Updated the US allocation tables to reflect current FCC regulations in effect as of December 15, 2006. Also did some minor editing to help the scaling of the graphs be more accurate.

Can someone add the allocations for Canada, EU, and other areas outside of Region 2?

PSK31[edit]

How about mentioning 7.035 as the PSK31 calling frequency (7.030 in Europe)?

NVIS[edit]

How about a discussion about Near Vertical Incidence Skywave (NVIS) propogation? 40 meters is the highest band that benefits from NVIS.


Region 1[edit]

As of 29 marts 2009 the region 1 bandplan has changed and Digimodes are now allocated from 7040-7060 KHz.

The examples and perspective in this article deal primarily with the northern hemisphere and do not represent a worldwide view of the subject.[edit]

The admonishment at the top of the page is factually incorrect. Amateur radio isn't divided into "northern" and "southern" hemispheres. All three regions include both northern and southern hemispheres.

As it happens, the examples given include IARU region 1 (listed explicitly), IARU Region 2 (US and Canada are shown, but IARU 2 includes South America, most of which is certainly in the southern hemmisphere), and IARU Region 3 (Japan, but IARU 3 also include Australia and New Zealand).

The general admonishment of hemisphere-ism should be removed. — Preceding unsigned comment added by Dcowan38 (talkcontribs) 15:56, 30 November 2013 (UTC)
