Subject: [amsat-bb] Worldwide Linking
An inquiry during my EchoLink presentation last night ...
"Clint, we know the orbit of a specific satellite, we know its projected
footprint, and we know its expected time over that footprint. Now if we had
"X" amount of ham stations, RF equipped to talk with this satellite, and
these hams were also equipped to communicate via VOIP EchoLink or IRLP and
enough of these stations were lined up around the world within the orbital
path, we would have continuous 24 hour, 7 day a week coverage around the
world with this bird.
"The EchoLink or IRLP stations would all be tied together via connection to
a main conference server such as *SCARS*. This would mean that anyone
worldwide could access the satellite day or night by transmitting and
listening to the earth station that was in the footprint at that particular
time.
"I would see some things needing to be understood by the users, such as
timing in regards to internet latency, repeater and or link delays, and the
need to understand a pause would be necessary before transmitting, etc. ....
"
I have thought of this on a much smaller scale ... I welcome your comments.
I do not want to completely discourage this gentleman from "thinking
globally" (grin).

When I was an Air Force pilot, and the XYL would go on a trip, I'd hit as
many bars and carouse as much as the law would allow (remember those days
Leo?). What do I do now?..Grid-pedition! I'll be taking a trip to the
middle-of-nowhere Nevada on October 17th to the boundary of grids DN00 and
DN01 so you can cross them off your grid maps. Look for me on the AO27 pass
around 2054Z. Give me a call, and give my 5 watts and ARROW a break. No
QSL or SASE required, just a quick e-mail note to check my log and QSLs will
be in the mail to you.

I found this article in the last issue of Air Force Magazine to be
interesting:
Game Changers
"System F6 is designed to help break the paradigm of monolithic satellite
design-that is, planning to put all of a satellite's components on the same
spacecraft bus, connected via wires. In its place, DARPA is advancing the
concept of fractionated space architectures in which a satellite's nodes
(e.g., sensors, power source, communications downlinks, processors) can be
physically separated into modules that are connected in function via
wireless links so that they create the same capability as their monolithic
counterpart, if not more."

Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Well, Im back. I got frustrated sometime back with the lack of progress
and bleak looking future for HEO's as well as sniping on this list about
HEO's vs. LEO's so I left the list and left AMSAT. Leaving AMSAT was
more of an economics issue, I couldn't afford dues.
Anyway, times are hard around here and I've had to sell my HF radio so
it appears if I'm going to have any radio fun at all, it's going to be
with FM LEO's , ARISS and maybe listening for and tracking cubesats.
Here's what I've got and what my proposed budget is...
I have an older Alinco DJF1T 2 meter HT capable of 5 watts out.
I still have my Orbit OR360 TV rotators with homebrew Saebrtrack basic
stamp based tracking box plus SatPC32 software
I also have some homebrew "cheap yagis", 4 elements on 2 meters and 11
elements on 70cm
Some LMR 400 and some RG8U
Also have Pacific Monolithics 2.4GHZ downconverter that I'm unsure
whether it works.
Also have a 12V power supply.
I've got a fixed budget capped right around $200.00
I'm thinking I can pick up a new or used 70cm HT and get back on the FM
LEO's and I'm talking a "base" setup not portable even though I'd be
using HT's.
Sound doable or am I missing something? I don't have a preamp for 70cm
but maybe if I keep the cable run short I can get by.
And please guys, I haven't been here in awhile and I don't know how the
bb is getting on but don't turn this into some kind of merits of FM
LEO's debate. I can't afford to do anything else right now and this is
the only way I can see to remain in the hobby right now and have a
little fun if indeed my plan is even feasible in the first place.
I'm open to suggestions and advice though. And BTW, what did ever
happen to P3E? Is it rotting away somewhere in storage now?
Tnx and 73,
Michael W4HIJ

In addition to the FM sats, don't forget the APRS downlink on 145.825 from
the Space Station (ISS) and sometimes PCSAT.
You may not have a TNC, but these days, you can just download APRS software
that uses the soundcard.
To see how it all works, look at the LIVE up-to-the-minute downlink captured
by APRS ground stations around the world, all feeding the www.ariss.net
site. Any packets you send up on 145.825 that get digipeated will show up
there.
The site also gives you an idea as to whether the ISS transponder is on or
not. Or you can just put your rig on 144.825 and monitor all day to see
when the passes are (and if it is working). THe downlink is so strong, you
can hear it on an HT with a rubber duck, or your basestation or your mobile
omni.... (IF IT IS ON..) sometimes it is off for days or weeks depending on
astronaut activity.

I saw a CQ packet from PCSAT show up on my Mobile on 144.39 yesterday!
Even I had forgotten that PCSAT does have a downlink on the national APRS
terrestrial 144.39 over NOrth America, and if the channel happens to be
quiet at the instant it transmits, then you can possibly receive it on your
mobile right there along with all the other local traffic!
Sure enough, I quickly QSY'd to its main downlink on 145.825, and there it
was...
THen I went back to my LIST to read the packet in detail and it was GONE!
Yep, the station was beyond my POSITION LIMIT, and so my radio did not save
it.. Drats...
I used to keep posiiton limit turned OFF, so that I could capture these
random packets from hundreds or a thousand miles away, but have not done
that in years.
A quick check of http://pcsat.aprs.org and www.ariss.net (now 24 hours
later) and I can't figure out who it was. The few stations via PCSAT do not
match the W1... callsign I thought I saw. I think it was a message. But
the message or position report did have the words "PCSAT" in them, and that
is what caught my eye on the radio display...
Oh well. SO if you are on the open road far away from heavy activity on
144.39, do not be surprised if you occasionally hear a packet via PCSAT. If
you do, then QSY to 145.825 and try to work them.
PCSAT is basically dead, but when it DOES come over during mid-day in the
Northern Hemisphere it can sometimes have enough power to relay a packet or
two. Being in DEFAULT mode, the 144.39 and 145.825 transmitters are
cross-connected and that is why you can sometimes hear it on 144.39 in an
uncongested area in North America.
But if you have your mobile POSITION LIMIT set to anything shorter than 1000
miles or more, you may not capture them.
This national downlink to ALL mobiles in the country was a capability we had
hoped could be used for ALL-CALL and for emergency message delivery to ANY
ham anywhere even if he was not monitoring the satellite downlink.
Since the New-N paradigm, the amount of congestion and collisions on the
national channel has gone down somewhat and there are some moments of
silence when a weak space packet can get through.

Hi,
Sorry for the offtopic, can somebody help me with getting MixW2 working
with a microHam USB Interface III?
No problems with HRD, DM-780, WSJT but in combination with MixW it is
a pain in the but :)
The main reason for wanting to use MixW is the support for packet.
Maybe a reply offlist
Thanks in advance,

73,
Pete, WB2OQQ
I have a Yaesu FT-736R with a FIF-232C.
CAT will only control the radio if the down link is UHF. It will not
control the radio if the down link is VHF. Any suggestions?
The rotor function with a HR-5400A and a LVB Tracker works great.
