TBS 6903X reviews and tests

[iko]

I would be interested in your opinions on the TBS 6903X card?

After a month of testing, I am disappointed with this card.

Compared to the TBS 5927 card, the sensitivity of the tuner is significantly weaker. It has problems tuning some transponders. (Linux)
Blindscan is slow. Sometimes it misses even strong transponders. Tested via EBSPro 18.0.0.4 (Win)
It is having problems with MIS debugging (RAI 5W). I can only tune in to one stream at a time. At the next stream, it will say tuning failed. (Linux).
After locking any data transponders for example Eutelsat 16A, freq. 12507 H.... DVB-S2 TP lock, but it won't search for any stations... Only a driver restart will help...

The only advantage over TBS5927 for me is DVB-S2X support.

This normal for FBC tuners.

Fast blindscan not implemented (BLScan2). Only slow step-by-step BLScan

The TBS6903X is referred to as a PROFI card. For 400 euros, I expected more.

After locking any data transponders for example Eutelsat 16A, freq. 12507 H.... DVB-S2 TP lock, but it won't search for any stations... Only a driver restart will help...

Blindscan is slow. Sometimes it misses even strong transponders. Tested via EBSPro 18.0.0.4 (Win)
Fast blindscan not implemented (BLScan2). Only slow step-by-step BLScan

No way (near future) this option BLScan2?

tested the card on proskytv.net very stable iptv.
