I recently pulled this system off
OWTW. Included is everything needed to mount this
radar on a sailboat (Raytheon
mast strut). The interunit cable is 20M long (normal is 15M) and wasn't cut in removing it. Also included are the
power cable and two data
cables (BNC connectors for the display end, spade lugs for the connections to the boat's data bus). It gets better! Also included is a Raytheon/KVH AP-1000
fluxgate sensor which sends
NMEA 0183 HDM sentences back to the radar's
compass port (gives ship's magnetic heading). But that's not all! Also included is a spare R20X display and both displays have fresh "keeper"
batteries for the units' memory. But I'm still not done! Also included is the original
Raytheon R20X manual (no miserable photocopy converted to a PDF!) with fold-out schematics. The AP-1000 "manual" is a PDF hard copy but it's all I could find.
So... scanner,
cables, display(s),
compass,
manuals, and scanner
mast mount. How much? Let's try on $995 for the
gear.
Shipping... truth is, it's not going to be
cheap. The displays and scanner weight about 40-50 lbs before packing. The cables and AP-1000 will probably add another 15 lbs. Toss in packing and boxes and so on, and the total
shipping weight is going to be in the "under 100 lbs" range. In short, if you can get to the Philadelphia area or the
Annapolis area, picking this stuff will be a lot cheaper. Even at today's gas prices.
If it's so great, why am I selling the R20X? Because I have a lust for MARPA support and because the R70+
radar I just installed fits my needs a little better. But for someone who wants a radar for island hopping and for the occasional radar-guided night run, the R20X is still a fine radar.
ADDED:
We bought
OWTW in '93 and the radar went on about a year later at the most. This is a "retired" model (Raymarine's term) and has been for a while (superseded by the "XX" series, the R70/80's , and now the A's, C's, E's, etc.). I replaced the R20X with an R70CRC Plus (same size
screen, same CRT display, but added
SeaTalk and NEMA support plus MARPA) which is also retired.
This R20X package is literally a turnkey setup, reconnect the cables, add 12VDC (and a
boat ) and you're set. There are no chopped cables or any other collateral damage from the
removal. The scanner support strut's in very good shape and there's a dedicated
fluxgate compass for getting the boat's (magnetic) heading. Other than the odd screw here or there, everything that was on the
boat is included (even the strut mounting machine screws - all 12 of them).
The R20X is a good basic radar. The 24 nm range is good for
tracking rain and the like (dodged more than one squall that way!) as well as giving a good picture of what's around the boat on shorter ranges. Tuning, and sea and rain clutter settings are set manually (as opposed to "automagic" tuning, etc.) which many folks view as a plus. What it won't do is chart support, MARPA, pass data to an external plotter, or share data with another display. It will show lat/long, and info on the
current waypoint being used by an
autopilot (via a
NMEA 0183 data link). This is essentially a stand-alone system.
For those thinking "nice package but there's that CRT display...", the CRT draws about the same as the backlighting on an LCD display. The big
power consumers on radars are the transmitter and the
motor to spin the
antenna, something every radar has. Actually, one of the pluses of the X scanners is the
antenna drive is
gear driven instead using a belt drive. The belt drive costs less to build but the gears last longer.
