The 30 meter band is special in a number of ways. It only allows data modes (so no phone), there's a power limit (200 Watts PEP), and contesting is not allowed.

Propagation is usually good during the day and excellent during the night, so it can be a great band for CW or digital DX contacts.

Refer to FCC Section: [97.305]

An easy way to remember this is that no one under the age of about 30 makes actual phone calls.

The FCC has restricted the 30 meter band to only data transmission modes (such as CW, RTTY and packet), so image transmission is prohibited. Image transmissions are found within phone transmission band segments rather than data. Image transmission is prohibited on the 60 meter band as well, where we are restricted to 5 specific frequency channels for SSB phone communication only.

KJ5EMP Hint: NTSC Fast Scan video runs at 30 frames per second, which you'll want to remember if you take the Extra test. Video is not allowed on 30M (or 60M, same memory trick).

The 60 meter band is a shared frequency range where the government has primary rights and amateur radio is restricted to communicating as a secondary service only on specific channels. This is to keep the possibility of signal interference at a minimum.

You are only allowed to operate in frequency spaces where your operation class allows you to do so. The General class license only allows transmission for voice between 7.175 MHz and 7.300 MHz, it does allow for transmission on that segment for Advanced and Extra class operators tho. 28.000 MHz to 28.025 MHz and 21.275 MHz to 21.300 MHz are both allowed spaces to transmit on with a general class license.

(C). As amateurs, we must always follow the rules of COURTESY. In a case where the Amateur Service has been designated as a secondary user (such as on 30 and 60 m bands) this is even more important. Amateur stations are allowed to use the band ONLY if they do NOT cause harmful interference to primary users. Listen First! If you hear another transmission, do not use that frequency. If you hear a primary user come on to the same frequency that you are working or nearby frequency, immediately move your transmission farther away so that you will not interfere with their signal.

FCC Regulations (§ 97.305(a)) specifically say:

• Except as specified elsewhere in this part, an amateur station may transmit a CW emission on any frequency authorized to the control operator.

Currently, there are no specified exceptions to this rule.

Recalling that a General class operator has full access to the 10-meter band, it follows that a General class operator may therefore transmit CW on the entire band.

Just remember that, as an Amateur, CW is always allowed if you are authorized on that frequency.

General class privileges let us use the ranges of 21.025-21.200 MHz (CW/data) and 21.275-21.450 MHz (phone), so the answer 21300 kHz falls within the phone range of the 15 meter band.

Note: Remember that the 15 meter band actually is located below 15 meters (from λ=300/21.450 MHz =13.98 m to λ=300/21.025 MHz=14.27 m). If you remember this and check the wavelength of the 2 values that are close (18155) and (21300), you will find that (18155) gives a wavelength = 300/18.155 MHz = 16.52m, whereas (21300) gives you a value of wavelength = 300/21.300 = 14.08.

If you estimate 300/15 = 20, you'd have 50% correct. So just remember it's a bit above this number which is 21.

Silly memory aid: 2 x 15 = 30.
21300 is the only answer with the numbers 2 and 30.

Even more silly: Only answer that adds up to 15 2+13

47 CFR 97.205 regulates repeaters generally, it prohibits repeaters on the 28.0-29.5 MHz portion of the 10-meter band.

Hint: 300 ÷ 10 = 30 MHz. The correct answer is the one closest to 30.

The general rule is that if sections of a band are split between voice and data, that the upper frequency end of the band is used for voice and the lower frequency end is used for CW/data.
