In the ideal case of course you have just receiver noise as your background noise level. So you adjust your sound card input to give you the magic 0dB on that. During the night the static crash level
I listened again last night Roger between 1920 and 2020z and not a trace of you on the waterfall. SM6BHZ and G7NKS were coming in as normal, though Gus's signal seemed well down on what it was the ni
Thanks for the comments John and others. Firstly of course Jim is VERY strong here, well over s9. I did try putting 30dB of attenuation in but he was still moving the meter... I have not at the momen
I have just been doing some more tests on 30m. Clock errors might well have been part of the problem. Initially on 30m the few decodes I was seeing were showing a DT of over 3s, so I had a play with
OK, I seem to have got WSJT sussed, and it is working. It seems to auto calibrate for the sound card, I have done nothing and the two numbers in the bottom right hand are both close to 1... 192803 14
OK, it looks as if the sound card clock synch error is the problem. As suggested I have been trying recording for the first minute of each period then stopping - by the simple expedient of switching
Not quite Dennis. A WSPR transmission period is 114 secs, starting on each even minute and stopping at 54 seconds after the second minute. These periods are fairly accurately timed. A station transmi
Still not a whisper on the waterfall last night Roger, just the usual two Jims booming in: 194400 7 -28 1.4 64 0 G7NKS IO92 27 195200 10 15 1.2 -53 0 M0BMU IO91 33 195600 9 -9 1.9 70 0 G7NKS IO92 27
Still nothing at all here Roger, there were a couple of very weak broken lines on the waterfall but no copy. I tend to take the dB figures in WSRP with a pinch of salt. Jim, James and Gus are quite s
What actual frequency are you transmitting on Roger? As you might have gathered I do have a bit of a problem calibrating WSPR and decoding.... I am running it now, and Argo, and seeing a moderately s
G7NKS was also on, as you see a bit weaker than Gus but seemed to be sharing the same time slots. (note this is WSJT7 output, which is all that will run on my sound card: Time, Sync, dB, DT, DF, Drif
And maybe if you take the attenuators out again you will reach the dizzy heights of Bracknell.... I did monitor till around 10pm last night but no sign, but the QRN got attrocious and I even lost cop
Well having spent a few days looking at WSPR I would tend to fit best in the 'repetitious rubbish' group.... WSPR is specifically designed for weak signal reception, and there is certainly a case of
I had a quick play with WSJT7. But it looks as if WSPR was an add on to the original program, its implementation is a bit basic and the GUI totally different from the separate WSPR program. 1. The ba
This was where G3YXM's site originally was. You can now find it at http://wireless.org.uk/ I am sure Dave will comment in due course, I would assume all the stuff on the old site is now on the curren
