¿É¼ÇÁ¤º¸[(94)A]DC 10-15V Atu-100 Digital Oled Siginal Generator High-frequency Short Wave 1.8mhz-50mhz Radio Communication Station Auto AdjustableProduct selling points:1. Compact appearance, portable outdoors, with a shell, sturdy and durable2. With buttons and a 0.91-inch OLED display screen, with a resolution of 128x32 pixels, the display is clear at a glance3. This product is not only a weather controller, but also a power standing wave meter, supporting the display of standing wave values and forward power4. This circuit contains a group of 7 inductors and 7 capacitors, which enables it to work in a wider frequency range and effectively cover the range of 1.8MHz -50MHz Amateur radio5. The maximum current consumption is 400mA, the maximum working power is 100W, and the maximum possible measured power is 150WProduct parameters:ATU-100 automatic sky tuning DIY open-source N7DDCThe finished product kit is manually welded, providing 3.2 program support for SSD1306 controller, with a resolution of 128x32 pixels and a diagonal 0.91 inch monochrome 0LED display.This circuit contains a group of 7 inductors and 7 capacitors, which enables it to work in a wider range of demand rates, and can effectively cover the range of 1.8MHZ-50MHZ Amateur radio.Technical characteristics (basic model):Permissible power supply voltage range: DC10-15VMaximum current consumption: 400 mAMaximum working power: 100WMaximum possible power: 150WMinimum power required to start tuning: 5WMinimum possible measured power: 0.1WMeasurement of discharge rate up to 10 watt hours: 0.1WMeasurement resolution for power greater than 10 watts: 1WPower measurement accuracy error:+10%Maximum installed inductance: 8.53H inductanceMinimum installation step: 0.05HMaximum installed capacity: 1869 pFMinimum capacitor installation steps: 10 pFTypical consumption: 100-200 mA Attention! The core design data of this Tiandiao comes from the automatic Tiandiao open-source project of its original author N7DDC.At present, there are optional functions such as 1w startup, 1-second screen self extinguishing/constant light, and full automatic/manual mode. The default is 1w startup, screen constant light, and manual/automatic switching mode.Operating instructions:The DC socket is connected to a power supply of 10-15V DC, with positive and negative voltage inside and outside. The panel POWER switch is in the open position, and the radio power is set to 5W-10W. Long press and hold the RESET/TUNE button, and the TUNE word will appear on the sky adjustment screen. At this time, the continuous power of the transmitter can be adjusted automatically. Short press the RESET/TUNE button to release the previously adjusted LC relay, which is in the straight through position.The black and red terminals are experimentally used for adjusting long line antennas.The Ver1.21 version adds an SX1308 boost circuit in the spare position of the motherboard (these components need to be purchased by players themselves), which can be switched between power supply modes through a reserved SMT flash drive. And add an Auto fully automatic mode interface on the motherboard to facilitate DIY grinding. Note: The noise interference that may occur after adding this DC-DC boost circuit is not used as a basis for product quality issues. SX1308 is a fixed frequency, S0T23-6 closed current mode Boost converter. The operating frequency of up to 1.2MHZ allows smaller specifications of the external inductance and capacitance. The built-in soft start function reduces the starting impulse current. Internal integration of 80 milliohm Power MOSFET, the highest boost efficiency can reach 97%.Packaging list:Power meter * 1Line * 1
