Problems With Symbol Rate ~ 45000.

[Rittberg]

I cannot receive the "HD Test promo" on Express AM1 @ 40.0°E - 10981 V SR 44951.

It is OK with the STB Humax 1000.

 

Is it a TT 3200 problem?

What do you mean by "cannot receive"? No signal when tuning to this transponder?

 

The TT 3200 tuner should theoretically be capable of catching SCPC/MCPC signals with symbolrates up to 45 MSymb/s (up to 30 MSymb/s for DVB-S2). Probably 44.9 is too close to _theoretical?_ maximum. Or it is just a driver issue...

 

I suggest you check back with the original TT app to verify whether the tuner locks on this frequency with the correct settings and get in contact with TechnoTrend otherwise.

When scanning with the Humax 1000, I receive 23 channels. Scanning with the TT 3200 using the TT app or Transedit I get sometimes nothing or sometimes 5-7 channels under the "service" name but it remains black.

Try the analyzer of transedit and check the column for missing packets. Please report the data rate (right lower corner).

 

It seems that you get a lock but the chip set of the TT can't cope with the very high muxrate. BDA normally gets the entire multiplex with software filtering of the corresponding PIDs. Some drivers allow additional hardware filtering on the card, which will solve this problem. Dunno about TT..

 

I can't receive this transponder but on 53E (Express AM 22) there's a similar transponder with such a high SR (11044V, 44950). Neither my firedtv, nor the pinnacle dvb-s2 usb2, nor my old nokia 9600s will lock. The only tuner/demodulator that locks is my old SS2 but for watching the programmes I have to use the hardware filter option.
