Today I calibrated my receiving unit - the spectrum became free of interference and non-linear distortion of the amplitude-frequency characteristic.
Compare it with the spectrum of the CrazyScan, which with step 1 MHz was recorded in 95 seconds (6 seconds longer than IQmonitor Pro), and a normal blind search took 2005 seconds and found only 35 transponders:
The usual BlindScan from IQmonitor Pro took 386 seconds (5.2 times faster), and locked 40 transponders (5 more).
IQmonitor Pro detected 41 transponders in total:
At the same time, the quality of the spectrum and its resolution are higher, and the parameters of the locked transponders are determined more precisely and are read more clearly.
CrazyScan in BlindScan-2 mode, which is not available on all PC cards, ran 4.8 times faster, but found only 39 transponders, and their symbol rates, as always, are not accurately determined:
The choice is yours
CrazyScan in BlindScan-2 mode work 95+77= 172 sec :
IQmonitor Pro 220.127.116.11 found 41 transponders from 86+53= 139 sec :
Comparison of "blind search" of transponders in simple modes BlindScan , which is supported by most PCI cards,
and BlindScan-2, which is faster but supported by fewer cards.
When receiving a satellite at 39°E using CrazyScan and IQmonitor Pro.
The search parameters (frequency step) were chosen to be the same (6 MHz) or the closest that both programs allow.
CrazyScan frequency step=6 MHz BlindScan Time= 15+209=224sec Transponders found 22, locked 22:
CrazyScan frequency step=6 MHz BlindScan-2 Time= 15+189=204sec Transponders found 27, locked 21:
CrazyScan frequency step=10 MHz BlindScan Time= 9+123=224sec Transponders found 21, locked 20:
CrazyScan frequency step=10 MHz BlindScan-2 Time= 9+148=157sec Transponders found 26, locked 22:
Frequency step more than 10 MHz cannot be set in CrazyScan
IQmonitor Pro frequency step=6 MHz BlindScan Time= 17+117=134sec Transponders found 22, locked 22:
First, compare the shape and quality of the spectra, and then remember that the scanning speed at a step of 6 MHz in the IQmonitor Pro program is 1.67 times higher than CrazyScan in the BlindScan mode, and 1.52 times in the BlindScan-2 mode
IQmonitor Pro frequency step=12 MHz BlindScan Time= 17+33=50sec Transponders found 22, locked 22:
Remember that the scanning speed at a step of 12 MHz in the IQmonitor Pro program is 4.48 times higher than CrazyScan at a step of 10 MHz in the BlindScan mode, and 3.14 times in the BlindScan-2 mode
