Here's something to think about. L band is a lot of fun. We do get 24
hours once a week (not complaining). With several ISS passes every day. It
is a good reflector. Plus we can use CW, SSB, many digi modes. Just google
it.

Hi all,
I have been following on the "Amsat-bbs" the various messages and
information regarding the predictions on the Re- entry of "Tiangong -1"
Of course the re-entry transpired in the ball part as predicted at approx.
00.15 hrs GMT.
Many will be aware of the work carried out by " CHORDS " but perhaps many
have never even heard of the organisation and its work.
They are greatly involved with the work and tracking of "Space Debri" and
the concerns.
Tiangong -1 with co-ordination from a number of parties was fitted with an
"REBR Probe" - It logged an sent various data from the spacecraft
to enhance its locations for predictions.
I understand that further work and developments of the probe have also been
made recently so many may find this topic of interest.

Hello Joe,
Thanks for the reply, appreciate it.
Yes, the phasing harness is different, but my guess was that this
shouldn't make a lot of difference as long as you get the 90 degree
phase and the impedance right. If you look at the radiation patterns for
both then they are nearly identical, hence my question if they are not
one and the same thing.
It came up here because I have two DCAs right now, one for 2m, one for
70cm, both RHCP, no pre-amps. I do hear some birds, but signals are very
weak. The 2m one works fine when receiving the NOAA wx sats, so I was
wondering if the 30 degree angle of the Lindenblad would be better for
amateur sats. I lack the knowledge to understand the difference between,
what you say, the geosynchronous orbit of NOAA sats and the LEO orbits
of our sats. NOAA wx sats are also LEO sats, not? I'll see if Google
turns up something there.
It's easy for me to change the tilt of my DCAs to 30 degrees, so I'll
try that this week. Should be a nice experiment.

Neither are going to hear much on the horizon for typical weak amateur
satellites where they spend most of their time. These antennas have gain
that is at best 3 dBi
It is very important to understand that all Low Earth Orbit sateliltes
spend more than 70% of their in-view time below about 22 degrees. And
satellites that low are 6 to 10dB farther away than when they are high up
above 45 degreees. See the scale drawing of an orbit on the right side of
this page:
http://aprs.org/LEO-tracking.html
The DCA and Lindenblad and Eggbeaters and all other such omni antennas are
designed to give good performance over all elevation angles for
sateliltes. But to do this, they are equally poor in all directions.
This is wasteful since you need less gain at high elevations and much more
gain at lower elevations for LEOS (98% of all amateur sateliltes?).
So you have two choices. Use an omni and only get high passes (less than
30% of all time-in-view), and hear only strong satelites down on the
horizon...
Or, use a terrestrial style antenna with gain on the horizon... but by
definition, these will have a null higher up, and for a typical mobile
whip, that null might be at 15 or 20 degrees which is right where
satellites spend their most time.
Best option is to switch back and forth... but then if you are going to be
sitting there, y ou may as well control a beam...
(I still have not found such an ideal antenna (though lots of claims are
made)...
On the other hand, if I am going to simply want OMNI coverage for
satellites above about 30 degree, then I prefer the simple 19.25"
quarterwave whip over a big ground plane. Because this gives 5 dBi on 2
meters and about 7 dBi on UHF and is nothing more than a 19.25" piece of
wire sticking up from a large ground plane. Much easier than all those
other omnis that provide less gain everywhere.
Though I have never done rigorous studies to prove its performance. But
what could be simpler to test. If I had any of those complex omni's., I'd
love to do such a comparison some day... after I retire...

Hi to all.
This is half OT, sorry for that.
As you may know Cuba has (now) a growing network infrastructure for the
National Ham Radio Association with at least a node with ADSL in each
province and a internet connected central link in Havana; I have managed
to make strong links with the Senior System Administrator (I'm a
sysadmin also) and we are willing to put more ham related services in
the net mostly for local users that connect to it via dialup connections
(almost 30% of the hams are registered) and why not for international users.
We tested and setup a DXcluster (Linked DXSpider node) that was a big
success among our users.
We are now thinking on kind of internet connected APRS server that acts
as a gate (kind of proxy) for the internal network and then a first node
on my city (Camag?ey, 500 Km east of Havana, FL11BJ) to test a on-air
APRS and link it to the internal APRS server and I was thinking on
setting a VHF packet on 145.825 Mhz as a bi-directional Sat-gate.
The main questions are this: (Any advice, critics, links, help is
appreciated)
* There are any real interest in a VHF APRS SAT GATE in my location
(FL11BJ) ? or it will be more noise in the net...
* Any lead in how to mount a internet only aprs server and how to link
it to the global APRS internet network?
* Any other suggestion on what network-ham-related project we can
setup on the national network described on the first paragraph?
* Any other list/reflector where this can be interesting... ?
The OS by choice will be Linux (Debian 9 or Ubuntu LTS), we plan to use
direwolf as software modem on linux, we are seeking for a rbpi to test
as we have no real hardware right now but a trusty Yaesu FTL-2011 VHF
radio, we are on the plan stage and seeking for advice.
I'm all ears,

Great plots... Now add a 1/4 wave monopole plot. It has a null straight
up, but the time any satellite is in that null is less than 5% of the
time, and at those higher elevations, the satellite is 10 dB stronger
anyway. So the impact is minimal... And it has a smooth response
without all those nulls of the others... And include a 3/4 wave
vertical plot and pick up another 2 dBi... above 30 deg.

Note: I'm also trying to use it on a Mac. I have no interest in putting
the JDK on my Mac, but at this point I have not been able to pass in
arguments. Mac uses a thing called the "Jar Launcher" which knows how to
find the JVM, but apparently does not pass arguments to it. I think I can
manage to get this to work with an appropriate script yet, but have not
totally done that. I'd like to know how Jar Launcher knows where to find
the jvm. I think I know where it is, but it looks like it is in a browser
plugin; no idea if it would be in a consistent location for Safari, Chrome,
etc users.
If anyone knows this stuff, please let me know.
Oh, and let me just say that you can search all you want on Google for
this; everyone that answers seems to have JDK installed. In that case, you
can just type 'java' to get the JVM and all is well. I want to know
WITHOUT the JDK.

Keep in mind that ANY omni antenna is going to be pretty dismal on receiving
satellites. So although there are some differences, we talking about total
crap or only partially crap. Based on my own experiences with a couple of
different omni antennas, as I recall a few years back when I was trying to
pass decoded packets from the original PC-Sat (if I remember right), the
best I could do was a couple of decoded packets per week. Between the weak
signal and no automated dopler shift, it was pretty much wasted effort. One
thing going against me is that I live in the very RF congested Los Angeles
basin, so that may have been working against me.
