WARC bands#30-meter band plan
{{Short description|Amateur radio frequency bands}}
The World Administrative Radio Conference (WARC) bands are three portions of the shortwave radio spectrum used by licensed and/or certified amateur radio operators. They consist of 30 meters (10.1–10.15 MHz), 17 meters (18.068–18.168 MHz), and 12 meters (24.89–24.99 MHz).U.S. Amateur Frequency Allocations http://www.arrl.org/FandES/field/regulations/allocate.html Accessed 9 September 2008ITU Frequency Allocations http://life.itu.int/radioclub/rr/hfband.htm Accessed 9 September 2008 They were named after the World Administrative Radio Conference, which in 1979 created a worldwide allocation of these bands for amateur use. The bands were opened for use in the early 1980s. Due to their relatively small bandwidth of 100 kHz or less, there is a gentlemen's agreement that the WARC bands may not be used for general contesting. This agreement has been codified in official recommendations, such as the IARU Region 1 HF Manager's Handbook, which states: "Contest activity shall not take place on the 5, 10, 18, and 24 MHz bands."{{Citation |title=IARU Region 1 HF band plan |date=2016-06-01 |url=https://www.iaru-r1.org/wp-content/uploads/2019/08/hf_r1_bandplan.pdf |editor-last=((DK4VW))}}
Non-contesting radio amateurs are recommended to use the contest-free HF bands (30, 17, and 12m) during the largest international contests.{{cite web|title=IARU Region 1 HF Band Plan (August 2011 edition)|url=http://www.iarums-r1.org/iarums/hfplanr1.pdf|work=IARU Region 1 Monitoring System|publisher=IARU|access-date=2 September 2013|page=4|date=August 2011}}

Throughout most of the world, the 30-meter band generally cannot be used for "phone" (voice) communications. SSB may be used during emergencies involving the immediate safety of life and property and only by stations actually involved in the handling of emergency traffic.
However, a part of Region 1 is permitted to use phone at certain times.IARU Region 1 Band Plan http://www.iaru.org/Chapter-5.1.pdf {{Webarchive|url=https://web.archive.org/web/20050514182423/http://www.iaru.org/Chapter-5.1.pdf |date=2005-05-14 }} accessed 5 April 2010 The band segment 10.12 to 10.14 may only be used for SSB transmissions in the area of Africa south of the equator during local daylight hours.

==Australia==
Australia (VK, region 3) has a unique set of privileges on 30 meters which allows voice operation on a section of the band for advanced license holders. The digital segment is 10.13-10.15 MHz. The current band plan has telephony from 10.12–10.135 MHz, with CW only below 10.12. These are WIA {{cite web | url=http://www.wia.org.au/members/bandplans/data/ | title=Band Plan Update }} recommendations only as ACMA does not restrict Australian amateurs' modes within HF allocations beyond requiring less than 8 kHz occupied bandwidth per channel below 28 MHz.
