ATU-100W

We use the best raw materials. For example, we use T68-2 imported low-heat and low-loss magnetic ring (imported red-brown).
Note: The dark red is a magnetic ring made in China. Buyers please pay attention to distinguish the difference between magnetic rings. C channel capacitors are all 2KV high voltage capacitors. Because we use the best raw materials, we can guarantee that the standing wave ratio will not be very high during use and will be used normally and efficiently during transmission.

NOTE:Recommended maximum power while tuning not above 30 watts. (after tuning you can set 100 watts and work on this power)

Description of firmware program and Accessories:

1.The latest firmware version is 3.2:

(1)SWR greater than 1.1 will automatically activate tuning, and the minimum power has been changed from 5W to 1W. 3.2 Program can be tuned below 5W. However, Too low value may result in insufficiently fine tuning (original default is greater than 5W auto tuning) , please know before placing an order.

(2)Fixed bug with continuous data transfer to the display.

(3)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.

(4)Timeout for display reset increased to 2 seconds. This is required for some OLED displays with a very chain on the reset pin.

2. Accessories:

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.
