Description
Description:
Using PIC18F2520 MCU.
Automatic antenna tuning for shortwave radio, miniature automatic antenna tuner
5-15W tuning
The second version uses an 8-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 150 W , CW, AM, FM 100W
It is recommended to use SSB not more than 120 W 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).
Tuning impedance range: 5Ω～1.2KΩ
Simple instructions:
Connect the power cord 11-14vDC power supply,
Connect the shortwave machine to the IN radio frequency line of the automatic antenna adjustment,
Antenna connects to the antenna ANT (M seat, or quick socket),
Am, fm, cw small power 5-15w tuned (within swr1.5), you can use high power.
Manual mode is required. You can press auto once, and the small dot in the middle of the screen LC disappears, which is manual mode. Press again to switch to automatic mode.
In special cases, press tune to reset, and the LC combination is set to zero.
