FP/KV1J 3 - 17 July 2018 GN17 Includes Satellite Operation
Eric, KV1J will be active on the Sats from the French island of
Miquelon
from 3 July through 17 July as FP/KV1J. This will be his 12th trip
to the
island. He mostly operate the low bands and 6 meters. When the WX is
good,
he will try to get outside and work the linear birds. Occasionally,
he plans
to also be on the FM birds using a pair of FT-817s and an Arrow
antenna.
Most of the time he will be grid GN17. If he is on the main island
of St
Pierre or if he can borrow a car a drive to Langlade, he will be
GN16. The
island has limited internet. His email is kv1j (at) arrl.net
More information at: http://www.kv1j.com/fp/July18.html

Thanks again to those who helped me to sort out my 5400B rotor issues.
Today I got the station up and running from Lakeville, Pa, FN21. I?ve
already made a number of contacts that verified everything is finally
working as it should. I?m using computer control of a single Arrow antenna
with a 9100. I hope to work as many of the 13 colonies as possible.

Content-Type: text/plain; charset="us-ascii"
I am looking to recruit additional volunteers from the AMSAT community in
North Texas, Central Texas or elsewhere, to help promote "Amateur Radio in
Space" to a large public STEM event. "Moon Day" at the Frontiers of Flight
Museum at Love Field in Dallas Texas on July 21, 2018 is the largest space
themed STEM event in Texas. Last year saw 1500 people attend the 6 hour
event. https://www.flightmuseum.com/moon-day/
Again this year, I am heading an exhibit and satellite demos for AMSAT. We
have a table inside the Museum, (Alongside the Dallas Amateur Radio Club
Table), and a demonstration area outside. I will be setting up the outside
activities and hope to work as many satellite passes as possible during the
10A-4P run of the show.
I am looking for AMSAT people to both help with the inside table and also
with the outside demonstrations. Joe Spier has promised me that he will
send me the FOX "Engineering Model" but I am looking for additional
demonstration aids to illustrate satellite orbits and other aspects of space
communications like various types of antennas.
Being a STEM event, there will be many young people in attendance, (General
public as well as Boy and Girl Scouts), and they get a chance to earn a STEM
patch by answering questions from exhibitors like US. Each year I do this,
I am also surprised by ho many Hams I talk to at the event who are either
inactive or have never experienced Amateur Satellites.
We really need people and content for Moon Day so please consider spending
Saturday, July 21 with us. Contact me off list for more information.

Oh by the way, next year, 2019, is the 50th anniversary of the Apollo 11
moon landing. The Moon Day event is planning a big splash then and it would
be really interesting to see a portable EME station as part of the mix.
That would generate a lot of interest I would suspect. My looking at moon
phase predictions for next year showed that I think they would be favorable.
Keep that in the back of your mind and I will bring it up next year.
Hope to see you at Moon Day, 2018.

Now I see looking at SatPC32 that it shows AO-7 in the 99,625 range in orbit
count. If memory serves me right though, doesn't the TLE orbit count roll
over at 99,999 (Just like a car odometer), so that would mean that we would
be coming up to the 200,000th rev is that right? If I am right, then this
will be coming up in less than a month. Does anybody know exactly when that
will be? I am doing a presentation for a local club and would like to throw
out that fact if I could. Also the day of that event would be good AO-7
operating day I would think.

Tom,
According to the Keps, AO-7 makes 12.54 orbits per day. It will hit 99999
on the 30th or so. You can use the Preview function to find out exactly
when.

12.5?365?45 equals 205,312..5. Based on that you think it had Brolley a
diameter the second time already but it might have been hiring slower when
originally launched.

Tom,
AO-7 was launched on November 14, 1974, that's 15,935 days ago. Multiplying
15,935 by it's current mean motion of 12.53633150 revs/day gets you 199,766
orbits. The orbit number is currently 99,630, so there is a bit of error
there. The mean motion should have very slightly decreased over the past 43
years as the minimal atmospheric drag ever so slightly slows it down.

Paul, N8HM
