[Lowfer] Laptop problem with ARGO

Turn down the volume in Windows. Look in the control panel of Windows for
the multimedia settings or sound settings which ever it shows in your system
or if you have a speaker icon in the bottom right next to the clock, double
click it to get into the sound window.

6" of new snow on the ground and heavy snow coming down right now. Going to
sleep now. Good luck.

Subject: [Lowfer] Laptop problem with ARGO

I've been testing my wife's 800mhz Compaq laptop computer in the shack for
planned use in the car with ARGO to allow long distance signal mapping of
WA. I was able to  make a great copy of WA a month ago at 120 mi in the
mountains so it's a given that this will work with my 'Wm' FM modulation.

The problem is that Jay's 115mi QRSS signal here in the shack, is strong,
but blurred in the horizontal direction to the extent that it's difficult to
make out the call. The sensitivity setting doesn't seem to help. My regular
computer in the shack does a good job with Jay's signal and produces nice
dogbones and plenty of intercharacter spacing. Another unusual
characteristic on the laptop is the way the signal strength meter on the
left side behaves relative to the other computer. It jumps up and down about
half of the full scale range on normal noise in the signal and is very
sensitive to the volume control setting on the R-75. The other computer
produces a small fraction of the full scale range from noise and is not very
sensitive to the volume control setting. Changing the microphone gain
setting in the Calibration section does not improve the situation.

Any suggestions?
