Canada C3 Voyage Carrying WSPR Concludes; Beacon May Remain Active on Return Trip

The epic WSPR-carrying Canada C3 voyage of the Polar Prince to commemorate Canada’s 150th Anniversary of Confederation celebration ended successfully on October 28. Over the course of the 150-day expedition from Toronto, Ontario, to Victoria, British Columbia via the Northwest Passage, the CG3EXP WSPR HF beacon was received on every continent except Antarctica, CG3EXP trustee Barrie Crampton, V…

Foundations of Amateur Radio #126 – Hearing very weak signals

This week I’m going to talk about a Digital Mode you can use with any Amateur License, or even without an Amateur License. You can set-up your radio, hook it to a computer and the Internet and after installing some software, you can join the Weak Signal Propagation Reporters.
So how do you start, what does it do and how can it help you?
First of all, WSPR, pronounced Whisper, is a way of encoding information and transmitting it across the spectrum. At the other end a radio receives that signal, sends it to a computer where a piece of software attempts to decode and then log it.
This Digital Mode, invented by Joe K1JT, is one of several modes that are gaining popularity across the Amateur Radio community because the beauty of this mode is that it’s so unobtrusive that you’re unlikely to actually hear it if you were to tune to a dedicated WSPR frequency.
If you want to find out what your station can hear, you can set yourself up as a dedicated receive-only station and report your findings to a central database where others can share your information and learn what propagation is like at that particular point in time.
Of course, it also means that you can use the same information to learn what propagation looks like in your neck of the woods with your radio and your antenna set-up.
There’s even an option that allows you to have your radio automatically change frequency – known as band hopping – and listen for WSPR signals across the bands that you allocate.
If you like, you can go to the wsprnet.org website right now and do a search for my callsign, VK6FLAB and see what stations I’ve heard since I turned it on. Go on, have a look, I won’t mind.
My station is set-up to do band hopping across all HF frequencies all day and night and during the grey-line it only listens to 80m, 40m, 15m and 10m, since those are the frequencies my license allows me to transmit on and I’m particularly interested how they work at sun-rise and sun-set.
You might have heard me before talking about how the noise at my home is atrocious. Nothing has changed, it’s still abysmal, but WSPR signals are coming in and being decoded.
If you want to do this, you’ll need a radio – any radio will work, a computer with a microphone socket and a way to pipe the audio from the radio into the computer, I’m using a 3.5mm male plug to 3.5mm male plug – you don’t need a fancy audio interface, you’re only listening. If you can connect an interface cable, your computer can also change frequency for you, but that’s not needed to get started.
Make sure that you turn the volume right down before you plug anything in. Connecting a headphone output directly into a microphone input can blow up the port if you’re not careful and WSPR doesn’t need much in the way of volume. The software helps you get it set right, so read the manual before you start.
Once you’ve set-up your radio and your computer, you can watch the signals coming in on a waterfall display, a graphical representation of the audio and frequency that shows strong signals in red and no signal as blue. You’ll find that turning up the volume too high will actually reduce the ability to hear signals.
I’m keen to learn what I can hear and how many stations my simple 10m vertical antenna can hear across the Amateur Radio spectrum.
I’d love to hear your weak signal stories and see what you can hear. As I said, it seems I’m becoming a short-wave listener after-all.

New Digital Modes Changing Complexion of Bands and Perhaps of Ham Radio

The wave of software-based digital modes over the past several years has altered the atmosphere of the HF bands. Some suggest the popularity of modes that make it possible to contact stations neither operator can even hear has resulted in fewer CW and SSB signals on bands like 6 meters and 160 meters. Traditional modes require far more interaction and effort on the part of the operator; the new…

New video Series – FLDIGI to the Yaesu FT-817

This is a series i’ve recently started to answer questions i’m often asked about both setting up the QRP stations for maximum performance (or minimum loss) as well as the configuration for FLDIGI. Its sort of an evolving thing right now, so Ill post as I have new material. Ill point out that I am ahead of this, already at setting antenna length for zero reactance, but its still in editing. Ill be posting here as content comes out

Goodbye FT8, Hello Olivia, The MAGIC Digital Mode For HF!

Previously, I made a couple videos introducing FT8 mode, and most recently how crammed packed it is on the bands with FT8 signals. Well, guys and gals, there are many other options if you are not aware (or maybe you are).

Ft8 is referred to as “the zombie mode”, not by me, but most all the people viewing this on the ZED. Sure, it gets you a distant contact, but there is no real “interaction” with the hams on both sides. The computer is doing it all for you..
Picture the efficiency similar…

Breaking News: First ZS EME Record on 10 GHz (3 cm) 

On 22 October 2017 at 15:46 UTC, Alex Artieda, ZS6EME, recorded the first-ever Digital EME QSO with HB9Q on 10 GHz. This is the first Microwave EME QSO on such a high band from South Africa and operating the new digital mode QRA64D, while using only 50 Watts at the feed of his 1,5 metre dish. Later on 23 October Alex completed 10 more EME QSOs on 10 GHz.

Last but not least on 24 October, he was able to make the first-ever Digital EME QSO in 5,7 GHz (6 cm) in the RSA with PA3DZL at 11.56 UTC, and on the same day he completed 7 more QSOs on 5,7 GHz.

Hearty congratulations to Alex for his fantastic achievements and putting South Africa back on the world Microwave map.
