Please help me remember how the FT-530 is used for "full duplex" FM sat ops.
Correct me, and add to this list - THANK YOU!
- You must use an earpiece (or a headset) so that the RX audio isn't passed
- There is a keystroke sequence to enable either the LEFT side or the RIGHT
side to be the EARPHONE - what is it?
- Then a press of the PTT "locks in" that audio choice setting, right?
I must be gettin' old ... I *used* to remember this stuff.

It seems to me (presumptuous since my only satellite activity is reading
the group!) that most of the responses suggest causes that would not be
so sharply defined as Bill's observations. He says
Either 0.7 degrees
OR 4-5 degrees
not a continuum of values. I would have to ask if there is any
correlation with day of week, local weather conditions (also a continuum
of values) or AO-7 mode immediately prior to the mode it is in when the
observations are made (IIRC the mode can switch at random).
Can a correlation be made between the elevation at AOS and the signal
level at nearest approach?

Lithium-air battery technology looks to have a big future. With the
potential of providing energy densities up to three times that of the
conventional lithium-ion batteries found in just about every portable
consumer electronics device going around (not to mention the incoming wave
of electric vehicles), many companies, including IBM and General Motors are
pursuing work on lithium-air batteries. Now researchers at MIT have made a
breakthrough that could help make the commercial development of lightweight
rechargeable batteries a reality.

Gary Pearce, KN4AQ recorded the forums last year and made some nice DVDs of
the SDR forums at Dayton last year. I saw him at Raleigh and he is planning
to do the same this year.

Hi Bob,
Will your presentation be available via YouTube or similar? I'm unable to
attend this year due to gardening requirements (85 year-old mother dictated
this), I would very much like to view the SDR presentations.
If homeland security let me come over in 2011 I'll contact you.

Hi All,
Nobody heard the bird in the Memphis area on either pair for the 2226 utc
pass.
Software crash?
Good luck control team,

Sometime this afternoon AO-51 had another software crash. Reloading is
in progress and we may be back up by tomorrow.

I've been away from the birds for a while, and when I checked the HO-68
schedule for this week, there appeared to be no times available with East
Coast/Europe openings. If that's correct, is that the usual case or a
fluke? I'm sure someone has asked the control ops abt. it.
Tnx and 73,

Interesting but this part is troubling me a bit for a space usage "and the
fact that oxygen is freely available in the environment and
doesn?t need to be stored in the battery."!

CryoSat, ESA's ice mission, is scheduled for launch today at 15:57 CEST
(13:57 UTC). Live web streaming starts at 15:35 CEST (13:35 UTC).
CryoSat-2 will be placed into orbit 700 km above the Earth by a Russian
Dnepr rocket launched from the Baikonur Cosmodrome in Kazakhstan. The launch
operator is Kosmotras.
