ATU-10 ATU10 QRP by N7DDC Automatic Antenna Tuner 1.4 Version

Now it is 1.4 Version:

New in FW version 1.4

1 - The button glitches solved

2 - More stability in bus transfer to OLED

3 - No continious data transferring to the display

Input power: Minimum 1W, Maximum 15W

The control button has only 3 functions ：

1. a short press resets the tuner and sets all relays to their initial state, in which all reactive elements are disabled and do not affect the signal flow through the tuner,

2. a long press causes the tuner to enter the tuning mode

3. a very long press for more than 5 seconds causes the firmware version to be displayed on the display.

The tuner has 3 power consumption modes:

1. the operating mode, when the display indicates the parameters, lasts 5 minutes,
