WSPR chatter

Last edited: 10.7.2018

Inspired by fellow ham, WSPR enthusiast and blogger PE4BAS, I've decided to compile my own personal WSPR DXCC list also, i.e. a list of DXCC countries where my 200 mW WSPR signals were spotted. I started WSPRing (on and off, not continuously) with my QRP Labs U3S in the late winter of 2017, and so far have reached a total of 63 countries with it. My WSPR DXCC list can be found here, and can be accessed at all times from the "Pages" section in the bar to the right.

For each month I download the complete WSPR database CSV file from wsprnet.org and import it in Excel to analyze my WSPR spots. The CSV files are too large to be used directly in Excel though, so I first break them up with the use of a little program called CSV Splitter from Polderij IT which can be downloaded for free. If you need some help with this I'll be glad to help out.

So what else is out there on the WSPR front and HOT to report on?

Well, the Canada C3 icebreaker expedition ship Polar Prince after a succesful circumnavigation of North America has returned in its home port of Lunenburg in Nova Scotia on Canada's east coast. During the voyage from Canada's east to west coast via the Arctic, the ship could be tracked by its onboard HF WSPR beacon with the callsign CG3EXP. Later on, after the C3 expedition had successfully ended, the ship's WSPR beacon continued transmitting with the callsign VE0EXP, and the ship could be followed on its voyage back home, down the Pacific Ocean, through the Panama Canal, and up the Atlantic Ocean.
I've done several blog entries about the C3 expedition, the Polar Prince, and its WSPR beacon, and you might be interested in reading them; just follow the "Canada C3 Expedition" link under "Tags" in the bar to the right.
I've been able to catch the WSPR beacon of the Polar Prince on the 40m band on many occasions, from its voyage up Canada's east coast as well as for a large part of its leg through the Arctic. During the leg through the western part of the Arctic and down Canada's west coast I was unable to receive the 200 mW beacon, as were most of the other European WSPR monitoring stations.
But I had set my goal to catching the Polar Prince at least one more time, on its way back while doing the Panama Canal transit from the Pacific to the Atlantic Ocean! And I succeeded!
With my homebrew magnetic loop on 40m I catched the Polar Prince while it was west of Middle America, while it was waiting to enter the Panama Canal, and inside the canal itself! I caught the Polar Prince in grid locator FJ09dc in the early UTC morning of December 28th, 2017. This grid put the Polar Prince inside the Panama Canal close to the city of Gamboa. Below you'll find a photo of the canal at Gamboa. Gamboa originally was built to house the Canal Zone personnel and their families during Canal construction.
The Polar Prince WSPR beacon since the start of the C3 Expedition in June of 2017 has been on the air uninterrupted! Well almost, as during a port visit of the ship in Halifax early on in the C3 expedition, a visitor had been fiddling with the buttons of the QRP Labs U3S WSPR beacon and failed to return the U3S to its correct settings. This was soon resolved though. Another interruption occurred on the ship's return home. On January 4th, 2018 the Polar Prince suddenly dissapeared from the WSPR radar. The ship was crossing a severe storm in the Bermuda Triangle (!) when the signal got lost. Antenna damage was the suspected culprit. Later it seemed the U3S had fallen of its shelf, resulting in the power chord being unplugged and the VE0EXP beacon going off the air! But, as mentioned before, the VE0EXP beacon transmissions resumed, and can still be heard from the ship's homeport in Lunenburg, and hopefully we might be able to track again on the WSPR HF subbands the icebreaker on one of its next voyages.

In the early morning of April 6th,2018 on the 30m band I finally also managed for the first time to be spotted by GM0HCQ/MM aboard the Royal Research Ship James Clark Ross in the South Atlantic. Last summer I was already spotted by the James Clark Ross on its Arctic voyage (read about it in the blog entry here). This time the James Clark Ross was located in the South Atlantic very close to the island of St. Helena. It's currently returning home to England from its tour of duty in the Antarctic. I had hoped to be spotted by GM0HCQ/MM earlier in the Antarctic season from Antarctic waters, or more recently from the highly fascinating and utterly remote Tristan da Cunha Island, but that unfortunately seemed to be out of reach for my 200 mW WSPR beacon and mag loop setup.

James Clark Ross Radio Officer Mike Gloistein GM0HCQ keeps an online daily log on his website on http://www.gm0hcq.com/index.htm. The April 6 St. Helena update can be found there also (including photos).

The photo below is taken from the GM0HCQ daily update of April 6th and shows St. Helena appearing ahead of the JCR.

In other news, a new kid on the block is DJ0HO/MM (no qrz.com registration) which the last couple of weeks has been making spots on the HF WSPR bands from the area near the South Shetland Islands, Antarctica. I haven't been able to find any information for this WSPR monitoring station other than that the callsign belongs to a Dr. Walter Jörg Hofmann which seems to be the owner / skipper of a sailing yacht. So most likely DJ0HO/MM is located on this yacht. It's quite late in the season for a sailing yacht to be in Antarctic waters (remember, it's autumn there right now, and the Austral winter starts on June 21st), and I wonder if  Dr. Walter Jörg Hoffman is planning on doing an Antarctic winter over. I haven't been spotted yet aboard the yacht, and although it's going to be difficult or maybe even impossible, in the true ham spirit I won't give up and will keep on trying

DJ0HO/MM is the German icebreaker and polar research vesssel Polarstern. For more information see my blog entry here.

  1. Hallo Michael, leuk dat je ook wat aan DXCC verzamelen doet. En dat met 200mW is inderdaad nog extremer. Op dit moment ben ik niet zo aktief met WSPR door drukte prive en werk. Maar af en toe zet ik de spullen nog aan. Het is na 86 DXCC ook moeilijk om nog nieuwe DXCC in het log te krijgen heb ik gemerkt. Af en toe duiken er weer eens nieuwe op. Ik kijk meestal de activity lijsten na en als ik dan iets zie wat ik nog niet heb probeer ik daar wat. Soms is het ook een DXCC die maar heel kort aktief is, wat ik dan weer lees op een blog hier en daar. Voorbeelden zijn KH9/WA2YUN Wake Island en VK0TH Macquarie Island. De laatste las zelfs mijn blog en was een spot via long path op 10m. Zijn mooie dingen, net als jou spot van de zuidpool met de magloop, geweldig... Ik ga die CSV splitter eens even bekijken, misschien handig? Ik hoop dat er ooit nog eens iemand een excel tool maakt om de DXCC er uit te halen. Het zou mogelijk moeten zijn maar ik ben er niet handig genoeg voor. 73, Bas

    1. Hallo Bas,
      Bedankt voor je leuke en uitgebreide reactie! Jammer dat je op het moment wat minder tijd hebt voor WSPR. Het mooie van WSPR, en zeker in combinatie met een standalone WSPR-zendertje zoals bijvoorbeeld de U3S, vind ik wel, is dat het een onderdeel van de hobby is dat eventueel ook kan worden uitgeoefend als je het net even wat drukker hebt en dat redelijk goed te combneren valt met andere niet-hobby zaken. Je zet het zendertje aan en je kunt je op je gemak gaan bezighouden met andere zaken. Als je dan later even tijd hebt, kun je kijken waar je zoal gehoord bent.
      Wake Island en Macquarie Island zijn wel erg mooie "vangsten". De kans om die aan mijn lijstje toe te voegen zal ik wel niet snel meer krijgen. Het wordt op een gegeven moment inderdaad steeds moeilijker om nog meer landen aan je lijstje toegevoegd te krijgen. Vorige week kon ik Alaska toevoegen en daar was ik uiteraard erg mee in mijn sas :-) Het zou mooi zijn als meer amateurs actief zouden worden met WSPR monitoring, ook in landen die nu nooit of zelden op de WSPR kaart verschijnen. Of tijdens DXpedities bijvoorbeeld zou ook mooi zijn, hoewel dat als het grote DXpedities zijn waar alle banden continu in gebruik zijn lastig zal worden. Ik vraag me af hoe we meer amateurs enthousiast kunnen krijgen om actief te worden met WSPR, met name in de landen die nu zeldzaam zijn.
      Als je hulp nodig hebt met de CSV splitter, laat het me dan maar even weten. Excel tooltje om er de DXCCs uit te halen moet zeker mogelijk zijn, maar ook mijn kennis van Excel reikt daartoe helaas niet ver genoeg. 73, Bas!

  2. Jörg, DJ0HO, is an electronics engineer on board the German icebreaker "Polarstern" (not exactly a "sailing yacht"). More information about the ship can be found here: https://www.awi.de/en/expedition/ships/polarstern.html - He uses a Red Pitaya STEMLab 125-14 with an active receiving antenna to monitor up to eight WSPR frequencies simultaneously and regularly uploads reception results to wsprnet.org through the vessel's satellite link. DJ0HO will be on board until the ship returns to its home port of Bremerhaven, Germany, in June 2018.

    1. Thank you very much for this very interesting information, Felix! It's good to see a WSPR monitoring station now also on board the Polarstern! In the meantime I've managed to be spotted on board the Polarstern twice! My 200 mW transmitter didn't manage to get my signals there, so I tried with another transmitter using 5 Watts. Still it was not easy, but I've managed to be spotted twice while the ship was just north of Elephant Island (see my blog entry of May 5th). 73 and thanks again!
