Sure! You don’t need to have a software-defined radio (SDR) before you start learning how to use the technology; there are a few different paths you can take, exploring and learning about SDR.

One way to gain some experience with SDR without spending a dime is to install a free software package for the very popular, non-Linux, operating system (that starts with ‘W’), and give SDR a test drive. If you like it, you might consider getting your own hardware (like the SDRplay RSPdx, for instance), and connecting it up to your computer and running this software, too.

Why I Dived Into SDR

I have always loved radio, ever since the early 1970s, when I discovered shortwave radio. In the last couple of years, I’ve had an increasing interest in the world of SDR. When I am working, but away from home (remember those days, before Covid?), I want to sample news and programming from around the world, but through shortwave. The way to do that, I found, is by using the various SDR options which allow a person to tune a remote receiver, and listen.

I also find working with the waterfall of a typical SDR-software user interface rewarding because, instead of blindly searching for signals in a subband, I can see all of the received signals on the scrolling time representation of a slice of frequency. Simply select that signal on the waterfall, and the radio tunes right to it.

I often connect to different SDR radios around the world, to catch all manner of shortwave signals, from maritime, military air, trans-oceanic air, or coast guard radio traffic, or other interesting HF communications including amateur radio CW and SSB signals. Occasionally, I also check out VHF and UHF signals from around the world. All of that, while instead an office building that is not suited for shortwave radio reception.

I’ve now decided to give back to the community; I’ve added my SDR receiver to the collection of receivers located around the world on the SDRSpace network of SDR radios.

My new SDRplay RSPdx software-defined radio receiver is live, via http://www.sdrspace.com/Version-3, using the SDR Console software (Version 3).

The receivers are online whenever I am not transmitting and when there are no local thunderstorms.

Antenna Port A is connected to a wire antenna (a horizontal 100-foot wire that runs out from my house’s chimney to a tall tree; about 10 feet of that wire is oriented vertically, where the wire passes through a pulley and then is weighted down so it can move with wind-driven tree movement), while Antenna Port B is connected up to a VHF/UHF discone.

Both antenna systems have an AM Broadcast band notch (reject) filter reducing local AM Broadcast-Band radio station signals by about 30 to 40 dB. I need to use these because the very close KLIN transmitting tower is just miles away and those signals overwhelm the receiver. When I use the signal filters, the local AM Broadcasting signals no longer overwhelm the receiver.

In the following video, I first explain my SDR setup, and in the second half of the video, I tune around the radio spectrum, using the software to control my SDR receiver.

A Couple of Questions

After watching this video, WO9B wrote an email to me. Michael asked of me two questions, summed up as:

1. Your SDR window has the IF screen on top. How is that accomplished?

2. Your AM Broadcast filters; more info, please. I live in the area of mucho broadcast stations and that looks like something I could use.

In the following video, I demonstrate how I changed my layout of the SDR Console software. And, I mention the AM Broadcast Filter for SDR Receivers (the hardware filter is found here: https://g.nw7us.us/3kU5SJN).

To Use My Receiver

Download the latest version of SDR-Console from https://www.sdr-radio.com/download – there is a 32-bit and a 64-bit Windows installation package.

The 64-bit installation package may be downloaded from one of these three sources:

1. Google: https://g.nw7us.us/3auBq44
2. DropBox: https://g.nw7us.us/310ooIG
3. Microsoft: https://1drv.ms/u/s!AovWaZDu7Hrd3U-yqK1bs3wuaFw2?e=o4nKeh

The 32-bit installation package can be downloaded from one of these three sources:

1. Google: https://g.nw7us.us/3iLasrZ
2. DropBox: https://g.nw7us.us/3g4VcVc
3. Microsoft: https://1drv.ms/u/s!AovWaZDu7Hrd3U4mJiiRtI9lm70s?e=HDG4ZX

Install the SDR Console package according to the directions given. Once you have the software installed, you will want to add my server. It takes some work to get familiar with the software, but there are online FAQs on how to begin.

One guide on how to add a server to the list from which you can pick may be found, here:

https://www.sdrplay.com/wp-content/uploads/2018/02/SDRConsoleV3-ServerGuide1-1.pdf

I worked on getting all of the bugs worked out of my installation before making the video. It did take some work, and reading up on things. But, the software is solid and a good contender against SDRuno, and HDSDR, and, this way I can share it online with you.

My server is known as, ‘0 NW7US‘ — it will be online when I am not using my antenna systems for transmitting. It will be offline during thunderstorms, or during times when I must use the systems for transmitting.

Software-defined radio is a great way to hear all sorts of communications, from local AM broadcast stations, FM stations, VHF Air Traffic, to shortwave radio stations including amateur radio HF communications.

The hamfest held each year in the St. Louis suburb of Collinsville, IL is called Winterfest. I blogged earlier about the hamfest getting a windfall this year in adding to their growing set of Forums and other programs on contesting and so forth by welcoming the Wes Schum Symposium. Here’s how the Winterfest 2020 Chair described this past January’s events:

The St. Louis & Suburban Radio Club Winterfest has added some great events from previous years. We have added floor space to include Education Alley, doubled our forums and increased our operating hours to 4pm. In addition to these changes, Winterfest has been selected as the ARRL Midwest Conference for 2020. The weekend starts on Friday January 24th with the W9DYV Radio Symposium during the day and a DX/ARRL banquet that evening. Saturday January 25th Winterfest kicks off at 8 a.m. with the opening of the sales floor, VE testing, all day topical Forums, and Contest College starting at 1 p.m. with 10 plus hours of contesting forums and discussion hosted by top area contesters. We invite all hams to come to Winterfest for a weekend of Amateur Radio fun.

Rebecca Carroll, Winterfest 2020 Committee Chair

Kyle Krieg AA0Z, President of SLSRC, and Rebecca KC9CIJ sent me the numbers from the hamfest. They were up 20 percent from the previous year! Wow! How many local or regional hamfests can report that “windfall” in attendance? I don’t have the numbers for that but I don’t think there’d me too many but it’s unfortunate that we don’t have a national set of numbers on hamfest attendance. Hmm. ARRL, if you’re listening, I hope you find those 30,000 hamfest attendance numbers…too soon, Lol?

Nick Tusa K5FF, who chairs the Wes Schum Symposium each year, sent me a list of pre-registered attendees for that specific part of Winterfest 2020. He said that there were a considerable number of walk-up registrants so his list is an under-estimate of this year’s actual attendance. I’ve prepared a map illustrating the “draw” to the Symposium this year in Collinsville (marked with a + sign). If we ignore the extreme distant pre-registrants, it appears to represent the market potential map I created in my previous blog post about where Winterfest could draw from in the coming years. It’s unfortunate that Winterfest per se does not record the call signs of those paid attendees so we could see where their market draw looks like. Perhaps next year!

The 8th W9DYV’s Amateur Radio Symposium wrap-up with video of the presentations can be found at the Central Electronics website. They are well worth watching! They include (with embedded links to the video):

• A High Performance SDR Receiver for the Ham: Bob Nickels W9RAN
• HF Receiver Performance: Rob Sherwood NC0B
• Understanding of Human Speech Articulation: Dr. Bob Heil K9EID
• Wes Schum (W9DYV) and Central Electronics: Nick Tusa K5EF
• Drake T4XC: Low Power Output and Why: David Assaf W5XU
• AM and the story of the Gates BC-1T: Bob Allison WB1GCM
• Vintage Radio and Homebrewing Adventures: Lynn Fisk K5LYN

Windfall for Winterfest 2020? Yep. A 20 percent bump certainly suggests that. Our public relations contributing to that? Yes, but even though there were a lot of eyes seeing both the AmateurRadio.com syndication and the QRZ.com front page articles, it’s a stretch to make such claims and I do not, at all. But our discussions on what Rebecca and her team had planned as well as what Nick was doing by moving the Symposium to Collinsville, IL certainly did not hurt! The fundamentals are the hard work, ingenuity, and willingness to plan for a hamfest that hams would enjoy should they decide to attend. That’s always the case. But it can help if you wave your arms—or get others to wave theirs on your behalf—and let folks know about what you’re planning. Keep an eye out for the St. Louis & Suburban Radio Club’s website for next year. I hear they’re already at work lining up a terrific banquet speaker!

This was my first time to visit what is commonly called Dayton. Except now it’s in Xenia. And those who want to ensure that you aren’t a Real Ham if you didn’t attend Dayton wear tee shirts to that affect. So, it’s a thing. But whether you attended the “old” Hamvention or the latest edition in nearby Xenia, that’s a thing, too. And both are ok.

This year, the ICQ Podcast Team had eight of the eleven “Presenters” (British terminology) come to Hamvention and rent an AirBnB in lovely, historic Lebanon, OH. Colin M6BOY arranged for some of our listeners, including two from another podcast team, to donate toward the cost of producing nice ICQ Podcast Team Polo Shirts. They were hits in that they drew quite a bit of attention as we roved the Greene County Fair Grounds in a pack, except for Dan KN6BU who teaches his One-Day Tech Class most of the day on Saturday. The Team was very humbled by the number of listeners who approached us, several times with $20 bills extended to help with production costs. We enjoy talking about amateur radio but to get these expressions of gratitude from listeners is, well, just a humbling experience. Thank you all who took the time to stop and speak with us about the podcast.

The podcast Team is largely from the UK and a couple hold U.S. amateur licenses but must only use them (and the higher power they are allowed) on American soil. During our conference call to organize this first trip by the European group to the States, I offered to bring one of my portable HF rigs to the house we had secured in Lebanon for them to activate their U.S. call signs for the very first time. Martin M1MRB / W9ICQ and Chris M0TCH / N4CTH were able to do this. Martin worked Cuba but that station never got the last letter of his call. Chris worked a couple of stations but the need for a Snickers Bar side-tracked him. But Edmund M0MNG played Big Gun on the front porch as he worked many stations working Grey Line as the 40M band did it’s nightly thing. Dan KB6NU, of CW Geek fame, kept trying to figure out how to connect a keyer he bought in the bone yard to the transceiver. But, of course, I was not any help with my own rig as I haven’t yet gotten proficient in CW. This was a Yaesu FT-891, running 50 then 90 watts into a Wolf River Coils TIA vertical, powered by a Bioenno 20aH Life4Po battery. And Yuengling refreshments. Martin and I conversed well past our due date for sleep. Being about the same age, Martin and I have developed a close friendship during my first and now second stint working with the podcast. A good time was, indeed, had by all. And no one was harmed in the production of this event!

The Team was working quite a number of scheduled, and a few impromptu, interviews with company officials and prominent hams by day (see here), and enjoying visiting with one another by evening. Due to Colin’s midnight editing efforts, we published three time-sensitive product announcement interviews for a special episode on Sunday. But several less time-sensitive ones will come out in the next few months too. We toured WLW, the AM powerhouse of long history near Cincinnati, and the VOA Museum for the Bethany Relay Station. Unique history. And important if you’re a ham radio operator or SWL. The fact that we were doing this tour together after a joint chili dinner with the Amateur Radio Newsline team made it extra special. We thank Neil Rapp of Ham Talk Live for arranging our tour. We compared notes on our individual amateur and broadcast radio experiences while in awe over getting a special instruction on the former 500,000 watt Bethany Relay VOA transmitter. Martin M1MRB and I even got interviewed by the visiting podcast team from Pod People. That was different but most pleasant and enjoyable for us. Good thing that’s an audio-only podcast as we realized we were standing so the NSFW stickers on the back of a pickup truck would have video-bombed our head shots.

Bill N3JIX kept us entertained with his (and my) quirky humor and color-coordinated bandannas. His wit belies his deep understanding of networking radio technology as exhibited in his interview of Gerald Youngblood, President of Flex Radio Systems. Bill and I share a number of common interests outside of amateur radio, including IT which we both have a long history in as well as how libraries work. Ed DD5LP had braces to match his orange team shirt (and new red hair). Ed’s quick-on-the-draw reactions to ham radio discussions was something that I enjoyed immensely. Chris M0TCH has been to the States for work and pleasure several times. So he drove the van. And that was both a good and safe thing. Even though I’m from the States, I had driven 12 hours up and really appreciated the break from driving. Chris was already a friend through our podcast experiences but it was a real delight to spend time with him in person.

But it would be a real contest to see whose sense of humor was best. Some dry, some loud, some witty. But all great in-person QSOs from a team that meets online every two weeks to record a podcast. We missed those Team members who could not make the trip. I truly hope we can do this again whether it’s in Xenia or across the pond. If so, look for the horde of orange shirts. They don’t bite. But they do have fun when it comes to amateur radio.

Here is video footage of the journey to Antarctic Bouvet Island, made by the 3Y0Z amateur ham radio team. This footage caught a few moments on the deck of M/V Betanzos.

As you can see in the last moments of this footage, the weather conditions contributed to the decision to abort the DXpedition, as it was far too dangerous to continue this expedition.

As reported by ARRL:

“Our captain has decided that it is in the best interest of safety and expediency to proceed directly to Capetown, South Africa, rather than Punta Arenas, Chile. We are now heading north to avoid the possibility of encountering ice. Currently, there is no ice in sight or on radar. In due time, we will head easterly toward Capetown. Our entire team is safe. Most are resting in their bunks and in good spirits. We will keep the amateur radio community and our families informed, as we continue our journey.”

In a huge disappointment for the DX community and the members of the 3Y0Z Bouvet Island team, the DXpedition’s leaders announced at 2000 UTC today (February 3) that a decision had been made to abort the DXpedition and head back to Chile.

“During the last 72 hours, we continued to experience the high winds, low clouds, fog and rough seas that have prevented helicopter operations since our arrival at Bouvet,” said an announcement on the 3Y0Z Bouvet Island website. “No improvement was predicted in the weather forecast for the next 4 days. Then, last night, an issue developed in one of the ship’s engines. This morning, the captain of the vessel declared it unsafe to continue with our project and aborted the DXpedition. We are now on our long voyage back to Punta Arenas. As you might imagine, the team is deeply disappointed, but safe. There is already talk about rescheduling the DXpedition.”

Bouvet Island currently is the third most-wanted DXCC entity, behind Kosovo and North Korea. The 3Y0Z DXpedition, comprised of top operators with considerable DXpedition experience, has been in the planning stages for 2 years and had attracted contributions from clubs and individuals around the world.

A dependency of Norway, Bouvet is a subantarctic island in the South Atlantic. The last Bouvet activation was 3Y0E, during a scientific expedition over the winter of 2007-2008.
