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.

Does anyone know about rx2oj being active on 80m from IA40
Can't see call on


Hallo everybody !
I´m new here and have the following question:

Have an allmost unused contest-style-station.
For usage in wasted time of unusing think about WSPR should be installed there and work.

Now need some suggestions what to do:
Use WSPR-2 or WSPR-15 ?
Think to use 20 or 40W out for a time of 2 or 4 weeks.

What do you think ?

Very long wanted to build a beacon, many have tried and now I was able to make a fully self-contained beacon. The basis is taken MCU Atmega 328 + DS3231 + SI5351 + PA-1 ВS170. Beacon worked for over a month and during that time had the following results:
CX2ABP - 16673km
DP0GVN - 16160km
RI1ANR - 15508km
and others...

Building installation and start-up: Evgeny Zaryanov (UB0AGX)
Software: Alexander Sholohov (RA9YER)
Other assistance: Igor Lavrinenkov (R2AJA)

New record activity with 784 dx spots "across the pond" (previous 760 dxspots nov29-2013).
45 stations in the round.
8 NA stations heard in EU: K3RWR- K4RCG- K9AN- KD6RF- N1DAY- N2HMM- W1CDO- W8AC
4 EU stations heard in NA: G0BLB- G3RCE- G8DYK- M6VPW. Curiously only G station !

Best Rx stations: G8DYK(8NA), PA3FYM(8NA), G8HUH(6NA), KK1D(5EU), SC0TID(5NA), EA1FAQ(4NA).

Receiver at JO56cb Aarhus, Denmark will occasionally be receiving and reporting WSPR signals on different bands when not used for anything else.
Last 24 hours was on 20 meters and made it clear to me, that my antenna is best derection SW and NE. Now set to 136 kHz. I'm anxious to see if anything will be received.

Using the latest full day of wspr spots, I created a list that shows which grid squares appear in the most spots. Yesterday, the 10 most active grid squares were:

JN49 45307
JO21 36559
IO91 36484
JO22 33888
JO31 29718
JO42 28409
JN58 26031
IO93 24243
JO32 22065
IO83 21285

The complete list is at

Has anyone noticed this before? The database does not seem to upload spots at 0000 UTC from WSJT-X

Today's lonely decode on 10 meters with poor conditions. Still amazing though.

Now running red pitaya with WSPR software.

Beacon operates on bands 80,40,30,20,15m. Output pwr 0.2w.

Last spot on LA9JO!

Trying out my new 7300 with 2% power. RX seems very good.

First attempt at WSPR on 40m and 5w.

JI1CBW appears on LF WSPR-2 after Oct. 30th 2016.

Many thanks to all those that viewed the receiver design on my blog.
I have now posted a compatible VOX controlled WSPR transmitter.

Best 73 to all.
