It has been asked here a time or two recently what methods can be
utilized to generate custom TLE sets. Some focused on how to
manipulate files while I offer a suggestion for downloading a custom
set tailored to the satellites you seek to observe.
The method I utilize is via the website Space-Track.org. There you
can define favorites lists containing the satellites you desire to
track. From the Favorites list you can then retrieve a custom set of
TLE based on the list you create.
You can create multiple Favorites lists containing satellites that
suit your fancy. I have two lists created; one for inactive
satellites I occasionally monitor and one for active transponder
Visit https://www.space-track.org and follow directions. The site is
fairly straightforward to utilize and works fine in Internet Explorer,
Chrome, and Firefox..
This is a personal issue best discussed with a professional. If you choose
anger I suggest a sledgehammer and a used automobile.
Have a great day!

At my favorite electronics store there are NMEA gps with enclosed antenna
units for sale. Garmin 17N. Check out the web for specs but the lowdown is
they need 12Vdc and report TTL rs232 over a pair of wires. Cost $6 plus
Email me by noon Eastern if you want one. Shipping should be 6-7$$
Back in the early days of PACSATs, I ran SatLink, and somehow acquired
the source code -- which is printed in a stack of paper several inches high.
I would like to electronically archive, and before spending hours at the
scanner, wonder if anyone knows where it may be published? Google
searches lead me to commercial programs, and I've not found at the amsat
web site either.
Thanks & 73,
This email is free from viruses and malware because avast! Antivirus protection is active.
In light of the bi-monthly HEO discussions that pop up here I figured I'd
share some info that many non-US aerospace industry people may not realize.
The International Traffic in Arms Regulations (ITAR) is a set of laws that
those of us in the United States must adhere to, even as volunteers for
AMSAT. I just finished up yet another refresher course from my employer so
this is fresh on the mind.
This email is my own and I don't claim to be 100% to the book accurate,
this is my understanding of it.
Some notes on what it means:
- *Negligence is NOT a waiver for a violation*
- just because you didn't realize you violated it, doesn't mean you
won't/can't be prosecuted
- *Simply inquiring about ITAR related subjects can be a violation*
- If I called a company in Germany about their product I'd like to
use on Fox-1 but need a small modification to the design and suggest the
modification to their product so it works with my design... I could have
*Individual Criminal Violation*
- Up to $1,000,000 fine *per violation*, 10 years in prison, or both.
*Individual Civil Violation*
- Up to $500,000 fine *per violation*
Those are the big hitters so-to-speak. They are also some of the main
reasons we cannot team up with other AMSAT groups to work on projects
together. Plain and simple. Heck, if I was conversing with some of the
Funcube volunteers and helped them with one of their designs via email,
even simple schematic review to help them I could be violating ITAR. So
those of us here volunteering for Fox-1 do our best to operate with these
rules in place and watch the other groups do their own thing.
I work in the launch industry and have quickly realized that the commercial
rocket industry is filled with companies who's satellites cost upwards of
$0.5 to $1 billion each.* To them, a $100 million launch is pocket money as
long as its reliability is high*. Until we see reusable rockets this will
be the playing field in which every AMSAT group in the world has to abide
by. Therefore, cubesats are the ticket into orbit*. On the notion of demo
launches for new rockets such as ones obtained my AMSAT for AO-40... Launch
integrators no longer have trouble finding payloads for them*. There are
more than enough university small sats and cubesats willing to dish out
$100,000+ if not a few million for a ride. Why would an integrator pass up
the opportunity to reclaim a few million $ on the test launch with people
throwing money at them?!
Again all thoughts are my own and would like to state that just because
some people express opinions on this list doesn't mean they are the
opinions/direction of AMSAT. Several posts on here lately have generalized
one or two peoples responses as the direction of AMSAT-NA which is very
much not the case.
I'd like to propose some alternatives to the whiney "I want a HEO" BB emails:
- Write up your vision for how a HEO linear transponder might be
constructed and launched. AMSAT-NA is always looking for articles.
- Share with us your plan for obtaining the funds necessary to launch
a HEO linear transponder
- Publish a paper with your technical design for a next generation HEO
- Designate part of your estate towards the launch funds of a HEO
- Participate in the various AMSAT-related in-person forums worldwide
discussing this issue
- Contribute your engineering expertise to current goals so that
future technologies can be discovered through one of the many ongoing
satellite projects throughout the world
The best part about the above suggestions is all but one require no
money, perfect for most hams who want to complain but never open a
wallet when there is a need. It's also worth noting that you don't
have to be a member of an organization to contribute, though it is
often beneficial in my humble opinion.
Tim; I believe there are two pots each for the azimuth and elevation
meter adjustments. One pair are for the internal meters, the other pair
for 0-5V to be used by the TrakBox (or similar) ADC. Make sure you
turned the correct pair. However first I would make sure the internal
7806 voltage regulator is producing 6 volts and does not oscillate or
have noise on it. Dig out a DVM and scope to make sure. Those
regulators, if not properly bypassed with a capacitor may oscillate.
