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.

Great event this night (Feb13/14); Jim KP2XX was heard for the first time in EU:

2016-02-13 23:54 KP2XX 1.838116 -24 0 FK78ni 5 ON4LUC JO20 7026 42
2016-02-14 01:28 KP2XX 1.838117 -30 0 FK78ni 5 F59706 JN07th 6759 45
2016-02-14 02:16 KP2XX 1.838120 -26 0 FK78ni 5 MW0PPM IO83ia 6499 38

Jim heard 9 EU stations: RX3DHR, DF1VB, PA1RZ, DJ3KJ, ON4LUC, M6VPW, G0LUJ, MW0PPM, GI4OYM.

"...'My season' ends after next weekend (13/14 Feb) because the land owner needs his property, where my Beverages are located, for horses..."
Remco (PA3FYM) has announced the end of its season on 160m. I think he has marked his first and short season(Nov24/2015 -Feb14/2016) by his participation in the activity "across the pond".
Over this period he has decoded 33 North American stations with beverages for the RX Challenge.

13/02/2016 Finally persuaded the FDM-DUO (and FT-991) to work satisfactorily with WSJT-X (WSPR)so now band hopping running 5w to the Gap Titan antenna. Its been well worth the effort!

Active night on 160m : 669 dx spots "across the pond" in the data base, 38 stations in the round.
9 NA stations heard in EU: AB4DF, K1BFS, K4RCG/4, K9AN, K9PAW, KD6RF, KJ4YBS, N1NCO, W9MDO
Best Rx stn: KK1D(14EU), K4RCG/4(8EU), F59706(8NA), G8DYK(6NA), PA0O(6NA), G0KTN(5NA), G8LCO(5NA), ON4LUC(5NA)
To note a new one heard for me (K1BFS) and a new count for my NA rx Challenge: 47

Whilst WSJT-X 1.60 works very well with CAT control, version 1.7 can have grave problems. The development of the WSPR Challenge ( has drawn attention to the severe database corruption that 1.7 can produce when the CAT looses sync with WSJT-x. You only have to look at the results of the band rankings to see that there are very odd scores that are due to cross band contamination.

Built Hans Summers Ultimate 3S kit over the Winter and got my first spots on 40m and 15m with an Alexloop setup on a tripod in my Kitchen. I live in an Urban condo, and the ability to get a signal out of my kitchen, through the windows and down to Texas just goes to show there's alot of opportunities to enjoy this hobby even with the most limited power and limited antenna siting constraints!

SoftRock Ensemble RXTX Kit Built for (40/30/20 Meters)

The first testng done with the unit after building and configuring the software was with WSPR (Weak Signal Propagation Reporter)

If you’re looking for a kit that will help you learn about SDR (Software Defibed Radio) and possibly up for a challenge with SMT components and IC’s, winding your own inductors and don’t mind using a magnifier to see with! Then I would recommend this as a neat project and a nice little receiver or QRP transceiver.

I test today on 160m with 10mw HF at a 6 m long vertical antenna.

Currently have a Raspberry PI 2 (Jessie) running WSJT-X v1.7(dev)
with CAT control of my FT-847
listening and reporting on 20m during the day and 40m/80m at night.
The antenna is a sloping dipole in roof-space for 20m.

Building a Sky-Pi by (RadWav) transmitter for 40m so need to put together an antenna for 40m soon.

IMHO server is now running very well.
It is fun agn watching WSPR reports.
Sometimes a DX cluster like interface would be nice...


WSPR is so cool that it is (but is becoming "was") my favorite mode.

Real propagation science is done, real antenna measurements are made. A quick place to look to see if a path is open to a DX location. A great way for city-bound or HOA-limited hams to see real world-wide contacts.

And, it is (or was) a nice place to recommend for newb's as well as a place to re-invigorate interest for the old-school ham.

I'm still fairly new to Amateur Radio and related web systems.
I'll be reading up, but any suggestions are welcome.

This is an inexpensive project based around a partially built $21 SoftRock Lite II receiver and an $8 Si5351A module. The transceiver provides single band operation between 630 and 10 meters. There are many transceivers in the marketplace that provide good performance at a reasonable cost. However, I enjoy building and experimenting, so I documented this project to share with those who have similar interests. Additional information is located at:

Perhaps in the future there will be an I/Q processing feature in WSJT-X. Until that time, I chose to use a dual op-amp I/Q signal processor. I documented this project to share with those in the WSPR community who enjoy building and experimenting. The project is located at:
