Spectrum Holes Part 1 - 22 March 2008
Spectrum Hole List Part 2 (260-294.975 MHz)
When reporting activity on any of the spectrum hole frequencies on our list, be sure to pass along any info that can help identify the user and frequency usage. Also let me 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 are the highest priority monitoring targets and should be monitored very closely. Any freqs marked with an asterisk should also be high on your target list.
