This in-depth review examines a highly capable amateur radio station bundle that combines the widely respected Icom IC-7300 HF/6-meter transceiver with the Intellitron PS-2275MA high-current switching power supply. Together, these two components form a solid foundation for a modern home or shack-based amateur radio setup suitable for a wide range of operating styles.
Overview of the Bundle
The Icom IC-7300 has become one of the most popular HF transceivers of the modern era due to its combination of advanced SDR technology, user-friendly interface, and reliable performance. When paired with the Intellitron PS-2275MA, a powerful 75-amp variable voltage power supply, the bundle provides both the radio and the electrical backbone needed for consistent 100-watt operation and future station expansion.
This bundle is well suited for operators interested in HF voice, CW, digital modes, contesting, DXing, and even 6-meter operation, all while maintaining a relatively compact and approachable station footprint.
Icom IC-7300 Transceiver
At the core of this bundle is the Icom IC-7300, a 100-watt HF and 50 MHz amateur radio transceiver built around a direct-sampling software-defined radio architecture. Unlike traditional superheterodyne designs, the IC-7300 digitizes RF signals directly, resulting in excellent receiver sensitivity, strong dynamic range, and reduced internal noise.
One of the most defining features of the IC-7300 is its large color touchscreen display with an integrated spectrum scope and waterfall. This allows operators to visually monitor band activity in real time, identify signals quickly, and adjust operating frequencies with precision. For both new and experienced operators, this visual feedback significantly improves situational awareness on crowded bands.
The radio supports all major operating modes including SSB, CW, AM, FM, and digital modes such as RTTY. Output power is continuously adjustable up to 100 watts on HF and 6 meters, making it suitable for both low-power experimentation and full-power base station operation.
An internal automatic antenna tuner is included and works well for antennas that are reasonably close to resonance. While it is not intended to match highly mismatched antennas, it is extremely convenient for everyday operation and simplifies station setup by reducing the need for external equipment.
Ergonomics are another strong point. The IC-7300 features a large tuning knob, clearly labeled controls, and a logical menu system that avoids excessive complexity. Noise reduction, filtering, and passband tuning are easy to adjust on the fly, allowing operators to tailor receive audio to difficult band conditions.
Audio quality on both transmit and receive is clean and intelligible, with enough customization options to suit different microphones and operating styles. Overall, the IC-7300 strikes a balance between modern digital performance and traditional hands-on radio operation.
Intellitron PS-2275MA Power Supply
The Intellitron PS-2275MA is a high-capacity switching power supply designed to meet the demands of modern amateur radio stations. With a maximum output of 75 amps and strong continuous current capability, it easily supports the IC-7300 at full transmit power while leaving plenty of overhead for accessories such as antenna tuners, VHF/UHF radios, or small amplifiers.
One of the standout features of this power supply is its variable voltage range, adjustable from approximately 4 to 16 volts DC. A standard 13.8-volt setting is ideal for most amateur radio equipment, while the adjustability provides flexibility for specialized devices or testing scenarios.
The front panel typically includes multiple connection options, such as binding posts and Powerpole connectors, making it easy to power multiple devices from a single supply. Built-in digital meters display voltage and current, allowing operators to monitor system performance at a glance.
Protection circuits are included for over-voltage, over-current, overheating, and short circuits. These safeguards help protect both the power supply and connected equipment during unexpected faults or heavy loads.
As a switching power supply, the PS-2275MA is significantly lighter and more compact than traditional linear supplies with similar output ratings. This makes it easier to place in a shack or transport if needed. While switching supplies can sometimes introduce RF noise, modern designs like this one generally perform well when properly installed and grounded.
Real-World Performance as a Station
When used together, the IC-7300 and PS-2275MA form a reliable and flexible amateur radio station. The power supply delivers stable voltage even during long transmissions, preventing power sag that can affect transmit quality. The radio’s SDR receiver, combined with stable power, allows for excellent weak-signal performance and consistent operation across all supported bands.
This bundle is suitable for a wide range of operating styles. Casual operators will appreciate the ease of use and visual band display, while more advanced users will benefit from the radio’s filtering options, digital mode compatibility, and clean transmit signal. The power supply’s generous capacity also allows room for station growth without immediate upgrades.
Conclusion
The Icom IC-7300 100W HF/50MHz SDR Amateur Radio Transceiver paired with the Intellitron PS-2275MA 75-amp variable voltage switching power supply is a well-rounded bundle that delivers both performance and flexibility. The IC-7300 continues to stand out as one of the most capable and approachable HF transceivers available, offering modern SDR features without sacrificing traditional operating feel. The Intellitron power supply provides ample, stable power and the versatility needed for a growing station.
For amateur radio operators looking to build or upgrade a serious HF base station, this bundle offers an excellent balance of technology, usability, and expandability, making it suitable for beginners stepping into HF as well as seasoned operators seeking a dependable everyday rig.
