How to check antenna VSWR on Vespermarine XB-8000?
If the Vespermarine Marine Radio antenna VSWR is high, you should check your antenna installation. Use the VSWR meter in the vmAIS status page. A poorly tuned antenna, bad cabling, or connections are typical reasons for a high VSWR.
What to do if background noise level on Vespermarine Marine Radio AIS receiver channel is high?
To address a high background noise level on the AIS receiver channel of your Vespermarine Marine Radio, first determine the channel and frequency using the vmAIS status page. Look for an RSSI level greater than -77dBm. Then, remove any sources of noise onboard at this frequency.
