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.

Tried WSPR for the first time today had so issues with the software but seems to be somewhat ok now. Saw a lot of stations on 20M and 1 on 30M will try to get on more to fully check it out.

While setting up for WSPR ops- the first time in a long time- I noticed a lot of "racket" (noise) just before and after the WSPR program transmits its audio tones.

Some further observation found that; regardless of the WSPR program, my FT-857D (s/n 4J31...) makes a great deal of audio noise in transmit mode. The noise is obvious, when all audio input is turned off or unplugged. With the mic gain turned down to zero, or mic unplugged etc., and the RF power output tried at various levels, the noise is heard in a nearby monitoring receiver. (Even XMITR turned right down to its lowest output setting of 5 Watts still produced the noise)

Iahve activated my 10 meter receive only WSPR station as of this morning.

Will try to keep it up 24/7 as much as possible until I get it I can move it to the "server farm" also known as my garage...

Will also try to get a better antenna setup as I am using my only 10 meter antenna right now in a Moxon beam aimed 180degrees from my QTH FM09ap.

I was just wondering what has been done with the data that we've been collecting? I would be interested in seeing what has been learned. It would be interesting to see if the data could be used to model path loss between various parts of the world maybe tying that in with solar activity. I must admit that at the moment I don't know were to start trying to put that kind of a model together, but if anybody has come up with results like that, please share. Maybe people have and I just missed it.
Thanks,

Dave, G0DJA and I had a go with WSPR on 23cm today.

Dave transmitted today & I listened.

We only tried a few transmit cycles. I received good strong traces with little drift and with rx well time-synched.

On 4m, Brian's signals from Liverpool way often show doppler reflections & distortion, but decodes are reliable.

VE5MU has moved from Regina, SK (DO70QK) to Saskatoon, SK DO62QD, also running a new antenna, a large delta Loop approx 350 feet , apex at 4o feet and fed in from one corner with an SGC tuner at the feed point.

Today I received my first SWL rpt by mail from Frank Hunger from Germany.
A nice postcard and a very nice letter with ofcourse the details from his reception report.
Thanks for this one Frank and a qsl card is on the way back to you.

Greetings Johan, PE9DX.

Up to an hour or so ago, reported power on transmissions
of 5 watts or less were understated by 2-3 db. This was caused
by my MFJ tuner reading 2-3 db low in the one watt range.

While MFJ does not spec the accuracy of the wattmeter in the
993B, it is inelegant to show two significant digits when
the measurement accuracy is less than one significant digit.

Thanks for the suggestion of GB3RAL Graham. Unfortunately I can't hear it! I can't hear GB3MCB most of the time either.

GB3ANG 70.020 reads 70.019,89 so 110 Hz low on the dial.
GB3CFG 70.027 reads 70.027,75 so 750 Hz up on the dial.

So no consistent shift and so I don't trust the accuracy of the beacon frequencies.

I'll try 28.028,80 as my dial freq for WSPR today & see if I can spot you & Brian again.

I decided to try something fancier than the Minimalist
sound card interface I described previously.

This hasn't worked so far.

I'm pretty sure the clock is pretty well synchronised and the antenna and transverter are working pretty well. The WSPR software worked fine on 10m with sensible-looking decodes.

The problem may be that my rx frequency is off. I'm having a problem checking this as the only beacon I've heard recently is GB3ANG.

I have two wire antennas pointed in different directions: an inverted V pointed NE/SW and a bob-tail curtain pointed NW/SE. WSPR has been useful in helping me see if the antennas really have any directional characteristics. Indeed, they do. The inverted V gets me into NE Canada and Europe in one direction and SE Asia in the other (from WA state). The bob-tail curtain shows directivity into South America in one direction and Japan/Siberia in the other. State side, both antennas seem to be about equal with, perhaps, the bob-tail curtain being better for Florida.

I picked up a pair of fancy 1/8 inch mono Radio Shack
phone plugs for the latest iteration of my rig interface.
Everything worked normally until Thursday afternoon
when the stations stopped receiving my WSPR signals.
The fishfinder also showed no output. Adjusting audio
and RF gain for full output yielded nothing. But the
radio's microphone got out normally.

Using a Trio TS-440s at 5 watts. The antenna is a Hustler 5BTV vertical ground mounted about 100 feet away from the shack. Quite a number of ground radials but could do with a few more and have run out of junk cable.
Have a little problem keeping the output power at 5 watts, it can vary between 4 and 6 watts between tranmissions, maybe a temperature effect.

This is a comment about the choice of 7.040 as the WSPR frequency on 40 meters. I recently posted a benign comment on the QRP list about openings in propagation based on my spots on the 30 meter band, and received a polite but negative comment from a ham who loves QRP CW on 40 meters. His negative feelings arise not from 30 meters, but from 40M. He points out that 7.040 is still a QRP calling frequency, occupied by CW ops for many years.
