Features:
 
Using PIC18F2520 MCU.
Automatic antenna tuning for shortwave radio, miniature automatic antenna tuner
Uses a 4-magnetic ring inductor design, which generates less heat than the original version.
Use HF32, 10A, HF33, 5A relays.
Using 6KV, high-voltage ceramic capacitors.
MAX, SSB 150W, CW, AM, FM 130W
It is recommended to use SSB not more than 150W for a long time.
Small size, 88*150*38mm.
1.9---54MHz (specifically affected by the length of the antenna and the degree of deviation of the standing wave).
