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.

I finally got a Raspberry Pi 3 beacon going with the TAPR 20 meter shield going after a long silence. New rig is set up with home brew Magnetic look tuned to 14.097 MHz.

Time will tell how it performs.

I plan to operate a WSPR station during the Great North American Eclipse (https://www.google.com/maps/d/u/2/viewer?mid=1vHDxzC1ILcXralfGJodlP_AcOk...) on August 21, 2017. My research indicates this could be a unique event during the rapid collapse of the D-layer allowing spectacular east-west greyline propagation as the path of totally travels across North America. No, I'm not going to be racking up QSO's as I'll be too busy watching the eclipse!

handle is John.
Located on Droop Mountain, W.V. about 4000 ft. in Space. Most all antennas are inverted "V".
About 28 acres and the best is that Im located in the U.S. Quite Zone near Green Bank were the largest rotatable dish in the world is located.
Noise floor is unreadable, super great VHF site where I also have my repeateer.

Finally got the go ahead from the better half to put up some roof mount tripods so I could set up a 20m dipole at 30 feet and a "EFHW 4010" multi-band 40/20/15/10 by MyAtennas. In looking at the spots I'm really happy with the results because even with the "fair" solar reports with just 50 watts on 40m I was heard into Spain from Utah in the western USA and with just 10 watts I was heard into New Zealand and Australia on 20m.

Hi Guys, I've finally got my Ultimate 3 beacon running. Its beaconing WSPR on 10.140.200 on 200mw into a vertical HF antenna.

Not sure why. GPS module and 1PPS appears to be working okay. Any ideas?

In Siberia R0AGL qth: NO66 installed WSPR beacon for 10m band. At 24/7 the time of work. The output power is 0.5 watts, the antenna is Inv-V. Also on a permanent basis, a 20m beacon operates.

Ordered yesterday and arrived today.

On the air within 5 minutes.

Once I had done the clock synch was getting reports within 30 minutes.

Looks like it's going to be really worthwhile.

STELLA 5 -Caelum HIGH ALTITUTE BALLON STARTS TODAY!

TODAY 19.07.2017 the Ballon STELLA5 gets in the Air.
Its an jointventure with two students from Hamburg.
It is an 800g Latex ballon flying with helium.
The probe transmitts on 30m WSPR, 40m WSPR, 30m JT-9 and 2m CW.

The transmitter is an modified ULTIMATE U3s.

Waiting for hardware to arrive... Ordered a WSPRlite at sotabeams for the start. Additional LP-Filters are under construction

Chasing WSPR for this expedition. Propagation is not cooperating. . .

In a previous posting I wrote that I thought a majority of 20m WSPR stations were having their receive performance substantially reduced due to high noise levels. I suggested that even without a calibrated S-meter or signal source the balloon WSPR stations currently floating around the earth could sometimes be used to assess station performance. I tried to demonstrate some evidence that most 20m WSPR stations do not function as well as they might.

Summer opening on 160m (NA/EU path)
