PA7MDJ's blog

The past two months or so DJ0HO/MM has been making spots from the area around the Antarctic Peninsula and the South Shetland Islands. It surprises me that almost no information can be found on DJ0HO, that no information about the DJ0HO/MM operations came out in the WSPR community, and that as far as I know nobody did any inquiries as to the background of the Maritime Mobile station. I did some research and I have good reasons to believe DJ0HO/MM is located onboard of the German research vessel RV Polarstern.

Today I did a WSPR monitoring session on 20m. I noticed that a lot of European stations were hearing HZ1SK. I did not. Then I noticed that there was a strong signal in WSPR 2.0 on the same particular frequency that just everytime did not result in a decode. The frequency was close to the one in use by HZ1SK. Then I started WSJT-X to see if maybe this program would produce a decode. It did, and it indeed was HZ1SK, which now in WSJT-X was decoded every time. I ran both WSPR 2.0 and WSJT-X simultaneously and again WSPR 2.0 failed to decode. Why?

Sorry, all spots from PA7MDJ on 2018/02/17 between 1516 and 1518 UTC have the wrong band reported. The band reported is 630m, it should have been 30m.

Sorry, all spots from PA7MDJ on 2018/01/25 between 2234 and 2252 UTC have the wrong band reported. The band reported is 20m, it should have been 40m.

For more information, see also my previous blog entry (of July 6th, 2017) about the Antarctic WSPR beacon.

The past days I've been receiving WSPR beacons on 40m from G4BYO. I noticed the grid locator being quite odd for an English station. The locator (IL16 yesterday, IL04 today) put G4BYO in the Atlantic Ocean somewhere south of the Canary Islands and west of the Western Sahara. I immediately expected a sailing yacht. Callsign G4BYO belongs to mr. William Tee. Googling this name brought me to this webpage: https://cornellsailing.com/sail-the-odyssey/islands-odyssey/rally-2017/m....
