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.
