Ham radios, also known as amateur radios, are popular among enthusiasts who enjoy communicating across distances without relying on the internet or cell networks. These radios can be used for socializing, emergency communication, and even technical experimentation. The power supply for a ham radio is a critical component that ensures the efficient operation of your equipment, as it converts household AC power into the DC power that ham radios require.
The ideal power supply for ham radio must provide a clean and stable voltage to optimize both the performance and longevity of the radio. Different types of power supplies exist, including linear and switching models. Linear power supplies are known for their exceptionally stable outputs and low electrical noise, which is essential for clear radio transmissions. Switching power supplies, on the other hand, are more compact and energy-efficient, making them a solid choice for many users.
When choosing a power supply, one must consider factors like the maximum current output, the stability of the voltage, the size, weight, and the amount of radio frequency interference (RFI) it might produce. A higher current rating than your radio’s maximum draw is advisable to ensure headroom for peak demands. Appropriate cooling mechanisms to prevent overheating and adjustable voltage features are also beneficial aspects to look out for.
Our examination of various power supplies aims to connect you with a product that not only aligns with the technical demands of your ham radio setup but also fits your individual preferences for operation and maintenance. We have meticulously analyzed and tested a variety of power supplies to assist you in making an informed choice, prioritizing the performance, and reliability essential to amateur radio operations.

Frequently Asked Questions
When selecting a power supply for ham radios, understanding the intricacies can greatly improve your radio experience and performance.
What are the pros and cons of linear vs. switching power supplies for ham radios?
Linear power supplies are known for their clean power output with very low ripple and noise, which is a significant advantage for audio clarity in ham radios. However, they tend to be heavier and less efficient than switching power supplies, which are more compact and energy-efficient but can introduce noise that may interfere with radio operation if not properly filtered.
How do I determine the appropriate amperage for a power supply when setting up my ham radio?
To determine the correct amperage, review the specifications of your ham radio to find the maximum current draw. Our recommendation is to choose a power supply that can provide at least 20-30% more current than your radio requires to ensure it can handle peak demands without stressing the power supply.
Can a computer power supply be safely repurposed for ham radio use, and what modifications are needed?
Yes, a computer power supply can be modified for ham radio use. The modifications typically involve isolating the supply’s 12V outputs and equipping it with the appropriate connectors for your radio. It’s critical to make sure the power supply provides clean and stable voltage and can handle the current demands of the radio.
What features should I look for in a power supply to ensure the best performance of my ham radio?
Look for a power supply with good voltage regulation, low ripple, over-current and over-voltage protection, and an RF noise filter if choosing a switching supply. An adjustable voltage feature can also be beneficial for matching the exact needs of your radio.
How does voltage regulation impact the operation of a ham radio, and what voltage should I aim for?
Voltage regulation ensures a stable power output to your ham radio, regardless of fluctuating input voltage or variable load conditions. Aiming for a power supply that maintains a consistent 13.8V is ideal for most ham radios, as this closely simulates the voltage of an automotive electrical system, which many radios are designed to operate on.
Where can I find reliable reviews and comparisons of power supplies suitable for ham radio applications?
Reliable reviews and comparisons can be found in ham radio enthusiast forums, magazines, and online communities such as QRZ.com, eHam.net, and Reddit’s r/amateurradio. Vendors who specialize in ham radio equipment may also provide detailed information and comparisons of different power supply models.
