The TBS-6903 has two tuners and demodulators to pick out the exact frequencies. Two instances of the tellicast client must run of course. This works fine under Windows and GNU/Linux. Regards Ernst

Re: FY-3D
Sorry David,I did not have any files as I was not taking the satellite
data as I had no way of using the data in windows. I will start taking data tomorrow for one day, so I have files available. Regards Ian. ======================== Ah, OK, I hadn't appreciated that you didn't have the data! Good luck with the Python stuff. As Python works on Linux it should work on Windows with very minor tweaks.

Re: FY-3D

maybe you asked for some more precise information like this (taken from one of my FY-3D PyTROLL/SatPy processing files): # File Pattern : {platform_shortname}_{start_time:%Y%m%d_%H%M%S}_{end_time:%H%M%S}_{orbit_number:s}_MERSI_1000M_L1B.{ext} # File Pattern : {platform_shortname}_{start_time:%Y%m%d_%H%M%S}_{end_time:%H%M%S}_{orbit_number:s}_MERSI_GEO1K_L1B.{ext} # Example name : FY3D_20200429_011200_011300_12719_MERSI_1000M_L1B.HDF # Example name : FY3D_20200429_011200_011300_12719_MERSI_GEO1K_L1B.HDF # Hugo's ruler : 0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012 # copied EMCV : 0 1 2 3 4 5 6 7 8 9 10 # EUMETCast : These files arrive as above in channel E1H-RDS-2 (HVS-1) Best regards Ernst ======================== Thanks for both pieces of information.

The segments where we see the black gaps pretend in their file names to be the standard length of app. 85 seconds. But their size is often only 50% of normal segments. For FY-3D half of the pass over U.K. is simply missing. It's not disseminated. Documented for OPS on 3 orbits each. Regards Ernst

Re: Eumetcast Tuner
Hello
I would like to by Eumetcast Satellite receiver . CAN be any suitable device I loose my second processing unit during thunderstorm Br. Esko Petäjä ------------------------------------------------ Esko, Sorry to hear that! I don't associate Finland with a high thunderstorm risk. How did the device fail - was it through the power connections, network connections, or the RF input? I know that some people have had power supply failures (overheating?). If the failure was through the RF connector perhaps there's a lightning arrester you could fit? These should be easily available for the F connector used in satellite TV, but check they are rated for up to 1.7 GHz (satellite TV could be up to 2 GHz). 73, David GM8ARV -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email: david-taylor@blueyonder.co.uk Twitter: @gm8arv

Re: Double tuner in T1/T2
Hello
I am just updating my systems. Is it possible to use double tuner capability of devices to receive from both transponders T1/T2 with same card. ?? TBS-6903/6908 or SR 1 Br. Esko Petäjä ============================== Esko, Yes, I'm using a TBS6903 PCIe card in a PC receiving both T1/HVS-1 and T2/HVS-2 (likely it would do BAS as well but I have no need in that PC). It's in the single-cable configuration. Works well, but the TBS IP reception software continually crashed that Windows-10 PC, so I use BDADataEx instead. It doesn't stretch that PC much - it's receive-only supply a limited subset of HVS-1 data (GOES-16/17 and Himawari) over the house network. https://www.satsignal.eu/mrtg/performance_lund.php SR1 - one transponder only. 73, David GM8ARV -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email: david-taylor@blueyonder.co.uk Twitter: @gm8arv
