Voltage Standing Wave Ratio (VSWR)
The VSWR reflects the quality of signal transmission on a line, with ratios under 5:1 considered good for clear communication. If VSWR exceeds 6:1, it indicates issues with the signal path, which may lead to unclear or failed VHF transmissions. Monitoring this ratio helps ensure optimal performance of your radio equipment.
To check your VSWR, from SETTINGS, select DIAGNOSTICS, and then VSWR.
If your VSWR ratio is high and you're experiencing poor VHF transmission quality, check for any wiring faults between the X100 and the VHF antenna. Ensuring solid, intact connections can help improve signal quality.
