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.

If you have I/Q working please share your setup. I have failed to get VAC to pass audio to WSPR.

Today with success had two QSO's

I have recently completed a WSPR/QRSS beacon project using an Arduino Mega and DDS-60 signal source.


Spots uploaded from me from 0724 through to 0900 this morning (Sept 7th) had incorrect band data.

They were reported as 80m but were in fact 30m spots.

Apologies once again :(

I just wanted to bring everyone up-to-date on the server reliability issues we have had here at WSPRnet the past few months. Unfortunately, for much of that time, I was not very active either at hamming or at server upkeep because of work commitments. However, I am very actively on the case now.

I am playing with a homebrew Magloop. It's mounted to the metal mast that supports my Solarcon 99 about 1.80 meters off the ground. It's set to a good SWR at 10.140000 mHz with a fixed capacitor.
my Flex-3000 shows it to be -6 to -7 dBm less sensitive than my 30 meter dipole on what looks like a quiet band. It's buried in between lots of metal and wires in a angle of the house. I am hoping I can hear Japan and be heard in Japan on 30 meters with it. I know it hears VK but the house blocks to the north west and southwest and it's very near the house. A / B switching between it and the dipole shows the dipole a clear winner visually in the Panafall and on the S-meter. I'll be running the Magloop for about a week in it's current configuration and location on 30 meters. Also LOL step ladder cap adjustments.

Heard JA last night but not above -17. I am surprised the Magloop worked as well as it did with all the metal, power line wires and stucco mesh it was close too. I resloved to do something about that today.

I moved the Magloop to a wood fence post. The bottom of the loop is 1.96 meters off the ground. There are very few conductive objects around it now and it's supports are made of wood. The 2:1 bandwidth with the fixed capacitor is 10.126900 to 10.150000 it's 1:1 at 10.139200. The noise floor is as low as -119 dBm as indicated in PowerSDR.

The loop is 11 feet of 3/8 soft copper tubing formed into a circle. The fixed capacitor is an approximately 38 inch length of RG-213 center conductor and insulation slid into one side of the open end of the loop and the center conductor connected to the other side of the loop. The coupling loop is a Faraday loop formed from RG-8X.

Last night I was able to use a Kite supported 160m 1/4 wave vertical antenna.

After a few teething troubles were rectified, the kite 1/4 wave worked really well, better than expected actually!

I went from almost hearing nothing from USA direction, to hearing quite big signals. Very impressed. Though it can be quite high maintenance due to gravity and wind variation.

I'll try and use it when I can on 160m.

I have been slowly setting up a WSPR station. I finally figured out to transmit with an IC-7200 after reading the excellent forum post. I have my radio on a dummy load running 5 watts. To my surprise, I started seeing a few reports showing up of stations received. To my BIGGER surprise my station started showing up! Wow! I'll switch over to the real antenna and drop power to the lowest possible and see what happens. 73 Tom WB7EUX Joseph Oregon

I'm going to leave my FT817 on receive on 7.0386 all night. Band sounds very lively. Ant = short longwire in the loft. 72/73 Chris.

Using a newly installed off center fed dipole for my FT 817 WSPR setup. Feed point only 20 feet above ground, but is being heard at one watt output. It will be interesting to see how it fares compared to my tried and true R7 vertical.

Tried 28 MHz WSPR this morning but no signals copied at all.

Just want to inform anyone interested in 6m WSPR that Gary VK8AW is on air now and planning to be on air most days now.
Gary is now up north in Darwin, close up to the equatorial areas.
He is currently running 20W @ 20% but im not sure of his antenna at this stage.
I hope that some people can have a look for his signals, it could be quite interesting to see what happens.

Just for all the 160m peoples info, you may have noticed Ive not been on 160m past few nights, ive not abandoned the band, but have removed parts of the Beverage antenna system as Im completely re-building it.
It was originally only set up in a temporary state just for testing purposes to see if it would work, and it seems to go OK, even though it has been set up quite poorly which would give it low efficiency.

I am ready for listening Europeans stations on LF and MF (2200 and 600 metres bands). Now the static noise on theses bands is decreasing, sure it is not so good as during winter, but I think that it is not so bad actually. I am only receiving here, but if you want to test your transmitter on LF or MF, I be OK and try to listen your transmission.

You can inform me on my adress mail, see it on QRZ.

At last a complete shack rebuild, starting in Oct 2011. All stuff in one place that will be something he he.


One small change: members can now post to the group by sending an email to the following address:

Wow, first time trying WSPR and my signal was heard in Australia and New Zeeland.

All the way from California on a mobile HF antenna mounted to the railing of my 2nd floor town-home patio.

Seems to be some awfully big ears out there!

73 de AI6K

Finally got my Diamond HV-7A up on the patio, and SignaLink USB working.

We'll see if any other station can hear my signal.

I'm keeping my fingers crossed.
