When did WARC bands start?
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….IARU Region 1.

What does WARC bands stand for?
World Administrative Radio Conference
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 (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz) and 12 meters (24.890–24.990 MHz).
What is the power limit on 30 meters?
The FCC sets maximum transmitting power limits (Peak Envelope Power) for each amateur frequency band. The given frequency of 10.140 MHz (wavelength = 300/10.140 = 29.58 m) falls within the 30 meter band. The maximum transmitting power allowed on this band is 200 watts PEP output.
What ham bands are the best?
40 metres – 7.0–7.3 MHz – Considered the most reliable all-season DX band. Popular for DX at night, 40 metres is also reliable for medium distance (1500 km; 1000 miles) contacts during the day. Much of this band was shared with broadcasters, and in most countries the bottom 100 kHz or 200 kHz are available to amateurs.
What is the 160-meter band used for?
160-meter band refers to the band of radio frequencies between 1.8 and 2 MHz, just above the medium wave broadcast band. For many decades the lowest radio frequency band allocated for use by amateur radio, before the adoption, at the beginning of the 21st century in most countries, of the 630- and 2200-meter bands.
Why is contesting not allowed on the WARC bands?
The reason contesting is not allowed on the WARC bands is that contesting takes up considerable bandwidth and these bands have little bandwidth to spare. As such, I warned everyone that only FT8/FT4 is in play on these bands and NOT any other mode. Period. FT8 takes place on only ONE frequency – 10.136 MHz on 30m, for example.

Do you prefer WARC or FT8 for Ham contests?
I have plenty of ham friends that really don’t appreciate the bands being full of signals on a contest weekend. These folks often find refuge in the WARC bands. The idea of just allowing one FT8 frequency (oops, it’s not really one frequency, it is 3 kHz wide) sort of sounds OK.
