[Scan-DC] Re: Question re: cell-like antennas on gas meters and such

Ok, I believe I figured out the 170mhz thing..

----begin---

Sample excerpt from NOAA Federal Hydrologic Approval Letter

The Federal Interagency Hydrologic Radio Frequency Coordination Group
has no objections to 3 Rivers Wet Weather request to establish a

170.250 MHz as outlined in your letter....

Also, does anyone have an accurate list of freqs of these and is there
a way to decode them easily (out of curiosity)?
