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 started with WSPR using a WSPRlite running 200mw on 14Mhz from Scotland. I'm pretty much amazed at the range that is achievable running this tiny box and less power than a cellphone. First station in the USA has appeared in the log overnight.

Dear friends! Got the first in my life QSL card from swl13562. For 1 year of hobby in the WSPR theme was much, but it was a very pleasant surprise in the envelope! Many thanks to Ruud NL13562. 73 !!!

Hi all

As others mentioned - the Canadian C3 expedition celebrating 150 years of Canada with 150 day voyage through the famous North passage, started from Toronto yesterday evening. Onboard is a WSPR transmitter donated by QRP Labs consisting of:

Just getting interested in WSPR, trying to get some sort of txrx system going.

Follow the WSPR Beacon from CG3EXP on the C3 Expedition Vessel leaving Toronto on the Great Lakes today. The QRP Labs Ultimate 3 transmitter installed on the Icebreaker Research Vessel "Polar Prince" will be transmitting on the 20, 30 and 40 bands. The Canada C3 is a signature Project for Canada's 150th Anniversary of Confederation this year. The Expedition is a 150 day voyage from Toronto, up the St.

If you're not getting spots and you think your setup is good ... it won't hurt to verify your TX QRG.

Lately, I've been noticing some WSPRs outside of the software's band pass (screen capture attached).

Hello WSPRs of the world.

I am now WSPRing with my new FT-991A and my custom wooden stand which sandwiches my LDG AT-200ProII matcher between two pieces of 25mm thick foam. That has stopped the case from ringing every time the relays click over. Fist time WSPRing tonight with new set-up and the first test transmissions on 40m hit Australia and the USA from England with no trouble. This stuff is highly addictive!!

I will stop WSPR(PM95RQ) because of moving.
I have been operating WSPR for about 4 years.
I appreciate every WSPR stations.

This is a test.
