[Moon-net] 10GHz Polarization

[OK1DFC]

Hi all,
really strange discuss here now and open again same problem like many times
before. I am not on 10 GHz QRV but fact is that CP is much better for Moon
bouncing like linear polarization. This is physical fact and no possible to
change it by the discuss only because "PHYSIC is no possible to bend".
I saw couple items before that the discuss about physical fact is moving
some where to emotion base or so.
With the could head I would like to present that:
As a first: No possible to discuss or present result of EME conference 2002
in Praha as any dictate or so, because the result of recommendation to use
CP was as a result of open, public discussion and voting all attending
persons, no dictate of any single person.
As a second: Presenting two gurus of MW Moon bouncing as a main argument for
using Linear polarization is unfair. Both guys like W5LUA and WA7CJO are top
in the MW operation, but if you check their systems, they have profi feed
horns and dishes where is not so many space for laboration or changing of
possibility to work CP. If I will have on my garden profi dish and profi
linear system do not thing to start dismantling this as a first. I am fully
respecting Al and Joe and their great job, do not thing that I am fighting
them.
If any body want to present any advantages or desadvantages between CP and
Linear polarization, please made 100 measuring experiments and present here
your results with clear solution for all of us.
Thanks

Hi
Just a short comment:

F2TU statement!
- For contest ARRL, the propagation was very bad (East F and LX). We
carried out tests with LX1DB. I am in VP. LX1DB tested LP and CP: my
signal was received more clearly in CP.
That is a fact.
Just to clarify the WX was 8/8 covered with stratus clouds and my echoes

not stable at all. After the QSO with F2TU I change to CP.
Result: after 10 min time to change the feed my echoes always stable and
more clear audio!
I just checked the other station at that time on the band and there the
audio was also clear and easy to read even in small audio bandwidth.
I had not more time because I was QRL service on Sunday
-Remember the comments during the LIN CP test.. the signal was more easy
to read. I think it was GW4?
My way to goes is: I try analyzing the result and making the effort to
realize.

Folks,

Since yesterday I've received
too many emails about this issue.

I want one thing to become clear.

The signals processed were received at
the following stations:
F2TU, G4NNS, LX1DB, OK1KIR and GW4DGU.
I only processed the data that was sent to me via
web or CD (and no data from my own station was
analyzed this time).

The two plots circulated today were from a big station
to a small station and shows -10dB when cross polarized.
the other was from two small stations and shows -6 to -8dB
when cross pol.

These are FACTS, if for some reason you don't trust or
want to analyze the data yourself I will be glad to send it
over (it should fit a CD or two).

This humble servant only processed what was sent to him,
I know it was customary in the middle ages to kill the messenger
of bad news, please drop that tradition will you !!!

Luis Cupido.
CT1DMK.


P.S. I would be active no matter it is on Lin or CP
but I would like to know what I should make for my new
setup that I'm building right now with a bigger tube and a
new preamp.
