’ Commutes (NPR)

Broadcast ratings for nearly all of NPR’s radio shows took a steep dive in major markets this spring, as the coronavirus pandemic kept many Americans from commuting to work and school. The network’s shows lost roughly a quarter of their audience between the second quarter of 2019 and the same months in 2020.

People who listened to NPR shows on the radio at home before the pandemic by and large still do. But many of those who listened on their commute have not rejoined from home. And that threatens to alter the terrain for NPR for years to come, said Lori Kaplan, the network’s senior director of audience insights.

“We anticipated these changes,” Kaplan said. “This kind of change was going to take place over the next decade. But the pandemic has shown us what our future is now.”

Commercial radio is experiencing, if anything, worse declines. But audience research commissioned by Kaplan indicates that NPR’s audience is disproportionately made up of professionals who are able to work from home and who are interested in doing so even after the pandemic subsides.[]

The Day That New York Had Two Noons, a Century After Losing 11 Days (Untapped New York)

New York’s history has included everything from transit strikes to riots over Shakespeare to immigration from nearly every country in the world. Yet, for much of this history, people didn’t always know the “correct” time or date. Until 1883, virtually every place in the country set local time according to the sun. According to Sam Roberts in his book Grand Central: How a Train Station Transformed America, “Typically, noon would be regularly signaled so people could synchronize their clocks and watches.” From dropping a ball down a flagpole in Manhattan to ringing a gong, settlements all across the country would alert people of noon. But as railroads spread throughout the country, it was nearly impossible to standardize the time.

“A passenger traveling from Portland, Maine, to Buffalo could arrive in Buffalo at 12:15 according to his own watch set by Portland time,” Roberts writes. “He might be met by a friend at the station whose watch indicated 11:40 Buffalo time. The Central clock said noon. The Lake Shore clock said it was only 11:25. At Pennsylvania Station in Jersey City, New Jersey, one clock displayed Philadelphia time and another New York time. When it was 12:12 in New York, it was 12:24 in Boston, 12:07 in Philadelphia, and 11:17 in Chicago.”[]

Video: Josh takes us on a tour of the lab599 Discovery TX-500 QRP transceiver

Many thanks to SWLing Post contributor, Josh (KI6NAZ), who shares a link to his YouTube channel where he takes us on a tour of the lab599 TX-500 Discovery:

Thanks for sharing this, Josh! The TX-500 is certainly a unicorn in the world of field-portable QRP radios since it’s designed to be weather-proof.

lab599 has confirmed that they will dispatch a TX-500 loaner unit for my upcoming review.  I’m looking forward to see how it plays in the field and might compare with other QRP rigs in my arsenal!
