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 to all
I am using WSPR 2.0 under Win XP SP3 OS and browser in use is a Firefox.
Im not able to find me in map. Upload spots is ON.
The problem is new. What does is mean this situation?
Thanks for advice to all.

The N3ZI DDS kit was built some time ago, and I used it for alignment of the WSPR Transceiver. I couldn't get the notch filter adjusted for the correct peak and null. With Christmas and a vacation down south, I set it aside for a while.

Hello,

I am testing a homemade QRPp transceiver
in EA4RCT club station

I will be transmitting next days at 3584.1 kHz
with WSPR v211 200mVpp@50ohm 100uW -10dBm

The WSPR is configured in IQ mode and with a "0dBm" power.

I will be happy to receive QSL at
ea3ghs at gmail dot com

Everyone here knows that WSPR is open source software. The full source code is licensed under the GNU General Public License (GPL), and is available to anyone, under the conditions of that license, at

http://developer.berlios.de/projects/wsjt/.

A number of people have contributed to the development of WSPR. We communicate with each other by means of an email reflector hosted at the above URL.

At least a 3 months break with WSPR at the OH1ZAA-location. In the meantime
we have been following it from the side at OH3MHA (mainly active on 7 MHz).

Couple of days ago decided to change setup which was working for a year already - ZetaSDR+Rocky+WSPR 1.0. Changed to WSPR ver 2.11. The start was not straightforward, finding the frequency offset took several hours and the result is more experimental than calculated. Then tested phase corrections. If somebody intend to use such setup my freq shift with clock oscillator at 14.31818 Mhz is 12980, RX I/Q not inverted and all phase corrections off (I found this option best already but will make more tests).

AL4S and N6SPP/KL7 will be QRV @ KL7AA attempting EME starting at 10:30pm local.

First time out in three years with the gear. Also will do some BARTG RTTY this weekend.

Is anyone interested in scheduled testing of SSB communiation paths on 6,2, and 70cm? You can email me directly at k4nam@embarqmail.com - 73's es gud DX! Tom EM70vn

Increasing numbers of my spot reports do not upload with "attempted access to WSPRnet timed out" messages.
Is the server capacity overloaded? Should we manually upload our stored spot reports to the server to transfer the missed ones?

I have just noticed a typo error in my locator should read IO91UO not IO91OU. I have updated details today.

Apolgies!!

I had some extra time off over the holidays, and although the WX has been cool (-20 oC -ish) the thought that it would be nice to have something for 80m wouldn't leave my mind. On the other hand, midwinter isn't the time to be doing anything large or elaborate outside. I noticed an article in an old copy of TCA describing a dipole reduced in size by folding it into a square. Not a loop; the tips do not connect. For 80m, it's only 10m on a side, and I have a couple of 15m spruce trees in the side yard - directly beside the power line :(.

Just installed the frequency-hopping version of WSPR last night, and left it running on recieve-only. First indications are good, and I'm picking up signals from 80m (hello G4SPE!) to 15m (hello UA3ARC!).

I'm running an inverted L for an antenna at the moment along with an LDG Z100Plus ATU, so until I build some way of triggering the ATU from the machine running WSPR, I'll be sticking to transmitting on a single band for now.

Branford CT FN31ng is QRV on WSPR, 80-10M using Ten-Tec Orion at ~ 10W and a motley collection of dipoles and a 3-element SteppIR (20-10M).

The computer is an Intel Atom 230 CPU (1.6 GHz) with 1 GB RAM and Ubuntu 11.04 64 bit OS.

It seems that Amateurs are allowed to broadcast, as long as they have nothing to say! This is the mode for the tongue-tied ham.

Yesterday i built a new Antenna for 30-Meters. A little Spraycan with 28 Turns on a 50 mmm tube. Please see my blog for details.

as from 17.00hrs today m3uls will become 2E0UAE. Thanks

Have changed my set-up---the FT817 now permanently on WSPR, the TS570 back to flogging cw when my pacemaker allows it!

Hi everybody

Although I am primarily a HF HAM, I would like to use this nice tool on VHF or even higher frequencies. How many stations are active on 2m / how is the experience with WSPR on that band?

Using the Ensamble II SDR Receiver to receive WSPR from 80m to 10m
http://www.wb5rvz.com/sdr/ensemble_rx_ii/
The soundcard is a 24 bit 96 kHz soundblaster Live.

Antennas are dipole for 80m,15m,10m and R7 vertical with elevated radial system. 6 radials 10m long 2m above ground.

Software used is either the WinradHD or Rocky.
