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 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!

Richard shares recordings of The Buzzer

Many thanks to SWLing Post contributor, Richard Lacroix,

I was intrigued by your post, “The ghostly radio station that no one claims to run (BBC Future)”. I attempted to listening to the station on 4625 kHz from my home location here in Toronto, Ontario Canada but unfortunately could not receive the signal. WebSDR to the rescue. I managed to locate a couple of KiwiSDRs in Russia which yielded great reception of “The Buzzer”.

I figured that some readers may be interested in knowing what the buzzer sounds like. I have therefore included 2 recordings of the broadcast; the first in AM and the second in USB mode with a 3.2 kHz wide filter setting. I am also sharing a screen shot of the waterfall which clearly depicts the signal [see at top of post].

Recordings

The Buzzer recorded July 18, 2020 at 01:07 UTC  on 4625 kHz in AM mode:

The Buzzer recorded July 18, 2020 at 08:26 UTC  on 4625 kHz in upper sideband mode:

Thank you for sharing this, Richard!

Like you, I have difficult receiving The Buzzer from North America (especially in summer conditions with QRN). That’s where KiwiSDRs really come to the rescue. Thanks again for sharing your recordings.

How would an Icom IC-705 compare with the Xiegu G90?

Xiegu G90 with remote head detached.

Many thanks to SWLing Post contributor, Paul, who asks:

How does the Icom compare with the Xiegu G90, besides lack of a built-in antenna tuner, and having lower transmit power, and a better screen?

Good question, Paul.

The G90 is a great radio for sure and has better specs and features than I would expect from a $450 transceiver. I’ve taken it on a number of portable field operations and love it. My full review of the G90 will appear in the August 2020 issue of The Spectrum Monitor.

Keep in mind that at time of posting (July 21, 2020) no one has really reviewed and compared the performance of a production run IC-705 with any other radio as of yet. I will purchase an IC-705 for review as soon as they start shipping in the US, but I don’t expect to be able to do that until September or October at best. So we can’t really speak about performance at this point.

What makes the IC-705 unique in the portable radio market is the number of features it will sport.

Here’s a short list of features the Icom IC-705 has that the Xiegu G90 does not have:

  • Attachable battery pack
  • Lower current drain in receive per Icom specifications
  • CW memory keyer with beacon mode
  • Voice memory keyer with beacon mode
  • D-Star mode with built-in WiFi to connect to Internet/hotspot
  • Built-in GPS
  • Built-in TX/RX recording
  • Broader receive range: 0.030–199.999 and 400.000–470.000 MHz
  • Multi-mode 6M/2M/70CM TX and RX
  • Touch screen display that is customizable
  • Built-in WiFi and Bluetooth
  • Native to digital modes–no external sound card interface needed
  • Frequency stability less than 0.5 +/- ppm in VHF/UHF, making it ideal to drive an amplifier for demanding tasks like EME

The Xiegu G90 actually has a few features that the Icom IC-705 will not:

  • Built-in (very effective) automatic antenna tuner
  • Antenna analyzer function [Update: Geoff notes “The Icom IC 705 does also have a VSWR Plot/analyser in the menu same as the IC7300 and iC 7100, page 9.3 in the advanced IC 705 manual”
  • 20 watts of output power (the IC-705 has a max output power of 10 watts using an external 13.8V battery source)
  • 10.8 kHz AM bandwidth (the IC-705 maxes out at 6 kHz per specs)
  • Detachable faceplate which will likely make mounting it mobile even a little easier than the IC-705 (although in truth both transceivers are very compact and should be easy to mount)
  • Side panels that protect the front faceplate and rear connections

At the end of the day, though, the Xiegu G90 is an excellent little budget transceiver. It’s feature-rich compared with other transceivers in this price bracket, but basic compared with the IC-705 or Elecraft KX3 or KX2.

The Icom IC-705 will have a retail cost well over two times that of the G90 but will sport features that no other QRP transceiver has up to this point. In fact, the list of features above is only a sampling.

If none of the unique features of the IC-705 appeal or apply to you and your operating style, save a little money and grab the G90. Or consider spending a bit more for an Elecraft KX2.

If you want an incredibly feature-rich transceiver and are comfortable with a price point in excess of $1100-1200 US (estimated at time of posting), you might delay purchasing until you’ve read a few user reviews of the yet-to-be-released Icom IC-705.

Thanks for your question!
