OLED mini standing wave meter hardware, using 2.23 inch 128*32 resolution orange OLED screen as display, by AVR's mega32 as MCU, built-in capacity 350 mA 8.4V Li-polymer battery, 5V (micro usb) charging, standing wave detection part is using the triple magnetic ring detection circuit, M-type (SL16) connector, size: L 118.5mm*W35mm*H26mm (maximum size).

OLED mini standing wave meter software, software for diode non-linearity of 1024 points interpolation algorithm correction, and has a simultaneous display of standing wave, peak forward power PF, peak reverse power PR, average forward power AF, average reverse power AR. use frequency: 1.6MHz-30MHz, maximum measurement power 100W.

Usage:

The left-hand side of the VSWR meter is the input side (connected to the radio) and the right-hand side is the output side (connected to the antenna). Toggle the power switch on the right side of the VSWR meter, the VSWR meter will first display the world map, then the version number and battery power (only the reference power value), then enter the main measurement interface, at this time there is a signal will display the standing wave and the corresponding power value.

The charging LED indicates that it is always on during charging and goes off afterwards. When there is input overvoltage, output undervoltage and overvoltage, output short circuit, charging time out situation, flashing at 1.6Hz.
