Re: {ΜarineΤraffic:465} Best performance AIS RX

[Hal Mueller]

I've run both a Comar AIS-3R and an Amec Cypho-101, at the same location with the same antenna and feedline. I didn't do precise A/B testing, but my general impression was that the Cypho-101 was pulling in slightly more packets. The Cypho-101 is built like a tank, and gives the impression of more durability. I think the convenience of the Comar SLR 200N (built-in Ethernet) would be a huge win though. I'm running my Cypho-101 through a serial-WiFi converter (Global Cache iTach), and that converter is the weak link: it needs to be reset every few weeks.

Hi Ken
 
Would you expect to get paths out Hawaii way in the future ?

Hello

What would be the best AIS receiver on the market today for a site with high gain antennas 80 meters AGL/ASL? I'm interested in DX, the ability to decode the weakest signals.

Being able to receive long distance signals not only depends on the sensitivity receiver, which is important, antenna height, antenna gain, obstructions between the antenna and the station you are trying to hear. The one thing that is most important is propagation on the frequencies you are trying to listen on. I hear great to the south when the conditions are right. I can't hear a thing to the north because of my surrounding terrain.
My system consists of a COMAR SLR 300N, a Comet GP9 antenna at 32 meters AGL. My elevation is 150 meters ASL.
Under normal conditions my receiving range is between 100 and 200 kilometers. Under ideal conditions the range has been as much as 2900 kilometers.
Here is a screen shot I took a couple of days ago.
