147.2100 did not return any results. You would do an FCC search on the name or the freq. It's only going to tell you who is licensed and where the transmitter is. No way to know if its a base or mobile or where mobiles are

Even with a valid FCC license, you would not be allowed to jump on any freq and transmit other than the freqs allocated for Amateur radio.
If your going to use the fcc files in dsdplus make sure you adjust the miles from 99 to something lower. Pointless to see all users licensed to a freq up to 100 miles away when most likely you only picking up whats in your general area. Make sure your gps lat/lon is correct.
