Hi folks,
Regarding the 10m balloon tracking:
There's some interesting vertical 'Moxon' antenna designs here:-

If you can get hold of a fibreglass pole then it wouldn't be so difficult to
build a vertical - possibly even use wood,

I did some more work tonight on the telemetry data.

Hi Andreas,
You can find one such presentation created by the AMSAT INDIA Team for HAMFEST
India 2011 and the PFD can be downloaded from
http://amsatindia.org//presentations/HFI-2011/ . This contains information on
the below topics.
1. Update on AI projects
2. Real time tracking of satellit
Hi!
Today was a productive day on the radio. I worked two VO-52 passes
in the morning, then SO-50 and AO-27 at midday (one pass on each FM
satellite). K7UGA has now logged 69 satellite QSOs, not bad
considering I could not be on for many daylight passes due to my
day job earlier in the week.
All,
I have been asked to do a presentation at a high-school about satellite
telemetry and LEO amateur satellites and such.
I wonder if there is any material I could use out there such as power points or
so with pretty diagrams and pictures ? Maybe even something
about the latest batch of cubesa
Oops Typo - It was a Ascending pass .

Hi,
Just had an e-mail from the Masat team confirming receipt of my telemetry

Before I started I installed the latest version of Java as recomeneded ( I

I haven't sent any by email, and I'm up over 300. I think they might
literally mean 'includes', not 'comprises exclusively'.
I see that Mark's packets have made it on the map.

All,
well maybe the automatic packet logging is not working after all (at least for
many people).
I've just received another email from the team in hungary, and they told me
that the 'packets received'

It was with a sad heart I learned of his passing. I was fortunate to have

2007. He was quick to smile, always friendly, and eager to help newcomers.
He will be long remembered by many,

Is anyone interested in receiving an unpopulated PC board for automatic Doppler

Please note that all email messages of condolence will be given to Dick's

The mounting pole may contribute some capacitive or inductive loading effects

CB uses vertical beams...the difficulty is that they have to have a non
metallic mounting pole extending into the beam or be end mounted (think

With enough planning I'm sure enough hams could chase something up and
use empty Stationmaster radomes, fiberglass poles or even schedule 80

Indeed, Bruce--this software implementation for the telemetry is awesome!
We'll get these issues sort out. The good news of course is that the
packets are being logged locally, so they can submitted manually via

I wonder if I am incorrect in generalizing my experience. On the
website map, it seems too many people have '0' packets reported. And
my latest pass (some good data at 4 deg. max el.!) isn't reported yet.
When I first ran the application, windows firewall popped up and
asked for me to permit java
Sorry, ignore my post and look at the thread [amsat-bb] MaSat
Telemetry Software.
The "online" indicator has nothing to do with the actual sending of data.
But nevertheless, Mark still shows as 0 packets.

Well, I still don't have it forwarding packets, according to their webpage.
What is the delay from time of packets submitted to posted on the web?
Seconds/minutes/hours?
Looking harder here, but it sure looks like Windows firewall is set to allow
