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.

Screenshots:

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:

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:
Receiving Frequency: 950~2150 MHz Tuning Range
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.

The TBS 5925 has more signal sensitivity. I have four coax feeds connected to the same C band dish. The tests below were made using two of these feeds, so the antenna system is nearly identical for both tuners.

I decided to test a strong 4120H transponder at 99W.

The TBS 5925 has about 17db SNR
5925 17.3 db lock.webp

The Duo2 has about 15 db SNR
Duo2 14.9 Signal Lock.webp

Moved the dish until ALL signal was lost on the Duo2 internal tuner

Then switched to the TBS 5925 tuner without moving the dish

The TBS 5925 was able to retain a somewhat usable signal while the internal tuner lost signal completely. I think this proves or suggests that the TBS 5925 is a lot more sensitive. We pay good money for these receivers and get crap stock tuners with them!
BER works with the TBS 5925 and Does Not work with the internal tuners.


Here is a TBS 5925 16APSK Golf Feed. Very nice and clean picture

That is great work!
I have been trying to build a linux azboxme files for the tbs5922se without much progress. UDL kernel has the files ready to compile but I'm such a novice at linux it is a struggle. If possible could you talk to the image developers and see if they can incorporate all of the tbs file from UDL into the tree for future inclusion into E2 images for all boxes? Thanks.
I worked my genpix and prof 7500 into the azbox and the prof is great once the stv0900 patch is applied. The genpix needs new "codes" to be able to use all of its functions.
I am a member at Rick's as well will link two threads there that may help others with info and they may be able to help me as well.



A BIG THANK YOU TO THE PEOPLE AT RICK'S WHO WORK SO HARD AS WELL ON THESE BOXES AND FILES AND FOR THEIR INFORMATION IN THESE POSTS!!!



Thanks guys!

Enigma2 is not closed source, so the files needed to run the TBS 5925 will probably show up in many E2 images at some point in time. The information you have posted will be seen and may be useful. Thanks! EB
 
TBS5925 now available in SatdreamGr Test images. This image is available to anyone that wants to test this tuner. (Vu+ Zero screenshot shown below.)
