Channel search results differ between FCC, REC and RFree
I conducted a channel search at my proposed location ( 39.456874, 94.237864 ). REC says 105.7 is fully spaced and available, however it does offer a note about spacing from a third adjacent channel. The FCC search and RFree searchs did not show 105.7 as an available frequency at this location.
What would cause this discrepancy? Is the 3rd adjacent channel spacing the issue?
