Well, I have them here somewhere but they will be over five years old and I don't know if they changed since then. I did a search on the FCC website and found 13 low power frequencies in the 219Mhz band and wonder if they didn't go up there. I remember they used to be in the 161 range though. All you could hear was a tone, unless something started moving. My list had the frequency of each station so that would really be helpful and I'm hoping I didn't accidentally toss them out... The ones I had were for the U.W. stations, which are what you want. Meanwhile SOMEONE out there should still have that list! I'm interested in reacquiring it too. |

Just a note to keep everyone on track. The U of W uses FCC licensed frequencies and the USGS uses Federal frequencies. The frequencies above 162 mhz to 174 Mhz are USGS frequencies. Maybe one list of all such frequencies is needed. |

| Post subject: | Seismo freqs (this is a 1996 list) |
Note that one freq had a number of tones associated specifically with the seismograph at a specific station location. 162.125 GSM , FMW , GHW , LMW 162.175 RMW 162.200 GMW, RVC, MEW, CPW, RER, BLN, STW Also heard but not identified were: 163.605 164.845 and 165.810 Rem: This is 1996 info and I haven't listened to them since then. I believe each station transmits 100mw and has a horizontally polarized beam so you need to be almost line of sight to hear it. Let me know if anyone has info more current than this. |

| Post subject: | More sesimic stuff |
I just looked up the station number that I posted and I only see two of them in place now. In addition, I read an article where the stations they are using at St. Helens are combination GPS, seismic, laser-height sensing combinations with what appeared to be a satellite uplink on them. There was no specific information regarding satellite uplink but the picture led me to believe that they were either doing that or beaming out up in the Ghz range. Maybe 2.4Ghz. So I think our days of monitoring that stuff are gone. Anyone else have better info? |
