[DSP-10] 1st EME2 test -- nil

[Courtney Duncan]

Well, after my first hour-long EME2 test, 886 points, I am 
unambiguously seeing -- nothing.

Which is what I think I expect to see from a single 12 element beam at 6 watts.

Without being able to steer in elevation, I think an hour is about 
all that I will get unless I go crank the fixed elevation up to about 
15 degrees.  Then I could get maybe two hours.

So, here are a few questions:

- Is there a way to save the contents of the Alt-A box, the yellow 
line, and the underlying running averages from session to session? 
If I could load what I have tomorrow and add another ~1000 points, 
maybe I'd eventually see something, but wouldn't want to leave it 
sitting, untouchable all the time between sessions.

- What is the meaning of the dly_emet2r parameter?  Is this 
instrumental delay through a transverter or lock up or something? 
Maybe in my case (DSP-10 to Brickette) it should just be 0?  ... and 
that would presumably make some difference.

Oh, wait a minute, maybe 575 milliseconds is the time after 2.00 
seconds after transmission start before the leading edge of the echo 
begins to arrive back at the antenna.  It's close, according to my 
calculations.  And the software would adjust for variation in actual 
moon distance.  If this is correct, never mind.

- I'm guessing that a station at a KW with four of my 2M12s would 
hear themselves on CW.  That's 28 dB above this.  Does this mean I 
need like 450,000 measurements to see something?  That's a lot, 
hundreds of hours worth!

- Is linear polarization (horizontal) hurting?  What is the return 
polarization on a moon echo.  I know it reverses circular but don't 
know what it does to linear.

Still fun, though.  If it were easy where would be the accomplishment in that?
