Anybody in this newgroup that has experience of installing a radar
scanner that might not be the one your factory specifies but orf the
same brand, after your original gets busted and the display is in good
condition but out of production ?
Will it work to put a different scanner or do you always have to use
the one the factory specifies ?

You will have to ask the manufacturer what scanners will work with the
display that you have - only they will know what will work (if
anything).

Someone has your scanner sitting in a garage, somewhere, since their
display started smoking and went tits up. Of course, it would help if we
had some MODEL NUMBERS for starters. Might be in someone's garage here or
over on rec.boats.electronics! Ebay is another great place when you want
something.

Within one manufacturer's range there may be some degree of
inter-operability. For instance, many RayMarine domes from the last
10 years are compatible with newer screens with little or no modification.

I have read that the early Raymarine scanners were manufactured by JRC. If
this is the case these might be interchangeable. Also, I have been told by
a JRC rep that the display that came with my 2kw scanner will work with a
4kw scanner so its possible you do not need a scanner of the same kw rating
for your installation.

Interchangeability is built into SOME OEM's designs, BUT if you are
a US Flagged Vessel, that interchangeability NEEDS to be "Type Accepted"
by the FCC when the product is introduced and originally submitted for
Type Acceptance. Any non-Type Accepted arrangment would not be legal to
operate on a US Flagged Vessel. Also non-Type Accepted Radars onboard
non-US flagged Vessels normally are shutdown, at the 3 Mile Limit, just
as all visiting Warships secure all non-navigation emitters at the 3 Mile
Limit.

And do you really think anybody will give a **** if he mates up a scanner
sold for one pleasure boat to a display from a different manufacturer?

Sea lawyers!!!

This attitude is exactly why the FCC has a Type Acceptance on Marine
Electronics. So that idiots like the above, who have absolulty no idea
about the technology they buy, and stick on their boat, don't mess
around with the guts, and cause all kinds of problems for themselves,
and other Mariners. It wasn't to many years ago, that an FCC RADAR
Endorsment was REQUIRED to even take the covers off a Marine Radar.
Missmatching Antennas and Displays from the same OEM may or may not
work even if you do get the wiring correct, but trying it with
units for different OEM's is JUST PLAIN STUPID......

Three issues -
1) the signal that synchronizes head rotation with display rotation.
2) The power requirement of the transmitter at the head.
3) The signal characteristics of the receiver: frequency,
pulse length etc.

I would add a one more.

4. Transmit Trigger Pulse Charactoristics from display to Modulator
