Dear reader,

This is my second evening on 40 meters WSPR. As I write this, 5 stations are heard in Holstebro, Denmark (JO46gi). It is beginning to get dark, so I expect UK and Eire stations to surface soon.

My antenna is just 10 meters of household electrical cable on the floor (radial), and 10 meters on the roof. Not optimal - but it works for RXing.

I had some problemes when starting in this corner of the radio hobby.

1. What audio device to select?
Having downloaded and installed WSPR 1.12 by K1JT, I could not decide which audio device to select in Setup -> Options. When WSPR started, the command window displayed four lines:

Audio device 0; Microsoft Sound Mapper - Input
Audio device 1; NVIDIA(R) nForce(TM) Audio
Audio device 2; Microsoft Sound Mapper - Output
Audio device 3; NVIDIA(R) nForce(TM) Audio

Selecting device 1 for "Audio In" and device 3 for "Audio Out" worked for me.

2. How to get audio into WSPR
