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.

Hi all

The Dave VE3KCL / QRP Labs WSPR High Altitude Balloon is over US and heading for a circumnavigation, we hope! Now on its 19th day, having traveled a total of over 36,000km (22,000 miles), cruising at an altitude of almost 11,000m (36,000 feet). Current location is DM48DA (Utah, US) and ground speed 62 knots (71 mph, 115 kph). See attached map of the path, and see for live tracking and further information and photos.

My apologies too, but all my WSPR reports yesterday 22 October between 1658 and 2004 were on 474.2 KHz and NOT on LF. Sorry for this error.

73, Joe 9H1CG

Sorry but all my reports from 19:12z to 19:54z were in MF band.

Good afternoon!
Since yesterday evening October 21 and until Monday 'October 24 morning, I'm testing a self-built antenna "Multiloop" band 40 meters.
The antenna is located inside the house in my shack.
look in WSPR database if I listened to you .....

regards and see you soon!

Hi All,

I've recently put a KiWI WEB SDR online at my home location in the South West of the UK.

This has a built in WSPR decoder which can be used by anyone who has logged into the WEB SDR.

Just click on the red extensions tab in the grey window on the right hand side of the waterfall display and select WSPR.

This will bring up another window which provides various WSPR decode options.

We appear to be split on 60m. Some of us are on 5.2872 MHz dial, others are on 5.3647 MHz.

I have no axe to grind either way, but working split down the middle doesn't seem to me to be sensible.

just got a report from Japan JA3TVF:

2016-10-13 20:22 DJ0ABR 0.475665 -25 0 JN68nt 0.2 JA3TVF PM74pc 9166 45

never have seen that before, maybe a first contact ?

Many thanks JA3TVF for this report !

Antenna used on my side:
horizontal loop, length abt. 450m with a tuning inductor, height abt. 20m.

Yesterday (12th October 2016) I ran WSPR-2 for around 10 hours using my external homebrew inverted V dipole cut for 40m with the apex up at around 25ft (I know - not perfect!). Locator is IO71, IC-7100 and 5 watts. Mostly during daylight hours and around 3 hours during dark. Received some nice reports including a couple of VK's, a HS and a number of mid US stations which popped up as the sun went down.

ANT = MFJ 20m ham stick dipole / at 15 ft / lQQking EW

Let me start by saying that I really enjoy monitoring the High Altitude Balloon's that are involved with WSPR. Due to the way S series balloon telemetry is transmitted on WSPR,(using the grid locator portion for other telemetry), the spots end up in random locations all over the map.In the past,this has just added some clutter to the map and could be overlooked,now with WSPR op's monitoring the WSPR Challenge, these spots skew the distance reported stats in a big way.
We are a propagation reporting network and, seems to me, we should try to be as accurate as possible.

Seems rather too good to be true ?

Any comments ??


Here is my presentation about WSPR:

Surprise to hear John W1TAG as WE3XGR/3 (part5 license)on 630m.

I plan to spend more time on MF to log part5 calls as probably a new RX Challenge...
I cross my fingers !!!

GL all, 73, Patrick

I have just posted a new design on my blog.
It might interest the techies out there.
