Icom AT-130 Tuner Specification

The Icom AT-130 is an automatic antenna tuner designed for seamless integration with Icom HF marine transceivers, facilitating optimal performance in a wide range of marine communication scenarios. Operating efficiently across the HF marine band, the tuner automatically matches the antenna's impedance to the transceiver, ensuring minimal signal loss and maximum transmission efficiency. It supports a frequency range from 1.6 to 30 MHz, accommodating various communication needs from short-range to long-distance transmissions.

The AT-130's robust construction is tailored to withstand harsh marine environments, featuring a weather-resistant enclosure that protects its internal components from saltwater, humidity, and temperature extremes. The tuner requires a power supply of 13.8 V DC, drawing minimal current, which makes it suitable for marine vessels where power efficiency is crucial. It automatically stores tuning settings for up to 45 channels, significantly reducing retuning time when switching frequencies.

The unit's compact design allows for flexible installation in space-constrained environments typical of marine vessels. Weighing approximately 3.9 kg, the AT-130 is lightweight yet sturdy, and its dimensions (340 mm x 230 mm x 80 mm) make it easy to mount in various marine settings. The tuner interfaces seamlessly with compatible Icom transceivers, using a control cable for automatic operation, thus eliminating the need for manual tuning adjustments.

Reliability and ease of use are at the core of the AT-130's design, ensuring that operators can maintain clear and consistent communication without technical interruptions. Its performance, durability, and user-friendly operation make it an indispensable component for maritime communication systems.

Icom AT-130 Tuner F.A.Q.

How do I connect the Icom AT-130 tuner to my transceiver?

To connect the Icom AT-130 tuner to your transceiver, use a coaxial cable to connect the 'TX' port on the tuner to the antenna connector on the transceiver. Ensure the control cable is connected to the appropriate tuner control port on the transceiver.

What is the procedure for tuning the Icom AT-130?

To tune the Icom AT-130, switch the transceiver to a low power setting and key the transmitter. The tuner will automatically begin the tuning process. Wait until the tuning cycle is complete and the SWR is minimized.

How can I reset the Icom AT-130 tuner?

To reset the Icom AT-130 tuner, disconnect the power supply, wait for about 10 seconds, and then reconnect the power. This will reset the tuner's internal settings.

What should I do if the tuner is not tuning properly?

If the tuner is not tuning properly, check all cable connections for security and integrity. Ensure that the antenna is correctly installed and that the transceiver is set to the correct frequency range.

Can the AT-130 tuner handle high power transmissions?

The Icom AT-130 tuner is designed for operation with transceivers up to 150 watts PEP. Exceeding this power level may damage the tuner.

How do I perform routine maintenance on the Icom AT-130?

Routine maintenance for the Icom AT-130 includes checking and securing all electrical connections, inspecting cables for wear, and cleaning the unit's exterior with a soft, dry cloth.

What types of antennas are compatible with the AT-130?

The Icom AT-130 is compatible with a wide range of HF antennas, including wire antennas, dipoles, and verticals. Ensure that the antenna is rated for the frequency and power levels you intend to use.

Is the AT-130 suitable for marine environments?

Yes, the Icom AT-130 is designed to be used in marine environments. It is built to withstand exposure to salt, moisture, and temperature variations.

How can I improve the tuning speed of the AT-130?

To improve the tuning speed, ensure the antenna system is properly installed and relatively resonant at your operating frequencies. Regularly clean and check all connections to minimize resistance and interference.

What should I do if the AT-130 does not power on?

If the AT-130 does not power on, check the power connections and ensure that the power source is active. Inspect the control cable for damage and verify that it is securely connected to the tuner and the transceiver.
