d. Entering Satellite Frequency Data

Satellite frequency data is used by SatPC32 to tune your radio. This information is stored in the Doppler.SQF file 
located in the SatPC32 program directory. This is a text file and you should follow the same procedures to modify it as 
you would use for any other text file.

In the Doppler.SQF file you will find satellite entries in the following format using SO-50 Mode V/U mode as an example:

SO-50,436795,145850,FM,FM,NOR,0,0

Satellite Name - Name matching the name in the Keplerian Elements file
Downlink Frequency - True frequency in KHz on which the satellite is transmitting
Uplink Frequency - True frequency in KHz on which the satellite is receiving
Downlink Mode - emission used for this satellite on this downlink frequency
Uplink Mode - emission used for this satellite on this uplink frequency
Tracking Mode - whether the uplink and downlink frequencies track in normal or reverse mode
Downlink Offset - downlink offset in KHz (see Section 5 below)
Uplink Offset - uplink offset in KHz (see Section 5 below)

Do not use commas or periods to separate thousands values as these will be interpreted as a parameter separator. Only 
use a decimal to enter fractional kilohertz.

This information is used by SatPC32 to initially set up the frequency of the radio. If the mode is single sideband (SSB) 
the frequency is only a starting point, and as you tune your radio's downlink frequency SatPC32 will adjust your uplink 
frequency accordingly. If the mode is FM SatPC32 does not allow you to change the radio's downlink frequency since this 
is a fixed value. (Note, in FM mode you can still fine tune your receiver using your radio's RIT control.

You can have as many entries for a satellite as the satellite supports. For example, AO-7 has two modes (B and A) so it 
has two entries:

AO-7,145948.8,432149.4,USB,LSB,REV,0,0
AO-7,29450,145900,USB,USB,NOR,0,0

SatPC32 will use the first mode entered as the default mode when the satellite is selected, so in the case of AO-7, it 
will default to Mode B. If you need to use another mode select it by using the CAT menu item and select the mode you need.

If you are only using SatPC32 to tune a receiver you can enter 0 for the uplink frequency. If you are only using it to 
tune a transmitter, enter 0 for the downlink frequency.
