User:Ninly/BandPlans

Because I recognize that a great deal of tedious work went into compiling and tabulating band plan data for several of the amateur radio bands, I'm copying all of that content to this page in case it should be needed for subsequent article revisions. That said, I believe (and have the support of at least one WP:HAM member) that band plans are inappropriate to the wiki because
 * 1) they are voluntary,
 * 2) they are regional, and (perhaps most importantly)
 * 3) Wikipedia is not a guide book.

I hope making these changes won't ruffle too many feathers. If you'd like to discuss them, please do so at the WikiProject talk page.

US Band Plan
By "Gentlemen's agreement", US amateurs voluntarily limit their 160 meter emissions according to the following suggested bandplan:

70 cm
Below is the ARRL US band plan for the 70 cm band, although many local variations exist:

It is common to find repeater inputs and outputs from 438 to 450 MHz, as sanctioned by ARRL-approved frequency coordinating groups such as Northern Amateur Relay Council of California. The local band plan takes precedence over the ARRL band plan.

33 cm
While the national band plan as well as many State band plans call for a -12 MHz split for FM repeaters, an increasing number of States are changing their band plans to reflect the growing number of FM repeaters using -25 MHz splits. Many amateurs feel that eventually the -25 MHz split will become commonplace and all State and national band plans will adopt it.

Below is an example of a more modern 33 centimeter band plan that allocates a -25 MHz repeater split while also grandfathering existing repeaters with a -12 MHz split. This band plan is roughly based on the one developed by the New England Spectrum Management Council.

23 cm
Below is the ARRL US band plan for the 23cm band:

2 m
Below is a common band plan for 2 meters. Note that in some areas (generally whole states) the channel spacing is 20 kHz. Some areas use 15kHz spacing.

Please note, this is the band plan for the USA.

In the UK, the band extends from 144 MHz to 146 MHz.

To summarize:
 * 144.000 to 144.400 narrowband modes.
 * 144.500 to 145.000 is an "all mode" section.
 * 145.000 to 145.200 are VHF repeater inputs.
 * 145.200 to 145.600 are Simplex channels (12.5kHz spacing).
 * 145.600 to 145.800 are the repeater outputs.

Space communications are above 145.800 to the band edge.

1.25 m
Below is an example of a band plan for the 1.25 meter band.

Frequencies of Note

 * CW and SSB calling frequency is 222.100 MHz.
 * FM simplex calling frequency is 223.500 MHz.

Band Plan (Canada)
Industry Canada has officially abolished the use of 220–222 MHz for amateur use, effective January 2006. This leaves 3 MHz of usable spectrum in the 222–225 MHz range.
