The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

WSPR-Funkbake in der Antarktis

KP4MD/P is active on WSPR until July 12, 2017 from (FK68xk) Carolina, Puerto Rico, on the north shore of the island.
Radio: Elecraft KX3, 5 watts on 20, 30 and 40m.
Antenna: Buddistick monopole at 24m elevation over the Atlantic Ocean.

Possible false band reporting Problem when using Band Hopping and "Tune" Mode with latest WSJTX or JTDX.

Anyone confirm ?

Going to try some low power mobile WSPR and see what happens.

2016-2017 season on 160m WSPR is now over.
Last NA/EU dx spot dates back to June28, the first one Jul04-2016. Season was amazing with a series of all-time record activity.
Three figures to remember:
- best all time session was Jan08-2017 with 435 unique NA-EU dx spot (see
- number of session with NA-EU dx spot: 317 nights (272 previous season)
- 484 stations (NA+EU) were able to listen to a station on the other side of the Atlantic (193 previous season).

Just hit the US from Rotterdam with 0.5w!

Running an experiment at least through tonight. I'm running 1 watt to a 40m Hamstick at 6 feet on a tripod, with 3 15 foot radials under it. Running WSPR2.12 and a Softrock SDR using HDSDR.

WSJTX 1.7 installation appears to work fine on RPi2B with Ubuntu 16.04, a bit slow on JT65 decodes, but to be expected, I used image with ssh installed so could avoid using connected monitor and keyboard. Then installed VNC and gnome so can use remote GUI for access. Only problem so far is incorrect keyboard mapping when trying to fill in callsign and locator text boxes. Got round it by cutting and pasting from terminal window. This would be a big problem for a chatty protocol like psk31, but not for the minimal text jt protocols.

Using WSPR TX Shield.

Software: and Raspbian Jessie

If it keeps crashing after a few times, read

Works well.

Try sudo wspr -s -o -p -4.5 callsign locator -r 20 20m 0

Txs every other.

I'd ignored this mode previously, but then, I'd been at a QTH where antennas were possible. Now in a first floor flat I'm just amazed at how far 1 watt will go from a random length of wire stuck in the window, fed against the radiator pipes via an ATU. What a mode.

Well I have been working on a Bitx40 TRX for around 2 months now on and off. Well mostly off to be honest.
When I got it,it would not transmit. Two faults I found. One was my doing as I didn't understand that the PA had a separate power supply rail but the second one was a poor solder joint on the bias pot. So soon had it working but only 2 watts and not as stated 7 watts.

Currently running only 5mw on 40m and am amazed at how far away the signals are being received.
The antenna is an MFJ magnetic loop at just 2 metres above ground level. SotaBeams WSPRLite is the moving force (or should I say "whisper"?).
I will keep on 40m for a day or so longer and then see what happens on 20m.

Testing an FT-991 5w with EndFed Monoband Wire antenna 20m @ 15t

That is the "advice" given to me by older "wiser" UK Radio Amateurs. It's all ground-wave - no good for DX during a sun-spot minimum, they say. At a local Amateur Radio club, the members turned their nose-up at a suggestion of a local 10 metre net. "It will not work, people are too far apart, better off to use VHF", they complained. And therein seems to lie a pathological dismissal, and almost hatred, of 28MHz in the UK. WSPR has proven them very, very, wrong!
