Thanks again
Here are some of the coordinates during the errors

S 16.48.152 E 145.42.474

After GPS reset and known correct position.

450M error I think

S16.48.070 E145.43.190
APPROX S16.47.950 E 145.42.460

1.3 KM ERROR!!!!

S16.47.901 E 145.42.885
APPROX S16.47.996 E145.42.996

260 METRES ERROR

The only NMEA I have as far as I know is a GPS output to the VHF radio to give it a position.
I do have a HF radio and that may also have the same but the that radio has not been used for a long time during coastal cruising.
I will put all the wiring back to normal and switch DGPS off but those dogleg errors were there with only the E80 connected to the GPS antenna via the converter and the rest of the seatalk network was isolated and powered seperately.
Hope this helps and will report further when I can get out for a sail after I have done as above.
Thanks again
