Kareem,

I and a few other PSN members monitor telemetry from remote sensors using
my demodulator (discriminator) board. See
http://www.seismicnet.com/telebrd.html for more information.The output of
the demod board can drive a drum recorder or A/D card. Currently the *.CNI
and *.CGP event files on my system (http://www.seismicnet.com) come from
remote USGS sensors. At one point I had up to 5 channels recording remote
senors. 

The problem is the USGS is slowly going digital around here (N. California)
 making my board obsolete. My board only works with the analog system
commonly used to send analog data using a phone line or audio RF line. 

Regards,
Larry Cochrane
Redwood City, PSN
