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.
Why is my Vespermarine Marine Radio taking so long to acquire a GPS fix?
If your Vespermarine Marine Radio is taking a long time to acquire a GPS fix, this may take a few minutes. If it is taking a long time check your GPS antenna installation and GPS signal strength using vmAIS.
What to do if Vespermarine Marine Radio shows 'Last position report not sent'?
If the Vespermarine Marine Radio shows 'Last position report not sent', this may happen from time to time in very busy areas with lots of AIS traffic. This is normal behavior for a Class B AIS device.
How long does Vespermarine XB-8000 take to initialize?
Before the Vespermarine Marine Radio can transmit, it needs 1 minute to initialize.
Why is my Vespermarine XB-8000 Marine Radio in silent mode?
If your Vespermarine Marine Radio is in silent mode, check the brown wire has not been accidentally connected to DC negative or vessel ground.
Why can't I transmit my position with Vespermarine XB-8000 Marine Radio (MMSI not programmed)?
You must have a valid MMSI programmed into your Vespermarine Marine Radio before you can transmit your position.
What to do if my Vespermarine Marine Radio shows a built-in integrity test error?
