According to something you said in your interface PDF,
-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).

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 removed from old 56k PCI telephone modems, with some
pads and pots. I'll check out your interface

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

WSPR is not at all demanding of computers or operating system, but it
helps to have a good sound card
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.

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 tens
of thousands of data points for both the station under evaluation and
the gold standard

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 long term project,
I.E. you need to set up and monitor for hours, days, even weeks to

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.

The most important thing to remember is that you absolutely need a
second station as a partner in order to eliminate propagation effects.
Otherwise you are not comparing two antennas, but just sampling prop.

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. :-)

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 in the
basement. I have on occasion run 100 watts on 160 but if you need to do
that because of

Also, use a good A/D converter to get the RX audio into your computer.
