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.

Hello all,

I realized it's quite difficult to find precise information about defined WSPR frequencies for all available bands. So I wrote a list for all bands, here you go! The TX frequency center is always +1500 Hz above the dial frequency.

last update: 2018/01/18
----------Band----------Dial Frequency----------TX Frequency center(+range)--------------

Today is my first day into the WSPR net.
I am working with one icom 7300 5 watts and dipole antena into WSJX software.

Good vibrations for first time

As is my habit of leaving the rig on into the eve to monitor, heard some activity on 160 tonight. Into Philly between 02:20 and 02:34 UTC I caught -
K4RCG -16
W8AC -17
VE3CIQ -12
K9PAW - 27 (nice call!)

Just bought, setup and running the WSPR Lite from SOTABEAMS.
I'm using 200mW on 40 meter, vertical home made antenna (that can be improved; swr about 3:1 !),
I have been successfully logged by many stations (DL, G, LA, EA, EA8 ...) and several US stations like this :

2017-09-28 00:06 ON4LAO 7.040129 -25 0 JO10rn 0.2 KM4ALP EL98jq 7228 285

I'm very impressionned ... propagation wave is very exciting
VY 73's ON4LAO - Pascal

I had thought it a peculiarity of my antenna, though vertical, to radiate primarily to Western Europe; I don't know if it is primarily only Western Europeans that are using WSPR on 30m in this "Old World" area, but a few days ago, I had made a blog post about how it appeared 30m was "afraid" of the approaching nightfall, concentrating more and more intensely in Western Europe as Grey Area approached... But now as I watch 4Z4TJ's results on 30m band on the map over the last several hours reveals the same exact radiation patterns as mine basically on 30m...

Beside the WSPRlite tool
there is also a free site

Now qrv with WSPRlite
200mW , 30m , Dipole.

Anybody knows details of device hardware ?
Looks like it's all done with a PIC32MX130F256B.

After a period, (about 20 years!) I have started operating again with renewed interest.

During the time of inactivity, I had a small stroke which made chatting verbally, which was always a problem for me, even more difficult so I was delighted on rediscovering ham radio that everything had moved on and a large part of it had become much more computer orientated which suited me because as a professional computer programmer this met my needs excellently.

I have been running WSPR successfully at 0.5 watts on 20 metres, on and off for a few months.

Usually it will work for a few days and then stops uploading spots to the web site. I get the error message in the attached file. WSPR continues to transmit and I continue to be reported by receiving stations. I continue to gather signal reports, but they do not get uploaded to the web site.

It looks like a program bug. Maybe someone can look at it and fix it?

Ran rig on 40m last night and got a nice TU in chat from K4RCG for the spot (he spotted me twice as well) on a new antenna he had just put up. I normally would not have even had seen that posted if something hadn't 'led' me to click on the chat button this morning right before switching Rig to 17m; that, in addition to the regular commenting on my blog posts, well, that makes me feel I am doing something for somebody, and I really appreciate that and feel welcomed and accepted and appreciated, TU guys. :)

Nada, zip, "shum davar", "klum"...

I knew that none of the bands are doing so great right now, or so, everyone is saying... of course, it is all relative... I'm sure conditions are quite good compared to the times when you only had a couple thousand hams globally and you actually had to work quite a bit to make any contacts... hence the term, "working on 20m," etc...

Starting the WSPR on 20m tonight at 19:58z, 2017.09.22... not much going on as I expected... I believe 20m is a band that can also open up at night, though less so than 30m, and much less so than 40m or 80m... I am assuming that 20m probably opens up more at night time during the colder winter months?? But I could be quite wrong about that...
