Is anyone using WSPR or WSPR-X on 160m? It just caught my attention. Looks like a great tool to see if any DX paths are open, and motivate one to call CQ DX when they are. WSPR home page: http://www.
Mike, I have not yet experimented with WSPR on Topband, but I think if enough stations were activated, it could be a great way to increase the awareness of path openings and propagation information a
WSPR and WSPRnet.org are fantastic tools. Used properly, they make the Reverse Beacon network look like a kids toy. I have used the WSPR system to watch propagation and evaluate both TX and RX antenn
Larry, Do you care to elaborate on the setup and procedure which you are using? Inquiring minds are interested, in particular for Topband. 73 de Milt, N5IA --SNIP-- I have used the WSPR system to wat
Milt, Are you familiar with WSPR, it's setup, operation, and it's relationship to WSPRnet? If not, then details won't help much. In a nutshell, it involves collecting data. Thousands, perhaps even te

Jim, Participation varies. At the moment there are more active WSPR stations on 630 meters than on 160! But as we roll into winter there will more show up. It is important to remember that this is a
Thanks for the input. I have WSPR 2.12 installed and working on 30 meters in RX-only mode. I see it's uploading my spots to wsprnet.org. If all goes well, tonight I'll switch to 160. 73, Mike www.w0b
The other thing to remember is that you need a statistically significant number of data points which will require a minimum of three days/nights to a week of sampling. Yes, I strongly agree with both
How well does WSPR work when the band is full of static crashes? If so, is 100 watts too much with 20 over 9 QRN? Just trying to learn. I have it working both RX and TX (5W) on 30 meters right now. :
Mike, WSPR uses a low baud rate interleving process plus averaging to fight through noisy weak signal condx. The worse thing you can do is run excessive filtering or noise blanking because it can con
Normally, I run 5 or 10 watts TX output on 160 meters depending on the specifics of the particular run. On 30 meters it's kinda dumb to run more than 5 watts out unless your antenna is a light bulb i
Also, use a good A/D converter to get the RX audio into your computer. Several good, inexpensive USB sound cards are listed on my website. Switching from the mic input of my laptop to these units all
Thanks for all the additional advice, Gentlemen. I understand about audio levels, filtering, etc. :-) My sound card (old Creative labs unit, IIRC) interface is just a couple of audio transformers rem
I'm interested! Could I run WSPR with my FT-1000 MP and a computer, if I turn the power down to 5 watts or so? What would I need? Probably want to run Windows 7 PRO? Thanks! Charlie, K4OTV Mike, WSPR
WSPR is not at all demanding of computers or operating system, but it helps to have a good sound card to dig weak signals out the noise. It certainly runs fine on XP and Linux. http://k9yc.com/USB_In
Yesterday I decoded a Chinese station on 30m WSPR, at a level of -28. From http://wsprnet.org/drupal/wsprnet/spots: 2014-09-02 21:34 BZ1UIF 10.140268 -28 0 ND81 5 W0BTU EM37 17566 158 According to so
According to something you said in your interface PDF, the -28 seems to indicate that I already have a decent sound card (among other things.) What do you think? Probably yes, but my testing was JT65
-33 is the lowest I've personally decoded, been decoded, and have seen between others. Currently running WSPR4 in Linux with a Microham MK2R+ (built in USB soundcard). 73 Eric NO3M / WG2XJM On 09/03/
