The Directorate General of Digital Infrastructure (DJID) has issued a new technical regulation of KEPMEN KOMDIGI No 44 year 2025 regarding technical standard for amateur radio transceiver equipment in Indonesia. The ministerial decree number 44 has been promulgated since 18 February 2025 and should come into effect 6 months after its promulgation. Therefore, this new technical regulation should come into effect on 18 August 2025. Amateur radio transceiver test reports that have been issued before this ministerial decree comes into effect can still be submitted for DJID certification.
In this article we will discuss all about the new technical standards of amateur radio transceiver equipment and its impact for current certification process.
General technical requirements for amateur radio transceiver equipment
In general, technical requirements for amateur radio transceiver equipment that need to be met for DJID certification process including power supply, non-ionizing radiation, electrical safety, electromagnetic compatibility, and radio frequency requirements.
Power supply requirements
Amateur radio transceiver equipment can be powered by AC or DC power. All parameter benchmarks must be met when using a power supply within the AC voltage range of 220 V ± 10% and a frequency of 50 Hz ± 2%. When using an external power supply such as AC/DC power converter, the external power supply must not affect amateur radio transceiver equipment ability to meet all technical parameter benchmarks.
Non-ionizing radiation requirements
Non-ionizing radiation is typically a form of low-frequency electromagnetic radiation produced by ICT devices attached to the human body. The amount of electromagnetic radiation absorbed by the human body is typically measured during Specific Absorption Rate (SAR) testing.
Electrical safety requirements
Electrical safety assessment for amateur radio transceiver equipment have to meet two parameters of electrical safety below:
- Over voltage or electrical strength or dielectric strength
- Leakage current or touch current
Electrical safety assessment for amateur radio transceiver equipment shall meet the requirements specified in standards of IEC 62368-1 or IEC 60950-1.
Electromagnetic compatibility (EMC) requirements
Amateur radio transceiver equipment should be classified as:
- Fixed equipment: devices installed permanently and powered by AC power
- Vehicular equipment: devices used in vehicles and powered by the vehicle’s main battery
- Portable equipment: devices designed for portable use and powered by batteries
Amateur radio transceiver equipment should meet EMC immunity and emission requirements. The parameters and mechanisms for implementing EMC immunity will be regulated by different ministerial decrees. Meanwhile, the EMC emission parameters that have to be met are:
- EMC radiated emissions in the enclosure of ancillary equipment
- EMC conducted emissions on AC, DC, or AC/DC converter ports
- EMC conducted emissions on telecommunications network ports
Each EMC emission parameter needs to be classified whether it is class A or class B according to the standard of IEC CISPR 32 or ETSI EN 301 489-1.
Radio frequency requirements for amateur radio transceiver equipment
Amateur radio transceivers are only permitted to operate on frequency bands specifically allocated for amateur radio services under national spectrum regulations. Details of the frequency allocations are shown in the following table:
| Types of radio frequency bands | Radio frequency range | Conducted output power |
| LF | 135.7 – 137.8 kHz | ≤ 200W |
| MF | 472 – 479 kHz | ≤ 200W |
| 1800 – 2000 kHz | ||
| HF | 3500 – 3900 kHz | ≤ 200W |
| 5351.5 – 5366.5 kHz | ||
| 7000 – 7200 kHz | ||
| 10100 – 10150 kHz | ||
| 14000 – 14350 kHz | ||
| 18068 – 18168 kHz | ||
| 21000–21450 kHz | ||
| 24890–24990 kHz | ||
| 28000–29700 kHz | ||
| VHF | 50–54 MHz | Handheld: ≤ 10W Mobile : ≤ 200W Base/Repeater : ≤ 200W |
| 144–148 MHz | Handheld : ≤ 10W Mobile : ≤ 100W Base/Repeater : ≤ 100W | |
| UHF | 430–440 MHz | Handheld : ≤ 10W Mobile : ≤ 100W Base/Repeater : ≤ 100W |
| 1240–1300 MHz | ≤ 10W | |
| 2300–2450 MHz | ≤ 2W | |
| SHF | 3300–3500 MHz | ≤ 2W |
| 5650–5850 MHz | ≤ 2W | |
| 10000–10500 MHz | ≤ 0,5W |
The spurious emissions limits for amateur radio transceiver equipment must comply with:
- For Amateur Radio Transceivers operating at frequencies ≤ 30 MHz, they must meet an emission attenuation of at least 43 + 10 log (P) dB, where P is the output power (conducted) or 50 dBc, whichever is less stringent.
- For Amateur Radio Transceivers operating above 30 MHz, they must meet an emission attenuation of at least 43 + 10 log (P) dB, where P is the output power (conducted) or 70 dBc, whichever is less stringent.
Conclusion
It is important for applicants to stay updated with any changes in technical regulations of Indonesia type approval, such as the issuance of the technical regulations for amateur radio transceiver equipment. Generally, the implementation of new technical regulations can cause confusion in the initial process. To facilitate this adjustment period, applicants can consult with a type approval service company. Therefore, feel free to send an email to info@narmadi.com if you have any questions about this new technical regulation.
