For each band, only those license classes with privileges on that band are listed. Technician licensees have limited privileges below 30 MHz.

US Amateur Transmitter Power Limits

At all times, transmitter power must be the minimum necessary to carry out the desired communications. Unless otherwise noted, the maximum power output is watts PEP. Novice/Technicians are limited to watts PEP on HF bands. Geographical power restrictions apply to the meter, 70 centimeter, 33 centimeter and 23 centimeter bands.

To operate on or meters, amateurs must first register with the Utilities Technology Council online at https://utc.org/plc-database-amateur-notification-process/. You need only register once for each band.

60 Meters: Five Specific Channels

The FCC has granted hams secondary access on USB only to five discrete kHz-wide channels. Amateurs can not cause inference to and must accept interference from the Primary Government users. The NTIA says that hams planning to operate on 60 meters "must assure that their signal is transmitted on the channel center frequency." This means that amateurs should set their carrier frequency kHz lower than the channel center frequency.

The FCC has allocated MHz to amateur use on a secondary basis. This allocation is only for fixed digital message forwarding systems operated by all licensees except Novices. Amateur operations must not cause interference to, and must accept interference from, primary services in this and adjacent bands. Amateur stations are limited to 50 W PEP output and kHz bandwidth. Automated Maritime Telecommunications Systems (AMTS) stations are the primary occupants in this band. Amateur stations within miles of an AMTS station must notify the station in writing at least 30 days prior to beginning operations. Amateur stations within 50 miles of an AMTS station must get permission in writing from the AMTS station before beginning operations. The FCC requires that amateur operators provide written notification including the station's geographic location to the ARRL for inclusion in a database at least 30 days before beginning operations.

Ham Radio Frequencies
The Playground!

Ah! The ham radio frequencies. This is where exciting things happen for most of us. It's our main playing field and it's huge!

VE2DPE on ham radio frequencies.VE2DPE Ham Radio Operator

Some, like me, also enjoy experimenting with homemade antennas, equipment modification and kits.

But, that's off topic. I have other pages on this site that cover the many other playgrounds of ham radio!

Getting back to amateur radio frequencies


The allocation of frequency bands is coordinated by the member countries of the IARU - International Amateur Radio Union.

  • IARU Region 1 includes:  Europe, Africa, Middle East and Northern Asia.
  • IARU Region 2 includes:  The Americas (North, Central & South)
  • IARU Region 3 includes:  Asia-Pacific.

There are slight differences, between IARU regions, in the allocated ham radio frequencies, and the modes that each will allow.

LF MF & HF
Ham Radio Frequencies

The table below gives a summary of the bands for LF (low frequencies), MF (medium frequencies) and HF (high frequencies).

Ham Radio
Repeater Frequencies

It has recently become easy to keep tabs on repeater frequencies, features and available modes of operation.

The RFinder (RepeaterFinder) Worldwide Repeater Directory is available as an application for mobile devices (iPhone, iPads, Android phones and tablets). It is also available on the Web.

Ham Radio Beacons
A User Guide

Learning how to monitor ham radio beacons is the secret to successful and plentiful DX!

Beacons provide early and measurable indications of propagation conditions.

By being diligent, and patient, you can send out a CQ as soon as you begin to hear a beacon.

In doing so, you will often be the one to start a pileup instead of trying to fight your way in! ;-)

Ham Radio Beacon Frequencies

The Northern California DX Foundation operates eighteen ham radio beacons on five continents which transmit in successive one-minute intervals on , , , and MHz.

The NCDXF beacon call sign and the first dash is sent at Watts. The remaining dashes are sent at 10Watts, 1 Watt and Watts. Very handy info for QRPers!

Almost all ten meter beacons transmit between MHz and MHz. You will find a comprehensive list here.

Six meter beacons are mostly found between MHz and MHz, with a concentration between MHz and MHz.

One example is W4CLM/B transmitting 30 Watts continuously into a vertical on MHz (+/-) from location EM74 (Atlanta, GA.).

Beacon Monitoring Antennas

Ideally, you should use an omnidirectional antenna on every ham radio band that you want to monitor! I did say ideally! ;-)

In practice, I suggest that you use some form of omnidirectional, multi-band antenna to monitor HF beacons.

I use my meter inverted "L" as a general purpose multi-band antenna. It's not ideal but its the best I have available.

If you use a directional antenna (i.e. multi-element beam) to monitor the beacons , you will only effectively hear the beacons in the direction toward which your beam is pointing. But, that may be just be what you want, anyway.

Beacon Monitoring Software

Monitoring ham radio beacons manually is tiresome, to say the least. Many software programs have been written, for many different personal computer operating systems.

Using software to control your receiver automates the beacon scanning process and frees you to work on (or play with) something else in the meantime.

The Northern California DX Foundation lists a number of programs that have been verified to work as advertised. You will find the list here.

Other Means Of Monitoring
Ham Radio Frequencies

Many hams monitor their local packet DX Cluster node for DX activity and to decide whether to join in the action or not. Others log in DX nets to get a chance of making brief contacts with participating DX stations.

Obviously, monitoring beacons to alert you of band openings will let you become the action that will later be reported on DX cluster nodes!

Non - Ham Radio Beacons

The standard time stations (below) will give you some indication of propagation conditions on ham radio frequencies. But, keep in mind that they transmit at much higher power levels than the ham radio maximum legal power limit!

In other words, when you can receive a signal from CHU or WWV, it does not necessarily mean that the closest amateur radio band is usable by most ham radio operators.

The CHU Canada time signal transmitting station is located 15 km southwest of Ottawa, Ontario, Canada at 45º 17' 47" N, 75º 45' 22" W. Main transmitter powers are 3 kW at and 14 kHz, and 10 kW at kHz. Individual vertical antennas are used for each frequency.

WWV transmits from Fort Collins, Colorado, and WWVH, from Kauai, Hawaii, on , , 10, 15 and 20 MHz.

Other Information
Sources

To complement your monitoring of ham radio beacons, you can listen to WWV broadcast the latest solar-flux index at 18 minutes past the hour, and at 45 minutes past the hour on WWVH.Generally speaking, the higher the solar-flux index, the higher the MUF.

PSK31
Ham Radio Frequencies

One of the most frequented PSK31 frequencies is kHz. However, you will also find PSK31 activity on the following HF ham radio frequencies:

  • MHz
  • MHz
  • MHz
  • MHz
  • MHz

Please note that the frequency displayed on your transceiver is the suppressed carrier frequency!

BPSK - binary phase-shift keying - is the most popular mode of PSK

Which Sideband To Use For PSK31?

It will not matter which sideband you use to work BPSK31 signals. You can work any BPSK signal that the PSK31 software displays in the "waterfall" window.

Do keep in mind that your transceiver sideband filter will pass all signals within 2 to (even up to 3 kHz in some cases) above (if in USB) or below (if in LSB) the displayed frequency on your transceiver.

Note that some 90 PSK31 signals can squeeze in 3 kHz, side-by-side! If a signal within the passband is very strong, your transceiver AGC will reduce the RF gain effectively wiping out the weak PSK31 signals within the passband.

QRM On PSK31 Ham Radio Frequencies

There are two solutions to interfering strong signals nearby.

  • Install and switch-in a narrow IF filter if your transceiver is designed to accept one or more.
  • Use a SDR receiver or transceiver! You can really narrow the receiving the passband at will with a SDR. It's like putting up a brick wall between you and the nearby QRM! :-)

More About PSK31

For an in-depth coverage of BPSK31 and all other digital modes in use by ham radio operators on HF, I recommend ARRL's HF Digital Handbook.

See PSK31 software here.

Amateur radio frequency allocations

Amateur radio frequency allocation is done by national telecommunication authorities. Globally, the International Telecommunication Union (ITU) oversees how much radio spectrum is set aside for amateur radio transmissions. Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license.

Radio amateurs use a variety of transmission modes, including Morse code, radioteletype, data, and voice. Specific frequency allocations vary from country to country and between ITU regions as specified in the current ITU HF frequency allocations for amateur radio.[1] The list of frequency ranges is called a band allocation, which may be set by international agreements, and national regulations. The modes and types of allocations within each frequency band is called a bandplan; it may be determined by regulation, but most typically is set by agreements between amateur radio operators.

National authorities regulate amateur usage of radio bands. Some bands may not be available or may have restrictions on usage in certain countries or regions. International agreements assign amateur radio bands which differ by region.[2][3]

Band characteristics[edit]

Low frequency[edit]

See also: Low frequency

Medium frequency[edit]

See also: Medium frequency

  • &#;meters &#; –&#;kHz &#; just below the commercial AM broadcast band and the maritime radio band.
  • meters &#; &#;&#;kHz (&#;MHz) &#; just above the commercial AM broadcast band. This band is often taken up as a technical challenge, since long distance (DX) propagation tends to be more difficult due to higher D&#;layer ionospheric absorption. Long distance propagation tends to occur only at night, and the band can be notoriously noisy particularly in the summer months. &#;meters is also known as the "top band". Allocations in this band vary widely from country to country.

High frequency[edit]

See also: High frequency

  • 80&#;meters &#; &#;&#;MHz (&#;&#;kHz) &#; Best at night, with significant daytime signal absorption. Works best in winter due to atmospheric noise in summer. Only countries in the Americas and few others have access to all of this band, in other parts of the world amateurs are limited to the bottom &#;kHz (or less). In the US and Canada the upper end of the sub-band from &#;&#;MHz, permits use of single-sideband voice as well as amplitude modulation, voice; this sub-band is often referred to as "75&#;meters".
  • 60&#;meters &#; 5&#;MHz region &#; A relatively new allocation and originally only available in a small number of countries such as the United States, United Kingdom, Ireland, Norway, Denmark, and Iceland, but now continuing to expand. In most (but not all) countries, the allocation is channelized and may require special application. Five channels are available in the US, centered on , , , , and &#;MHz; since most SSB radios display the (suppressed) carrier frequency, in USB mode the dial frequencies would all be &#;kHz lower. Voice operation is generally in upper sideband mode and in the USA it is mandatory. The ITU World Radiocommunications Conference (WRC) approved a Worldwide Frequency Allocation of &#;&#;MHz to the Amateur Service on a secondary basis. The allocation limits amateur stations to 15&#;Watts effective isotropic radiated power (EIRP); however some locations will be permitted up to 25&#;W EIRP.
  • 40&#;meters &#; &#;&#;MHz &#; Considered the most reliable all-season DX band. Popular for DX at night, 40 meters is also reliable for medium distance (&#;km; miles) contacts during the day. Much of this band was shared with broadcasters, and in most countries the bottom &#;kHz or &#;kHz are available to amateurs. However, due to the high cost of running high-power commercial broadcasting facilities, decreased listenership, and increasing competition from Internet-based international broadcast services, many "short wave" services are being shut down, leaving the 40&#;meter band free of other users for amateur radio use.
  • 30&#;meters &#; &#;&#;MHz &#; a very narrow band, which is shared with non-amateur services. It is recommended that only Morse Code and data transmissions be used here, and in some countries amateur voice transmission is actually prohibited. For example, in the US, data, RTTY and CW are the only modes allowed at a maximum &#;W peak envelope power (PEP) output. Not released for amateur use in a small number of countries. Due to its location in the centre of the shortwave spectrum, this band provides significant opportunities for long-distance communication at all points of the solar cycle. 30&#;meters is a WARC band. "WARC" bands are so called due to the special World Administrative Radio Conference allocation of these newer bands to amateur radio use. Amateur radio contests are not run on the WARC bands.
  • 20&#;meters &#; &#;&#;MHz &#; Considered the most popular DX band; usually most popular during daytime. QRP operators recognize &#;MHz as their primary calling frequency in that band. Users of the PSK31 data mode tend to congregate around &#;MHz. Analog SSTV activity centers on &#;MHz.
  • 17&#;meters &#; &#;&#;MHz &#; Similar to 20&#;meters, but more sensitive to solar propagation minima and maxima. 17&#;meters is a WARC band.
  • 15&#;meters &#; 21&#;&#;MHz &#; Most useful during solar maximum, and generally a daytime band. Daytime Sporadic E propagation (&#;km; miles) occasionally occurs on this band.
  • 12&#;meters &#; &#;&#;MHz &#; Mostly useful during daytime, but opens up for DX activity at night during solar maximum. 12&#;meters is one of the WARC bands. Propagates via Sporadic E and by F2 propagation.
  • 10&#;meters &#; 28&#;&#;MHz &#; Best long distance (e.g., across oceans) activity is during solar maximum; during periods of moderate solar activity the best activity is found at low latitudes. The band offers useful short to medium range groundwave propagation, day or night. Due to Sporadic&#;E propagation during the late spring and most of the summer, regardless of sunspot numbers, afternoon short band openings into small geographic areas of up to &#;km; miles occur. Sporadic&#;E is caused by areas of intense ionization in the E&#;layer of the ionosphere. The causes of Sporadic E are not fully understood, but these "clouds" of ionization can provide short-term propagation from 17&#;meters all the way up to occasional 2&#;meter openings. FM operations are normally found at the high end of the band (Also repeaters are in the &#;&#;MHz segment in many countries).

Very high frequencies and ultra high frequencies[edit]

Frequencies above 30&#;MHz are referred to as Very High Frequency (VHF) region and those above &#;MHz are called Ultra High Frequency (UHF). The allocated bands for amateurs are many megahertz wide, allowing for high-fidelity audio transmission modes (FM) and very fast data transmission modes that are unfeasible for the kilohertz-wide allocations in the HF bands.

While "line of sight" propagation is a primary factor for range calculation, much of the interest in the bands above HF comes from use of other propagation modes. A signal transmitted on VHF from a hand-held portable will typically travel about 5&#;10&#;km (3 to 6 miles) depending on terrain. With a low power home station and a simple antenna, range would be around 50&#;km (30 miles).

With a large antenna system like a long yagi, and higher power (typically &#;Watts or more) contacts of around &#;km ( miles) using the Morse code (CW) and single-sideband (SSB) modes are common. Ham operators seek to exploit the limits of the frequencies usual characteristics looking to learn, understand, and experiment with the possibilities of these enhanced propagation modes.

Sporadic band openings[edit]

Occasionally, several different ionospheric conditions allow signals to travel beyond the ordinary line-of-sight limits. Some amateurs on VHF seek to take advantage of "band openings" where natural occurrences in the atmosphere and ionosphere extend radio transmission distances well over their normal range. Many hams listen for hours hoping to take advantage of these occasional extended propagation "openings".

The ionospheric conditions are called Sporadic E and Anomalous enhancement. Less frequently used anomalous modes are tropospheric scatter and Aurora Borealis (Northern Lights). When overhead, moon bounce and satellite relay are also possible.

Sporadic E[edit]

Some openings are caused by islands of intense ionization of the upper atmosphere known as the E Layer ionosphere. These islands of intense ionization are called "Sporadic&#;E" and result in erratic but often strong propagation characteristics on the "low band" VHF radio frequencies.

The 6&#;meter amateur band falls into this category, often called "The Magic Band", 6&#;meters will often "open up" from one small area into another small geographic area –&#;km ( to miles) away during the spring and early summer months. This phenomenon occurs during the fall months, although not as often.

Tropospheric refraction[edit]

Band openings are sometimes caused by a weather phenomenon known as a tropospheric "inversion", where a stagnant high pressure area causes alternating stratified layers of warm and cold air generally trapping the colder air beneath. This may make for smoggy/foggy days but it also causes VHF/UHF radio transmissions to travel or duct along the boundaries of these warm/cold atmospheric layers. Radio signals have been known to travel hundreds, even thousands of kilometers (miles) due to these unique weather conditions.

For example: The longest distance reported contact due to tropospheric refraction on 2&#;meters is &#;km ( miles) between Hawaii and a ship south of Mexico. There were reports of the reception of one way signals from Réunion to Western Australia, a distance of more than &#;km ( miles).[4]

"Tropo-scatter" happens when water droplets and dust particles refract a VHF/UHF signal over the horizon. Using relatively high power and a high gain antenna, this propagation will give marginal enhanced over-the-horizon VHF and UHF communications up to several hundred kilometers (miles). During the s commercial "scatter site" operators using huge parabolic antennas and high power used this mode successfully for telephone communications services into remote Alaska and Canadian northern communities.

Satellite, buried fiber optic, and terrestrial microwave access have relegated commercial use of tropo-scatter to the history books. Because of high cost and complexity this mode is usually out of reach for the average amateur radio operator.

Anomalous trans-equatorial enhancement[edit]

F2 and TE band openings from other ionospheric reflection/refraction modes, or sky-wave propagation as it is known can also occasionally occur on the low band VHF frequencies of 6 or 4&#;meters, and very rarely on 2&#;meters (high band VHF) during extreme peaks in the 11&#;year sunspot cycle.

The longest terrestrial contact ever reported on 2&#;meters (&#;MHz) was between a station in Italy and a station in South Africa, a distance of &#;km ( miles), using anomalous enhancement (TE) of the ionosphere over the geomagnetic equator. This enhancement is known as TE, or trans-equatorial propagation and (usually) occurs at latitudes –&#;km ( to miles) within either side of the equator.[5]

Auroral backscatter[edit]

Aurora: An intense solar storm causing aurora borealis (Northern Lights) will also provide occasional HF-low band 6 meter VHF propagation enhancement. Aurora only occasionally affects 2&#;meters. Signals are often distorted and on the lower frequencies give a curious "watery sound" to normally propagated HF signals. Peak signals usually come from the north, even though the station you are talking to is east or west of you. Most noticeable in the northern latitudes above 45&#;degrees.

Moon Bounce (Earth-Moon-Earth)[edit]

Amateurs do successfully communicate by bouncing their signals off the surface of the moon, called Earth-Moon-Earth (EME) transmission.

The mode requires moderately high power (more than &#;Watts) and a fairly large, high-gain antenna because round-trip path loss is on the order of &#;dB for 70&#;cm signals. Return signals are weak and distorted because of the relative velocities of the transmitting station, moon and the receiving station. The moon's surface is also very rocky and irregular.

Because of the weak, distorted return signals, Moon bounce communications use digital modes. For example, old-fashioned Morse code or modern JT65, designed for working with weak signals.

Satellite relay[edit]

Satellite relay is not really a propagation mode, but rather an active repeater system. Satellites have been highly successful in providing VHF/UHF/SHF users "propagation" beyond the horizon.

Amateurs have sponsored the launch of dozens of communications satellites since the s. These satellites are usually known as OSCARs (Orbiting Satellite Carrying Amateur Radio). Also, the ISS has amateur radio repeaters and radio location services on board.

Amateur television[edit]

Main article: Amateur television

Amateur television (ATV) is the hobby of transmitting broadcast- compatible video and audio by amateur radio. It also includes the study and building of such transmitters and receivers and the propagation between these two.

In NTSC countries, ATV operation requires the ability to use a 6&#;MHz wide channel. All bands at VHF or lower are less than 6&#;MHz wide, so ATV operation is confined to UHF and up. Bandwidth requirements will vary from this for PAL and SECAM transmissions.

ATV operation in the 70&#;cm band is particularly popular, because the signals can be received on any cable-ready television. Operation in the 33&#;cm and 23&#;cm bands is easily augmented by the availability of various varieties of consumer-grade wireless video devices that exist and operate in unlicensed frequencies coincident to these bands.

Repeater ATV operation requires specially-equipped repeaters.

See also slow-scan television.

Below the MW broadcast band[edit]

See also kHz, meter band and meter band

Historically, amateur stations have rarely been allowed to operate on frequencies lower than the medium-wavebroadcast band, but in recent times, as the historic users of these low frequencies have been vacating the spectrum, limited space has opened up to allow for new amateur radio allocations and special experimental operations.

Since parts of the &#;kHz band are no longer used for regular maritime communications[citation needed], some countries permit amateur radio radiotelegraph operations in that band. Many countries, however, continue to restrict these frequencies which were historically reserved for maritime and aviation distress calls.[6]

The &#;meter band is available for use in several countries, and the World Radiocommunication Conference (WRC) made it a worldwide amateur allocation. Before the introduction of the &#;meter band in the UK in , operation on the even lower frequency of 73&#;kHz had been allowed between and

Special note on the channeled 60&#;meter band[edit]

(ARRL Meter Operations [1]

The National Telecommunications and Information Administration (NTIA) is the primary user of the 60&#;meter band. Effective 5 March the FCC has permitted CW, USB, and certain digital modes on these frequencies by amateurs on a secondary basis.

The FCC Report and Order permits the use of digital modes that comply with emission designator 60H0J2B, which includes PSK31 as well as any RTTY signal with a bandwidth of less than 60&#;Hz. The Report and Order also allows the use of modes that comply with emission designator 2K80J2D, which includes any digital mode with a bandwidth of &#;kHz or less whose technical characteristics have been documented publicly, per Part (4) of the FCC Rules. Such modes would include PACTOR I, II or III, baud packet, MFSK, MT63, Contestia, Olivia, DominoEX and others.

On 60 meters hams are restricted to only one signal per channel and automatic operation is not permitted. In addition, the FCC continues to require that all digital transmissions be centered on the channel-center frequencies, which the Report and Order defines as being &#;kHz above the suppressed carrier frequency of a transceiver operated in the Upper Sideband (USB) mode. As amateur radio equipment displays the carrier frequency, it is important for operators to understand correct frequency calculations for digital "sound-card" modes to ensure compliance with the channel-center requirement.

The ARRL has a detailed band plan for US hams showing allocations within each band.

RAC has a chart showing the frequencies available to amateurs in Canada.

ITU Region 3[edit]

ITU region 3 consists of Australia, Indonesia, Japan, New Zealand, the South Pacific, and Asia south of Siberia. The IARU frequency allocations for hams in ITU Region 3[9] are:

Bands above &#;MHz: Societies should consult with the amateur satellite community for proposed satellite operating frequencies before deciding local bandplans above &#;MHz.

Not all Member Unions follow this plan. As an example, the ACMA does not allow Australian Amateurs to use &#;MHz to &#;MHz and &#;MHz to &#;MHz, allocating this region to Emergency and Ambulatory services (Allocations can be found conducting a search of the ACMA Radcomms register [2]. )

The Wireless Institute of Australia has charts for Amateur frequencies for Australia.

The New Zealand Association of Radio Transmitters (NZART) has charts for Amateur frequencies for New Zealand.

The Japanese have charts for Amateur frequencies in Japan[10]

Space operations[edit]

See also: amateur radio satellite

Radio amateurs may engage in satellite and space craft communications; however, the frequencies allowed for such activities are allocated separately from more general use radio amateur bands.

Under the International Telecommunication Union's rules, all amateur radio operations may only occur within 50 kilometres (31&#;mi) of the Earth's surface. As such, the Amateur Radio Service is not permitted to engage in satellite operations; however, a sister radio service, called the Amateur Satellite Service, exists which allows satellite operations for the same purposes as the Amateur Radio Service.

In most countries, an amateur radio license conveys operating privileges in both services, and in practice, the legal distinction between the two services is transparent to the average licensee. The primary reason the two services are separate is to limit the frequencies available for satellite operations. Due to the shared nature of the amateur radio allocations internationally, and the nature of satellites to roam worldwide, the ITU does not consider all amateur radio bands appropriate for satellite operations. Being separate from the Amateur Radio Service, the Amateur Satellite Service receives its own frequency allocations. All the allocations are within amateur radio bands, and with one exception, the allocations are the same in all three ITU regions.

Some of the allocations are limited by the ITU in what direction transmissions may be sent (EG: "Earth-to-space" or up-links only). All amateur satellite operations occur within the allocations tabled below, except for AO-7, which has an up-link from &#;MHz to &#;MHz.
