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 want to apologise for incorrectly posting 6 meter contacts when in fact they were 30 meter contacts.
Seems my PC and FT847 stopped talking to each other. I do not know what can be done to correct the data base.

Sorry for any inconvenience. Cheers, Dick

I will be testing my 17' Vertical at 1 Watt on 20m during the day today (9/16/2013) using Elecraft K3 and SignaLink. My location is FM18qt south of Annapolis, MD and west of Washington, DC.

I will take matching heard/hearing contacts and upload to LoTW during the week.

After the windstorm that broke his previous antenna, Mike is back last night with a "160m full sized vertical". I try to imagine !!
Despite poor conditions, Mike is the only one NA station crossing the pond and now take place in my 160m challenge list with 1W.
In the night Jaap (PA0O) had opened the way.

I've just made dedicated 20m WSPR machine.
Using AD9850 dds and its 125MHz clock is GPS disciplined.
TX final is 2SC1306 so, power is maximum 3W.
Now, I'm testing on the air.

I will test 6m WSPR beaming to south at around 10:00z.

Frits (W1FVB) gave a good example of fine tuning of window time, % time tx and pwr TX:

The last few days (Friday to Saturday) has seen a very bad rain storm, hitting my part of the U.K. infact our village was cut off for some hours due to flooding.. At some point during the storm the CFL died .. I think it was water ingress into the matching unit, I will carry out a post mortem when I can get the aerial down to ground level, in the mean time running I'm running a small HomeBrew active aerial at ground level RX only.
Regards Paul.

hi Jay VE3SWS-

Very good on the "real 2 way" qso mode! It was popular a few years back, but slowly faded away partially due to the long transmission sequences.. If you don't mind trading in the 5.9hz width sigs for something slightly wider- take a peek at the semi-new mode in WSJT-X ver2 called JT9-1. This popular 2 way qso mode's sigs have a width of 15.6hz, and a transmission time of 50 seconds.

WSPR 2way q's were typically found on jt65a channels, with a df around +300.

You can find JT9 sked activity on "", and "".

Spots reported by la5zl thursday between 07z and 09z on 15m.
was actually rx'ed on 20m.

Excellent night session on 160m WSPR with great opportunities and so, great spots!!:

Hi Chaps,
Ran the CFL last night on rx test, with a very low tx ratio. This CFL is now mounted at approx. 8 meters ( 25 Feet ) above ground. It was setup up on 7.040 Mhz, where the bandwidth is much more than I expected, over 100 KHz. This little aerial is only 40cms (15 inches) in diameter. With this setup in the horizontal mode, this tiny aerial heard two Vk's and several east coast stateside stations plus various European stations. At Midnight 31st August this little setup goes on line for an extended test on 7Mhz.

( Softrock Ensemble @ 500mW )

This modification to GM4ISM's Excel Spreadsheet polls real time WSPRnet data and estimates the signal path quality for various communication modes: WSPR, JT65, Olivia, PSK31, CW, RTTY and SSB. These charts show expected signal dB over threshold on these modes with user-defined transmitter powers and relative antenna gains. The values below threshold are in red, above 6 dB in green and intermediate in yellow.

Running 3w to ATAS-120 mobile antenna on 20m daytime.

Tried my first ever transmission on WSPR this evening. On the very first TX period I got this:

2013-08-26 18:10 G0LRD 14.097194 -24 0 JO02 1 HS0ZLG OK03gr 9435 74

9435km from 1W into a poorly positioned 20m off-centre fed dipole. Very pleased!
