Very creative and efficient use of color. Never thought of using the screen
color to match the band. Now I will need a portable heater for the
Minnesota winter...guess I could mount the antennas to an ice house and go
quasi-maritime mobile as soon as the lakes freeze over :)

Hi Trevor,
Just FYI, I've posted a detailed description of how to set up a
station for working the SSB (and also FM) sats on my web page at:
http://kb5wia.blogspot.com/2010/10/satellite-portable-station.html
The station consists of twin Yaesu FT-817ND radios and an Elk antenna,
and a number of us in the community are using such systems for
portable and home ops on SSB sats with very good success.
This article is also in the AMSAT Journal: [David A Palmer, KB5WIA.
"Twins! A Backpack-Portable Full Duples Satellite Station with Dual
FT-817ND's". AMSAT Journal 2011 34:14-16. ], for anyone that's
interested.

We have ARISSat-1. And the ISS. And SO-50. And AO-27. That's four FM birds
workable right now.
Yes - we need more satellite projects launched. But monitoring and working
FM birds
is still a viable part of our hobby! Let;s at least count the nunber
available properly! (grin)

Hi Gordon, MM0YEQ
At the age of 80 (March 15th) I found that comment
very very offensive.
In addition I see that you technically don't know the
advantages of the SSB over FM
Listen here please how looks an SSB QSO via VO-52
made day 28 november 2011 between my self and
IW6OVD and compare with any FM satellite.

Exactly, an O/S thing. Windows (and its predecessor DOS) are case
insensitive for file names. Linux (which I run) is case sensitive -
EOPC.txt and Epoc.txt are two entirely different names - and the program had
an awful time with the apparently missing file. I don't know what would
happen on a Mac, but if you have trouble, that's one place to look.

Hi John,
The UK and the mid-west were mutually visible
in the morning almost the entire month of
November, 1997, via AO-10. There was
a gap for a couple of weeks in December,
1997, but mutual visibility returned for
the 2nd half of January 1998 into
Feburary 1998.
RS12/13 made morning passes visible to
the mid-west roughly every other week
starting October, 1997 to March of
1998. (didn't calculate passes beyond that)
However, if you were tuning around in the FM
mode and found an SSB signal loud enough
to get your attention, I think you probably
heard RS12/13.
Do you remember how long you heard the
signal? (a couple of minutes or a half an
hour or more). Was the signal strength
steady or was there a slow deep QSB?
73, Armando, N8IGJ

Back in late 1997 or early 1998 I was using a Kenwood TR9130 on 2m SSB.
One morning I was tuning from the FM to the SSB portion of the band, and
heard a station just below 146mhz. I tuned them in, and it was a station
from Wales! Obviously going thru a satellite as the 2 meter conditions
weren't that good that morning. I am now wondering what satellite it
probably was. Hearing it was enough to motivate me to eventually get into
satellite operations-that took a few years though.
Anyways, what satellite was I probably hearing? I am guessing AO10 or AO13
but were they operational at that time?

I think that the gallbladder comment was offensive from the perspective that
it
was derogatory. I think it's important for all parts of amateur radio to
understand how other parts view them. That peer "pressure" helps to all have
conversation (when it gets to be a bad view) which can help us arrive at
educating each other about why our views, behavior, equipment, operating
practices etc. are different.
> In addition I see that you technically don't know the
> advantages of the SSB over FM
This is a little on the "assumptive" side of the conversation. He may in fact
completely understand what SSB brings to the table, but also understand, that
practically, FM, WiFi, PSK or any other mode doesn't necessarily "enable"
communications through a satellite as much as it "facilitates" a particular
type
of operating practice, some of which are "easier" to use, than others.
For very short duration conversations, SSB "tuning around" diminishes the
usable
time, because it inhibits communications for the moments that the stations are
"chasing" each other. I.e. you don't know "where" the other station is at on
the dial, and you tune around as they are calling, and then they start tuning
away because no one co be using such limited
resources for. The fact that you are using your native language, might say to
someone who doesn't know the language, that you are trying to "ignore" or
"leave
out" other Amateur operators who you "don't want interfering with your QSO".
That is the same kind of experience that many newer HF spectrum users find on
80m. There are some decade or longer "friends" roundtables on that band, and
many of those conversations are so "specific" and/or so "small in interest"
(health issues) that others operators don't feel like they can join the
conversation. On most of the other bands, conversations are very different in
nature.
I'm not trying to be harsh Domenico. Your contributions in the forum here,
are
always professional and educational. I just want you to have an idea of how
someone else might perceive your intent so that you can see how the original
derogatory comment can become easy to "toss out", in conversation.

I've noticed lately this board is sounding more and more like the boards on
a certain ham radio forum. Filled with personal attacks. Would the things
you say on the internet be something you would say to a persons face? I
think not. I thought we were on this board for one purpose, amateur radio
satellite communications. FM, SSB, CW, packet, it doesn't matter. Making
contacts through a satellite zooming overhead is just a lot of fun. And
when you stop to think about it, pretty darn amazing. Let's get back to
helping one another and making contacts without all the grade school
nonsense.

Well the CB'ers don't have AO-51 anymore so they have to vent someplace.

Hi Gents,
?
I have been working on an excel spreadsheet regarding ARISSat-1, orbital
decay and atmospheric density.
Its a small workbook with some calculations and a? chart.
?
The idea is to work out the volume that ARISSat-1 sweeps through per orbit,
then calculate the mass of atomic material it will colloid with.
Math is NOT my best subject
.
Is there a?math guru on the list willing to take a quick look and tell me if
I am on the right lines.
?
Let me know and I will send it off list.
?
Thanks
