Operation
Once your transceiver (or your two transceivers) is configured in SAT mode (SAT engaged
from TRX-Manager) and the DDE link is selected, you may apply the following procedures.
Procedure for Satellites with fixed frequencies
If you know the single pair of working frequencies of the satellite, please fill in the interface
with these frequencies (and modes). As soon as you press the DOP button, the software
applies the appropriate Doppler compensation to the RX and TX frequencies of your station.
With this type of Satellite you should not use the VFO of your transceiver (or the other
modules of TRX-Manager) to modify the frequencies while the Doppler compensation is
activated. But you may use the Up/Downbuttons to apply small and differential
corrections (by step of 50 Hz) to the RX or TX frequencies.
Procedures for a linear transponder satellite
Such a satellite is characterized by a receive band and a corresponding transmit band where
either:
TX – RX = CONSTANT
or
TX + RX = CONSTANT (Reverse mode)
To support linear satellites, Satellite transceivers and TRX-Manager implement a Trace mode
(or Track) which makes possible to simultaneously shift the receive and transmit frequencies.
Two procedures may be used ; procedure #2 is preferable if your transceiver does not send
back its frequencies and modes to the computer (such as FT-736 or with two different
transceivers).
Procedure #1
1.
First select Trace OFF, Trsp. OFF, and Reverse if required
2.
Fill in the interface with approximate values of the RX and TX frequencies
3.
Copy the values into the VFOs (>VFO)
4.
Now, please try to listen to your signal by adjusting the VFO of your transceiver (or from
TRX-Manager)
5.
As soon as you can copy your signal (*) press Trsp. to capture the working frequencies of
the transponder. These frequencies are calculated by TRX-Manager, locked on and
displayed by the interface.
(*) if your transceiver does not send back its data or if you are using two transceivers, fill in
the RX and TX frequencies manually and press VFO> again before pressing TRSP.
Procedure #2
1.
First select Trace OFF, Trsp. OFF , and Reverse if required
