Band Plans and How they Work
If you who do not understand band plans, in particular the 2 meter band plan, try reading Bob’s article Choose Your 2M Frequency Wisely by Bob Witte K0NR, An explanation of the 2M band plan (Colorado emphasis) click to read!
The Colorado Council of Amateur Radio Clubs is the official source of band plans within the State of Colorado. Click on their Coordination tab to see the Colorado Band Plans. This group does realize the importance of weak signal operation and the works to protect our use of it.
