Has anyone else heard that beeping and clicking noise on 171.850 mhz? My guess is that it's some kind of sattilitte but maybe some of you may know what it is. I think I have also heard it on 171.925 mhz.

The Virginia Backbone Network carries rainguage and stream data from node to node via microwave and vhf radio links, this system also can carry voice communications from EOC to EOC and to the National Weather Service, Hospitals, etc. All transmissions are controlled via the Virginia State Police Headquarters & VA-EOC.
Roll calls and system maintenance can sometimes be heard daily.


Its primary use is called IFLOWS...its constantly transmitts data from rain gauges and stream guages to the weather service and emergency managers in each county.
