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 launched WSPR 2.12 on a Pentium 3 1200 MHz PC.
But it can't work normally.

What's it?

One of the interesting things you can calulate from WSPR spots recorded on the WSPRnet web sites is the number of kilometers that each milli watt of power from your transmitter covers.
Using my WSPRLite Classic Transmitter running 200 milli watts into an OCF dipole I made the following contacts.

12-Feb-2018 at 12:28 UTC to K9AN at EN50wc total kilometers 17660.

A calculation to K9AN shows that for each 1 milliwatt of signal the Transmitter covers a distance 88.30 kilometers.

9-Feb-2018 at 20.50 UTC to F5OIH at JN06ci total kilometers 14419

My personal WSPR setup. Raspberry Pi 1 with filters for 80m, 40m, 30m, 20m and 17m. Output is for now 10 mW, but I build one simple amplifier about 200mW (almost finnished).
Till now all working 24 hours on day in a FD4 antenna which is for now very very low over ground.

Wanted to create a single band Raspberry Pi SUPER QRP transmitter.

Bought and built one of these:

Installed it on a R-Pi 3 i had sitting around from adafruit.

Using Jessie Lite as an OS on the RPi i used this software:

Found this site had an archive of historical WSPR data going back to 2008 in CSV format. Since i'm a DBA with backup skill set in BI i wanted to load all historical data into a SQL Server database.

Needed a way to automate download .zip files and found a version of wget that works on Windows.

By using SQL Server Integration Service I created a process to download the current and 23 previous months of .zip files from site, perform an extract and load the CSV data into a table.

Stand alone WSPR 200 mw Beacon from Far North KP69.


Is there modulation such as WSPR, but without using realtime?
I want make automatic beacon, without precision clock.

Over the last week I have been running a WSRPlite Classic on various frequencies into a Buckmaster OCF dipole at an power of 200 milliwatts
the most successful bands here in Western Australia are 40 meters, 30 meters and 20 meters. Spots and 30 and 20 meters have been reported in
Norway, France Germany, England, United States, South Korea and Japan, not bad for 0.2 watts....

New season record activity this night with 416 UNIQUE dx spots "across the pond" and 83 rx stations in the round (23NA/80EU)
Best EU Rx: G8DYK(16NA), G4WLC(16NA), F59706(15NA), LX1DQ(14NA), ON4LUC(13NA), G0LUJ(13NA), EA8BFK(12NA), OZ2JBR(9NA), LA3JJ(9NA), DF4PV(9NA)
Best NA Rx: W1FRA(17EU), W1IR(15EU), K9AN(12EU), K4RCG(12EU), WA9WTK(11EU), VE3LC(11EU)

Congrats to John(G8DYK) and Frank(W1FRA)

Last few days i received 4 times OB2Z on 40 meters.
Another dutchman and a german received OB2Z, both one time.

OB2Z looks only active on 40 meters.

This appears strange to me, has anyone any info over this callsign ?

First NA signal received.

The 630 Meter Ham band is alive and well in North America with new stations
Being reported almost every day.
Many N.A. stations being heard in Alaska, Hawaii, EU, Cayman IS, EA8, YV7MAE and more.
