Hi everyone.  I first searched the entire AIS for something similar to my issues, and finding nothing identical I am looking for some enlightenment.   I recently had an authorized Raymarine Tech install an AIS 650 alongside my E120 MFD and going out through a Digital 4.5 db 4' antenna.  Cruising the boat last weekend in the San Juans, I noted that I could see all information for Class A's (tugs, Ferry's, etc), yet could not see the names on any class "B"s.  I docked at Friday Harbor and, using Marine Traffic.com, I could see my boat--Identified by name and data--while sitting there.   Upon getting back underway, I was told by other boats that they could not see my name or much other data on their receivers.  Again, I could still see Class A targets, to include their names and all data, but could not see the same info for any Class B target.   So, it appears that I am losing my ID while underway, and  my unit is not ID'g Class B's.   The one solution that I see offered on most of the AIS issues  on this forum appears to be making sure that the software version is the most current.  I bought the unit from an online retailer, had them input my boat info, and then had a local tech do the install.  I am not sure what version I have on the unit (I am in So Cal, boat is in Washington).  Any ideas as to what my prob sounds like?Thanks, MikeSee More
