I have had some luck sending inquiries to Furuno USA (who sent query to East Asia). http://www.furunousa.com/Support/Default.aspx
Last time I sent a query, It was for a Furano GPS receiver used in an integrated timing receiver/outdoor antenna. Received original Japanese spec sheet with some broken English translations. Fortunately, schematic was included. greg w9gb Sent from iPad Air _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
