Tomshoo ATU-100-0A 1.8-55MHz Automatic Tuner 0.91inch OLED Display Aluminum Alloy Outcase with1800MAh Battery

The shortwave automatic tuner contains a set of 7 capacitors and 7 inductors which allows it (with the largest configuration) to work effectively in a wide frequency band overlapping the amateur HF band of 1.8-30MHz. Built-in lithium battery 3.7V 1800mAh you can use Type-C cable to recharge it. Equipped with 0.91inch OLED display you can see the data clearly. Automatically tuned and do not need control wires suitable for most stations. You can have a try. Features: The shortwave automatic tuner contains a set of 7 capacitors and 7 inductors which allows it (with the largest configuration) to work effectively in a wide frequency band overlapping the amateur HF band of 1.8-30MHz. Made of quality material wear resistance with stable and reliable performance. Built-in lithium battery 3.7V 1800mAh you can use Type-C cable to recharge it. Equipped with 0.91inch OLED display you can see the data clearly. Automatically tuned no human and control wires are required and it is suitable for most stations. One button to onoff easy to use very convenient. Instructions: Connect the ATU tuner and . For the first use please set the output power of the or power between 20-30W or the high-power tuning can easily damage the tuner. Set the mode use frequency modulation mode. Choose the band to use use 20-30W power in frequency modulation mode press the PTT observe the PWR and SWR of ATU tuner. ATU button TUNE use: short press (less than 1 second) ATU button it is in reset state long press (more than 1 second) ATU button is in tuning state. If the SWR display of the ATU tuner in the transmitting state is ＞2.0 it means that the is detuned.6.You need to use an tuner. Press and hold the ATU button tune to tune and observe the SWR value. If the SWR is greater than 3.0 after tuning the will be detuned. In serious cases it is not recommended to use more than 30W power and the transmission power should be controlled below 30W; If the tuning is completed the SWR display is less than 2.0 and the maximum power of 100W can be used for transmission.
