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.

Running 24/7 WSPR beacons receiver on 40m with minimalistic setup: SoftRock Lite 6.2 RX, PA0RDT mini-whip antenna and WSPR 2.11.
It works fine!

Well after trying the FT-817 and getting nowhere with it I opted to try out my FT450AT and have it partially working.. Sadly TX'ing seems to be missing right now but maybe useful for reports to others :)

woke up early this morning, set up WSPR on 30m and - after a single TX period received 26 reports:

Yesterday, at approximately 1730L (2330 UTC) near Denver, Colorado USA, my system reported a signal from a station claiming to be in the Antarctic.

I performed a database query searching for this call sign being received elsewhere or appearing in the database as a reporter. Nada! This call sign does not appear anywhere else in the database over the previous week.

I've noticed the odd WSPR signal right at the bottom of the WSPR display lately.
They indicate good signal strength and timing, but WSPR does not decode them.

I checked my WSPR setup with a counter locked to GPS and my WSPR tuning signal
appears to be within 0.5 Hz of nominal.

I then tuned my receiver down 20 Hz and was able to decode KZ8C and KI7AB.

Moral of the story: If you choose to transmit near an edge of the WSPR sub-band,
don't expect everyone to decode you.

Since October 2011, I've been running a Flex-1500 software defined radio in the WSPR frequency hopping mode coupled to a 40 meter full wave horizontal loop through a 4:1 Guanella balun with no other impedance matching. The standing wave ratio on the WARC bands was significantly over 3:1.

Name is Tom and I just installed WSPR 2.11.
I think I have it all setup correctly
I will see if I can hear and if anybody hears me.

Rig is a FT-857d with SiganLink USB and wspr 3.0 under openSUSE 12.1
I am seeing multiple images of the same station. The signal is pretty hot in here.
Do they have a image problem with some type of SDR or it it on my end?

Hi Group

Yesterday I started receiving in WSPR again after a long pause of not being active in this mode. Unfortunately I only could be active by receiving in case of some "internal problems" with other rf-equipment nearby my wire-antenna.

Maybe I get my pappradio running again with wspr - at the moment it wouldn't receive any signal in WSPR... Must be a problem with Fiq-frequency or something with "swap i/q-channel" I think.

It's very difficult to find the cause of this but I am sure I would find it some day.

For those of you who do not have a Software Defined Radio and would like to monitor the incoming WSPR signals on a sprectrum analyzer, try this one, works great!!

Hi, W7FJ put up a video of my VCXO-AXE using a GymBoss as a timer:

I also want to point out that there is an accessory timing board that I developed
which I have used for over two months continuous without synchronization loss.

Anyway thanks to a user for the youtube video; thought others might be interested.

Hi all, just to let you know, a while back I created a Facebook group for 160m WSPR enthusiasts. There is a few people who have joined the group from different countries, its quite good and easy to advise of your activity and meet up with friends with similar interests.

As a bit of an experimental thing, I thought I would make some group pages for those interested in 10m WSPR and 6m WSPR, just to see how it would go and give those on Facebook an interest group that caters for them too.

I finished the receive portion about a week ago but for the life of me could not seem to pick up any signals. Had what seemed to be signals on scope / waterfall but nothing decoding in any software.

Last night I went out and got a set of speakers so I could hear as well as see what was going on. Tried using a headset before but can't really walk around the house with them:)
This way I could just let everything run and come to the radio if I heard something.

I built a Softrock RXTX Ensemble transceiver for 40m/30m/20m. Running it with WSPR 2.11 r226, I made my first contacts with the transceiver today, running it with a pack of rechargeable cells, wired to a Creative EMU-0204, with no PowerSDR or VAC. I will be describing my setup in a separate entry soon.

Dear, it's a 3rd day in a row I am able to hear as well as am being heard by VK0TH Travis at Macquarie island on 30m/WSPR around 21-22z. Wish we could try JT65-HF one of these days while conds last yet...

Been tinkering with Ham radio for over 30 years, got licensed in 1982. Since those days that have gone by I have tinkered with SSB,PSK31,JT65HF,HELL Modes,and recently found an interests in RTTY.

I live in the Philippines at the moment with my wife and son, and I usually spend alot of my free time operating on the bands. Last few years its been 6m as well as the others. I find the hobby to be very rewarding and more enjoyable than anything else.

Here I am...first time logging on the wsprnet! Glad to be here. I will be on the learning curve for a while but hope to get talking to some of you folks out there. I am only on 30m with a small j-pole antenna, so I don't know how many folks I'll be able to talk to. Best wishes to anyone reading this!


Last night I compiled, and wrote a quick how to compile WSPR 3.00 under Debian testing (wheezy) amd64 and the problems I encountered in the process.
