Here is how I check I'm not receiving Es'hail-2.
Provided that you're 'on frequency' (i.e. you know the LO frequency/frequencies of your RX-chain. Can be checked with e.g. a Baofeng tuned to 446.085 MHz) the following procedure may prevent fooling yourself.
Information is now that the 10706 MHz EB is 'vertically polarized', i.e. it is received stongest when the LNB is in vertical mode.
The following situation / sequence of events is assumed: The LNB is in V-mode (12-13V), a RTL-SDR (or similar) is used to receive the IF-signal from the LNB and one looks at the waterfall while pointing the dish 'ins Blaue hinein' while 'suddenly' a signal (around) 10706 MHz is observed.
Align the dish for max signal and also tweak the skew of the LNB. The skew angle is counter clockwise where I live. When your longitude is >24 degrees (IOT slot at the time of this writing) the skew angle is clockwise.
Zoom into the signal until you have <10 kHz frequency steps in your waterfall.
Place your hand in front of the LNB. The signal should disappear. If not, it may be a birdie (and hence you're NOT receiving Es'hail-2 ; -)
Put the LNB into H-mode (applying 18 - 19V) .. OR.. rotate the LNB 90 degrees counter clockwise. If another signal ca. 2,3 kHz lower in frequency appears, you are NOT receiving Es'hail-2 but ArabSat 5A at 30.5E instead.
