I've probably been aware of these Nav Aids for awhile but never
encounted them until this week in the Puget sound..

I noticed an unusual 'smear' behind the radar return from a channel bouy
(part of the Puget Sound Traffic Control system). At first I was going
to try and tune it out but recognized that this shadow or smear
resembled the old "Boy Scout" Morse Code representation of the letter
"N" "- ." (who says Morse Code is dead).

I'm assuming that this is 10+ yr old technology since my older Furuno
1721 radar wasn't able to detect this NavAid ID while me newer Furuno
1721 mkII does.

Since I was surprised to find a RACON NavAid ID response, I'm wondering
how wide spread it's useage is, or is it another good idea that was
never fully implimented due to USCG budget short falls (like SSID, etc).

I only did a quick look at one Puget Sound chart and " at a glance " I
only saw a half doz. bouys with RACON designation ID..

Since the radar MFGers have now incorporated this capability, I would
hope that more and more Nav Aids would be upgraded to RACON..

My opinion, FWIW.

We have them in the Chesapeake, and have seen them elsewhere on the
east coast too. Mostly in areas with a lot of big ships.

The manual for my JRC radar indicates that if "Interference Rejection"
is turned on, RACONs won't be displayed.

The BC coast has about 20 RACONs. I expect that a RACON is too
expensive to place on every aid to navigation, so they are reserved
for "more important" (to commercial shipping) locations.

hope that more and more Nav Aids would be upgraded to RACON..

There are no modifications needed to a RADAR set to display a RACON
signal - as long as the RACON and RADAR both operate in the same band.

information from a manufacturer of RACONs (and other Aids to

In the past, they only worked on 3cm radar. Not sure if that still
applies in all cases.

I had an old 1720 until 3 years ago that detected racons without
difficulty. They looked like radiating sharp blocks spelling the morse
code ID away from the ATON itself. I wouldn't call them a smear since
they were more sharply defined than any other echoes.

They are implemented widely in the Northeast for important aids,
including bridges in the Hudson River, the Narragansett Bay buoy NB,
the Buzzards Bay towe BB, Cleveland Ledge light CL

I am sure they occur in Long Island Sound as well, but I rarely have
occasion to use the radar there. Also, by the time I get to Maine in
September, the fog is usually gone, so I am not so conscious of them
there.

I don't think there is any need to put them on minor aids. If you have
a radar on, you see them from th eradar reflectors the almost all
carry now, and you know what they are because you know where you are
sort of.

A lot of older Radars can display these.

Indeed, when I bought my large boat and ran it home from Ft. Lauderdale, I
saw one of these near Hawk Channel and it lit up with its ID on the old
Raytheon R21X that was on board.

That was a very, very old scanner and display - but it certainly "painted"
the RACON ID!
