What's new: Vers. 12.8c 1. The CAT commands for the IC-9100 have been expanded. The program can now activate the digital mode of the radio. The mode entry in Doppler.SQF for this function is FMD. 2. The top line of the SatPC32 frequency display shows the ground station's downlink and uplink frequency for the chosen satellite, adjusted for the current Doppler shift. The bottom line displays the Doppler shift of the downlink and uplink. It is now possible to switch the bottom line to display the downlink and uplink frequencies at the satellite instead of the Doppler shifts. The setting can be toggled and saved in the "Mode" menu. The new feature is helpful - for example - if users want to specify the frequency for a sked over a linear transponder. They can agree to a downlink frequency at the satellite and tune their radios to that frequency via the VFO knob or the 5 up/down frequency controls. The program will then automatically set the correct uplink frequency if the Doppler correction mode is set to "uplink + downlink" in the "Mode" menu. While automatic Doppler tuning is engaged, the program will hold the chosen uplink and downlink frequencies constant at the satellite. Both users will hear their partner (and their own downlink signal) without needing further frequency adjustments. Also, the feature allows users to easily specify and save a starting frequency, for example 10 kHz above the center of the passband. 3.Remote control programs, for example LogMein, allow remote control of SatPC32. Previous SatPC32 versions didn't provide a "PTT" button, so the radio couldn't be switched between transmit and receive via remote control. The new SatPC32 and SatPC32ISS programs provide 'PTT' buttons which can be displayed or hidden via double-clicking on the status bar at the bottom of the program window. The PTT buttons are located close to the other program controls. 4. Keps files for different types of satellites can be merged to a single file. For example, the Celestrak "amateur" and "cubesats" TLE text files. That allows users to add diverse satellites to the same group (SatPC32 menu "Satellites") and to see them on the world map or in the "Count Down" window without switching groups within the program. The merged Keps file can also be used with the other programs (Wisat32, WinListen, WinAos). With older program versions a problem occurred if a satellite had data in two or more of the merged files. 5. WinListen now displays azimuth and elevation values in 0.1 degree increments. That is helpful if the elevation of the satellite pass is low, causing the elevation to change very slowly. Also, the maximum possible distance between two observers that allows a contact over the satellite is given when the satellite is close to the horizon for both of them. 6. Minor improvements a. Some older fonts in the SatPC32 and SatPC32ISS have been replaced by fonts that are more readable. b. The function that switches the sub tone frequencies for ICOM radios has been improved. Previous program versions switched the bands to get access to the uplink band. The new version avoids this by using other CAT commands. 7. Bug fixes a. The sub tone frequency setting function for the Yaesu FT-857, FT-897 didn't work. That has been fixed. b. CAT control of old Kenwood radios (TS-711, TS-811) didn't work properly with the Kenwood CAT interface IF-232c which requires hardware flow control. SatPC32 works without flow control. Hardware flow control can now be simulated by checking the option "RTS+12V" in the "Radio Setup" menu. c. The TS-2000 didn't correctly change into satellite mode when CAT control was activated (C+). Now it works.
