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.

Ive joined WSPRnet to analyzer my new antennas. I have been licensed nearly 40 yrs. After 8 years away from the hobby I returned in 2013. Finally, 17 years after I poured the concrete for my big tower I purchased

We issued a new version of the WSPRlite config app today. This corrects a bug in our random frequency assignment algorithm.

We have also issued the Config app source code for third party developers.

Hi All,

I'm driving from Perth (Western Australia) to Adelaide (South Australia) and along the way I am setting up four WSPR transmitters with the following details:

I've had a Soft66LC4 for ages and never really used it for anything. Currently using it with a magnetic loop. Will see if I can get it to work.

Running the RPi3 with the TAPR shield filter board. Using my BigIR antenna. Looks like it is working very well!
Anyone else running the same set-up?

For those times when you're without access to network time or a GPS unit.......

This small program allows you to listen to the radio, click a button when you hear other’s start to transmit, and zero your PC or Laptop’s clock to the nearest minute or even-minute. This procedure usually gets you close enough to start decoding and making contacts.

You may find that you can get closer to “real” zero by clicking a second or 2 early on the next go-around, as it seems that most transmissions start a bit after the minute.

Running a Red Pitaya as WSPR transceiver since 9th of Jan 2017.
RX antenna 6.5m wire in 1.7m height via UNUN on RX-1 in. RX QRG simultaneously on:
- 2200m
- 630m
- 80m
- 60m
- 40m
- 30m
- 20m
- 15m

TX antenna Hustler 4-BTV ground mounted:
- 40m with 10mW every 10min

630M 1/4 WAVE INV L UP 100 ft approx.
160m 1/4 WAVE INV L UP 100 ft
40m one ele QUAD N/S up approx. 70ft

We finally have stock of our WSPRlite system. WSPRlite is a small standalone WSPR transmitter that covers 20 thru 160 metres. When used with our analysis website , WSPRlite provides a unique way to compare antenna systems in real-time. The basic facilities of are available for all WSPR users to experiment with.

Hello from Peter VK6PK

I was first licenced in Feb 1967 as G3WCJ and still hold the call today (ex Gosport now Birmingham)

In 1979,VK6PK was obtained, and in 1981 lived and worked in Kalgoorlie.

I was very active on ARQ (VKPK) up to the passing of my father (G4UDS) when I retreated to more conventional modes of communication.

After a year or two in the Perth suburbs, I moved with my wife to Wooroloo, which is situated 65 Km east of the city of Perth and nestled in the Perth Hills.

New record activity with 465 UNIQUE dx spots "across the pond" (previous 435 dxspots Jan07).

My 24m tuned tower working verry well for dx on top band

Hi: This probably as nothing directly to do with WSPR, but has anyone nothing their PC clock, and hence decodes, change after playing videos? I just watched maybe 10 short videos, and my clock drifted 5+ seconds! That's within a few hours..
