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!


Winter SWL Fest: March 4-5, 2022, Online using the Zoom webinar platform

The Winter SWL Fest is a conference of radio hobbyists of all stripes, from DC to daylight. Historically, every year scores of hobbyists have descended on the Philadelphia, Pennsylvania suburbs for a weekend of camaraderie. The Fest is sponsored by NASWA, the North American Shortwave Association, but it covers much more than just shortwave; mediumwave (AM), scanning, satellite TV, and pirate broadcasting are among the other topics that the Fest covers. Whether you’ve been to every Fest (all 34, starting with the first year at the fabled Pink & Purple Room of the Fiesta Motor Inn) or this year’s will be your first, you’re sure to find a welcome from your fellow hobbyists, even if it’s a “virtual” welcome!.

In 2022, the 35th Annual (!!) Winter SWL Fest will again be going virtual courtesy of the Covid-19 pandemic.  All activities will be conducted online via the Zoom webinar platform.

Registration will be $10 per computer screen to defray the Zoom hosting expenses.  If you already have a PayPal ID you can simply send $10 from your account to swlfest [at] naswa.net.  If you aren’t a PayPal member you may also register online via PayPal here.  Paper registrations will not be processed for 2022.

Your hosts, Richard Cuff and John Figliozzi, work throughout the year to ensure that attendees have a great time over the weekend, and by all accounts, they succeed stunningly. How else could this event have lasted for 35 years (egad) — even with a Pandemic — and draw people from around the world to southeastern Pennsylvania? Won’t you join us?

SDRplay Updates on Hardware Shortages (RTL-SDR Blog)

As we all know many electronic components are currently in shortage, and this global shortage is affecting some SDR manufacturers like SDRplay. Recently on their blog SDRplay have provided some updates on their hardware shortage situation. They write:

As we have mentioned before,  due to the worldwide shortage of electronic components, we are suffering from production delays at both our manufacturing subcontractor operations here in the UK.  This means that many of our resellers have completely run out of RSP1A and RSPdx devices.

However we are pleased to say that this week, we have  been able to build some additional units.  This means that by the end of next week (February 25th), our resellers should have more stocks of RSP1A and RSPdx.   More RSPduos are promised for mid to late March.

It is highly likely that even after the latest production runs are delivered, some of our resellers will run out again in the weeks ahead.  Meanwhile we are working to do all we can to secure more critical components for our manufacturers. This includes tweaks to the designs so that they can accommodate alternative more readily available parts.

Many thanks to customers who have been left waiting to buy, and to our resellers for your patience as we navigate though this situation.

Check out the new scheduler functionality in SDRuno V1.41

Many thanks to Jon Hudson with SDRplay who shares the following information about the latest release of SDRuno on the SDRplay blog:

Try out the new features in SDRuno V1.41 released today

SDRuno V1.41 was fully released today.  It includes the much requested full scheduler facility which allows you to set up numerous recording events for your RSP.  As well as providing all the expected calendar options (time of day, date, start and stop times, repeating options and so on), you can also set the ‘profile’ for each recording – this allows you to pre-set frequencies, bandwidths, demodulator options (AM/FM/USB/LSB etc.), choice of filters and antenna port selection.  Additionally you can choose the settings for connectivity to other third party software or the running of a specific plugin.

Added
• New Scheduler panel which replaces the old “Recorder” panel (launch using the SCHEDULER button in the main panel).
• A new autolayout to include the scheduler (for screen resolutions of 1920×1080 and above).
• Backup and Restore of the ini file settings (access via the main panel OPT menu)
• Screenshot button has been added to the SP1 title bar
• IQ wav files can now be used in plugins
Changed
• Autolayouts now take account of the taskbar location and size.
• Autolayouts have been improved to take account of higher resolutions.
• Saved workspace notification moved to the status bar.
• Memory Panel will now prompt to save any changes made when switching to another memory
bank.
Fixed
• Decimation and the LOLOCK state are now correctly saved and recalled within a profile.
• Main panel version tooltip now displays correct information.
• The step size could be set incorrectly when using non-FM modes and pressing any of the FM sub
mode buttons.
• ADS-B/DAB mode now handles when in both band-framed mode and also when the LO is locked.
• Bugs associated with wav file playback
• When loading a profile, the last used memory bank field will update correctly
• Saving a profile will now update the displayed loaded profile field correctly
Known Issues
• SP2 CWAFC drift issue (Zoom/window size/freq display)
• IF output mode disabled SP1 spectrum mouse clicks
• Occasionally if SDRuno is closed whilst a plugin is still running, it may not close properly. This may
necessitate a PC reboot to fix it.

You can find this latest version of SDRuno on our downloads system :https://www.sdrplay.com/downloads

Mike compares four active mag loop antennas

Many thanks to Jon Hudson who shared the following on the SDRplay Facebook page:

In this new video, Mike Harwood compares 4 different active mag loop antenna at various frequencies up to 52MHz using two SDRplay RSPduos which allowed simultaneous spectrum snapshots of the 4 loops in action with real signals.

These are loops from Bonito, Cross Country Wireless, LZ1AQ and Wellbrook.

This is the second of Mike’s antenna comparison videos. He welcomes comments which will help shape the content for future antenna experiments:

Mike Harwood explores active magnetic loop antennas with SDRplay

Many thanks to Jon Hudson with SDRplay who shares the following announcement:


Introducing a new series of videos comparing the performance of wideband active loop amplifier/antennas for HF frequencies and below. In this introductory video, Mike Harwood shows how an RSPduo enables a real-time comparison of two antennas – in this demo, he uses a Wellbrook 1530AN and one of his own compact loop creations. You can see that he has lined up several other active loop antennas/amplifiers to try in future videos, including the Bonito Megaloop FX, the LZ1AQ amp and the Cross Country Wireless amp.

SDPlay will endorse antennas which work well and formally recommend them on its website antenna suggestions page: https://www.sdrplay.com/antennasuggestions/

This is one of many videos from SDRplay – makers of the RSP family of SDR radios. See the full list of SDRplay videos and applications documents on: https://www.sdrplay.com/apps-catalogue/

The RSP family of SDRs from SDRplay cover 1kHz to 2 GHz with no gaps and give up to 10MHz spectrum visibility.

SDRplay is a UK company. The RSP SDR receivers are made in the UK and can be purchased for worldwide delivery directly from http://www.sdrplay.com/ (click on purchase and select your country to view shipping costs) or you can buy from any of our worldwide resellers listed here: http://www.sdrplay.com/distributors/ Many of the resellers offer local free shipping and/or local language technical support.

SDRplay’s article regarding counterfeit products and how to avoid them

A fake SDRplay RSP1A on Walmart.com

SDRplay recently posted this article which focuses on counterfeit products. It’s a worthy read.

They’ve seen an uptick of people contacting them believing they’ve purchased a genuine SDRplay SDR only to discover it’s a counterfeit and will not work with new SDR Uno releases.

As I’ve mentioned before: I’m not a fan of counterfeits and will not knowingly link to them on this site.

The problem with fake products is that they’re not supported by the original manufacturer and often don’t perform up to the same specifications. The price difference is negligible–sometimes fakes are even higher than the genuine article (see the ad at the top of the page as a case in point). I feel like any money saved is a moot point when counterfeit product can’t take advantage of firmware upgrades and RF performance isn’t tested and verified.

It’s best to purchase either directly from the manufacturer or their authorized dealers.

Also, when you purchase the genuine item, you’re supporting the innovators in our radio world. Companies like SDRplay, AirSpy, and ELAD–original SDR manufacturers–are always seeking a means to get the best performance and functionality out of their products. They do meaningful research and development and implement customer feedback in each product iteration.  Fake products do not: they merely copy and sell. They have no R&D department. Their quality control is all over the place.

When purchasing a new SDR–or any product for that matter–I encourage you to buy the real deal, Not only will you have product support in the long run, but you’ll also be investing in the innovators of our radio world.
