AIS encoding

I am trying to use BASIC Stamp to encode NMEA sentence to AIS format (Automatic Identification System) used in navigation. The structure of the AIVDM message is a variation of the NMEA 0183 sentence format that includes the raw data encoded in a 6-bit format. AIS message looks like this:·" !AIVDM,1,1,,B,19NS7Sp02wo?HETKA2K6mUM20<L=,0*27·" . The idea is to transmit sygnal in NMEA format over the radio , then "translate" to AIS message and display position on the chart plotter on the boat. I hope that someone can help. Thanks, Robert
