Hello all,
I will be giving satellite demonstrations for passes Saturday and Sunday
from approx 1500-2300z as N0SZ as part of Rocky Mountain Ham Radio at the
Denver Maker Faire from DM79.
I will primarily focus on FM voice and APRS. However, I will have some
borrowed equipment for the linear birds as well. Just go easy on me! Look
for me on Twitter (@xxxxxxxxxxxx for specific pass and frequency
information.
I'm not sure who handles log submission for the group, but I will provide
ADIF to the club so that they can submit.
For more information on Rocky Mountain Ham Radio, visit:

Thanks, and hope to work you this weekend!

Hello,
I am attempting to use SatPC32 12.8c on Windows 7 to control a Yaesu GS-232
rotor to track my university's cubesat. All connections have been doubled
checked for accuracy. In the setup, the 180 degrees max elevation is
selected, along with the correct setup for the com port, and the rotor
interface is set to Yaesu GS232.
For some reason, the software is only registering that the rotor has 90
degrees of elevation still. Meaning that when the rotor controller reads
180 degrees, the software reads 90 degrees. Similarly, when the controller
reads 45 degrees, the software reads 90. It seems that all built in
software settings have been explored and a solution for this problem cannot
be found. Any suggestions?
Thanks

LNA Preamps by all means are required.
But I am curious. It would seem that the turnstyle cannot have any more
gain than a simple dipole (2.3 dBi) circular, but broadside to each
dipole, it should have a net -0.7 dbi since one dipole is contributing
nothing and power is split - 3dB between them.
Yes, it gives 2.3 dbi circular polarization gain overhead which reduces
fading, but has little gain in the quadrant directions. An infinite
reflector can gain another 3 dB but this is not achieved with a simple
reflector element.
On the other hand, a vertical 1/4 wave doesn't do any better. But if the
vertical is made 3/4 waves long, (about 20" tall for UHF) and is placed
over a good sized ground plane, then the gain is over 7 dBi above about 30
degrees.
That's the good news, but the bad news is that Sateliltes only spend about
30% of their total time in view above about 22 degrees as shown on this
page: http://aprs.org/LEO-tracking.html
But the high elevation gain of the simple 3/4 wave vertical above 30
degrees is shown about 80% down this very long page:
http://aprs.org/astars.html
As an old fud, I hold to this firmly held belief about the same as other
old fud's cling to theirs, so I hope someday to actually make some real
comparisions instead of just talking about it.
But here is my bottom line, Turnstyles and egg beaters (in my opinion)
are excellent omni directional cross polarized antennas for satellite
work... but equally poor in all directions. In other words, they
sacrifice gain when the satellite is higher and much close, for gain at
the horizon where they can never possibly hear a weak satellite anway.
So I like the reverse. Sacrificing gain at the horizon, where I can't
hear them anyway, for higher gain higher up when they are closer and give
a 5 dB stronger signal.
So for a simple quick test, put up a 19" quarter wave whip over a ground
plane and it will give you 5 dBi gain on VHF above about 15 degrees and 7
dBi gain on UHF above about 20 degrees.
Your mileage may vary.
Bob, WB4APR

Hi Christopher,
It sounds as though your interface unit (sitting between the COM port and
your rotator controller) is only set for 90 degree elevation, or, possibly,
just needs recalibrating.
I'd be looking there first.

Be very careful about "Doppler correction" for digital modes.
>Falconsat just went over
>435.111 MHz to 435.095 MHz doppler corrected using MacDoppler...
Digital modes usually cannot stand the phase shift that occurs every time a
radio steps in frequency. Those bits are lost. If you set to 100 Hz
steps, over the full 18 kHz of Doppler, then 180 times during the pass, you
are *destroying* the data you are trying to decode.
So it is better to maybe step every 1 KHz and only have 18 blackouts instead
of 180.
Assuming the decoder can still work with up to 500 Hz offset.
Doppler stepping is very helpful for SSB voice modes. But disasterous for
digital. That is for step tuned radios anyway.... I assume smart Doppler
correction in DSP receivers work around this problem?

Hi All,
As we are busy preparing for the AMSAT-UK Colloquium this weekend, FUNcube-1
is now in full time amateur mode. The Transponder is on and the telemetry is
operating at low power. This mode should continue until Monday morning UTC
time.
Nayif-1 EO88 remains in autonomous mode and FUNcube-2 on UKube is in amateur

As an alternative, try http://amsat.org.ar/pass.exe .
This app uses driver at http://amsat.org.ar/wispdde.exe
Which allow setup and control GS-232 rotor as well as Dopplers on or
offline.
Just click on the Satellite to be tracked, rotor and rigs are settled.
Wishing good luck with your University Cubesat.

Hi,
??? Just to be clear here, your G-5500 or G-5400 control box? says 180
elevation but your GS-232 interface connected to satpc32 says 90?? have
you tried using a terminal program like "putty" or hyperterm to talk
directly to the GS-232 and issued the B command to see that elevation
really is being reported as 180 by the GS-232, depending on the results
you would at least know if it is a rotor/interface issue or a satpc32 issue.

All:
I have the opportunity to purchase a used Timewave PK-96 USB TNC for a
very reasonable price. I have 2 9600 baud radios which will do nicely
for up-link and down-link.
I plan on wiring the TNC for both rigs by connecting the TNC's RX pins
to one radio and the TX pins to the other. Before I do so, is there
anything I should know before trying this setup with Wisp? Anyone using
the PK-96 USB?
For what it's worth, I'm told a 9600 baud TNC will pop up on eBay now
and then. It's worth a look for those interested in Falconsat.

Maybe somebody can help me out. I am switching out computers and
installed SatPC32 on the other machine. It's been a while since being on
the satellites and forgot some operating functions with the SW. When
SatPC32 is correcting for doppler does both Uplink/downlink frequencies
change on the radio? Or just uplink? I have "At Satellite doppler"
enabled. I noticed the only one changing was the uplink. Any help?
Thanks,
Todd

I'm using the AirSpy (not mini) with SDR#. Doppler tuning with homebrew
software. Haven't noticed lost packets when the SDR freq changes, but will
be on the lookout for that.
The audio loopback is Virtual Audio Cable.
SSB Preamp
Rotator is a G5500 and LVB Tracker controlled by my homebrew software. (I
really like the LVB Tracker!)
Sound modem is Dire Wolf which feeds APRS-IS. At the present time I'm just
watching the packets scroll by on the Dire Wolf display. My main goal was to
Igate the FalconSat-3 packets.
