Band plan

The FCC divides the radio spectrum up into multiple bands for different purposes. (frequency allocation) Each frequency range is allocated to groups of users on either a primary or secondary basis.
Additionally, the amateur bands are further subdivided for specific purposes by mutual agreement. These uses are less formal, more localized, and not always followed strictly.
band plans online[edit]
- US Amateur Radio Band Plan app for Android Written by K4UCF member, KA4SON, this lightweight and free Android app allows for easy access to the band plan, as well as refrences to Part 97. Additional features as well.
- ARRL band plans and frequency allocations
- KG4ZOW made some nice simple band plans
