A coax cable has an inner wire and then the braided shield and a quick and easy way is just to strip the cable back and solder or join using terminal block the Inner wire to the Orange wire and the Outer shield to the Green wire.   However, if you want to make a nicer, more robust solution, you could get one of these…   https://www.adafruit.com/product/2889   and one of these…   https://www.mouser.com/ProductDetail/AIM-Cambridge-Cinch-Connectivity-Solutions/CPMC-88-1?qs=atelM%2FHH1ECgOOZ43uoOSg%3D%3D   Then the Orange wire would go in the + screw terminal and the Green in the – screw terminal. The BNC connector would be crimped on to the coax cableRead More →

Setting up remote access to any network that is operating on a mobile LTE (3G/4G) network is never easy, even for experienced IT engineers. Unfortunately, Digital Yacht just do not have the resources or depth of knowledge to support our customers in doing this on an individual basis. When your remote network is “hidden” inside a mobile network that abstracts all external connections to the internet, the only way to create a VPN is for the 4GConnect/4GXtream to initiate a connection to your VPN server or shared cloud server that does the data routing for you. Our 4GConnect is based on OpenWRT, which supports twoRead More →

The second step is to check your Chart Plotter / VHF Radio settings. The best solution here isRead More →

AIS Transmission/Reception depends on the AIS Class A Class B AIS transponder transmit at 2 watts whereas a Class A Transponder at 12.5 watts. The Class B+ SOTDMA transponder transmits at 5 watts. This difference in power has a huge impact on the transmission range of each transponder.   For a Class B AIS transponder, the transmission range is usually 5 to 7 miles in perfect conditions. This means using a good VHF antenna, placed as high as possible and clear of other antennas. The cables and connectors must also be in good conditions. For a Class B+ 5W SOTDMA, it typically transmits at upRead More →
