There is much to be said pertaining to the expected performance of a PC that is to run WSPR/WSJT7. I have been running both of my Windows PCs (one is a 500 MHz PIII with XP Home, the other a 1 GHz Athlon with Vista Home Basic) for a few days now simultaneously running WSPR on both machines. I am amazed at the difference in captures with the fast PC. Not only do I catch more WSPR beacons, but weaker ones as well. The Vista PC has been capturing beacons at -24, -26...and even -28 dB.

One disadvantage to using the Eee PC as an WSPR station - apart from the flakiness of its Linux OS - is that its power supply is a switched mode wall wart of the worst sort, a wideband noise and wandering warble generator. It's made in China and is rated at 9.15V 2.3A output. I don't suppose it will be easy to find a noise free alternative.

Well, in one sense the 10-meter Special Activity Day was nearly a complete bust; but in other ways I found it quite interesting.

I think we had around 20 active stations, most of the time. Not surprisingly, there was very little propagation of any sort, anywhere in the world. About 700 spots were posted, but most of them were at ground-wave distances under 150 km.

However, VK6POP copied the big 20-Watt signal of T61AA several times at 8913 km, for the DX record. Interestingly, nobody else copied T61AA at any distance.

I am personally interested to know how many people run WSPR on Linux and what Release, lets include WSJT.

1) I run Linux XXXXX but use Windows for WSJT/WSPR

2) I run WSJT on Linux XXXXX

3) I run WSPR on Linux XXXXX

4) I would like to run WSJT and WSPR on Linux

Are you a 1, 2, 3, or 4.
Are the number of replies going to be tiny and insignificant.

I have a sig blasting in here S7 or so, but no decode. I use Spectrum Lab to watch the pass band in real time and the sig appears to be a WSPR sig, and on 20 to 25% TX cycle, it is down low around 3.594022. Anyone copy this sig also?

Can anyone tell me where to find explaination of the reports that are receive when running diagnostics with WSPR ver 1.01 and/or WSJT7.
Specifically:
"RX: 0 114 114"
Also:
"Socket error, Non- fatal" Which comes up regardless of whether the diagnostics are activated.

Hi to all.
I'm now of WSPR software. I installed WSPR 1.0_r1023 but when it try to receive (or transmit), an error occour:

AppName: wspr.exe AppVer: 0.0.0.0 ModName: ntdll.dll
ModVer: 5.1.2600.5512 Offset: 0000108d

and the program closing..... How I can solve this problem?

I'm using Windows XP Pro SP3.

I will usually leave WSPR running in receive mode during the night here on the West Coast on either 80m or 160m.

I've done this for the last couple of nights on both 160 and 80 - there seems to be a pretty stable path on both 160 and 80 between VK7 and W6. Also a path exists in the hours before dawn to Wake Island on 80m. Despite WSPR not decoding or logging any spots, I also leave WSJT7 running in WSPR receive mode - WSJT decoded the signals from WA2YUN on Wake this morning at sign levels between -10 and -14 dB. Very impressive as all of these were with 5 watts on the sending end!

Kicking off my first blog entry with a hello to everyone and let folks know what I am working with.

I'll be setting up for weak modes at KL7AA over the holidays. The station is setup for 10/15/20 meters so far with 40 & 80 soon coming.

Antennae planned are one loop for 40/80m and a BigIR vertical for up to 80. Existing is a Cushcraft 3-element Yagi.

The rig is a Yaesu MK-V FT-1000MP with an ACOM 1.5kw linear. The PC and rig are interfaced with a MicroHAM MKII USB. Overall a sweet setup.

The station is operational on digimodes with HRD/DRM780, MultiPSK, MixW etc.

At this point, I can say that I am COMPLETELY amazed at MEPT_JT, and its capabilities. Today, I received VK6BN's transmissions 3 times...from Australia to Western New York on 30 meters. AWESOME. SIMPLY AWESOME.

playing around with wspr on several systems at the same moment, i found out that there was a difference in time (wspr program) after a few hours.
One clock was about 30 seconds ahead of the other computer.
However i synchronize (ntp) the clocks in windows (every 24 hours).
But that seems not to be enough for some computers, gives a difference of minutes per day!
Timing is very crucial in WSPR , the more your of timing, the less spots you get.

On the web a found a freeware program called 'automachron'.

Hi all,

I´m Ricardo EA1RJ, after some weeks testing with WSPR, i think it´s very funny and i have created my account on WSPRnet.org WEBsite.

i hope to report yours weak signals hi hi.

my working conditions are:

Antenas:
Half Sloper on 160 m.
Half Wave Wire dipole on 80 m
Half Wave Rotatory dipole on 40 m (13 m long shorted with coils)
Non specific antenna for 30 m, testing existing antenas.
HY-GAIN Explorer 14 for 20, 15 and 10 m
Half Wave Rotatory dipole on 12 m
ZX-YAGUI 5 elements for 11 m (5,60 m boom)

Hi,

I am running a wspr station for a couple of weeks now, and 'its fun!'

Station Setup here:
8 meter vertical on a steel grid, atu at the feeding point.
homebrew FD3 (40-80mband)
TS430 modified (so i can use cw if filter (250HZ) in ssb mode).
mfj784b dsp filter tuned at a 225HZ bandwith.
Homebrew interface to cpu with 1:1 transformers, ptt = vox driven.
power meter, calibrated, measuring down to 10mW

This morning a made a 3D snapshot of T61AA's signal on 17m.
Special about it is the crossing carrier, that hops the band in and out over here.

This mode is amazing the way it gets through in an apparently dead or noisy band.

Last night we (Tony VK6HAM and I) were getting good results around the place on 20 metres. We decided to crank down the power - tony was able to get down to 1 watt, I couldn't get below 5. We were still getting into Europe and other places. I think I'll have to learn how to put my auto ATU a bit offside to reduce the effective output.

Today I was getting around in spite of finding my loop antenna had one of its four corners on the ground. It's been a bit windy today.
