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. This group does realize the importance of
weak signal operation and the works to protect our use of it. Band plans,
as they pertain to Colorado, can be found at their site:
