Usually the standard TLEs from the internet contain far more satellites than you're interested in. More satellites equals more time to search and more time to predict future passes.
In the VIEW ALL page, each satellite has a checkbox next to it. Check of each satellite you are interested in and click SAVE at the bottom. Now only those satellites that you've selected will be considered when you search and predict future passes. This greatly improves performance.
Note that having no satellites is the same and including them all.
Custom TLE Files
Instead of using a URL as a source of TLEs you can instead upload a file. The file must be a standard ASCII TLE text file and must not contain any headers such as comments or other fluff, eg. it must start with a satellite name. The uploaded file will replace any stored TLEs. The favorites option will work with a custom TLE.
Auto Update TLE
If enabled, the S.A.T. will automatically download a copy of the TLEs from the same url that they were last downloaded from. TLEs will only be downloaded while the S.A.T. is idle. It's also going to check exactly the number of days you enter. If you last downloaded TLEs on Oct 1st at 9am, then it will try on Oct 3rd at 9am. If the S.A.T. is not idle at that exact time it will try when it becomes idle.
You cannot use the custom TLE function with automatic updates. Be sure to disable the automatic updates by entering a zero in the AUTO UPDATE field.
QSO LOG w/ ADIF EXPORT
Your S.A.T. contains a call log feature with internet lookups and macros.
Press the CALL LOG button at the bottom of the page to open the call log entry window. If you have set your QRZ login credentials in the LOCATION page then you can use the LOOKUP button to automatically fill in the log entry fields. (You must be a paid QRZ subscriber for this to work.)
Fields such as Date, Time, Satellite Name, Frequency, Mode, etc. are automatically filled using the currently selected satellite and transponder.
The Comment field supports 'replacement' macros and can be saved between sessions. For example if you often have a comment such as "Thanks KC2SYF for the RS-44 contact." you do not need to type it in every time. Simply enter a comment as "Thanks $c for the $s contact." The '$c' will be replace with the call sign of the contact and the '$s' will be replace with the current satellite name. The legend for the available replacement types can be found below the comment field.
The call log entries are displayed in the lower part of the page, above the bottom row of buttons.
You can download your log entries in ADI format with the DOWNLOAD button. The file will be saved with a unique file name wherever your brower places Downloaded files. The QSO log is saved on the S.A.T. between power cycles but it only holds 100 entries and should be downloaded frequently since they only exist on the device and are not backed up.
If the transponder has "FT4" in the name then the ADIF file will export with Mode=MFSK and Submode=FT4.
ADD ENTRY - Store the current entry into log.
CLEAR ENTRY - Clear the entry fields.
DOWNLOAD LOG - Download the stored log in ADI format.
DELETE LOG - Delete the stored log.
The S.A.T. can also send log entries to many desktop logging programs. DX Keeper, Ham Radio Deluxe, Log4OM and N1MM. If your logger accepts ADIF records over TCP or UDP it may also work. Remember to set the IP address and port of your logging software in the LOCATION settings page in your S.A.T.
Log Software Setup Instructions
DX Keeper - Press the Config button and select the Defaults tab. In the Network Service area you can set the port. The default port is 52000 and this causes DX Keeper to listen on port 52001 for ADIF records. So if you use 52000 in DXKeeper then enter port 52001 in the S.A.T.
Ham Radio Deluxe - In the HRD Logbook program press the Options button and select QSO Forwarding. In the UDP Receive section check the Receive QSO notification button and select the Defaults tab. Choose a port and database to receive QSO records.
N1MM - From the Config menu choose Configure Ports, Mode Control, etc. In the Configure box that opens, select the WSJT/JTDX Setup tab. In the upper WSJT-X section check the enable button. Choose a port to received log entries. The IP address can be ignored.
Log4OM - Open the configuration panel and choose Connections from the tree on the left. Now on the right side, click UDP. Under the Inbound section, enter a port and a connection name (eg SAT). In ther Service Type field choose ADIF_MESSAGE. Finally click the green plus button to complete the setup.
Amateur Contact Log (AC Log) - Under the Settings menu in ACLog, choose Application Programming Interface. Enable the TCP API Server option and set a port number, the default of 1100 is fine. Then click Done and restart ACLog. In the Location panel in the S.A.T., choose ACLog, enter the IP address for the computer running ACLog and enter the port that ACLog is listening on. (Ensure you are running version 220.127.116.11 or later of ACLog). (Also, thank you to N3FJP for making this happen)
When a satellite sets below the horizon the S.A.T. normally stops tracking (at -2° elevation) the satellite and enters idle mode. This is a safety feature to prevent unintended movement of the rotator. If however, you want to keep tracking you can click the CONTINUOUS button. The button will change to green when enabled. Now when a satellite sets, a new AOS and LOS is calculated and the antenna will move when the satellite reaches AOS. Use caution with this setting since your rotator will move again when the satellite reaches AOS.
Rotator & Rig Server
Your S.A.T. is also and Hamlib compatible rotator and rig control server. In this way you can continue to use your favorite satellite tracking program in lieu of the built in tracking of the S.A.T. (This feature has only been tested with GPredict)
In GPredict you can set up the rotator and rig in the interfaces section. The standard ports are enabled by default on the S.A.T., 4533 for the rotator and 4532 for rig. Note that PTT is not yet supported. When tracking with a PC program do not simultaneously track with the S.A.T., confusion will ensue!
If your S.A.T. is equipped with a GPS then the status panel will include a line to show the status of the GPS and a few GPS related option will be available in the Location settings page.
In the Location settings you can set the GPS ACTIVE option to one of three settings:
DISABLED - The GPS will not be used for satellite tracking purposes and the grid and coordinates you enter in the Location settings will be used.
ENABLED - The GPS will be used for tracking purposes.
ENABLED w/ AUTO GRID MODE - The GPS will be used for tracking purposes and 2 minutes after the S.A.T. is powered up the LCD will change to Grid Mode (described below).
If the GPS is set to ENABLED but it has not yet acquired a position lock the the corrdinates you enter in the Location tab will be used. Once a lock is acquired the GPS will be used.
The number of GPS satellites acquired and current grid are displayed on the GPS STAT line in the TRACK panel. The colors have meaning:
GREEN - The GPS is locked and enabled - The GPS will be used for tracking.
RED - The GPS is either not locked or not enabled - The GPS will not be used for tracking.
In the GPS status line there is a button labeled GRID. This button starts and stops Grid Tracking mode. When enabled the LCD of the S.A.T. changes to show current time, grid, acquired satellites, lattitude and longitude. When moving from oen grid to another the S.A.T. will beep three times to let you know that you have crossed a grid boundary. (A six character grid is displayed but the alarm sounds when crossing 4 character grid boundaries).
The STAT button will change the POLAR view to a GPS satellite view. The GPS satellite positions and signal strength will be displayed. Press STAT again to put the POLAR view back to normal.
