When reporting activity on any of the spectrum hole frequencies in our list, be sure to pass along any info that can help identify the user and frequency usage. Also let us know if you want your catch listed here and how you want to be identified. This list is valid for ITU Region 2 only (North/Central/South America). Other areas of the world have their own bandplans.
Note: Any frequency below that is bolded should be watched very closely and those marked with an asterick are our highest priority frequency monitoring targets. Our highest priority spectrum monitor list currently consist of the following frequencies (from parts 1, 2 3 and 4): 233.600 252.300 252.600 277.300 293.900 298.200 and 336.700 MHz. If you hear anything on these frequencies below please notify me as soon as possible.
