I'm trying to home-brew a pair of crossed yagis; one for 2 meters and one for
70cm but I need help with the dimensions.
I want to use folded dipoles for the driven elements.
What size should they be to be resonant at:
1. 145.800 MHz
2. 435.000 MHz

We have all heard that amateurs on the Space Station (ARISS=Amateur
Radio on the International Space Station) frequently have "direct from
orbit" contact with students in schools around the world. To help
prepare the students for an ARISS experience, NASA has generated a
series of teaching modules for the students. They have three different
packages available suitable for students in K-4, 5-8 and 9-12 grades
(for folks outside the US, "K" is Kindergarten at age ~5, and Grades
1-12 are for ages ~6-18). I think that the AMSAT folks should see how
amateur radio can be introduced to children -- the packages are
described and available from NASA's Digital Learning Network (DLN)
<http://dln.nasa.gov/dln/> at
http://dln.nasa.gov/dln/content/catalog/details/?cid=634.
I found them to be very interesting. Perhaps you know some local
teachers who could make use of these lesson plans.
73, Tom

Hi folks:
I would greatly appreciate your help with using SATPC32 for a contact with
the International Space Station this Tuesday. I have been using the program
successfully with satellites, but it does not seem to be tracking the ISS
correctly. When I use SatPC32ISS, I notice that the AOS time is 5 to 10
minutes different from what is reported on the NASA "real time" tracking web
site. Since the ISS has been quiet lately, there seems to be no way for me
to confirm if I'm tracking it OK. I've updated the Keps through the main
program's "Satellites" menu.
I thought that I would have a little more time to work on this, but they
just moved us up in the schedule!
Any advice would be most helpful.

If you have been doing comparisons today, your keps are old. The ISS did a
major reboost early today and that will cause your times to be off. It will
take a bit for the predicts to catch up but you need to have the latest keps
downloaded for the day of the contact.
If you download a new set this weekend, you should see the predicts line up
with the live NASA telemetry.

Went back to attempting to work digital modes on the birds. Hooked a new
Timewave 9600 and was able to communicate immediately by hyperterminal. I
tried a loopback test and couldn't connect to my callsign though the TNC
would light TX. Went to an APRS program, connected the TNC to my Icom and
was able to copy stations. When I would transmit, TNC, radio all keyed up
but I heard no packets on another radio. Just a quick empty carrier.
Borrowed my friends AEA PK 900.same problem.
Never had this problem on past TNC's or laptops. The only difference is
they all had direct serial connections to the laptop. The Dell Inspiron is
about 6 months old and uses the serial to usb connections. I have two
Belkins for the com ports. Are some serial to usb connections problematic
for the TNC? This is the only change I can note since I last worked packet.
APRS and digital modes about a year ago on an older computer with a serial
connector.
Perplexed as I awaited GO-32.

Hi Greg,
sorry for asking but, have you before any experience with 9600 bPs ???
9600 is a direct, pure FSK signal, not AFSK like 1200 bPs in order to hear
"tone-packets".
Therefore, you can not hear anything else than short carrier-bursts
("quick empty carrier" as you correctly pointed out).
So, if you heard just a carrier on another radio, that is 100% normal for
9600 bPs.
I can't see any problem on that.
73, Mak SV1BSX

For years I have used IT as my tracking program with no problems. All of a
sudden I can not longer put the keps in. I have not changed anything on my
computer. I download and save same as I have always done. Now when I try to
put them in it says "can't open file keps.txt" which is how I have always
saved them. Is there someone out there that uses IT and knows computers who
will give me a phone number to call so I can talk to them. Thanks
George,W3VVP

Max,
I was running it at 1200BPS for the tests. I can receive all packets from
APRS on UIVIEW and HyperTerminal. My Kenwood HT call N3MVF-2 can even send
a message to N3MVF on APRS software through the TNC and into the laptop.
With the HT feet away, I cannot connect or ack the message back from the
laptop/TNC. I get on the Icom TX that empty carrier. Same symptom on both
TNCs. In summary, recives, keys TX at TNC and radio but cannot connect loop
test back to mycall/N3MVF on TNC or hear packets transmitted at 1200baud
using APRS.
Good to know abt the 9600 too.
16 years of packet and sat BBS and I'm stumped.
Tnx
Greg

Hi Greg,
sorry for asking but, have you before any experience with 9600 bPs ???
9600 is a direct, pure FSK signal, not AFSK like 1200 bPs in order to hear
"tone-packets".
Therefore, you can not hear anything else than short carrier-bursts
("quick empty carrier" as you correctly pointed out).
So, if you heard just a carrier on another radio, that is 100% normal for
9600 bPs.
I can't see any problem on that.

Hi George, W3VVP
Probably for some unknow reason the directory in wich you actually
save the keplerian elements is not the same that the file IT.ini reads
Open the file IT.ini and find
# Parameters affecting how we read element sets from files...
nasa_checksum_type = 4
check_amsat_checksum = 0
# Uncomment this setting to automatically read in a Keplerian elements file
# (in Update mode) when InstantTrack starts up. Substitute the file name
you
# want it to read, up to 40 characters. If the file isn't found,
# InstantTrack
# will just start up normally.
auto_read_kepsfile = C:\kepler\amsat.txt
If the path in wich you save Keps is not the same that the file IT.ini reads
then you cannot save automatically your keps.
Check if the path are the same and then uncomment the following line
auto_read_kepsfile = C:\kepler\amsat.txt
