Dear Kevin,
We plan to flash the LEDs on Christmas Eve. So we will start testing around the end of this month.

When is the LED MORSE supposed to happen?

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.

Hi Takushi,
Excellent! I'm set and waiting for NIWAKA to come up over the
horizon in
about an hour.

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,
I loaded the latest keps today and the pass times are confirmed.
Looking
forward to hearing NIWAKA!
I will be recording the pass using a FunCube Dongle in I & Q RF
mode,
so
I'll have ~ 80 kHz of bandwidth. If I'm able to detect the
signal on
10 Nov,
I can try an RTL SDR receiver on 11 Nov that can receive a much
wider
bandwidth. I use HDSDR with both SDR receivers.
I will be setting up portable in a nearby parking lot so I have
an
unobstructed view to the satellite. I see the Doppler will be
quite
large on
both days (~ 125 kHz). I use the original NOVA program on my
laptop in
the
field which calculates Doppler for me.
Let's hope for success and thanks for coordinating this test.

Dear Mike,
We found the south paths with enough elevation in your
suggestions.
We plan the following times which start 5.8GHz transmission. The signal continues around 2 min. (1) at 12:24:30 on 10th Nov. (UTC) (2) at 11:32:30 on 11th Nov. (UTC) According to our calculating orbit software, the time is little bit delayed. Please confirm with the latest TLE. Thank you.
