Dear Mike,
We have set the delay command successfully.
NIWAKA will send the 5.84GHz at 12:24:30 on 10th Nov. (UTC)
There may be +,-,30 sec error.
Please watch!
Thank you.

Hi Takushi,
Success! I was able to detect NIWAKA. It was lower in frequency that I
expected, but with the Funcube, easy to spot.
The Doppler was huge! and I was moving the dish almost continuous to try and
keep up. I'll edit the I&Q RF file and post it so folks can play it back for
themselves.
Two quick screen shots. In the first shot, you can see the signal on the
left side Doppler shifting down. In the second shot, a close up of one data
burst with Doppler - about 3 secs or so...

The 5.84 GHz transmitter seemed to come on very close to the set time. First
detection at 12:24:21 UTC.
More later.

Congrats, Mike! That's a nice result.
Do you have details of your downconverter/receive/antenna system posted
online?

Hi Mark,
Very simple system. I was not trying to capture the pictures, but merely
detect the signal. So I used my terrestrial 5.760 DEMI transverter. Measured
it on the bench at 5.84 GHz, it was down about 15 dB from 5.76 G.... The
transverter uses a 144 MHz IF, so simply used my Funcube set to 224 MHz.
The dish is 2' with a Directive Systems 5.76 G feed horizontally polarized.
I calibrated Azimuth using Sun Alignment yesterday and left the tripod set
up over night. The little green object on top is a digital inclinometer.
Netbook is running HDSDR for the FunCube.

setup.jpg
Real crude, but worked. I'd like to dig up a 5.84 G preamp.....
Mike

Here are two I&Q RF wave files that can be played back in programs like
HDSDR. They are the full 96 kHz bandwidth.
The first file is about 18 MB and is the first detection of NIWAKA.
The second file is 3 MB and shows the Doppler near the end of the 2 minute
window. The 5.84 GHz signal Doppler shifted ~ 125 kHz in the 2 minutes I was
watching it. I had a tough time keeping up. This was faster than I
experienced running 24 GHz on AO-40!
