1. Compact appearance, outdoor portable, with housing, rugged and durable
2. With buttons, with 0.91 inch OLED display, resolution of 128x32 pixels, display at a glance
3. This product is both a sky tuner and a power standing wave meter, supporting the display of standing wave value, forward power
4. This circuit contains a set of 7 inductors and 7 capacitors, which makes it can work in a wider frequency range, can effectively cover from 1.8MHz-50MHz amateur radio range
5. Maximum current consumption of 400mA, maximum operating power of 100W, maximum possible measurement power of 150W
Product parameters:
ATU-100 automatic sky tuning DIY open source N7DDC
The finished kit is hand soldered and provides 3.2 program support SSD1306 controller with 128x32 pixels resolution and 0.91 inch diagonal monochrome 0LED display.
This time the circuit contains a set of 7 inductors and 7 capacitors which allows it to operate over a wider range of whisker rates and can effectively cover the amateur radio range from 1.8MHZ- 50MHZ.
Technical characteristics (base model):
Allowable supply voltage range: DC10-15V
Maximum current consumption: 400 mA
Maximum operating power: 100W
Maximum possible power: 150 W
Minimum power required to start tuning: 5 W
Minimum possible measurement power: 0.1 W
Measurement resolution at power up to 10 W: 0.1 W
Measurement resolution for power greater than 10 watts: 1W
Power measurement accuracy error: +10%
Maximum installation inductance: 8.53H inductance
Minimum installation step: 0.05H
Maximum installed capacitance: 1869 pF
Minimum capacitance installed step: 10 pF
Typical consumption: 100-200 mA
Currently optional features are 1w start tuning, 1 second screen self-extinguishing/normal light, fully automatic/manual mode, etc. The default is 1w start tuning, screen constant light, manual/automatic switching mode.
Operating instructions:
DC socket connected to the power supply DC 10-15V positive and negative, the panel POWER switch is in the open position, set the radio power at 5W-10W can, long press the RESET/TUNE button, the sky tuning screen appears TUNE words, at this time the transmitter transmitting sustained power sky tuning can be adjusted automatically. Short press the RESET / TUNE button sky tuning release previously adjusted LC relay, in the straight-through position.
The black and red terminal block is used experimentally for the adjustment of long-line antenna.
Ver1.21 version in the spare position on the motherboard to add SX1308 boost circuit ( this part of the components need to be purchased by the player ), can be reserved through the SMT Hummer plate to achieve the power supply mode switch. And add Auto Full Auto mode interface on the motherboard to facilitate the DIY mill. Note: Because of the noise interference that may arise after adding this DC-DC boost circuit, not as a basis for product quality issues. SX1308 is a fixed frequency, S0T23-6 closed current-mode boost converter, up to 1.2MHZ operating frequency makes the peripheral inductor-capacitor can choose smaller specifications, built-in soft-start function reduces the start-up inrush current. Internal integrated 80 milliohm power MOSFET, the highest boost efficiency up to 97%.

Description:
1. Connect the radio-ATU antenna tuner-antenna
2. When using for the first time, please set the output power of the radio or power amplifier between 20-30W, warning that high power tuning may easily damage the antenna tuner.
3. Set the radio mode, use FM mode
4. Select the antenna band to be used, use 20-30W power in FM mode, press radio PPT, observe the ATU antenna tuner PWR and SWR
5. ATU button TUNE use: short press (less than 1 second) ATU button, in the reset state, long press (more than 1 second) ATU button in the adjustment state
6. If the SWR of ATU antenna tuner in transmission state shows more than 2.0, it means the antenna is detuned. You need to use the antenna 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 antenna will be out of tune. Seriously, it is not recommended to use more than 30W power and should keep the transmitting power below 30W; if the tuning is completed, the SWR shows less than 2.0 and the maximum power of 100W can be used for transmission
