thanks for your reply and time.
This text is basically the same as posted on the very first page of this thread.
I read it several times and still found it unclear to me, sorry.
1. Lock to master signal
First, the system must be set to a reference signal (menu item "Lock" ). This is used to calculate the actual LO frequency and as master signal for the software drift correction. Default setting is the engineering beacon of Es'hail-2 (menu item "Master"). With the preset RF frequency you have to adjust the peak in the audio spectrum to 1.5 kHz.
The menu itself is hardly found by a beginner. So here we should start:
The "menu" is hidden in the SAT Controller app.
Mouse hoover over the button "Drift correction".
Then right mouse click over button "Drift correction" and keep it pressed.
Than the "menu" pops up.
Q1: The first step is to adjust to a "master signal", right? Which signal on which QRG could that be?
Q2: Which beacon do you mean by "engineering beacon of Es'hail-2" ? 10.489.500 / 10.489.750 or 10.489.900 ?
Q3: After I choose a "master signal" and corrected it to the audio spectrum to 1.5KHz, than I press "Lock", right?
The next steps I will try after we proceeded with the ones above.
Thanks for your feedback and your time. Sorry for my "look from the outside" questions, Frank!
