Hi, Tim;
We still make the S/L patch feeds and may bring back the tribander, if
there's enough demand. We also still produce the 1.2m and 1.8m dish kits
and now have a 2.4m kit in the works. It's been the UAV industry that's
kept us alive since the failure of AO-40, so our products are now made from
aircraft grade aluminum and are milspec Class II gold anodized.

I am not sure Tek Sharp continues to make the patch feeds. They certainly
do not make the tri-band feed, but I was able to get a dual band patch from
them in June 2009 for one of their hardware cloth dishes.

Plans are to activate EL97 on both AO-27 passes on Saturday,
7 January 2012 at 1824z and 2005z. Equipment checked out ok
on today's AO-27 eastern Atlantic pass.
Please do not send qsl card requests. Simply send an email
with the qso data and I will send a card direct. I do not
plan to make a LOTW filing for all contacts, but if you need
one, just make a note of it in your email.
Weather here in Central Florida should be sunny and in the 70's.

Wayne,
I share your surprise that frequency information is not available in a
machine readable format. As the cube sats are coming fast and furious, it
makes keeping up with them harder.

Help me understand something.
Doppler.sqf is a file specific for SatPC32. When you download the
program, Erich has provided a basic doppler.sqf file for you to use.
Most folks have customized them with +- frequency adjustments for
their own location, setup, radio etc. As much as I like plug and play,
don't you want your own setup for your station and consequently learn
how to do it? Looking up a new frequency for a satellite is as easy as
reading emails and editing the files is even easier. Maybe I am
missing something.....
Now, It only takes one volunteer to compile information and submit it
to AMSAT. How wants to do it?
Happy New Year!

Ok so I think that this all fine and dandy and even more so if it keeps
people from logging into the BBS and ruining the pass for everyone else. I
dont think that an email sent via ISS would be considered a Qso but still
pretty neat. In between the beacons there are Two Way Communications made on
the ISS Digi.
What I do not understand is the Beaconing. What is the point? So that while
you are at work, or sleeping, your callsign shows up on arris.net? In doing
so you Beaconers not only clog up the passes but have basicly killed NO-44.
If you are going to use the ISS or a satellite you should be there at your
station and not be like the very annoying automated menu you get when trying
to get through to a human being on the phone.
By the way Unproto CQ via WIDE2-2 or RS0ISS-4 then k or CONVERSE :EMAIL
:SUMMIT496@xxxx.xxx Type mess here works great there is no need for the
Beacon...
Just my opinion.

I agree, Kevin. The unattended beacons seem pointless. Unlike propagation
beacons, these don't really tell us anything. My guess is these people are
beaconing every minute or so 24x7, ISS passing or not.
Satgates don't need to identify to be beneficial. My dad and I have both
successfully tested experimental Satgates using just a simple receiver with
a ground plane, feeding into a computer sound card. This is essentially all
you need to relay ARISS-digipeated frames to the APRS-IS network.

Have you thought about upgrading your station to full-duplex capability?
I realize that many amateurs jump into the satellite fray by utilizing
an existing handheld radio and an antenna like the Arrow, Elk, or
tape-measure beam. It's a great way to get your feet wet and make
that "first" contact via the birds.
Now, let's look at how we can do BETTER.
Full-duplex has a very important purpose in the satellite world. It
allows you, the ground station, to know that your signal is being
received and retransmitted by the satellite. I?m not saying it is a
mandatory but once you see its benefit, you may never want to go
?semi? again.
How do you really know you are being heard by the bird if you can't
hear yourself? Answer: You don't.
How do you know another station wasn't already being captured by the
bird and in the middle of a QSO when you transmit? Answer: You don't.
Let's talk about HOW to do full-duplex. First of all, you don't need
base-station radios like the Icom IC-9100, IC-910, Kenwood TS-2000, or
Yaesu FT-847. If you own two handhelds, chances are you have what you
need!
What you need is at least one radio capable of transmitting on the
uplink and one radio capable of receiving on the downlink. For
example using AO-27:
1. A 2m-only HT, set to the satellite's uplink, ~145.85 MHz.
2. A 70cm-only HT, set to the satellite's downlink, ~436.795 MHz.
One added benefit is that while hearing the downlink, you can twist
your handheld
antennas (like the Arrow) to match polarity and peak your uplink.
Technically you do not even need a radio capable of transmitting to
hear yourself on the downlink. A scanner or pocket receiver works
dandy!
To get into full-duplex inexpensively, there are numerous options.
You can buy a NEW Baeofeng UV-3R for about $50-60 USD, shipped. This
radio could serve as an uplink or downlink radio, depending on your
need. I?m not peddling these radios but using them as an example.
If you have the Arrow with the built-in diplexer, simply bypass it by
running a patch cord from each radio to the respective UHF and VHF
beams. If you are running an Elk or tape-measure 2m beam, you will
need an inexpensive diplexer to give you both 2m and 70cm feed points.
One can be constructed easily or purchased from numerous vendors for
$30-80.
Give full-duplex a try. You will not only help the satellite
community by eliminating unnecessary hetero-dyning tug-of-war, it will
generally make you sound better on the birds! Oh, and use a pair of
earphones or a headset when you give it a try to avoid feedback.

There was a FT530 going for $50 today on QRZ.COM. That is one of the best
full duplex HTs made. . You can usually find a W32A for $150 or so also. I
have also seen lots of Alinco DJ-580s recently for good prices as well.

The only addition to your list is a receive preamp if you're running full
duplex. Kit I use is $45 from DEMI BUT it's all smd plus tuning. Best thing
I've ever done for my receive side, though.

I started out using full duplex, and it's a much nicer
experience. I'd recommend it for every satellite operator.

I recall the "fun" part of full duplex on AO-40 (sobsob) was there was a
significant delay with the returned signal and? you started talking a little
weird if you didn't turn down the volume a bit.? Mayabe again someday.? My
satpc prog ram ?it totally messed up.

Hi Bob,
I'm sorry that you have problems with the program.
I suppose you are running the latest version 12.8b. Also, I suppose the
program worked when you first started it after installation and the problems
occured after you configured it.
The best will be:
Uninstall the program and re-install it. It should now start with the
settings that come with the setup file. Then configure the program
step-by-step.
COM port error:
The COM port for CAT control can be chosen in menu "Radio Setup". Make sure
that the port is available on your system and not in use by another program.
With the Windows System panel check which COM ports are available on your
system. If you use a USB-to-Serial adapter the COM port number will change
if you change the USB port! That would explain that COM 3 is no longer
available.
No source file found error.
I have described that error in the FAQs file (sect. 5 h). I have just
updated that section in the FAQs file on my website. You can open that file
with the link on my website www.dk1tb.de, English page "Downloads". Please,
read the item 5h carefully.
When you have a flawlessly working configuration start the program
"DataBackup" from the SatPC32 menu "Programs" and save your settings. So,
you can easily restore the working configurations if problems occur lateron.
73s, Erich, DK1TB
