[QUOTE="Bobben_no, post: 1157447, member: 339576"] Neumodvb also misses a transponder. "Get Spectrum" did not list 12054V at 1-WEST as a candidate to blindscan. I have done several attempts but 12054V is never listed as a candidate to blindscan. I am at the edge of one of the beams and thats why there are different power for the various transponders. But SNR for 12054V is well above threshold at 11.5dB. 12054V tunes fast in neumodvb if I manually set frequency and polarization. I am using a shell script that uses stid135-blindscan to create spectrum plot and list of transponders&parmeters. The script uses stid135-blindscan to automatically scan 10 satellite positions from my antennas continuously (cron job). So I prefer to use command line tool for that and neumodvb when I want to scan ad-hoc . I was hoping there was some way of solving this but it is not very annoying. Both neumodvb and stid135-blindscan detects 99% of the transponders as long as spectrum is not distorted. stid135-blindcan performs quite bad on 28E but I assume it may be caused by diseqc switch causing lots of reflections which distorts the spectrum. Neumodvb is doing much better and is able to identify all the candidate frequencies to blindscan at 28E but neumodvb blindscan crashes. I think it did crash on GSE data transponder 11740V SR 31419 (SNR 8.4dB/ BER 0 when I tune manually in neumodvb). [/QUOTE]
