Anyone doing any Seismic Monitoring?

Is anyone else monitoring any of the USGS seismograph telemetry signals
in the 162-174 Mhz, 216-220 Mhz, or the 406-420 Mhz bands?

I use a homebrew demodulator to decode the telemetry (non-encrypted for the
ECPA fans) and feed the +/- 5vdc signal to an A/D card in a 286 computer.
The seismograms are displayed real-time and interesting events saved to a
data file.

I'm looking to find some other demodulator circuit designs...
