The best radio you have is the one in front of you

This autumn, I’ve received a number of emails from new readers who’ve dusted off the radio in their closet and decided to get back into shortwave radio listening and/or ham radio.

I can’t recall another time I’ve gotten so many similar messages and I can only attribute it to the fact so many people across the globe are still having to social distance due to the C-19 pandemic.

There’s.a common theme in the messages I’ve been receiving from readers. Here’s an excerpt from the latest message (note that I removed the model name from this question because, frankly, it’s irrelevant):

“[My radio] seems to be in great working order. It’s been stored in a climate controlled environment and besides needing a little DeOxit on some of the pots, it works like new. I couldn’t be happier! My question to you is, this model is from the 1990s when I used to be hot and heavy into radio. I know technology has advanced by leaps and bounds since then, so as I get back into radio maybe I should invest in a newer model? What do you think or suggest?”

It’s true that radio technology has gone through a massive number of innovations since the 1990s. We’ve seen the advent of Software Defined Radios and portable receivers/transceivers sporting DSP technology.  Far be it from me to dissuade anyone from acquiring new gear!

With that said, I also believe that the best radio you have is the one in front of you. Period.

Listening is a skill

You can’t buy it. Whether you’re an SWL or ham radio operator, most of the time you’re on the air, you’re listening. And the best filter you have is the one in your head. I’ll quote from an article I posted many moons ago:

My good friend Vlado (N3CZ) is a case in point: he is one of the most capable ham radio DXers I know. His extraordinary ability to pull intelligible conversations and CW (Morse code) out of the static, even in crowded radio conditions, is simply astounding. Vlado’s main transceiver is nearly two decades old, and by no means a benchmark technically. If you ask Vlad if he uses filters and digital signal processing, he will wisely tell you, in his Macedonian accent: “Your best filter is between your ears.”

The same goes for SWLing. I have spent enough time listening to shortwave and weak DX that I can now pull conversations out of the noise that my (non-radio) friends can barely detect. I’m convinced this is healthy exercise for the old grey matter.

A seasoned radio enthusiast can grab any radio and make the most of it.

Imagine what Joe Walsh could do with a toy guitar…

Do you think the guitar makes him one of the greatest guitarists of all time?

 

Many of the advances in technology over the past two or three decades has, of course, given us better tools for working weak signals. But more importantly, it’s brought down the price of performance. I can invest $200 in an SDR that will perform as well as or better than multi thousand dollar benchmark receivers from the 1990s. So yes, in terms of equipment, it’s a brilliant time to be an SWL or ham radio operator.

But at the end of the day, your skills are more important your gear.

My advice?

Make the most of the radio you have.

Challenge yourself to log a certain amount of DX with your radio–try to work states, counties, provinces, regions, territories, or countries. Make your own goals!

Take your radio to the field.

Experiment with antennas.

Get to know your radio so well you can use it blindfolded!

If you still feel you want to invest more in your gear, go for it and don’t look back!

That will be all.

SDRuno V1.40.2 released

(Source: SDRplay via Mike Ladd)

SDRuno 1.40.2 has been released. This is to fix the ini file corruption issue we posted about recently, but it also introduces some new features and more plugin functionality. Release notes can be found here: https://www.sdrplay.com/docs/SDRplay_SDRuno_Release_Notes.pdf

Please note that the SDRplay plugins and community plugin installers that are included in the SDRuno installer are also available on our downloads page and will be updated when needed independently of SDRuno. If you are installing them separately, please make sure you get the right installer for the version of SDRuno you are using.

Added
• Hotkey to start/stop stream – P.
• Support for loading and saving profiles (supports multiple VRXs).
• Profile file area in the memory panel below the memory bank file area.
• Button in the memory panel to store profiles.
• Checkbox in the main panel settings to disable and hide the Bias-T function.

Changed
• LO and VFO for VRX#0 now separate on start-up and when loading a profile.
• ini file is only saved when SDRuno closes cleanly.
• Halved the size of the memory bank file are in the memory panel to accommodate the profile file area.
• Overhaul of the minimise and restore functionality (now only main panel appears in the taskbar when minimised).
• Plugin Control panel look/feel now matches the rest of the SDRuno panels.
• The default directory for community plugins is now the same as in the Community Plugins installer for ease of use.

Fixed
• Memory panel being flagged as modified when it is not.
• Check for new version can sometimes get something other than the version number.
• HDR 630m band was non-functional due to the wrong centre frequency being used.
• If decimation had been set before the 10m band was selected, the decimation value would be wrong after the band was unset.
• Cancelling wav file open window on start-up allowed SDRuno to continue to open with no input.
• SDRuno could crash on start-up if the memory bank referenced to be open was empty.
• Clicking on the frequency title in the memory panel to sort the frequency list could cause the
current band to be unframed.
• The Plugin Control panel will no longer allow the SDRuno Plugins folder to be selected when
using the right click method as community plugins should be stored elsewhere.
• Manual frequency entry after being band framed did not disable the notch filter.
• Pausing a memory scan could make it impossible to un-pause.

Known Issues
• SP2 CWAFC drift issue (Zoom/window size/freq display)
• IF output mode disabled SP1 spectrum mouse clicks

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 Jerome van der Linden, Zack Schindler, and Wilbur Forcier and  for the following tips:


Powering communication networks using solar power (BAI Communications)

BAI Communications (BAI) is committed to reducing emissions and contributing to a more sustainable future.

Over the past four years, BAI has invested in a number of initiatives that reduce power consumption as well as the carbon released into the atmosphere.

This year, four solar-powered sites were introduced in BAI’s broadcast transmission network; Yatpool, Victoria; Mawson, Western Australia; Minding, Western Australia; and Brandon, Queensland.

The annual reduction in CO2 emissions from our recent solar investment is 698 tonnes, equivalent to reducing:

  • Greenhouse gas emissions from 2.7km driven by an average passenger vehicle
  • CO2 emissions from charging 89 million smartphones
  • Greenhouse emissions from 237 tonnes of waste sent to landfill

Find out how BAI implemented this solar power initiative as part of our commitment to managing our energy use and reducing consumption.

The complexity of sending sounds to (and from) space (Mashable)

Communication with astronauts in space is vital, whether it’s during travel, when they’re doing experiments on the International Space Station, or just want to chat. It’s also pretty tricky.

That’s the topic of the latest episode of Twenty Thousand Hertz, where host Dallas Taylor speaks with International Space Station commander Peggy Whitson, NASA audio engineer Alexandria Perryman, and astrophysicist Paul Sutter to get an idea of how communication between astronauts and Earth works across the vacuum of space.[]

NSF to decommission Arecibo radio telescope (Space News)

WASHINGTON — The National Science Foundation announced Nov. 19 it will perform a “controlled decommissioning” of the giant radio telescope at the Arecibo Observatory in Puerto Rico, citing recent damage that made it unsafe to operate or even repair.

In a call with reporters, NSF officials said two broken cables used to support a 900-ton platform suspended over the telescope’s 305-meter main dish put the entire structure at risk of collapse. One cable slipped out of its socket in August, falling to the dish below and damaging it, while the second broke Nov. 6

Both cables are attached to the same tower, one of three surrounding the main dish. “The engineers have advised us that the break of one more cable will result in an uncontrolled collapse of the structure,” said Ralph Gaume, director of the NSF’s Division of Astronomical Sciences, referring to cables attached to that same tower. That would result in the platform crashing down to the main dish and potentially toppling one or more of the towers.

Engineers advising the NSF and the University of Central Florida (UCF), which operates Arecibo for the NSF, concluded that it was not possible to safely repair the structure because of the collapse risk. “After the recent failure, WSP does not recommend allowing personnel on the platform or the towers, or anywhere in their immediate physical vicinity in case of potential sudden structural failure,” stated WSP, one engineering firm involved in that analysis, in a Nov. 11 letter to UCF.

“NSF has concluded that this recent damage to the 305-meter telescope cannot be addressed without risking the lives and safety of work crews and staff, and NSF has decided to begin the process of planning for a controlled decommissioning of the 305-meter telescope,” said Sean Jones, assistant director of the NSF’s Mathematical and Physical Sciences Directorate.

Engineers are working on a plan to carry out that controlled decommissioning, which will take several weeks to complete.[]

International Broadcast Station Interference Overwhelms Hurricane Watch Net (ARRL News)

As Category 4 Hurricane Iota neared landfall in Central America on November 16, the Hurricane Watch Net (HWN) was forced to suspend operations at 0300 UTC because of what HWN Manager Bobby Graves, KB5HAV, described as “deafening interference from a foreign AM broadcast station that came out of nowhere at 0200 UTC.” At the time, the net had shifted to its 40-meter frequency of 7.268 kHz, collecting real-time weather and damage reports via amateur radio.

“This was heartbreaking for our team, as the eyewall of Iota was just barely offshore,” Graves said. “The storm had weakened slightly to a Category 4 hurricane with sustained winds of 155 MPH.” After activating at 1300 UTC, the net was able to collect and forward reports from various parts of Nicaragua and Honduras via WX4NHC throughout the day for relay to forecasters at the National Hurricane Center in Miami. Iota was the most powerful storm on record to make landfall this late in the hurricane season.

Graves said the very strong AM signal was on 7.265 MHz. “From my location, it was S-9,” he told ARRL. “You could not hear anything but the BC station.” The source of the signal was not clear, but as he noted, other foreign broadcast stations are to be heard from 7.265 to 7.300 MHz and splattering close by.

Stations handling emergency traffic during the response to Category 5 Hurricane Iota had requested clear frequencies on November 16 to avoid interfering with the HWN and with WX4NHC, as well as with a Honduran emergency net operation on 7.180 MHz and a Nicaraguan emergency net operating on 7.098 MHz. It’s not known if those nets were also affected by interference from the numerous broadcasters on 40 meters. “Thank you to all who allowed us a clear frequency,” Graves said on behalf of the HWN.[]

[Personal note: I understand that this is very late in the season for the Hurricane Watch Net to activate. Normally, they operate on 20 meters, but moved to 40 meters for the evening. I don’t believe net control was aware that this portion of the 40 meter band is shared with international broadcasters. I don’t believe the international broadcaster could be called “interference”–they operate on a publicly available schedule–ham radio nets are actually the ones who are frequency agile. This seems to have just caught them off guard. I believe the HWN will be using frequencies below 7.2 MHz moving forward.]

Video: A virtual tour of the Aihkiniemi DXing base in Lapland, northern Finland

Many thanks to SWLing Post Contributor, Christoph Ratzer, who recently shared the following video tour by Mika Mäkeläinen. Mika desxribes this video on YouTube:

Join me on a virtual tour of the Aihkiniemi DXing base in Lapland, in northern Finland. This is a nonscripted five-cent tour looking at what the Aihkiniemi cabin can offer for visiting AM DXers. The video was shot in November 2020 during DXpedition AIH124 – meaning that during the first decade of its existence, Aihkiniemi has already hosted 124 successful expeditions. The antennas (a total of 14 Beverage-type wire antennas) are permanent, but participants bring their own receivers and laptops. There’s one essential activity missing from this video though: checking the antennas, which is a major job. Every DXer is expected to check – and if necessary, clean and repair – all the antennas, which run in the forests around the cabin. So there might be a part 2 in the future.

Wow! This little DXing cabin is on my bucket list. I will, someday, make my way to north Finland and spend time DXing from this unique reception spot. The quality of the equipment and antennas is truly amazing.

Thanks for the tip, Christoph!

April’s collection of Japanese language WebSDR recordings for October 2020

Many thanks to SWLing Post contributor, April TimeLady, who writes:

In this email is a link to recordings I made from Japanese SDRs over the course of October 2020 and have uploaded to archive.org. This is the link:

https://archive.org/details/JPSDROCT2020

The original files are in .wav, archive.org converts them to mp3 and flac. Files with sas in them are supposed to be in stereo. There are many shortwave recordings in it, as well as mediumwave.

For anyone who is hunting IDs, Japanese radio stations definitely announce their full ID at 5 AM Japan Standard Time each day. On the top of the hour commercial radio stations ID. On Mondays between 1 and 2 AM (commonly given as between 25:00 and 26:00 Sundays on Japanese radio schedules) many Japanese radio stations go off the air for transmitter maintenance and give a very full, 5 minute long ID. I believe I have included one that I clipped for 1008 AM in Osaka in this month’s collection; 1008 AM, JONR is definitely in full AM stereo.

A good reference for Japanese AM radio call signs is on MWList at http://www.mwlist.org/mwlist_quick_and_easy.php?area=2

Thank you for reading this, and please take care.

Thank you, April for uploading and sharing your recordings! I’ve enjoyed browsing these each month!
