Specification: Charging
port voltage: 5v (USB)
Optimal tuning frequency range: 1.8 -30MHz (maximum available frequency 55MHz, transmission
loss<8dBPower range: 1-18MHz or SSB/CW, 100W; 18-30MHz or FM/AM/FT8, 50W, 30-5MHz pass-through onlyAllowable power supply voltage range: 10- 14.5
V DCMaximum current consumption: 400
mAMaximum working power: 100wMaximum
possible measured power: 150WPower
measurement accuracy: 10%Minimum
installation step of inductance: 0.05 uHMinimum capacitance
installation steps: 10 pFMinimum power required to start tuning: 5W
Minimum possible measured power: 0.1WM easurement step for power up to 10W: 0.1WM easurement step for power higher than 10W: 1WMaximum
installed inductance: 8.53
uHMaximum installed capacity: 1869
pFWorking temperature range: - 20~55
Manual mode: press and hold the TUNE key to trigger the automatic adjustment of the equipment, so as to match the output impedance of the power amplifier (PA) with the antenna feeder.
Automatic mode: no key is required, and the system automatically starts to adjust when it detects that the standing wave ratio is greater than 1:3: 1. (This value can be adjusted) This device is in manual operation mode by default. The starting power threshold is 5W, and the screen is always on. At present, the optional functions include 1-5W startup, 10-second screen self-extinguishing/constant lighting, full automatic/manual mode, etc. The parameters used by the product are the main parameters tested by the developer during the software development process, ensuring the reliability of the equipment operation and use in the basic version. Many parameters can be changed by themselves, but they need to be changed carefully to prevent the equipment from being unavailable.
