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.

I am not an ARRL official, but in my opinion there is no question about it: WSPR spots, even if they occur both ways between two stations, do not constitute a QSO that is valid for DXCC or other awards.

A minimal QSO involves the exchange of information between operators, with appropriate acknowledgments. These things do not happen with automated WSPR transmissions and receptions.

What are the latest rules regarding WSPR exchanges and DXCC qualifying "QSOs"? I hear a rumour that ARRL will accept confirmed WSPR exchanged reports (he hears you and posts a report and you hear him and post a report to the database/by QSL card?) as a valid DXCC exchange. I.e. this is a mutual exchange of reports using, for example, WSPR2 and not necessarily the QSO mode in WSJT.

Is this correct?

Certainly an exchange of details via WSPR contains far more information than a DX contest exchange on HF which IS valid for DXCC.

Don't forget like I did, make sure you give WSPR2 Admin. Rights.

Or it will load up with 30M and not the band you thought it was last on.

I love Vista, it protects my computer, but you always have to set Rights for all programs

you want to run.

Sorry for all the wrong spots today. ( a handful)

A brief addendum to my email of yesterday, announcing that WSPR 2.0 is available at the WSJT web site.

WSPR 2.0 provides easy access to a new online User's Guide, . The User's Guide will be a "living" document -- in other words, it may be updated whenever I have something useful to add.

Just been showed this whisper mode by a fellow ham and i must say i have got the bug now,
I think it's a great mode for plotting your antenna (my weakspot has to be into the USA (don't know why as i have a rotable dipole but makes not a lot of difference when i point it over that direction)

Any how the long and the short of it is i can try out different angles with my wire dipoles and see which one is working the best

Installed WSPR 2 yesterday. So while I was at it I decided to read the instructions! What perplexes me is the Rx noise indicator. The instructions tell me to try to reduce that to as close to zero as possible using the RF gain and AF input volume to the computer. Neither adjustment makes a blind bit of difference to the Rx noise. It's always -30 Db. Never changes, apart from when in Tx mode of course.

Have I read the instructions wrongly?

WSPR 2.0 is now available for download from the WSJT Home Page,
Click on WSPR in the left margin, then on the appropriate WSPR 2.0 link for your operating system. Installable binary packages are provided for Windows and for recent Debian-based 32-bit Linux systems. A recommended Linux distribution is Ubuntu 9.04.

Version 2.0 of WSPR introduces a number of new program features, including the following:

A few more significant changes to the site today:

1) The chat page now uses user information set in fields from the user profile under "My Account" -> Edit -> WSPRnet. The old "User Info" link, which fetched and stored data from a different place, is no longer used. If you haven't done so, please fill out the WSPRnet info fields.

Hello All,

This subject might have been discussed before but I like to bring it up once more.

The present WSPRnet program has capabilities to plot its data versus time, such as the number of receive reports.

The WSPRnet database contains data that could be used for propagation plots for a particular station to and from

other participating stations and well in semi real time.

Is it possible to add the ability to plot the received signal reports ( in dB ) over lets say a 24 hour UTC
day between 2 or even more than 2 stations.

I'm in the process of doing some improvements to the database and associated code, and I wanted to explain several things I did today. Joe (K1JT) is in the process of developing a new version of WSPR, and some minor schema changes were required to support some of the new features (I won't give anything away at this point!). That's what I was just doing during the 30-minute work tonight.

Since I put some WSPR reports into the HRD log to analyse it, something went wrong. Coincidentally I sent the reports to eQSL. I deleted the logs, but anyone who has received a eQSL from me for a JT65 QSO can delete it. Sorry for the inconvinience.


Was not able to upload manually so some of the files are included here as attachment:

I've been in Ham Radio since the 1960s.
I was active on RTTY in the 1970s with a
microprocessor based bit banging terminal
using modified Sidereal Muicronet II hardware.

The unique tools provided by the WSPR system
have awakened my interest in HF propagation
and antenna issues. I finally put up a 130
foot Van Gordon dipole I bought some ten years ago,
and put my Dentron SuperTuner back together.

Now I understand why hitting Europe from the
Oregon Rainforest is so tricky - it's the
auroral oval that is in the way.

Started Ham Radio activities, during Electronics Engineering course in early seventies when worked about 40 + Countries in 160 meter band, using a building top dipole and converted HF aircraft radios.

At this time the commercial Rig availability was limited and used Bendix TA12, Marconi TX and Command Sets.

Went to USA several times and had the honour to be personnal friend of W1BB, Stewart Perry.

Had PT2FRU, PT2CW and "A" Class, PY2CW since 1979.

Operates mostly from a mobile shack installed in a Winnebago Motor Home.

By curiosity, I have noticed some spots ( their are not unique, one can search in the database ).
