I seek a web site where I can find the location of ADS ground stations. The FAA site that has a map showing them does not work 80% of the time and if it does, it shows data that is almost one year old. Another forum reported that the FAA announced some new ground stations that came on line but I cannot locate any web site that gives current information.I am nearing a decision to purchase ADS equipment for my plane and want to know what I expect by way of coverage for ADS B FIS data.Thanks for any help.
