WSPR plot on a map of the world, main contacts in EU, USA and Australia
In anticipation of moving back to the main QTH in a couple of weeks, I have put up a non resonant long wire. 36.270 metres of wire, inverted V over an Oak tree. Ran WSPR over the weekend, 1 watt. (I didn't bother to test or tune the antenna!) #WSPR #hamradio

“…pico balloonists take advantage of an amateur-radio network called #WSPR (Weak Signal Propagation Reporter), a protocol developed by a rather famous #hamradio enthusiast”
Mix 61 ferrite rod is 4”x0.33”, has approx 60 turns 23AWG primary, & 2 turns 28AWG pickup coil. #NanoVNA gave me a mere 17dB dip on the target frequency. Antenna is taped to East-facing window, about 6’ above grade.
But TONIGHT’s test will be this 8”x0.33” rod. All else is the same, except with 2 rods glued together, reinforced with heat shrink, there’s more “aperture” to take in RF. Got a better match with this longer rod also… got NanoVNA to show my dip at -38dB. So I’m very hopeful about this next test.
Last night’s ferrite #MagLoop antenna test was a success, but barely. Got #WSPR decodes of only 1 station, <700km.
MUCH more detail in the ALT text.
Close up photo of 4” ferrite (mix 61) rod, wrapped slightly loosely about 57 turns with 23AWG magnet wire. The pickup is 2 turns of 18AWG, & is halfway between the bottom end of the primary coil (oriented vertically), and the bottom end of the rod.
Photo not as close, so you can see the ferrite is scotch-taped to the window about 6’ off the floor/ground. The leads of the primary coil come off the right side of the rod, then extend about 3 feet to the desktop, then attach to the variable air capacitor. These leads run parallel to each other, kept about 3 inches apart by also being taped to the window.
Next ferrite rod loop RX #antenna test setup for #160meters has the ferrite rod taped to the window so that half the world isn’t blocked by the metal-cased ham gear on the workbench. Eager to see how #WSPR does overnight.
Hola! mi nombe es Sergio y este es mi primer post en esta desconocida para mi red social espero poder compartir sobre la temática de la radioafición #hamradio #radioaficion #radioaficionado #cwmorse #youareinthelog #ft8 #antenna #rig #sdr #wspr #radioclub #ARRL
I’ve built this antenna several times, the past 2 times successfully. There are 2 differences from the previous to this one. This uses 18AWG, where the other was 34AWG. And because the bigger wire makes a bigger coil, I had to glue 2 rods together. It may be that a more interesting A/B test will be comparing the 2 ferrite rod antennas, to see how much better this one is.
Tonight’s (already running) A/B #HamRadio #antenna test is #160m #WSPR (RX only) between 6-80 #DXCommander vertical & this ferrite rod magnetic loop, indoors, on my bench.
WSPR Transmission report.
It's hard to hit the West Coast from Europe.
I need a BFA-3000. #hamradio #wspr #wsjtx
In Carmel for #WSPR and missing #neotwitter (but not enough to get back on Twitter). Here’s to hoping #neosky posts about it here!

Have you ever considered one of the capacitive hats for your #ma12, #jpc12 or similar whip based antenna? I've done some tests with and without using #WSPR: www.youtube.com/watch?v=zayH... #hamradio #portableradio

The most distant reception of my #hamradio #WSPR signal I've noticed: transmitted from Oakland CA USA, it was heard 2025-10-26T01:22Z near Windhoek, Namibia, 15,815km away. (Receptions by station DP0GVN in Antarctica, 14,811km away, are more common.)
Picture of my wspr transmitter. It consists of 5 boards. The bottom board is the microcontroller. The second board has the Si5351 oscillator. The third board is an apropriate Low Pass Filter (LPF), the antenna hangs off of that board. The top board allows the GPS module to connect. It's kind of messy as I was trying various ways to power it. Right now I just have a temporary power solution.
Picture from wsprnet.org showing recpeiton in upstate New York, Long Island, Utah, San Francisco, and around Los Angeles from my station just west of Houston, Texas.
My Arduino based 10m #wspr transmitter actually works. I thought it didn't, I was just being impatient all this time! [1/2]
For offline mapping I'm using Hamclock and Grid Tracker.

I left my radio txing running overnight on #WSPR and geeked-out this morning seeing it had been heard with only ten watts in Antarctica! DPØGVN is a club station located at the German Antarctic Research Station "Neumayer III" in Dronning Maud Land. www.qrz.com/db/DP0GVN

The following is information and screenshots of the setup that got my #DigiRig Mobile, cables for #Icom, and #MacBook Air M2 (#OS26) working #WSJTX for #FT8 and #WSPR on an IC-718.

I am house and cat sitting for friend for a few days. Chucked a bit of wire over a tree and had a play with #WSPR. #hamradio #cats #QRP

Trying to track some ham radio carrying balloons. Picked up a signal from one over Greenland this time.
I am absolutely amazed at #WSPR. This is on 10 watts from a vertical in a valley on the east coast of Australia during daylight hours. #hamradio #amateurradio blows me away. #vk
Been playing with 160m WSPR rx over the couple of weeks generally hearing VK so really pleased to hear E51WL this evening.
Using a funcube dongle SDR and the wsjtx software on a Linux machine. The antenna is a 4m high 22m long wire with radials and a 4 to 1 balun.

Ein Poster, das einen Vortrag über den Weak Signal Propagation Reporter (WSPR) ankündigt. Das Poster hat einen dunklen Hintergrund mit einer Weltkarte, die von Linien durchkreuzt wird, die ein Funknetzwerk darstellen. Oben steht in großen, goldenen Buchstaben "75 JAHRE DARC" und "75 JAHRE LEIDENSCHAFT FÜR FUNK". Der Vortrag findet am 30. August 2025 von 11:00 bis 11:45 Uhr in der Stadthalle Baunatal, Raum Alpha (Raum 119) statt. Der Referent ist Reinhard Nießner DK3TG. Eine kleine Grafik rechts zeigt eine Oszilloskop-Ansicht mit Signalwellen und eine Hand, die ein Messgerät bedient.
Vortrag zu WSPR: Erfahre von Reinhard Nießner (DK3TG), wie du Antennen in Echtzeit vergleichst und deine Station 24/7 überwachst.
