[Lowfer] Laptop problem with ARGO

[Bill Ashlock]

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?
