Good stuff, Joanne...thanks
One thing, though, that I have never understood, however: Does SatPC32 properly update keps and the sqf data when the 'update' option is used in the program? Or do we need to keep updating manually. I can understand with a new sat, manually trying to find the right data, but after the sats are rolling along for a few weeks the normal sites that identify keps usually have that data current.
Thanks for any input

I’m not sure if you received a private response but I have a similar issue. I tried to use SatPC32 the other day and found many of the satellite frequencies were not correct. I’m going to have manually edit a bunch of them unless I can find someone with a good set of files.

Hi Ted,
As nice as it would seem, it really isn't possible to automatically update the DOPPLER.SQF file. The most important reason is that each station has a different transmit and receive offset due to different RX and TX chain frequency calibration, drift, etc. It would be possible to have a baseline SQF file (without compensation) and a few hams do publish that.
You can manually update the Kep files yourself.

Well there is updating the Keps (not sure if you mean that). There is also updating your personal uplink/downlink correction factors. The latter is why SQF files are personal. I use two different rigs (and IC-9100 at home and a IC-910H on the road), the SQF files are different.

There is a window that allows you to download and update the Keps. Any changes to the sqf files for new satellites or modes are performed by you manually.

Keps are the Keplarian elements that define a satellite’s orbit and are used to predict its location. You have to update these every few days (daily for ISS, which reboots its orbit from time to time). You trigger the update manually, using the Update Keps button, and specify the update source for the keps — the nasabare keps from AMSAT are a good choice (they include AO-85).
The sqf file contains information that defines the operational modes of a satellite (frequencies, tones, modulation, and so on). This info gets entered once when the satellite is new. It might need to change if the frequency drifts with age or if a new satellite isn’t operating as expected, but generally remains fixed. You edit this file with a text editor.

Keps are the Keplarian elements that define a satellite’s orbit and are used to predict its location. You have to update these every few days (daily for ISS, which reboots its orbit from time to time). You trigger the update manually, using the Update Keps button, and specify the update source for the keps — the nasabare keps from AMSAT are a good choice (they include AO-85).
The sqf file contains information that defines the operational modes of a satellite (frequencies, tones, modulation, and so on). This info gets entered once when the satellite is new. It might need to change if the frequency drifts with age or if a new satellite isn’t operating as expected, but generally remains fixed. You edit this file with a text editor.

Ted,
There is a window that allows you to download and update the Keps. Any changes to the sqf files for new satellites or modes are performed by you manually.

Hi Ted,
As nice as it would seem, it really isn't possible to automatically update the DOPPLER.SQF file. The most important reason is that each station has a different transmit and receive offset due to different RX and TX chain frequency calibration, drift, etc. It would be possible to have a baseline SQF file (without compensation) and a few hams do publish that.
You can manually update the Kep files yourself.

One thing, though, that I have never understood, however: Does SatPC32 properly update keps and the sqf data when the 'update' option is used in the program? Or do we need to keep updating manually. I can understand with a new sat, manually trying to find the right data, but after the sats are rolling along for a few weeks the normal sites that identify keps usually have that data current.

I tried to use SatPC32 the other day and found many of the satellite frequencies were not correct. I’m going to have manually edit a bunch of them unless I can find someone with a good set of files.

Ted,
Have the above answered your questions? Seems to me two different issues have been mixed here as the Keps and Doppler.sqf are two different items and updating one does not up date the other
1. The Keps can be updated from a number of sources to be found on the drop down under the <Satellites> tab 2. Doppler.SQF is manually updated by you when a new satellite is added to the family using Notepad or some kind of text editor. Be sure to follow the rules embedded in Doppler.SQF when messing with the file. You can save a copy that has not been modified the the Uplink calibration process as Doppler.REF or some such thing. And, yes, each radio has slightly different calibration offsets in Doppler.SQF. That is what I use the 4 different configuration options for <Setup><Configurations>. I use one config for a pair of FT-817's another for an IC-910H and a third for Flex 6600. 3. Don't forget if you are adding a new FM satellite to Doppler.SQF you also need to go into Subtones.SQF and add the new satellite to that list as well so the T0 > T1 >T2 toggle works correctly. Again follow the embedded instructions carefully. This is another file that can be manipulated with a text editor like Notepad.
Hope this helps,
John

Doppler.SQF are defined and managed by the user, updating TLEs has no effect on it.
It's worth remembering frequencies will be always need tweaked during configuration, rigs can be off frequency or even drift.
