TBS 5925 (Based on OpenPLi) Enigma2 Support!

Now testing the TBS 5925 tuner using a Vu+ Duo2 receiver. Support for other models may follow. It also looks like changes are being made in enigma2 for support of 16apsk and 32apsk formats. I find the 5925 to be a very fine addition to the Duo2 receiver, and can say that it outperforms the stock Duo2 tuners in many areas.

Nice. Any other images working with the TBS?

No other images that I know of. This particular image is "private" or "experimental" and will not be posted by me. I expect a public posting of an image with these drivers soon.

Connected the TBS 5925 to the computer and did a blindscan of 103W Ku. EBS Pro found a 12085V SR5000 32APSK transponder. I entered most of his information in the Duo2 and got a lock with the 5925 connected. Also found another tp that the 5925 locked, and the Duo2 internal tuner did not. I really do not know if I trust what EBS Pro says but here are screenshots of the claimed to be 12085V 32 APSK tp and another tp that the internal Duo2 tuners would not lock.

Look at the new information they are adding to the satellite file:

Would it be possible to have it show the correct modulation?

These are Test images, so you will see things not being displayed correctly. I expect changes to be made before the images are released. For me right now, the main thing is it works!

How is the TBS tuner sensitivity vs. Vu+? On a weak transponder, which has better lock threshold? I am wondering if the TBS tuner is more sensitive, it would probably help with smaller ku dishes.

The TBS 5925 tuner is better by a wide margin. It locks the small 11804H transponder at 87W easily while the internal usb tuner has problems with this transponder sometimes. SNR in db is up on many transponders. Have not concluded yet if this is a real increase or artificial one.


Here are the TBS 5925 specs, which are now being realized in the Duo2:
Specifications:

Input level: -69~-23dBm
DVB-S2/DVB-S 8PSK QPSK 16APSK 32APSK Demodulator
Symbol Rate:
DVB-S QPSK 0.2~45Msps
DVB-S2 QPSK/8PSK 0.2~45Msps
Carrier Capture Range: ±10MHz
-DVB-S2 CCM ACM VCM
QPSK+1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10
8PSK+3/5, 2/3, 3/4, 5/6, 8/9, 9/10
16APSK+2/3, 3/4, 4/5, 5/6, 8/9, 9/10
32APSK+3/4, 4/5, 5/6, 8/9, 9/10
-DVB-S
QPSK+1/2, 2/3, 3/4, 5/6, 7/8

For the last year the PBS stations have been giving me problems on 87 and 125 when some of the transponders switched to 8psk. I was thinking of ordering four Winegard DS-3100 to replace my DTV Ku dishes which have done a great job for the last few years. If that doesn't work, I'll probably try the TBS once other images are available.

I used to be able to lock in 11804 without any problems last year using the DTV dish, but lately it's a hit and miss situation. Hopefully the Winegard will suffice.
