I've been wondering if anyone besides me has tried to hear themselves
using an Arrow or Elk antenna via ARISSat's linear transponder.
If you have tried it and successfully heard yourself, please let me
know. I'm curious as to what was your formula for success. The rig
I've been using is an FT-847 and for an antenna either my Elk or Arrow
mounted to a camera tripod.
I've made about six attempts now on passes that I thought were very
favorable to success. I've had zero trouble receiving telemetry or
SSTV during these passes so I'm sure the bird was actually overhead
during my attempts.
I'm not ready to give up but time is running out.
There's Gpredict http://gpredict.oz9aec.net/download.php
As with all code - the best code is written by the user, especially with something like satellite tracking where the theory and UI challenge is quite demanding. There are many who can talk long and loud, but how many have actually written working tracking software?
(I'm not getting at Dominic here.)

Neither of those mentioned so far are Open Source, but I'd love to know
too - Mike, which ones are you using?
I know this sounds lame but anyone know where I can enter lat and lon and get my location. All my gps does really is give lat&lon which is fine, but all the things I have found you click on the map and it gives everything with grid but I want to do the reverse, so when I am driving around I can punch in my gps cooridnates and get my location /grid on the map.
Thanks for any help. :)
Does anyone on this list have a working E-Mail address for HB9DRV the developer of Ham Radio Deluxe? I would like to get in touch with him as I have a few questions regarding the satellite tracking portion of the software. Thanks in advance.

I was given a Radio Shack antenna rotator, model number 15-1245A, that I figured was good enough to turn my small Cushcraft Dual Band 3 element yagi
I sometimes use for some satellite work. But the rotator is need of some clearing and lubrication. Has anyone taken one of these apart and can share some insight as to what I might expect to find once I remove the motor and gear assembly from it's housing. I assume the 4 large bolts inside the bottom cover where you would attach the wires are holding the motor assembly in place. Are there any ball bearings that I might expect to come rolling out if I disassemble it? I looked for a You Tube video for some help but came up empty. Figured the next best place to ask would be with other satellite operators.
Excerpt from Press Release of September 19, 2011
Tampa FL, St. Paul MN, Pittsburgh PA - September 19, 2011 -
Mike Carper (WA9PIE), Randy Gawtry (K0CBH) and Rick Ruhl (W4PC) have
acquired the source and rights to the Ham Radio Deluxe (HRD) suite of
All three principals have more than 25 years of experience with radio data
Rick Ruhl (W4PC) is the president of W4PC Software, Inc. whose products
include the PakRatt, PKTerm and Radio Operations Center software suites.
Randy Gawtry (K0CBH) is the president of Timewave Technology Inc. whose
products include the PK and DSP families of data controllers and other
commercial data products.
Mike Carper (WA9PIE) is an experienced Fortune 500 technology executive,
educator, and featured speaker in the areas of wireless technologies and IT
"After many years writing the HRD software it's necessary to take a break
and hand the whole project over to another team," said Simon Brown (HB9DRV).
"The support effort required has become more than I can realistically manage
- with many thousands of users, new radios and other hardware appearing all
the time and unexpected changes to the infrastructure used by HRD such as
QRZ.com I no longer have any time at all for other projects.
As some of you will know I have formed a company SDR-RADIO.com GmbH and am
now working in the Software Defined Radio arena with RFspace.
This is the technology of the future; a future which I want a part of.
In 2012 I plan to return to England and get back on the air, something I
haven't done much during the last 25 years."
The new owners of HRD are in the process of building a development
environment for HRD and plans to begin by addressing some of the bugs
in the existing "To Do List" for an upcoming 5.1 release. The 5.1 release
will be made available at no charge to registered users when completed.

Fellow satellite enthusiasts;
We fervently request your assistance in receiving transmissions from an
upcoming satellite, AubieSat-1, immediately after its launch from
Vandenberg AFB, California, USA, 25 October 2011 at 9:52 UTC.
AubieSat-1 (AS-1) is an undergraduate - built CubeSat satellite
developed by Auburn University.
AS-1 is designed to transmit with a power of about 800 milliwatts on a
frequency of 437.475 MHz, plus or minus Doppler correction. The beacon
signal, along with telemetry, will be sent using A1A continuous wave
Morse code at 20 words per minute. Additional telemetry from the
onboard science experiment will use CW transmissions up to 60 WPM.
Based on the pre-launch orbital data provided by NASA, AS-1 will
activate after deployment at 12:21 UTC, 25 October 2011. At that time,
the sub-satellite point will be at 34.52 S latitude and 1.52 W
longitude over the South Atlantic Ocean.
Our predictions are that the first flights over the contiguous United
States will begin as shown in the following table:
Orbit AOS Apogee LOS General Locale
3 15:54 UTC >50 deg 16:01 UTC New York
4 17:28 UTC >26 deg 17:35 UTC Texas
5 19:07 UTC >48 deg 19:14 UTC California
This information will be updated should there be launch scrubs or
performance changes in the launch, and additional information will
be available upon request for specific locations. Reception reports with
data contents are welcomed to the following email addresses:
wersijp at auburn dot edu and tam0013 at auburn dot edu
An internet Echolink conference group is also planned to begin
one-half hour prior to launch and continue until about 30 minutes after
confirmation of the first receipt of signals from the satellite.
Information on the conference groups title will be distributed nearer to
the launch for interested stations.
Please email wersijp at auburn dot edu if you require
additional information and can assist in the reception and tracking
of AS-1. Thank you.

"Common sense is the collection of prejudices acquired by age eighteen."
Previously we have been using the ICOM IC-910H transceiver with
SATPC32ISS for doppler control for our ARISS school contacts. Due to
ISS has both its TX and RX frequencies in the 2M band, we had to use
an extra wire between the IC-910H's ACC jack and the PC's COM port to
inhibit frequency changes while the radio is transmitting.
Based on the "What's New" document of SATPC32ISS
(http://www.dk1tb.de/What's%20New.txt), it is noted that the extra
wire between IC-910H's ACC jack and the PC's COM port is no longer
needed from version 12.8a onwards. However, when we did a simulation
of this, we notice that should the frequency changes (due to doppler
shift) while the radio is in transmit mode, the TX and RX frequency
swaps (TX frequency becomes RX while RX frequency becomes TX) - as
what used to happen during previous version when the ACC wire is not
I wonder if there are some configurations that we need to check? Or
is there something that we are doing wrong here? The IC-910H is
connected via a G4ZLP ICOM CI-V cable to the PC's build in COM port.
Any pointers or suggestions will be greatly appreciated. Thank you.
