I realize this is a long shot, but does anyone have experience with the
Raytheon NMEA/SeaTalk bridge? I have an older one (4 years) that I'd
never used until recently when I bought a new Icom 502 and then I wired
in the bridge into my SeaTalk bus to transmit lat/lon info to the new
radio. When I first fire up the Autohelm GPS and the radio, it gets the
signal and the radio reads out the correct info, but after about 5
minutes of operation the radio data starts flashing and pretty soon it
reads "no data available." Because the bridge is solid state it's hard
to imagine that it works for a few minutes and then fails -- is this
possible? The bridge is wired into the bus in parallel with my
autopilot, and everything else on the bus is working perfectly. I want
to be sure the bridge is defective before I spend the $$$ to buy another
one; if it weren't for having to hook up another external antenna, it
would be cheaper to buy an inexpensive Garmin than to buy another bridge.
