Whom are you feeding to that IP?
That’d be @ngtrthanh in northern Vietnam

Thanks.
I’ve seen his website. This one is pretty cool: Map for ADS-B & AIS (hpradar.com)

If you like I can assist to make such funmap your own, just provide your:
prefer lat/long
your own adsb data or adsbhub API or opensky network.
or you can make up your own website to host your station like mine.

Beside my stations and some friends I help to admin, below are some of my experiments
Ship data with 21 fellow feeder plotted on https://aisinfra.hpradar.com
I provide an open API at https://aisinfra.hpradar.com/ships.json
Plotting rather big data as I trying to compete some AIS commercial sites

I have played with the gain and ppm settings of AIS-Catcher using the ShipXplorer AIS Dongle and ShipXplorer AIS antenna and settled for:
-gr TUNER 22.9 RTLAGC off
-p 0
Does anyone know the sensitivity of the ShipXplorer AIS Dongle?
I understand Comar advertises the best sensitivity.
Comar R400N and R500N series: < -112 dBM
QK-A027-plus Sensitivity up to -112 dBm@30% PER
SEANEXX Sensitivity [dBm] RX200 -106
Next month I’ll be integrating a preamp and tuned antenna with ULTRAFLEX 7 cable.

Wow, nice hardware you have @YvesMengin
I use ShipXplorer Dongle, and I get RSSI between -60 dB and -25 dB
Once installed and running… in the meantime:
Looks like more features updated on AIS catcher, Channel, Dark/light toggle & range from station in map using “-N STATION XXX share_loc on LAT xxx LON xxx” in the config file
After my mis-adventure with the vinnant ais antenna and some other stuff I tried out the newest ais-catcher version with my homebrew antenna.
I live close to a lake with a small habour for utitlity vessels and 4 passenger vessels for around 60 to 200 people. The utiltily vessel and one of the passenger boats send a ais signal even when they are moored, the whole year round.
As the summer season has started, I was hoping to catch them doing tours on the lake, but it seems they only switchf on the signal when they are without passenger going to their first stop or returning home from their last?
Not sure what the rules are for them, butI remember one of them sending signals the whole day, Incidently, that was the oldest one, since then they all have been refitted with electrial motors, maybe the ais equipment was changed as well.
This morning I was surprised to see many messenges in the ais-catcher window, which indicated a vessel in motion, but I did not see anything on the lake. Only I after I zoomed out, I found the vessel, an Australian SAR plane.
Not sure what it was doing so far away from home, maybe it has since been sold and still sends out the signal. Unfortunately I was not quick enough to check if I got an adsb-signal as well.
Edit: Maybe it was this one, originally used by AMSA, but then sold on. This in dutch, but I guess google will willingly translate it, in case your are interested.
Austrian perhaps?
(otherwise it’s long way from home 
)

Nah, this is the Australian flag alright 
The AMSA apparently leased two aircraft to a company called EASP Air based in in the Netherlands.
One has been in use all the time, the other, VH-PPG (7C4E12), now PH-EAB (486462), was apparently almost immediately iretired in 2018 and has been recently reactivated.
Today it was flying from Lille to Braunschweig, that is the flight where I picked up the AIS signals.
If you search for PHEAB on FA, you find the this flight, and earlier ones from Lille, the name EAGLE3 and the route looks like some patrol flight over the channel coastline, e.g. Calais.

So as I had a day off from work, I decided to cobble together a DIY Yagi yesterday and go somewhere I knew I would get good reception to try it out. The place I went was 286m above sea level & 23.89miles from the shoreline, I was using the AIS dongle with gain set to 42.1
So I knew it worked based on the above and decided to run it side by side for about 30mins at home, I placed the aerial through a roof and could only get it 3ft lower than the existing DIY Flowerpot antenna. The below are the screen shots at the same time. IP. 231 is the flowerpot existing antenna & IP. 209 is the DIY YAGI
So the results at home look promising with an increase in receiving on a Yagi, so I may end up getting one of these

My station OrangePi Zero 2 + 860t for AIS + SAW TB0436A + DIY flower pot antenna
It is installed on the balcony of a condo (approximately 50m from ground). Therefore, it has a limited overview of the horizon.

Looks pretty good to me.
I’d be happy to transmit into an antenna showing 1.10:1 - as a receiving antenna, I wouldn’t risk making it worse by trying to make it better.

So I found a used 2m band yagi with adjustable elements local on FB Marketplace and have adjusted the elements as per an online Yagi calculator now I can’t verify if its tuned for 162mhz as I don’t own a VNA, but it is currently picking up vessels 40nm out which is the same range as the flowerpot on the roof 26 foot above ground & yagi is 12ft above ground.
