CB, License-Free Walkie-Talkie, and SRD Systems in Pacific Island Countries


—Small radio waves open to island life—

When talking about radio systems in Pacific Island countries, the conversation often turns to whether walkie-talkies brought from abroad can be used.

However, that is not what I want to look at in this article.

How is small-scale radio communication, which people living in those countries can use for work, local contact, vehicles, daily life, and emergencies, institutionalized?

There is the Citizen Band (CB) where people talk directly to each other. There are portable walkie-talkies. Alongside them, car keys, alarms, tire sensors, toys, and telemetry equipment are sending out short-range radio waves.

When tracking these devices from a regulatory perspective, different approaches become apparent for each country, such as Citizen Band Radio Service (CBRS), General User Radio Licence (GURL), Short Range Devices (SRD), and Low Interference Potential Devices (LIPD).

In this article, I will look specifically at frequencies, number of channels, channel spacing, modes, maximum output, repeaters, and special channels for emergencies and calling as much as possible.

The following is based on official documents obtained and confirmed as of August 19, 2026. For materials where the original source cannot currently be obtained, that fact is noted in the text or in the footnotes. I have not attempted to infer or supplement the content of original sources based solely on search results, old URLs, or secondary materials.


What is the difference between CB, walkie-talkies, and SRD?

CB is a radio service for citizens whose primary purpose is direct communication between people.

In the 27 MHz band, which has been used for a long time, AM, Double Sideband (DSB), and Single Sideband (SSB) are used. On the other hand, UHF CB in the 476–477 MHz band is also prominent in the Pacific region.

There are also differences in the mechanisms referred to as "license-free."

There are systems where each individual user applies for a radio station license, and there are systems where the regulatory authority grants a blanket permit to all users who meet certain technical conditions.

The GURL used in Vanuatu is the latter.

Even if the user does not apply for a license for each individual unit, they operate in accordance with the frequencies, output, and radio emission types specified in the GURL. Therefore, "individual license not required" and "no conditions of use" have different meanings.

SRD is even broader.

Remote Keyless Entry systems, Tire Pressure Monitoring Systems (TPMS), alarms, sensors, toys, RFID, and Bluetooth also fall into the world of SRD.

If CB is "radio waves for people to talk," then SRD also includes "radio waves for machines to talk."


27 MHz, 245 MHz, and 477 MHz are prominent in the Pacific

Looking at the materials from each country, several frequency bands stand out for CB and personal radio.

One is the 27 MHz CB, centered around 26.965–27.405 MHz.

The 40-channel, 10 kHz spacing configuration is well-known globally and can be confirmed in 2012 Vanuatu documents and the Samoa National Frequency Table. [1][2]

The other is the 476–477 MHz band.

In Vanuatu, an 80-channel UHF CB is mentioned in official documents, and in Samoa, 476.400–477.425 MHz is listed as UHF CBRS in the National Frequency Table. [1][2]

And a slightly unique one is around 245 MHz.

In Thailand, the National Broadcasting and Telecommunications Commission (NBTC) still regulates a 245–247 MHz citizens band and has published a band plan with 160 channels at 12.5 kHz intervals. [3]

Regarding Tonga, the consultation draft of the Tonga National Spectrum Plan 2021, which was available on the government website in 2021, listed a VHF CB with 80 channels at 12.5 kHz intervals from 244.9875 to 246 MHz.

However, this official Tongan PDF currently returns a 404 error, and the original text could not be re-acquired this time. Therefore, in this article, it is treated as information from the consultation document published in 2021. [4]


CB has channels designated for "emergency use".

In the US 27 MHz CB, ch 9, 27.065 MHz, is well-known as a channel for emergency and assistance purposes.

There are channels with similar special roles on the Pacific side as well.

In the 2012 edition of Vanuatu's Radio Apparatus Licence and Spectrum Licence (Fees) Regulation, Schedule IV, ch 9 of the 27 MHz CB (27.065 MHz) is designated for emergency communications only. [1]

Furthermore, for UHF CB,

  • ch 5 = 476.525 MHz

  • ch 35 = 477.275 MHz

are designated for emergency communications only. [1]

In other words, within one country's CB system, there are two emergency channel systems: ch 9 on the 27 MHz side and ch 5/35 on the 477 MHz side.

Thailand's 245 MHz CB also has a special channel.

In the current band plan,

  • ch 41 = 245.5000 MHz: Main frequency for disaster prevention, rescue, and emergency/disaster communications

  • ch 1 = 245.0000 MHz: its reserve frequency

is considered to be. [3]

Although the frequencies and channel numbers are different, the concept of "designating a place to gather in an emergency within shared radio for citizens" is common.


Vanuatu—CB opened to citizens via GURL

The Telecommunications, Radiocommunications and Broadcasting Regulator (TRBR) has published a GURL for CB use. [5]

However, one must be careful with Vanuatu's documents regarding differences based on the year.

In the Radiocommunications Regulations (General User Radio Licence for Citizen Band Radio) Notice 2009, which came into effect in 2010, the HF side consists of 40 channels from 26.330 to 26.770 MHz, and the UHF side consists of 40 channels from 476.425 to 477.400 MHz. [5]

On the HF side,

  • SSB: maximum 12 W peak envelope power (PEP)

  • DSB: maximum 4 W carrier power

is the limit.

On the UHF side,

  • Voice: 16K0F3EJN or 16K0G3EJN

  • Selective calling: 16K0F2EJN or 16K0G2EJN

  • maximum 5 W carrier power

is specified. [5]

However, in Schedule IV of 2012, HF CB consists of 40 channels from 26.965 to 27.405 MHz. [1]

Representative channels are

  • ch 1 = 26.965 MHz

  • ch 9 = 27.065 MHz

  • ch 40 = 27.405 MHz

, and ch 9 is reserved for emergency communications.

The output is a maximum of 12 W PEP for SSB and 4 W carrier power for DSB. [1]

The UHF side consists of 80 channels, with a configuration of

  • ch 1 = 476.425 MHz

  • ch 5 = 476.525 MHz

  • ch 35 = 477.275 MHz

  • ch 40 = 477.400 MHz

  • ch 41 = 476.4375 MHz

  • ch 80 = 477.4125 MHz

.

The maximum output is 5 W carrier power, and ch 5 and ch 35 are reserved for emergency communications. [1]

It should be noted here that the frequency configuration differs between the 2010 GURL and the 2012 Schedule IV.

From the public documents confirmed this time, it was not possible to determine the legal succession relationship between the two. Therefore, I will not go so far as to write that "the GURL was amended to this 80-channel system in 2012."

All that is known is that the configuration differs between the two officially published documents.


Vanuatu's SRD—Radio waves for daily life alongside CB

The TRBR's Consumer Champions Handbook is an actual official document that explains the GURL and various consumer radio equipment to residents. [6]

Additionally, the Draft Vanuatu Radio Frequency Spectrum Plan published by the TRBR lists radio-controlled toys, model aircraft, sporting events, road accidents/emergencies, coastal life-saving, natural disaster relief, garage door openers, and security alarms as low-power uses around 26.957–27.283 MHz. [7]

However, as the title suggests, this frequency plan is a **Draft**.

It is best read not as a citation for current regulations, but as a document showing what uses the regulatory authority was considering at that time.

Even so, it is clear that low-power radio waves for citizens are intended for a variety of uses, ranging from conversation to rescue, disaster relief, toys, and household appliances.


Samoa—Viewing CB and SRD in a Single Frequency Table

In the National Frequency Allocation Table 2017 of the Office of the Regulator,

  • HF CBRS: 26.965–27.405 MHz

  • UHF CBRS: 476.400–477.425 MHz

are clearly specified. [2]

While the CB band itself can be confirmed from this national frequency table, within the scope checked this time, it was not possible to determine the maximum CB output, detailed modes, or emergency channel designations.

One must not supplement this with values from neighboring countries.

On the other hand, Samoa's SRD documentation is quite specific.

For non-specific SRD applications, for example,

  • 26.957–27.405 MHz: 10 mW ERP

  • 40.66–40.70 MHz: 10 mW ERP

  • 433.05–434.79 MHz: 10 mW ERP

and others are listed. [2]

There are also multiple low-power segments in the 868 MHz band, with output power divided according to use, such as 25 mW ERP and 100 mW ERP.

Furthermore, regarding automotive applications,

  • Keyless entry: 433 MHz band, ASK or FSK

  • TPMS: 433.92 MHz, 1 mW ERP, FSK

  • Vehicle calling alarms: 458.95 MHz, 10 mW ERP, F1D/FSK

and others are specifically regulated. [2]

For Bluetooth devices, modulation methods such as GFSK, π/4 DQPSK, and 8DPSK are also listed for the 2400–2483.5 MHz band. [2]

In CB, people send voice.

In SRD, car keys and tire sensors send short pieces of information.

The frequency table for Samoa is a document that allows these two to be viewed within the same 'consumer radio' category.


Papua New Guinea—The CBRS band can be confirmed, but details are reserved.

The official technical standards list of the National Information and Communications Technology Authority (NICTA) includes TR603 Citizen Band Radio Service technical specifications. [8]

From the official information currently available,

  • HF CBRS: 26.965–27.405 MHz

  • UHF CBRS: 476.400–477.425 MHz

can be confirmed. [8]

On the other hand, in this re-investigation, the full text of TR603 itself could not be directly obtained.

Therefore, for detailed values such as DSB 4 W, SSB 12 W, and UHF 5 W that were mentioned in the previous manuscript, they will not be adopted as definitive values in this article.

I will also not supplement technical values based on the reason that they are similar to neighboring Australia or Vanuatu.

Papua New Guinea also has a LIPD/SRD system.

In the 2026 draft revision related to the Radiocommunications (Low Interference Potential Devices) Class Licence 2026 published by NICTA, for 26.957–27.283 MHz, the following conditions are indicated:

  • Maximum 1 W EIRP

  • At least 5 kHz away from the center frequency of adjacent CB channels

  • Occupied bandwidth of 10 kHz or less

[9]

Bands such as 433.05–434.79 MHz, 915–928 MHz, and 2400–2483.5 MHz are also listed.

However, this is a public consultation draft for 2026.

NICTA initiated a public consultation on June 25, 2026, and closed it on July 10, but in this verification, it could not be confirmed that this 2026 draft had come into effect through publication in the official gazette. [9][10]

Therefore, it will be treated as the "2026 revised draft" rather than the "current LIPD system."


Tonga—245 MHz CB is interesting, but the original source cannot be re-verified at this time.

The 245 MHz CB in Tonga is very interesting.

The consultation version of the National Frequency Plan, which was published on the Tongan government website in 2021, contained:

  • 244.9875–246 MHz

  • 80 channels

  • 12.5 kHz spacing

VHF CB was listed.

Furthermore, it is said that UHF CB in the 476–477 MHz band was also mentioned.

However, the official government PDF from that time is currently returning a 404 error. [11]

Therefore, in this article, these figures are not asserted as the current system as of 2026.

It goes only as far as stating, "There was such a configuration in the consultation materials published by the government in 2021."

Even so, the 245 MHz frequency itself is worth comparing.

In Thailand, an official 245–247 MHz CB still exists today, operating with 160 channels at 12.5 kHz spacing. [3]

The original first 80 channels are arranged from 245.0000 to 245.9875 MHz.

For this reason, the configuration of 244.9875–246 MHz, 80 channels, and 12.5 kHz spacing that appeared in Tonga's old consultation materials is very similar to Thailand's 245 MHz CB.

However, no original source could be confirmed at this time indicating that the system was directly introduced from Thailand to Tonga.

Therefore, I will not write that they "adopted the Thai system," but will limit the observation to the fact that there is a strong similarity in frequency allocation.

The search index for frequency documents published on the official website of the Autoridade Nacional de Comunicações (National Communications Authority, ANC) of Timor-Leste also contains a description corresponding to VHF CB in the 244.9875–246 MHz range, with 80 channels and 12.5 kHz spacing. [12]

However, the PDF itself could not be directly re-acquired at this time.

While interesting regional similarities can be seen regarding the 245 MHz class VHF CB, further historical document verification is needed regarding its propagation path.


Federated States of Micronesia—CB is used for both personal and business purposes

The Division of Communications of the Federated States of Micronesia publishes an Application for Citizens Band License on its official website. [13]

The application form includes items such as:

  • base

  • mobile

  • handheld

  • business

  • personal

  • call sign

and others.

There is also a section to list family members and employees as users. [13]

What this shows is that the system assumes Citizens Band will be used not only for personal conversations but also for business and communication with employees.

On the other hand, this application form does not list a nationwide common channel table, modes, maximum output, or emergency channels.

Due to the historical relationship with the United States, it is not possible to simply apply the 40 channels or Channel 9 of US CB.


Marshall Islands—CB also appears in local administration

In the FY2024 administrative report of the Ministry of Transportation, Communications & Information Technology of the Marshall Islands, radio licensing operations, including CB, are recorded as achievements. [14]

The report records 68 cases as CB/Radio Licensed, and also includes records of CB inspections and new/renewal operations conducted in outer islands. [14]

Furthermore, the government's strategic plan includes:

  • VHF/CB radio call sign training

  • Domestic VHF/CB Radio Training for Local Governments

are listed. [15]

This is important when considering local usage.

CB not only exists as personal radio equipment, but is also incorporated into communication administration and training for local governments and remote islands.

However, specific CB frequencies, modes, maximum output, and special channels cannot be determined from these administrative reports.


Tuvalu—Inexpensive Citizen Station Licence

Tuvalu's Telecommunications (Radio) Regulations define a citizen station as a formal radio station category. [16]

A citizen station is used for personal communications or the user's own business communications within Tuvalu.

The validity period of a citizen station licence is 12 months.

In the 2008 Revised Edition published in the official statute book, both the issuance and renewal of a citizen station licence are set at 5 dollars. [16]

One should be careful with the date here.

I have not confirmed whether this "5 dollars" is the actual fee at the administrative counter as of 2026.

Therefore, rather than stating "it is still 5 dollars," I will state that it is 5 dollars in the 2008 revised edition of the regulations.

The same regulations also have a separate license category called an emergency station, which is listed as free of charge in the same fee schedule. [16]

While Vanuatu places emergency channels within CB, these Tuvalu regulations treat emergency stations as a separate category.

There is also a difference in where emergency communications are placed within the system.


Kiribati—CB definition can be confirmed, but the original source is currently 404

The search index for the Radiocommunications Rules, which was posted on the official website of the Communications Commission of Kiribati (CCK), still contains a description explaining a citizen band station as personal short-range two-way voice communication using the 27 MHz or 470 MHz bands. [17]

However, when I tried to open the official PDF directly this time, it resulted in a 404 error.

Therefore,

I can confirm from the search index on the official website that 'CB in the 27 MHz or 470 MHz band was defined by law in Kiribati,'

but I have not been able to re-verify the original text this time.

I will leave the specific channel center frequencies, modes, maximum output, and emergency channels as unknown.


Fiji—Handling 27 MHz handheld units through licensing administration

The current fee schedule from the Telecommunications Authority of Fiji (TAF) explicitly lists 27 MHz hand-held transceivers. [18]

In the fee categories,

  • RF output of 50 mW or less

  • those exceeding 50 mW

are separated.

Furthermore, for 27 MHz equipment, output categories of 12 W or less for land use and 25 W or less for maritime use can also be confirmed. [18]

Therefore, 27 MHz handheld radios are also recognized as a distinct equipment category for administrative purposes in Fiji.

On the other hand, from this fee schedule,

  • whether it is 40-channel CB

  • what is used, such as AM or SSB

  • or if there are special channels like ch 9

is not known.

I will not fill in these gaps with the systems of other countries either.


Niue—Voice communication prohibited even without a license

The Radio Regulations included in the Niue government's collection of laws contain an old form of license-free system called Restricted radiation devices. [19]

Devices that meet certain conditions do not require a license.

The main conditions include:

  • Normal operating frequency: 10 to 150 kHz

  • Communication distance: 50 ft, approximately 15.24 m or less

  • Electric field strength at 50 ft: 15 µV/m or less

and so on. [19]

Furthermore, a microphone for voice reproduction must not be connected. [19]

Here, even if low-power radio transmission is permitted, it is not allowed to be used for human-to-human voice communication like a walkie-talkie.

This is a very clear example that SRD and voice communication are separate system concepts.


Solomon Islands—Details of CB could not be confirmed this time

The Telecommunications Commission Solomon Islands (TCSI) issues spectrum licenses for land mobile, maritime mobile, fixed service, amateur, etc. [20]

However, from the official public documents that could be confirmed this time, it was not possible to obtain a detailed table of channels, modes, and output for general public CB or license-free walkie-talkies like in Vanuatu.

Therefore, what can be said about the Solomon Islands in this report is limited to the fact that frequency usage is managed under a licensing system.

The specific system for CB remains unknown.


Cook Islands—Frequency management agency can be confirmed, but details of CB/SRD are unknown

The Competition and Regulatory Authority (CRA) of the Cook Islands is responsible for frequency management under the Telecommunications Act 2019. [21]

However, the Radio Spectrum and Technical Matters section of the CRA official website still has parts marked as Under Construction, and it was not possible to confirm specific technical tables for CB, license-free walkie-talkies, or SRD this time. [21]

Therefore, the details are treated as unknown.

Regarding Nauru and Palau as well, since it was not possible to sufficiently confirm the original sources that could determine the frequencies, modes, output, and special channels required for this report during this re-confirmation, technical values by country will not be forcibly listed.


SRD—There are more wireless devices that humans are not conscious of

When thinking based on walkie-talkies, a "radio" looks like a device that a person holds in their hand and speaks into.

However, when looking at SRDs, that image changes.

In Samoa, automotive keyless entry systems in the 433 MHz band transmit using ASK or FSK.

TPMS sends tire status to the vehicle body at 433.92 MHz, 1 mW ERP, using FSK.[2]

Bluetooth uses GFSK, π/4 DQPSK, 8DPSK, etc., in the 2.4 GHz band.[2]

Users do not think, "I am going to use a radio now."

They press a button on their car. They start the engine. They connect earphones.

With just that, a small transmitter is operating.

When considering modern license-free radio wave systems, while CB and walkie-talkies are prominent, the world of SRDs exists even more broadly around them.


12 W, 5 W, 10 mW, 1 mW

The output of consumer radios differs by orders of magnitude depending on the application.

There are documents indicating that 12 W PEP is permitted for 27 MHz SSB CB in Vanuatu, and 5 W carrier power for UHF CB.[1]

On the other hand, there are values such as 10 mW ERP for non-specific SRDs and 1 mW ERP for TPMS in Samoa.[2]

However,

  • PEP

  • carrier power

  • effective radiated power (ERP)

  • equivalent isotropically radiated power (EIRP)

are not the same measurement methods.

It is not appropriate to evaluate how many times stronger something is by simply lining up numbers.

What is important is the application.

CB, which allows people to talk while apart, requires an appropriate level of output.

A car key only needs to reach the car.

TPMS only needs to reach from the tire to the vehicle body.

The SRD system clearly reflects the concept of having radio waves reach only as far as necessary to perform the required task.


Why CB and walkie-talkies remain in the mobile phone era

Mobile phones and CB have different roles.

Mobile phones are suited for calling a specific person from a distance.

CB and walkie-talkies allow multiple users to share a single channel, and by pressing the Push-to-Talk (PTT) button, one can deliver their voice immediately on the spot.

In the application form for the Federated States of Micronesia, both personal and business use are envisioned. [13]

In the Marshall Islands, VHF/CB training for local governments appears in government plans. [15]

In Vanuatu, there are documents showing that CB is open to citizens under a GURL, and an emergency-only channel is also institutionalized. [1][5]

Work, vehicles, regional communication, local administration, and emergencies.

In these situations, direct communication radio retains its own unique uses even in a society where mobile phones are widespread.


Institutional similarities with neighboring countries

476–477 MHz UHF CB appears in multiple South Pacific countries.

Regarding 245 MHz class VHF CB, a strong similarity can be seen between the Thai system and old consultation documents from Tonga.

The 2026 LIPD/SRD revision proposal for Papua New Guinea also contains parts designed with reference to the Australian system. [9]

It is difficult to explain these similarities solely through colonial history.

It is also necessary to consider ongoing factors such as radio equipment circulating in neighboring countries, technical standards, technical cooperation from organizations like the International Telecommunication Union (ITU), and regional frequency harmonization.

Regarding the 245 MHz CB in particular, although similar numbers appear between Thailand, Tonga, and Timor-Leste, the original source indicating the path through which the system was transmitted could not be confirmed this time.

Similarity and the ability to prove origin are two different things.


Even with the same 'Citizens Band' radio, the systems differ.

Summarizing the picture visible from the materials of Pacific Island countries, there are significant differences.

  • Vanuatu has a CB system based on GURL, and from official documents, one can confirm quite specific details such as 27 MHz, 477 MHz, output, mode, and emergency channels.

  • Samoa has 27 MHz and 477 MHz CBRS in its national frequency table, and for SRD, details such as frequency, output, and modulation method are publicly available.

  • Papua New Guinea has 27 MHz and 477 MHz CBRS bands, but I could not re-acquire the full text of TR603 this time, so detailed output and mode information are reserved. The 2026 LIPD/SRD material is a draft revision.

  • Tonga had its 245 MHz and 477 MHz CB mentioned in old government consultation materials from 2021, but I cannot re-acquire the original PDF at this time.

  • Federated States of Micronesia requires individual licenses for CB, assuming both personal and business use.

  • Marshall Islands shows CB licensing, inspections, and training for local governments in administrative documents.

  • Tuvalu has a Citizen Station Licence, and the 2008 revised legislation classifies emergency stations separately.

  • Fiji specifies 27 MHz handheld transceivers in its licensing and fee structure, but I could not confirm channels or modes this time.

  • Niue has a license-free low-power equipment system, but the relevant old system does not permit the connection of voice microphones.

  • Kiribati, Solomon Islands, Cook Islands, etc. could not have their CB/SRD technical conditions determined with the same precision from the publicly available original sources this time.

'Unknown' does not mean the system does not exist.

It means it cannot be confirmed from public documents or the original source could not be re-acquired this time.


Conclusion: Small communication networks in the air of the islands

On 27.065 MHz, people prepare for emergency communications.

On 245.5000 MHz, citizens band users in Thailand prepare for disaster prevention and emergency communications.

476.525 MHz and 477.275 MHz are designated as dedicated emergency communication channels for UHF CB in Vanuatu.

At 433.92 MHz, tire sensors report their status to the vehicle.

At 2.4 GHz, personal devices exchange short pieces of information with each other.

Even for the same "radio waves open to the public," the form differs depending on the country.

Some countries open them up through class licenses.

Some countries retain individual licensing.

Some countries establish emergency channels within the CB band.

Some countries strictly define frequencies, modulation methods, and radiated power for low-power devices.

And as one follows the documentation, another thing becomes clear.

Even if similar frequencies or channel configurations appear across borders, their origins are not always known. One must verify one by one whether old regulations are still in effect, whether a draft proposal was officially adopted, or whether an old official PDF is still accessible.

In the air over Pacific Island countries, various small radio signals are flying, including human voices, work communications, emergency calls, vehicles, alarms, and sensors.

What supports them is not just "which MHz to use."

To whom are the radio waves opened?

What level of output is permitted?

Where should people gather in an emergency?

And how are short communications between people and machines integrated into society?

By following small walkie-talkies and SRDs, one can even see how the islands think about public radio waves.
