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.

Just arrived with me is a Yaesu FT-817 and a WonderWand 4010 mini loop. Let the portable fun begin.

Well sat and built the filter kit for my wsp today. all sorted. lets see how top band works.

31.12.17 Very pleased that within 24h of starting tests on 6m I got a spot 855km away in Copenhagen with just 100mW

I test WSPR-X software.
It do not decode! I see message box:
"At line 34 of file wsprd.f90 file: "Files\wsprx\save\171230_1154.c2"
Traceback: not avaiable, compile with -ftrace=frame or -ftrace=full Fortran runtime error: ////////// "
What is It?

Hi Guys,

I'm starting to run WSPR 2 days ago on 40m only with 5w into an inverted V from JN38AS.

All the reports are welcome. See on QRZ.com for the contact info.

I finished the construction of my loop this weekend, made the connections to the receiver yesterday afternoon and started listening to 474.200khz. I was pleasantly surprised this morning when I woke up, I received PA0A in the night, my first station on 630m. the antenna is oriented in a north-south direction. Excellent experience for me. 73 and happy new year 2018!

HELLO

i turn on my wspr station this night on 40M. You can send report via email : vincent.f4cvq@gmail.com

Best 73 from F4CVQ

2W in a vertical antenna (2m from the ground.

For me activity and fun is still there and even better on 630m !!
To date i heard 65 NA stations on 160m and 10 on 630m (On Dec-25-2016, 61 NA on 160 and 6 on 630).
I hope your satisfaction goes in the same way you are rxing or txing !!
GL all for the rest of the season, great fun to come...
73, Patrick

Is there a way to correct reception reports in the data base? My fumble fingers showed quite a few spots last evening from my Yacht off the southern coast of Chile when it was in fact it was a grid square fantasy moored securely in downtown Tucson AZ. Cheers and 73, Jim

Nice wspr last night with my bitx40 did a great job of reaching out under 2w!

What happens to the decoding signal, with QSB?
The essence of the experiment:
Turn on the receiver in the given time and look at the WSPR decoding.
1) Receive for 1:30, 1:00 (full signal around 1:50). Decoded! :woohoo:
2) Receive for 0:30. Does not decode.
3) Receive within 1 minute, shifted relative to the start signal for 30 seconds, i.e. from 0:30 to 1:30. Decoded!
In the picture a visible signal (1:50; abbreviated: 1:30, 1:00, 0:30; 1:00 with an offset).
The result:

This last week something odd happened.

WSPRNET would previously (I think this is how it works) add the last two digits on my locator square if known in it's internal database
on my transmissions. ***( I only transmit, and with a bunch of G0UPL ULtimate TX's).***

It no longer seems to be doing this.

I am in JO01MI, it now only reports JO01.

The set up here is a pair of G0UPL U2 rigs, and a U3 rig, all with their own GPS (no single point of failure) and nothing whatsoever
has been altered with then for about 4 years.
