ATU-130 1.8‑50MHz 200W Micro-Shortwave Automatic Antenna Tuner 10‑15VDC Organic Light Emitting Diode Display.

ATU-130 1.8‑50MHz 200W Micro-Shortwave Automatic Antenna Tuner 10‑15VDC Organic Light Emitting Diode Display. Description

ANTENNA TUNER: Miniature shortwave automatic antenna tuner, without any control operation, suitable for most radio stations.
EXCELLENT PARTS: Adopts C channel 1000V high voltage SMD capacitor, advanced chip and UHF connector to ensure stable performance.
GOOD PERFORMANCE: Higher level capacitance, larger magnetic , thicker wire diameter, greater power bearing capacity, total inductance 12.4uh.
ALUMINUM ALLOY: The shell of the antenna tuner is made of aluminum alloy, with light weight, fast heat dissipation and corrosion resistance.
COMPACT SIZE: The automatic antenna tuner has compact structure, convenient connection, portable design is suitable for home or vehicle use.

Has the function of power meter standing wave meter (according to BYPASS, straight through mode, one horizontal in the middle of the screen, the test value is approximate, and the accuracy is lower than that of professional high accuracy meter, for reference).
PIC18F2520, MCU (faster).
Short wave machine automatic antenna tuner
HF32, 10A, HF33, 5A relays are used.
The maximum measurable value is SSB 275w. It is recommended that the SSB should not exceed 200w for a long .
For other continuous modes, the power shall not be greater than 100W (FT8, CW, FM, when the standing wave deviation is large before adjustment, the power shall be reduced as appropriate, and it is recommended to use 10min interval for 5min).
1.8-50MHz (specifically affected by antenna length and standing wave deviation).
