My wife K4PRM and our daughter were inspired to WSPR by
Joe's lecture at Georgia Tech last Saturday for the Ham Jam.
This is what I've learned so far, after trying to setup WSPR the wee hours.
As it happens sometimes, the computer does not work for you, rather you work for the computer!
In this case, I am working with:
* Windows 7 on an el-cheapo Lenovo laptop
* Laptop audio provided by the internal Conexant High Definition SmartAudio 221 sound card.
* A Navigator USB rig control connected to the CAT-V port on an Icom 756 ProIII.
* Some resonant wires strung in the trees.
But nothing showed up in the waterfall.
Here is a list of things that I encountered before I could WSPR:
1. I heard that newer Windows platforms may prevent recording audio from an external or streaming source.
2. My details are a bit sketchy, but Leo LaPort talked about how the
RIAA and the DRM crowd may have influenced PC mfg's to prevent users from recording audio streams.
3. I first ran into this problem when trying to record Neal Boortz streaming
from http://wsbradio.com/ with Audacity.
I got "Error opening sound device when recording".
Therefore - if Audacity could not hear Neal Boortz, then WSPR could not hear the Icom radio either.
4. Audacity has some very good help that applies to being able to record streaming audio,
and "hear" WSPR audio when using Win 7 here:
5. My work-around is to use an external sound-card. In my case, I'm using the Navigator USB sound card-to-CAT-V interface.
6. I had to add WSPR to the list of "allowed" programs to punch through the Windows firewall.
7. You'll know this problem when you know you have RF coming into the radio, and the radio
is sending audio to the sound card in your PC, but you don't see much color change in your waterfall display.
