Did a full reset on the radio but must have lost a setting.
I am able to CAT connect w/HRD. Set the baud rate to match
radio/HRD/Satpc32.
In HRD, I can trigger SAT but the radio is not reading the frequencies
(check boxes are checked). In SATPC32, I am not able to trigger the SAT
function. (baud rate matches radio)
All was well in the past. I think I am missing something on the radio side.
Cable connections all tight
Any help appreciated

The Goddard Space Flight Center club station WA3NAN just completed a voice
contact with NA1SS on the space station on the 21:36 UTC pass. Bob McCown
N3IYI was the control operator. Reid Wiseman said "Goddard, that's just down
the road from where I grew up.".

Hello,
I’m hoping to be writing an article about FD and the activity on the Amateur Satellites. It would be helpful, to the story, if the stations operating provided me with the call sign you will be using along with your operating class and ARRL section. I will be on all the available satellites using the call W2GSB, 5A, NLI and W2TOB for the GOTA contacts.
Good Luck, Have Fun and talk up AMSAT, thank you.

All:
Trying to make this work on a new install of Windows7, 64 bit. According to the
help file, this should work, but every time I start SATPC32, it wants IOPORT.SYS
in WINNT/SYSTEM32/DRIVERS. Which I created, but still doesn't start without
complaining.
Any suggestions?
Thanks & 73,
Jim

Been awhile since I used the program with my FT 847. Should changing the C
to C+ be putting the radio in CAT mode? It is not
Also looking for the red TX and RX buttons
Thanks, Ted

Subject: W5KUB Live Webcast of Field Day
Please join W5KUB.com during our live Field Day webcast this Saturday and Sunday, June 28 th & 29 th , rain or shine. To join the webcast go to http://W5KUB.com where the fun begins!
This year we will provide live video of four Field Day operations in the Mid-South. See what it takes to set up emergency communications and watch amateur radio operators compete for highest score. We will also have a segment showing satellite contacts. You will see the fierce competition side of some amateurs, while you will see others just enjoying the outing and having fun. You can communicate real time with hams at these events and other hams around the world via our chat room
Below is our tentative schedule:
Saturday June 28 th
12:00 PM CT (1800 UTC) – Memphis, Tennessee Field Day This is a joint event with the Delta Amateur Radio Club, the Mid-South Amateur Radio Association, and the Tri-State Repeater Club. There will be HF, VHF, UHF operations, including satellite contacts. According to ARRL, the International Space Station may participate in Field Day.
Unknown time - K4BFT, Huntsville Amateur Radio Club from the US Space and Rocket Center in Huntsville, Alabama.
Sunday, June 29 th
8:00 AM CT (1400 UTC) - Olive Branch Amateur Radio Club from Olive Branch, Mississippi.
1:00 PM CT (1900 UTC) - Northeast Mississippi Radio Amateurs club in Fulton, Mississippi. In addition, we will interview our friend Ray Novak from Icom as he is operating from the Fulton location.
Unknown time - K4BFT, Huntsville Amateur Radio Club from the US Space and Rocket Center in Huntsville, Alabama.
During our drive time between events, we will tentatively webcast the Huntsville Field Day.
Please help spread the word by posting this announcement in Facebook and forwarding this message to your ham radio friends that may not have received this message! Join our group on Facebook at https://www.facebook.com/groups/w5kub/ to keep up with us year-round.
We'll 'see' you at Field Day!

All:
Two problems with Nova after the move from Windows 7:
1. It doesn't run. Throws Exception ERegistryException in module
Nfw32.exe at 00079BEE. Failed to set data for ".
Can Nova run on Win7 (32bit??)
2. Can't find my registration number or activation code or whatever?
Any way to recover this?
Thanks, and good luck at FD!

To Flip or Not to Flip
Ok, my setup has flip capability. It also has azimuth of 1.5 turns
(540 degrees),
So flip is not essential for end stops as the rotator neither stops at
North nor South
The rotator controller software only works in WiSPDDE but this can use
many different tracking software types.
Currently using Orbitron. Orbitron only outputs Elevation 0-90 and Az 0-360
The WiSPDDE rotator driver has been modified to automatically flip if
elevation goes above 70 degrees and starts to drop again. As soon as
it starts to drop Elevation, Azimuth value has 180 degrees added and
Elevation is now suddenly >90
The software has the option to enable or disable flip on each pass.
What I need to know is
1) What is the best way to predict if I should flip or instead just
move the azimuth without flipping?
2) Is there any software to automatically decide if Flip is best, and
output Elevation values >180 to WiSPDDE during the middle of a pass?
For Example worst case would be a satellite coming from due west (270)
heading east (90).
I this case it would be best to flip antenna, otherwise azimuth would
need to rotate 180 degrees suddenly during a pass.
In another case, ISS coming from south west across to south and then
south east, but with elevation approaching 85 degrees. In this case it
would be best to not flip, but our current software flips once the box
is ticked and if the elevation rises above 70 degrees.
At the moment it is not possible to do this in WiSPDDE as it does not
know where the ISS is going to be at the end of the pass as that info
is not sent over the DDE interface.
Specific System Setup
The system will be used to track the ISS for 2.4Ghz HAMTV downlink.
The beamwidth of dish is 4 to 8 degrees, but signal is very strong at
high elevations.
Video is used live so continous accurate tracking is needed
The azimuth can be any value 0-540 degrees (1.5 turns). Currently the
software can do 2 things.
1) Not flip but instead move to an azimuth position where flip is not
essential, but sometimes the azimuth is too slow to get to the new
position.
2) Flip the dish, but on some passes it would be better to not flip
the dish, if say elevation went to 73 elevation but azimuth could cope
with tracking.
The decision is currently a tick box. Orbitron only outputs 0-90
Elevation so WiSPDDE is not being told by Orbitron to flip, the
decision is not based on the pass prediction.
I believe some of these problems may be solved with SatPC32 but we
would possibly need to modify our custom driver to just accept these
values.
If using SatPC32 would it solve all these issues? Can it decide to
flip or not flip based on azimuth speed and pass prediction in the
middle of a pass?
Does SatPC32 only ever flip at the start of a pass and never in the
middle of a pass?
Will it pick the best option for every pass and output values via DDE
to WiSPDDE?
The rotator WiSPDDE is specifically written for this task,
It is a modified version specially modified by Amasat Itallia.
The rotator we are using is prosistel Azimuth and Elevation rotator.
This is quite new and so a specific driver was written.
The azimuth can achieve 1.5 turns (540 degrees) and Elevation 180. The
manufacturer only specifies Az 360 and Elev 90 but we have special
modified hardware and software to allow movement above normal range.
We have been using Orbitron up to now as it allows sun tracking which
is handy for dish calibration,
In reality the setup may not be used too often for school contacts and
we could perform a manual pre-test or simulation to see if flip is
best.
Another option is to just not use passes for school contacts that
require flip or that will result in a signal loss in the middle of a
pass.
What I would like to happen is the software to calculate which option
is best, to flip on the fly or not to flip
The decision would be based on the speed of the motors and which mode
is fastest to keep a signal locked.
For example
Time in seconds 1 AZ 260 El 45
Time in seconds 2 Az 90 El 80
Assuming both Elevation and Azimuth can move a 5 degrees per second
Difference without Flip
Az 170 El 35 Max Time to correct position 34 seconds
Difference with Flip
AZ 10 El 50 Max time to correct position 10 seconds
So is there any program that does this and can output to WiSPDDE?
