Wanting to upgrade my ham computer from XP/P4 to something newer and faster.
Have
used Nova, AEA ST-1, and Yaesu G-5500 for ever. Have a nice HP quad core
machine
with W7, that I cannot get to work with the ST-1, says cannot initialize port.
Tried a couple of other units with same results, so I suspect it has
something to
do with the newer parallel ports.
So what am I missing ???
I would prefer to use a USB port of course, but cannot find any controllers
now
that are ready to go, or will work with Nova. I am trying to stay with Nova
and
the Yaesu G-5500
What is everyone else using these days?

SatPC32, and a LVB tracker running off a USB to serial adapter, works very
well, and you'll pick up many features in the new software.

AMSAT-NA, AMSAT-DL, and Virginia Tech Announce Potential Phase-3E
Opportunity
Virginia Tech has approached the US Government to fly the Phase 3-E
space frame into High Earth Orbit (HEO) in order to support
scientific payloads as well as serve as an amateur radio satellite.
During the AMSAT-DL Annual Meeting on 4 JUL 15, the AMSAT-DL
membership approved the concept, agreeing to allow the Phase 3-E
space frame that is currently stored in Germany to be shipped to
Virginia Tech in the USA for further construction, testing and
preparation for eventual launch to HEO should the US Government
formally agree to fund such a mission.
Should the project move forward, AMSAT-NA will apply for frequency
coordination from the IARU Satellite Advisor and satellite licensing
from the FCC as the satellite's initial operator.
Stay tuned to the AMSAT-DL Journal, the AMSAT-NA Journal, and the
AMSAT-NA News Service for further developments and details as they
become known.

Request for help with SPROUT Telemetry Collection
Students from Japan's Nihon University are requesting help gathering
telemetry from the SPROUT satellite
SPROUT was launched at May 24, 2014 from Tanegashima Space Center in
Japan.
There are 3 main missions in SPROUT.
?Deployment demonstration of inflatable membrane structure.
?Demonstration of attitude determination and control technology for
several kilogram class nano-satellite.
?Upbringing of human resources of a space sector

QIKCOM-2 Satellite messages
In a message to the AMSAT-BB on July 22 Bob Bruninga WB4APR, invites
proposed standard messages for the next APRS Satellite:
Bob writes, "Our next QIKCOM-2 APRS satellite will accept 2 digit
uplink DTMF messages to be spoken on the downlink. We have already
programmed all of the ARRL standard radio grams and emergency
messages.
But there is room for more. So think.... What kind of message
would you want to send (that is not included in the existing ones)
from your HT out in the wilderness. At a hamfest? or any other HAM
Radio event or opportunity. Keep them simple and of the same order
of length as the existing ones.
The existing ones are listed here: http://nts.ema.arrl.org/node/30
But the implementation cannot include blanks for fill-in like the
regular ones. But any sentence that stands alone can work.
Just thought I'd open it up. Plenty of RAM and only 1 week before
delivery...
Serious considerations only."
To clarify some thought processess Bob added in a subsequent follow-
up,
"Well, took a few moments and here are some of my ideas. I just
realized I can allow a single digit modifier, so the digit can go
from 0 to 8.
Demonstrating APRStt at Hamfest
Demonstrating APRStt to friends
I am on schedule.
I may be delayed N hours
I may be delayed N days
I may be early N hours
I May be early N days
I may quit early N stops
I may go farther N stops
We are camping and enjoying it greatly.
We are hiking and enjoying it greatly.
We are sailing and enjoying it greatly
Call me on my cell
Call my cell on the hour.
Or there can maybe be 1-to-8 different whole word modifiers too.
Like:
Please Send ___ (Money, food, water, supplies, shoes, sleeping bag,
blanket,fuel)
We are operating on ___ power (Solar, wind, battery, generator,
emergency)
We are staying with ____ (Mom, dad, sister, brother, uncle,
aunt,friends)
Please pass to ____ (Mom, dad, sister, brother, uncle, aunt,friends)

are seeing it from space?
2. What do you think about the plans of some multi-billion dollar
investors to mine raw materials on asteroids and satellites?
3. If you were in an emergency situation inside the ISS where an
ammonia leak is quite high and the hatches don't work, what
would you propose as escape route to save you and your team,
and why?
4. What is the most interesting experiment to perform, and why?
5. Do you see the speed of space travel progressing much further
than the point it's at now (within our own solar system)?
6. When you return to Earth what do you think you will miss most
about the Space Station?
7. What are your expectations of the manned trip to Mars?
8. Isn't the NanoRacks deployer a cool temperature when it's
actually working?
9. How do you maintain a natural sleep pattern aboard the ISS?
10. What were the steps you took to become an astronaut? Do you
have any advice for those of us who wish to go into space?
11. What do you think the biggest challenge to the space industry
today, besides budget?
12. In terms of hardware, if you could have one thing installed on
the ISS, what would it be?
13. What went through your mind while listening to the final
countdown before lift-off?
14. How does the ISS keep away from space junk?
15. What are the first effects that you feel in zero gravity?
16. What was a favorite experience of yours while in space school?
17. How many meals do you eat in a day, and has your appetite
changed at all?
18. Is moving around in microgravity conditions always fun, or does
it get uncomfortable and annoying?
19. What do you think the most important decision you made that put
you on the path to becoming an astronaut?
20. Have you ever seen anything weird in space you couldn't explain?
21. What planet would you like to investigate more, aside from Mars?

Satellite Shorts From All Over
+ On July 22, 1962 the first live public trans-Atlantic TV broadcast
was relayed by Telstar 1, a communications satellite that had been
launched two weeks earlier. The broadcast featured CBS's Walter
Cronkite and NBC's Chet Huntley in New York and the BBC's Richard
Dimbleby in Brussels. Later that same day the satellite relayed the
first telephone call to be transmitted through space. Although it is
no longer fully functional, Telstar 1 is still in orbit around
Earth.

Upcoming ARISS Contact Schedule
United Space School, Seabrook, TX 12:52 UTC July 28
An International Space Station school contact has been planned with
participants at United Space School, Seabrook, TX on 28 July. The
event is scheduled to begin at approximately 12:52 UTC. It is
recommended that you start listening approximately 10 minutes before
this time.The duration of the contact is approximately 9 minutes and
30 seconds. The contact will be a telebridge between NA1SS and W6SRJ.
The scheduled astronaut is Kimiya Yui KG5BPH
The contact should be audible over the west coast of the U.S.
Interested parties are invited to listen in on the 145.80 MHz
downlink. The contact is expected to be conducted in English.
The United Space School is the premier educational program hosted by
the Foundation for International Space Education (FISE). For two
weeks each summer, FISE invites approximately 50 students from 23
different countries to the Clear Lake, Texas area to introduce them
to aspects of working in the space sciences. During their stay, the
students work together in teams to assemble a manned mission to Mars,
utilizing knowledge gained from guest lecturers and interactive field
trips. The Foundation for International Space Education Board of
Directors has two head teachers and five team mentors to assist the
students in their day-to-day activities. United Space School
culminates in a project presentation, in which the students present
their final project to a panel of industry experts and the public.
Upon successful completion of their final project presentation, the
students are awarded a graduation certificate.
Participants will ask as many of the following questions as time
allows:
1. How has your understanding of the universe changed now that you
are seeing it from space?
2. What do you think about the plans of some multi-billion dollar
investors to mine raw materials on asteroids and satellites?
3. If you were in an emergency situation inside the ISS where an
ammonia leak is quite high and the hatches don't work, what
would you propose as escape route to save you and your team,
and why?
4. What is the most interesting experiment to perform, and why?
5. Do you see the speed of space travel progressing much further
than the point it's at now (within our own solar system)?
6. When you return to Earth what do you think you will miss most
about the Space Station?
7. What are your expectations of the manned trip to Mars?
8. Isn't the NanoRacks deployer a cool temperature when it's
actually working?
9. How do you maintain a natural sleep pattern aboard the ISS?
10. What were the steps you took to become an astronaut? Do you
have any advice for those of us who wish to go into space?
11. What do you think the biggest challenge to the space industry
today, besides budget?
12. In terms of hardware, if you could have one thing installed on
the ISS, what would it be?
13. What went through your mind while listening to the final
countdown before lift-off?
14. How does the ISS keep away from space junk?
15. What are the first effects that you feel in zero gravity?
16. What was a favorite experience of yours while in space school?
17. How many meals do you eat in a day, and has your appetite
changed at all?
18. Is moving around in microgravity conditions always fun, or does
it get uncomfortable and annoying?
19. What do you think the most important decision you made that put
you on the path to becoming an astronaut?
20. Have you ever seen anything weird in space you couldn't explain?
21. What planet would you like to investigate more, aside from Mars?

Satellite Shorts From All Over
+ On July 22, 1962 the first live public trans-Atlantic TV broadcast
was relayed by Telstar 1, a communications satellite that had been
launched two weeks earlier. The broadcast featured CBS's Walter
Cronkite and NBC's Chet Huntley in New York and the BBC's Richard
Dimbleby in Brussels. Later that same day the satellite relayed the
first telephone call to be transmitted through space. Although it is
no longer fully functional, Telstar 1 is still in orbit around
Earth.

Can someone explain to me why it is a bad thing for the satellite to have
too much uplink power to it?
Even if you send a huge amount of power up, I don't see how it could damage
the satellite, by the time it reaches the sat, the power would be so low.
Is this only something for the linear birds, does it apply to FM satellites
as well?
Thanks

Hi Skyler,
There are two issues:
The first issue is the automatic gain control in the satellite
passband. Linear transponders only have a limited amount of power
available to spread across the 20 kHz - 100 kHz passband, so the gain
needs to be limited to keep the transponder output linear. When a very
strong signal is in the passband, everyone else's signal is weaker.
For example, I can usually receive my own signal (using 5 watts from
an FT-817 to an Arrow) about S8 above 5-10 degrees on FO-29. On Field
Day, it was tough to get a decent signal even above 40 or 50 degrees
because of all the high power stations in the passband. Your signal
should be no stronger than the beacon.
The second issue is how it could damage the satellite. The issue is
when an aging satellite's power system (such as AO-7 or FO-29) can't
manage to provide the full power ordinarily needed to run the
satellite. In AO-7's case, too strong of a signal can bring the
voltages available to the transponder down to a point where it can
cause the satellite to switch modes. In FO-29's case, strong signals
in the passband while the satellite is in eclipse could cause the
battery voltages to drop to a point where the satellite would shut off
to preserve the batteries.
This doesn't apply to FM satellites, but using a lot of power to
dominate the satellite by using the FM capture effect to keep weaker
signals out is considered poor practice.
Remember that the FCC amateur service regulations require the use of
the minimum power necessary to conduct communications. The regulations
also require you to not cause harmful interference to other amateur
stations. Using excessive power on a linear transponder violates both
of those provisions.
Also remember that when we're talking about "excessive power" that's
ERP, not actual output. Even 500 mW could be excessive power if you're
using a huge antenna array and the satellite is right overhead. I have
heard stations use the excuse that they are only running 2 watts when
called out for pounding the transponder with an excessively strong
signal. Well that might be too much, turn it down more. If your radio
doesn't allow you to turn the power any lower, you may need to add an
attenuator pad to your station.
Also, a CW signal is much harder on a linear transponder than an SSB
signal because a CW signal at keydown is full power, where a SSB
signal only reaches full power on voice peaks.

Thanks for taking the time to answer, that makes sense.
I only have FM capability currently, but that is good to know for when I
get to SSB.
