Upcoming ARISS Contact Schedule as of 2015-12-30 21:00 UTC
Quick list of scheduled contacts and events:
Frederick W. Harnett Middle School, Blackstone, Massachusetts, telebridge
via K6DUE
The ISS callsign is presently scheduled to be NA1SS
The scheduled astronaut is Timothy Peake KG5BVI
Contact is a go for: Tue 2016-01-05 17:42:06 UTC 81 deg
Sandringham School, St. Albans, Hertfordshire, UK, direct via GB1SAN

****************************************************************************

I would like to thank everyone who has supported ARISS since the first
contact back 15 years ago. I can still remember ARISS contact #1 where I was
the control operator at Burbank outside of Chicago. It has been a blast
ever since.
Now we are heading into 2016 where we hope to keep the traditions going.
We have 2 contacts scheduled in the first week of the new year.

Message-ID: <5684B590.9060604@xxxxxxx.xxx>
Content-Type: text/plain; charset=utf-8; format=flowed
I use an IOS satellite tracking program called SatExpPro which downloads
the TLE's from Celestrak. I can't find the TLE's for AO-85 at the
Celestrak site. Does the Celestrak site use a different name for
AO-85? There is no listing for Fox either. The SatExpPro program does
not allow for the downloading of the TLE's from the AMSAT site which has
the TLE's for AO-85.
I use SatPC32 on my desktop and download the TLE's from the AMSAT site
for AO-85. Is there a reason that the Celestrak site would not host the
TLE's for AO-85?
Thanks for any help in solving this mystery.

I use the same iPhone app, Frank. It's a shame that they don't include
those newer sats.
I've put an icon on my screen to the following URL to at least have a way to
see pass predictions for those satellites even though it's not as easy to
use as the SatExpPro app:

It is true, having been launched on a classified mission the TLEs for
AO-85 are only available to a few of us at AMSAT. So the AMSAT-provided
Keplerian elements are the only ones that contain them.

Hi James,
I have used an Avenger PLL321S-2 LNB. This has good gain in the in the
10GHz band (although probably a bit less than in the 11GHz). With it
I've been able to receive my local terrestrial beacon without using a
dish. The beacon is 200mW, about 40km away and not line of sight, so I
think that the receiving performance is OK for many ham applications.
The main problem is that the local oscillator in the LNB is not very
stable. If you're using it for a narrow-band application, it will drift
quite a bit.
I think that the situation (regarding gain in 10GHz and oscillator
stability) is similar with all the satellite TV LNB's. Some people have
done modifications to the LNB to improve the stability. The most popular
are:
* To use an external PLL driven by a TCXO or OCXO.
* To generate a strong carrier in the 10GHz band, to receive the carrier
and the signal of interest with the LNB, and to use the carrier to mix
the signal of interest down to, say 28MHz. Since the carrier and the
signal are both affected to the same extent by the LNB LO drift, this
cancels most of the drift.
Regarding sats in the 10GHz, I don't know of any which is working right
now. If I recall correctly, the two future geostationary sats will have
10GHz downlinks. However, if you just want to play a bit, there are many
geostationary which transmit narrowband data streams on the 11GHz band,
so you could use this to test your setup.

Hi Daniel,
Apologies for a shameless New Year's plug but the two latest editions of
Oscar News, # 211 and 212, both carry articles about successfully using
these low cost devices. http://amsat-uk.org/tag/oscar-news/ You can join
AMSAT-UK online and then easily download the magazines.
These devices should also be ideal for receiving signals from the
Geostationary Eshailsat transponder.

Sort of off the AMSAT topic, but the most recent estimate is that about 20
gigawatts of solar will be added in 2016 -- almost doubling the total
installed capacity of US solar power. This is being primarily driven by
residential installations. Utility-scale installations are actually down
5%.
One thing that was keeping mass market efficiency down was a glut of
production capability that existed through 2014. Manufactures were not
keen on investing in new processes at the same time they were going out of
business or consolidating. That glut has been drying up, prompting Elon
Musk's to build a $1 billion dollar factory in Buffalo NY which will
produce 1 GW of panels annually by the end of 2016. Those panels are
expected to be 22.1% efficient. That's a pretty impressive gain in
efficiency.
Often times market conditions, not technology, dictates what reaches the
mass market, and that has most certainly been the case in the solar
industry. That 50% increase in panel efficiency doesn't necessarily mean
that the cost per watt will be reduced in the short term -- those panels
may simply sell for 50% more.

Subject: [amsat-bb] Sat32PC talking to radios question

I recently installed the Sat32PC program and it doesn't look like the
program is talking with the radios.
I am using an IC-7000 and a FT-100D as the two radios.
I have set up both radio's comport information and at this point I do not
have a rotor.
I see that SatPC32 is tracking as the frequency changes, however, the radios
aren't doing anything.
What am I missing?
Thank you
