Imagine operating your entire ham radio station remotely — from anywhere in the world — using only a web browser and a Raspberry Pi. Sounds futuristic? Not anymore.

Introducing Simple Ham Radio Remote (SimpleHRR) — a lightweight, browser-based web app designed for amateur radio operators who want to remote control their transceivers over the Internet. Whether you’re using a PC, laptop, Android phone, or iPhone (Safari tested), SimpleHRR brings your station to your fingertips — no extra software, no complex wiring, no subscription fees.

What Is SimpleHRR?

SimpleHRR (Simple Ham Radio Remote) is a web-based remote control system hosted on a low-cost Raspberry Pi (or Le Potato) that connects directly to your amateur radio transceiver via USB and your home network via Ethernet.

No SCU-LAN10.
No Remote Desktop.
No TeamViewer.
Just a browser — that’s it.

Key Features

• Full Radio Control: Power, Band, Mode, VFO, TX/RX settings, filters, notch, gain — everything is right there.
• Two-Way Audio: Talk and listen directly from the browser — no need for Mumble, Skype, or other VOIP software.
• Integrated Webcam Feed: Keep an eye on your shack or monitor your equipment remotely.
• Web Server Included: Host your own station schedule or control page.
• Multi-User Support: Set up individual accounts for club members or shared stations.
• Browser-Based UI: Fully functional interface using mouse wheel and keyboard shortcuts (e.g., spacebar for PTT).
• Smart Fail-Safe: Automatically turns off radio if the connection drops — no risk of accidental transmissions.

Radios Supported

Currently tested with:

Icom: IC-7300, IC-7610, IC-705 (HF/VHF/UHF), IC-2730A

Amateur radio operations in Malaysia follow international standards and frequencies, making it possible for operators worldwide to communicate seamlessly. The Malaysian Communications and Multimedia Commission (MCMC), also known as SKMM, serves as the regulatory authority overseeing all amateur radio activities in the country.

Who Can Apply for a Malaysian Amateur Radio License?

There are two main categories of applicants:

Malaysian Citizens and Residents: Individuals who wish to establish and operate their own amateur radio station in Malaysia must obtain Amateur Station Apparatus Assignment (ASAA).

Foreign Amateur Radio Operators: Licensed amateur radio operators from countries that maintain reciprocal agreements with Malaysia may apply for temporary operating privileges during their stay.

Before You Begin: Review The Guidelines

Before starting your application process, it’s essential to review the official guidelines. MCMC provides comprehensive guidelines that outline all requirements, procedures, and regulations for amateur radio operations in Malaysia. These guidelines contain crucial information that will help you understand the complete licensing process and ensure your application meets all requirements.

Foreign Amateur Radio Operators: Temporary Operating Permits

Foreign amateurs visiting Malaysia can obtain temporary operating privileges through a streamlined process managed by the Malaysian Amateur Radio Transmitters Society (MARTS). This organization serves as the liaison between foreign operators and MCMC.

Required Documentation

Foreign applicants must prepare the following documents:

1. Completed Application Form – Download the official form and fill it out completely
2. Amateur Radio License Copy – A clear photocopy of your current amateur radio operator certificate from your home country
3. Passport Information – Photocopy of your passport’s photograph page
4. Visa Documentation – If applicable, include a copy of your Malaysian visa
5. Work Permit – Copy of your Malaysian work permit (if you’re working in Malaysia)
6. Society Endorsement – A support letter from your home country’s amateur radio society, which must be a member of the International Amateur Radio Union (IARU)

Application Timeline and Submission

Foreign operators should plan ahead, as the application process requires time for review and approval. Submit all required documents at least two months before your intended operating dates.

Submit Applications To: secretary@marts.org.my

MARTS will provide information once they receive your complete application package. They handle the coordination with MCMC and will guide you through any additional requirements.

Understanding Malaysian Amateur Radio Regulations

Malaysia’s amateur radio service operates under comprehensive telecommunications legislation. The primary governing documents include the Communications and Multimedia Act 1998 and various technical standards regulations.

Tips for a Successful Application

Documentation Quality: Ensure all photocopies are clear and legible. Poor quality documents can delay processing.

Complete Information: Double-check that all forms are completely filled out. Missing information is a common cause of application delays.

Professional Presentation: While amateur radio is a hobby, approach the application process professionally. Regulatory authorities appreciate well-organized, complete submissions.

Follow Up Appropriately: After submitting your application, allow adequate processing time before following up. Each application requires review and verification.

International Reciprocal Agreements

Malaysia maintains reciprocal operating agreements with numerous countries, allowing their licensed amateurs to operate in Malaysia under temporary permits. These agreements facilitate international amateur radio activity and emergency communications cooperation.

Final Considerations

Amateur radio licensing involves both privileges and responsibilities. Licensed operators must comply with all applicable regulations, maintain proper station records, and operate within their license class privileges.

Whether you’re a Malaysian resident seeking your first amateur radio license or a foreign amateur planning to operate during a visit, thorough preparation and attention to regulatory requirements will ensure a smooth application process.

Remember that amateur radio serves not only as a technical hobby but also as a vital emergency communication resource. Your participation contributes to a worldwide network of skilled operators ready to provide communication support when traditional systems fail.
