Review YAESU Box Amplifier Relay

The FRB-757 Box Amplifier Relay from Yaesu is a high-quality, reliable, and versatile component designed for amateur radio operators and communication enthusiasts. This relay module is specifically engineered to control power to your amplifier, ensuring safe and efficient operation.

The FRB-757 is a 75-ampere, SPDT (Single Pole Double Throw) relay, which means it can switch between two circuits while simultaneously maintaining a connection to a third. This makes it an excellent choice for switching between a low-power and high-power amplifier, or for other applications where multiple power sources need to be managed.

The relay is housed in a robust, weather-resistant box, making it suitable for both indoor and outdoor use. It features a screw terminal design for easy and secure connection to your amplifier and power supply. The box also includes a remote control input, allowing you to switch the relay on or off using a momentary push-button switch, a mini DC relay, or a footswitch.

The FRB-757 is built with durability in mind. It uses high-quality contact materials to ensure reliable operation, even under heavy load. The contacts are gold-plated, ensuring a low contact resistance and minimizing arcing and sparking. The relay also includes a built-in diode to prevent backfeed, protecting your power supply from damage.

The FRB-757 is an excellent choice for any amateur radio operator or communication enthusiast who needs a reliable, easy-to-use, and high-performance relay module for their amplifier. Its robust design, versatile features, and high power handling make it a valuable addition to any radio station.

1. Compatibility: The FR-B757 is specifically designed for Yaesu transceivers, ensuring a seamless integration with your existing setup.

2. Quality Build: The relay is known for its robust construction, which can withstand heavy usage and harsh environmental conditions.

3. Reliability: With its high-quality components and reliable performance, the FR-B757 can significantly reduce the risk of equipment failure.

4. Easy Installation: The relay is easy to install and requires minimal setup, saving you time and effort.

1. Cost: Compared to some alternatives, the FR-B757 can be relatively expensive, which might be a deterrent for budget-conscious buyers.

2. Limited Functionality: While the FR-B757 is a reliable and high-quality relay, it may not offer all the features that more advanced or expensive models do.

If you are looking for a reliable and high-quality amplifier relay for your Yaesu transceiver and are willing to pay a premium for such a product, the FR-B757 is a great choice. Its robust construction, reliability, and easy installation make it an excellent option for serious ham radio enthusiasts. However, if you are on a tight budget or require more advanced features, you may want to consider alternative options.

If you decide to purchase the FR-B757 Box Amplifier Relay for Yaesu, make sure to follow the manufacturer's instructions carefully to ensure proper installation and operation. Additionally, consider investing in a reliable power supply to ensure the longevity of your relay and prevent any potential damage to your Yaesu transceiver.

Details:

Fast 3 day offer to move this along. This permits the newer solid state radios to function with the older tube type amplifiers using high voltage switching relays. This item was in use until I changed to a hibachi soft key external box for my Sb 200 amplifier which provided me with a standby switch for the amp.

Box and instructions schematic are included. This is a used but fully functional and hard to find frb 757 relay box for use with the Yaesu ft 747, ft 757 and other Yaesu radios.
