Malaysian Amateur Radio Bands Guide
Complete guide to amateur radio frequency bands available in Malaysia. Covers VHF, UHF, and HF allocations, repeater offsets, band plans, and operating conventions.
Overview of Malaysian Amateur Radio Bands
Malaysian amateur radio operators, licensed by the Malaysian Communications and Multimedia Commission (MCMC), have access to several frequency bands across the HF, VHF, and UHF spectrum. The most commonly used bands for local communication are the 2-meter VHF band (144–148 MHz) and the 70-centimeter UHF band (430–440 MHz). These bands support simplex operation, repeater operation, digital modes like DMR, and packet radio including APRS.
VHF Band - 2 Meters (144–148 MHz)
The 2-meter band is the most popular amateur radio band in Malaysia for local and regional voice communication. It supports simplex (direct radio-to-radio) and repeater operation.
| Segment | Frequency Range | Use |
|---|---|---|
| 144.000–144.100 | 144.000–144.100 MHz | CW (Morse Code) |
| 144.100–144.400 | 144.100–144.400 MHz | SSB / Digital modes |
| 144.390 | 144.390 MHz | APRS (Automatic Packet Reporting System) |
| 144.400–145.800 | 144.400–145.800 MHz | FM simplex & repeater inputs |
| 145.000 | 145.000 MHz | National simplex calling frequency |
| 145.200–145.800 | 145.200–145.800 MHz | Repeater outputs (with -0.6 MHz offset) |
| 145.800–146.000 | 145.800–146.000 MHz | Satellite / Space communications |
| 146.000–147.000 | 146.000–147.000 MHz | FM simplex channels |
| 147.000–148.000 | 147.000–148.000 MHz | Repeater outputs & simplex |
Repeater offset: ±0.6 MHz (600 kHz). Most Malaysian VHF repeaters use a negative offset. For example, a repeater output on 147.980 MHz has an input on 147.380 MHz.
UHF Band - 70 Centimeters (430–440 MHz)
The 70cm band is the second most popular band in Malaysia, offering good penetration through buildings and supporting both FM and digital modes like DMR (Digital Mobile Radio).
| Segment | Frequency Range | Use |
|---|---|---|
| 430.000–433.000 | 430.000–433.000 MHz | Repeater inputs & digital modes |
| 433.000–434.000 | 433.000–434.000 MHz | ATV (Amateur Television) / Digital |
| 434.000–438.000 | 434.000–438.000 MHz | Repeater inputs (with -5 MHz offset) |
| 438.000–440.000 | 438.000–440.000 MHz | Repeater outputs & simplex |
| 439.600 | 439.600 MHz | 9M2RKL repeater (Kuala Lumpur) |
Repeater offset: -5.0 MHz (5 MHz). For example, a repeater output on 439.600 MHz has an input on 434.600 MHz. Several Malaysian UHF repeaters also support DMR mode, connected to networks like Brandmeister.
PMR446 (446.000–446.200 MHz) - License-Free
While not technically an amateur radio band, PMR446 is included in our database because many Malaysian ham radio operators also use PMR446 for license-free personal communication. PMR446 has 16 channels from 446.00625 to 446.19375 MHz with 0.5W maximum power. See our PMR446 guide for full details.
HF Bands (Shortwave)
Malaysian amateur radio operators with full licenses also have access to HF (High Frequency) bands for long-distance (DX) communication. HF signals bounce off the ionosphere, enabling worldwide communication.
| Band | Frequency Range | Common Use |
|---|---|---|
| 80 meters | 3.500–3.900 MHz | Nighttime regional NVIS |
| 40 meters | 7.000–7.200 MHz | Day/night medium distance |
| 20 meters | 14.000–14.350 MHz | Daytime DX (most popular HF band) |
| 15 meters | 21.000–21.450 MHz | Daytime DX during high sunspot |
| 10 meters | 28.000–29.700 MHz | Daytime DX, FM repeaters |
Repeater Operation in Malaysia
Repeaters are automated relay stations that receive on one frequency and retransmit on another, extending the communication range of mobile and handheld radios. Malaysia has an extensive network of repeaters covering all states, typically located on mountain tops and high buildings.
How to Use a Repeater
- Program the repeater's output frequency into your radio
- Set the correct offset (0.6 MHz for VHF, 5.0 MHz for UHF)
- Set the correct CTCSS tone (e.g., 88.5 Hz, 203.5 Hz)
- Press PTT to transmit - your radio shifts to the input frequency automatically
- Listen for the repeater's beep (courtesy tone) before responding
- Pause between transmissions to allow others to break in

Digital Modes in Malaysia
DMR (Digital Mobile Radio)
Several Malaysian repeaters support DMR digital mode, including 9M2RKL-DMR (Kuala Lumpur), 9M4RXC-DMR (Penang), and 9M2RBB-DMR (Penang). These repeaters are connected to the Brandmeister Network, enabling worldwide digital voice communication through Talk Groups.
APRS (Automatic Packet Reporting System)
APRS operates on 144.390 MHz in Malaysia. It's used for real-time position reporting, weather station data, and short text messages. APRS digipeaters and iGates relay packets across the network.
ASTRA Transnasional Linking
Several Malaysian repeaters are part of the ASTRA Transnasional linking network, which connects repeaters across different states via the internet or RF links, allowing operators to communicate over very long distances through the linked system.
CTCSS and DCS Tones
Malaysian repeaters use CTCSS (Continuous Tone-Coded Squelch System) or DCS (Digital-Coded Squelch) tones to control access. You must program the correct tone to activate a repeater. Common CTCSS tones used in Malaysia:
| Tone (Hz) | Common Use |
|---|---|
| 67.0 | 9M4RGT (Tumpat, Kelantan) |
| 85.4 | 9M4RBD, 9M4RAC, 9M4RUB |
| 88.5 | Simplex channels, many repeaters |
| 103.5 | 9M4RGH, 9M4RPS, many Perak repeaters |
| 118.8 | 9M4RCA, 9M4RCZ, 9M4RCD (Pahang) |
| 127.3 | 9M4RML, 9M4RPL, 9M4RJM (Melaka/Johor) |
| 203.5 | 9M2RKL, 9M2RKK, many repeaters |
| 233.6 | 9M4RZS, 9M4RNS |
