Default Need RADAR advice

Bruce,
Thank you, that is the advice I needed. In my previous life, many years ago,
I repaired airborne radars and all the maggies I changed, the frequency
driftted beyond the the ability of the LO to track. In those days, I had at
my disposal a spectrum analyser, which I no longer have. I never saw one
that double pulsed. From your information, it looks like I do not need any
special test equipment, but a dummy load would be nice. I'm not sure
radiating my neihborhood for 24 hours would be appreciated. Are there any
available at reasonable prices that would fit the Furuno slot-line antenna
mount?

To be technically, and legally correct, you should NOT operate a Marine
Radar while on shore, without possessing a Maritime Support Station
License. I wouldn't worry about radiating you neighbors, as the Power
Density of ANY Commercial Marine Xband Radar, 6 Inches in front of the
Slotted Waveguide Antenna, is well below that required to cause ANY
microwave heating, and so far below any Ionization, as to be
inconsequential. When I was doing a lot of radar work, I used a Military
Xband Radar Test Set that included a Xband Load that I adapted to fit
the Standard Furuno T/R Pan Waveguide Connection. One of my old Friends
who is still in the Biz, uses the same setup but feeds the T/R Pan
Output thru a similar connection to a 40ft piece of Xband Waveguide
that goes up a tower at his shop, and then gets feed back into an
modified FR240MkIII Antenna. When I visit him, I know he is in the shop
because I can see the antenna turning from 1/2 mile away. No Turning,
don't bother stopping by, cause no one is home.
