This isn't an argument that can have any productive end, and I'm not
going to on about it, but you need to step back, objectively reread
your posts, and then decide if you can reasonably claim *zero*
conjecture. I personally see nearly 100%.

Some yes. But the physical reality of the system he claims to have
cannot work in the differential mode he claims w/o a transponder and
encoder near by. Even if he had such, it likely would not work as there
would be no radar pulses received (from ATC) to trigger it to reply.

completely wrong.

it works exactly as i said it did.

as he said, you need to step back and reread whats been said.

maybe you'll *learn* something about devices you hadn't even heard of a
few days ago.

you're assuming all sorts of things that are simply incorrect, even
though i explained them more than once.

Also the device he has does not mention its own baro altimeter sensor in
its spec.

yet another thing you got wrong.

you looked at a *different* unit, one i never said i had.

the units i have do have a barometric altimeter in them.

you're *so* desperate to bash that you can't even find the specs of the
correct units.

That said, unless you know about the matters being discussed, then
you're not able to judge.

except he's correct. you're not.

Finally, in the areas being discussed where I have in-depth knowledge,
he's always been correct. Sometimes his opinions suck, though.

My experience is that his knowledge is often correct, but it is also
often tinged with BS that reeks of quick research to backup what he
says.

if you ask for proof, you get proof. very simple.

This case, is such and I've outlined it clearly. Especially
points 3 through 5 that I posted outline the most blatant errors in his
decpetion. And his photo proof is laughable for the reasons stated (2).

your points in that post were wrong.

you don't understand how they work and have made all sorts of incorrect
assumptions.

for the zillionth time, they *have* *an* *internal* *barometric*
*altimeter*. no local transponder is needed.

that altimeter is used for several different reasons (which i also
explained).

Expensive, wot.

again, i don't own an atd-300 nor have i ever said i did.

why link to specs of something i don't have???

i said which ones i have more than once and there's all sorts of
information about them out there.

go read the specs of the two units i said i *do* have, and if you'd
been paying *any* attention, you'd know which ones they are, as it's
been mentioned several times. i'm intentionally not saying it again.


Okay then, you're on the path to victory here, and I'll admit that -
once I see your video of it working with proof that it's your unit. So
make the video, get a "catch". Move that camera around. Say something
specific and clearly linked to this group.

Don't do anything to the video.

i'm not on any 'path to victory' nor is this some sort of game i'm
trying to 'win'.

what i wrote is absolutely correct. end of story.

i don't give a **** if you believe it or not.

i own what i said i own, the specs are as i said they are and they work
the way i said they do.

if you actually *used* one rather than *guess* how they work (getting
almost all of it wrong), you'd see that *everything* i've said is
correct.

buy one off ebay and see for yourself.

LOL! OK... I'll bite. What do YOU think that means?

it means he's babbling about the *wrong* *device*.

i don't have an atd-300. i never said i had an atd-300.

I picked that up from Alan Browne and I assumed he was quoting you. My
apologies.

Having searched the thread I now suspect you are using a Zaon MRX plus
another device I cannot identify from the photograph. The MRX manual
can be found at
http://mauldinaviation.com/Documents...nual%202.9.pdf
The manual says on page 12:

"One of the features that makes PCAS superior is the built-in
altimeter, which establishes an accurate base reference for
the relative altitude. Because the altitude information is relative
to your altitude, the unit must know your local altitude
at all times. Under normal conditions, the following occurs:

1Your transponder’s encoder broadcasts your local pressure altitude
(set at 29.92”).
2MRX intercepts and decodes your local altitude.
3MRX compares this to the altitude from the built-in pressure
altimeter to ensure accuracy.
4If acceptable, MRX uses the transponder altitude as a base
reference.
5MRX accurately presents relative altitude information for traffic.

Many times, the local altitude is not available from your
transponder, or cannot be accurately relied on. This is normal
for all collision avoidance, and MRX will automatically provide
a work-around. In these cases, the following occurs:

1MRX uses the built-in pressure altimeter as a base reference.
2MRX accurately presents relative altitude information for
traffic."

So it does seem that nospam knows what he is talking about.

i don't know where he got the idea i had an atd-300.

i specifically said i have an mrx & vrx on more than one occasion.

he's so combative that he doesn't read what's actually written.

Having searched the thread I now suspect you are using a Zaon MRX plus
another device I cannot identify from the photograph.

it's a vrx with its plastic carrying case and inserts.

The MRX manual
can be found at
http://mauldinaviation.com/Documents...nual%202.9.pdf

"One of the features that makes PCAS superior is the built-in

such as when used on the ground, away from planes or airports.

So it does seem that nospam knows what he is talking about.

thank you.

I wanted to know what you expect to see displayed under the conditions
of your quoted passage, and how it is in any way relevant to the points
Alan raised. Hint: it's not.

I thought I would throw a fact or two into what Alan had written. As
it turned out, Alan had got it wrong and I was following his erroneous
trail.

Yes - pretty much what I say above. However, nospam's device does have
its own pressure sensor. In that I was completely wrong.
