NOTE:Recommended maximum power while tuning not above 30 watts. (after tuning you can set 100 watts and work on this power)
SWR greater than 1.1 will automatically activate tuning, and the minimum power has been changed from 5W to 1W.
After modification, it can be tuned below 5W.Too low value may result in insufficiently fine tuning (original default is greater than 5W auto tuning), please know before placing an order.
All use Samsung SMD capacitors, C-channel capacitors, we use Samsung 1000V high-voltage SMD capacitors (the original default uses 500V), and the PIC chip imported from the United States.

The latest firmware version is 3.2
New in the version 3.2
1.Fixed bug with continuous data transfer to the display.
2.Added a new ability to disable all relays along with the timer display. New cell 35-01 to activate the refunction. Display Off Timer setup – cell 32.You can use this future in your QRP setup where power consumption is critical.
3.Timeout for display reset increased to 2 seconds. This is required for some OLED displays with a very chain on the reset pin.
NOTE：Green and Blue board
The boards of this series of products are available in blue and green in our shop: the functions are the same, and the ones you receive may be green or blue, which is a surprise!
Notice：
Machine introduction:
SIZE: 140 x 88 x 38 mm (L*W*H)
Machine: There are 2 modes: automatic mode and manual mode tuning function.
（1）Machine UHF:
Machine UHF: Include
1. Finished machine x1 (default SMA female connectors, it can be used after connecting the device to power supply.)
2. DC5.5 x 2.1 power cord x1 (0.75 square pure copper wire 50cm)
3. USB to DC2.1 power cord x 1 (Note that you need to use 9-12V for the ATU-100 to start. If you use a mobile power supply or a computer USB port to output power, you cannot start the ATU-100 because their voltage is too low.)
