?While investigating doing mods on existing interfaces, found this
absolutely awesome work done by this guy to improve Signalink USB
interfaces.? He's not doing 9600 baud, but is illuminating.

To All:
I think I have figured out what is going on with the "n's" in the TLEs last
week.
I have a substitution protocol in my process that replaces "+" with " "
(i.e. a blank). For some reason that protocol failed last week and inserted
a "n" instead. I am going to resolve that issue tonight when I create this
week's TLE distribution.
That process has worked flawlessly for twenty some years, but apparently
something has been corrupted???? I will resolve it tonight.
Sorry for the "n" substitution issue, but thanks for the "heads up". I have
been out of pocket this week and just read though my emails.
FYI. Tonight is my 37th Wedding Anniversary Dinner so the TLEs may be a
little late this week. (My wife will want her anniversary dinner, period! In
this she out ranks me.) But I will get it done.

Allen,
Right now it's only AO-92, which is in L/v mode for 24 hours once a week
(currently commanded at 0000UT wed , Tues evening in the US, but you knew
that). I use an Alinco DG-7J for the uplink, and an TF-8900R o down link.
Uplink antenna is a 10 element yagi I got off eBay (link Below). The Alinco
is 1 watt max on 1.2ghz, which according to a few online calculators I'm
getting about 7watts EIRP, which works. Patrick WD9EWR uses essentially the
same set up but has had success with only 300mW.

Message-ID: <00dc01d58567$83ec12f0$8bc438d0$@???????.???>
Content-Type: text/plain; charset="us-ascii"
This weekend is the annual World Scouting "Jamboree on the Air" operating
event. It is the largest annual Scouting activity worldwide. There will be
hundreds of JOTA activations in North America alone, some, like me, will be
helping Scouts make satellite contacts.
If you hear stations on the birds this weekend that are working JOTA, do
make it a point to work them and give them space to work as well. Scouts
find our activities making satellite contacts fascinating and some have
gotten hooked on the hobby through demos and activations like JOTA.
I will be operating with N5EOC (NE Tarrant County ARC club call), at the
Longhorn Council HQ facility in Hurst Texas during the day Saturday the
19th. I am sure besides Scouts coming to visit the event, there will be HQ
staff as well and our operation, including Amateur Satellites, may be the
first exposure to the hobby for some. Same goes for the other JOTA
activations worldwide.
Hope to hear you on the satellites this Saturday for Jamboree on the Air.
Give us a shout.

I could hear them.
Obviously the camera is using an internal mic and not connected to the PA
system at all. I believe previous symposium streams used a phone held in
the hand. At least it is stationary now!
Maybe next time audio can be fed into the camera directly, or at the very
least it will be closer to a speaker.
For the ARISS contact we did a while back we set a laptop on a chair and
used its built in webcam and I wired a Bluetooth speaker into the mixing
board and stuck it next to the laptop's internal mic. It was ugly but it
worked fine.
Perhaps someone can wire a Bluetooth speaker next to the camera/phone for
the symposium.
At a documentary video workshop I did they said audio is the most important
part about video. If you have crappy video you can at least call it
artistic but if you don't have audio you have nothing!
Since then I have always tried to have good audio in all my video. Low/bad
audio is the first sign of amateur video because it's so easy to forget as
you can't tell it is bad at the time, though you can tell if the picture is
bad as soon as you look at the LCD or viewfinder.
