but cxd2820 report correct SNR, RFLevel values (strenght), so can be used for some Strength/Quality calculation. for example my implementation in StreamREaderEx-BDA + TSReader proxy source: http://crazycat69.narod.ru/sattelite/scan/Terrestial/DVBT-554.png Reception of DVB-T2,256QAM,3/5 Strength=SNR*...

i can confirm - this common problem for all CX23883-based TBS PCI products (8910, 8920, 8921, 8922 and OEM). Look like driver init GPIO lines on start and not restore it on wake-up. Maube CX23885-based PCIE products also have this problem (need test), but modern SAA7160-based not have this issue (RC...

- 12,585 GHz, pol. H, SR: 27500, FEC: 2/3 (DVB-S2/8PSK), PLS Mode: Root + 8, MIS 1 (data transmission, OpenMux IP Gateway) - 12,669 GHz, pol. H, SR: 29900, FEC: 2/3 (DVB-S2/8PSK), PLS Mode: Root + 8, MIS 1 (data transmission) This is DVB-H - some Multicast low-resolution IPTV for mobile devices (IP...

This common problem for dual demod IC's (6984 use 2x dual demod CX24117). If you want good performance at high bitrates (SR>30000Ks) - need use only one demod path.

what ambient temperature in your PC case ? maybe hot GPU card close to 6925 ?

anysee t2c use same samsung NIM with tda18212/cxd2820r (also used in tbs6220), now supported in linux drivers :) so possible replace proprietary tbs tuner-demod driver with open-source :) anyway this diffrent devices, but look like cypress fx2 used in both :) Llattice PLD implement some CI controlle...

encoded EPG ?:) some new but TV stay FTA ?:)

in my soft/drivers i offer different Level/Quality calculation: 1. Technotrend-style: Level = SNR*5, Quality = f(BER): if (!Locked) Quality = 0; else if(BER < 10e-5) // <0.0001 Quality = 100; // 100% else if(BER < 10e-4) // <0.001 Quality = 80; // 80% else if(BER < 10e-3) // <0.01 Quality = 60; // 6...

this usual DVB-S2/8PSK transponder at 13E - 12360,H,29900,3/4
single-stream, can be received with any DVB-S2 device

this very old CrazyScan, not have 'update modulation info' option.
please update CrazyScan + StreamReaderEx - http://sourceforge.net/p/crazyscan/wiki/
