On Saturday I connected the radar directly from the core electronics to both E120W MFD's (one at a time of course). The bizarre thing is that it did help to do it that way, in fact on one attempt the radar worked for an HOUR.

(not the first attempt, mind you....otherwise I would have proclaimed it "fixed" at last...but I knew eventually it would fail again from previous efforts where it ran perhaps 10 minutes or less...was just amazed it worked fine for an hour before restorting back to bad as ever)

But alas, in the end, it resorted back to "Antenna not rotating" error happening within seconds of pressing "TX".

Raymarine tech now thinks heading flash sensor or gear box is on the way out. Only way to know and fix is send it BACK to Raymarine AGAIN...but this time send the entire 50 lbs of pedestal, not just the core.

A summary so far shows at least 3 different problems-

1. Broken data wire caused original "Data not Found" issue
2. Bad no. 1 port at SeaTalk may also have contributed to "Data not Found"
3. Bad something else causing "Antenna not rotating" issue

And this on a system only 4 years old with radar used probably 2 or 3 hours at the most and pristine inside the pedestal...zero corrosion. Amazing.

=================

As an aside, it actually didn't make any difference on the straight versus crossover coupler. I bought both and used both....made no difference !
