VU+DUO2, the tuner does not differentiate DVB-S with DVB-S2, the FEC does not matter in general, if you have more than 4 tuners (including USB-DTT) it does not work. VU+Solo4K, the blind scan as it arrives, has it from VU+, but it doesn't work, the images from other devices remove it. VU+Zero4K, blind scan of the high band does not emit the tone for the LNB to go to high band, zero channels found. VU+Ultimo4K, the blind scan as it arrives, has it from VU+, but it doesn't work, the images from other devices remove it. Here I add the Gigablue with FBC tuner, from the factory it even starts the blind search, but with zero channels, when updating to more modern versions from the factory, it already works worse/it freezes and the option disappears. In general, it is seen that FBC tuners do not work with blind search, yes I already know that they sell it (they put it as a sales argument, but none), I have the 3 types of VU+ FBC tuners, remember that the last DVB-S2X V2 has the external connectors closer together and in some channels, the signal and quality indication may be missing depending on the channel you put on, as in VU+ the error indicator does not work, it is always zero, comparing the noise in the image (pixelation), It seems that the V2 tuenr beats the V1 by a very small difference. Tested the Gigablue 4K with FBC tuner (both models).I forget, using normal LNB, manual or satellite search using the transponder/frequency database (satellites.xml file), works well, but if you use unicable LNB, it will not find channels, the response is very slow, between It asks for a tp and the LNB sends it to it, it jumps to another tp, finding out of 1300 channels, only 300 and then it says that it did not find channels, perform several tests increasing the response times of the unicable LNB in the configuration (unicable. xml) without positive results. I have configured it to show errors when zapping between channels using unicable LNB to see, but I recommend that it not show it, it usually takes 1 to 3 seconds to change the channel, with the fast channel change option (FCC) you do not have this problem, but it is better to have 8 tuners configured in the program, in my case with 4 it almost never hits. Then as you use them to record channels, you run out of tuners.Regarding the normal VU+ tuner that can be DTT or cable, internally the antenna connection in the 2 double/2 tuners is one, they allow you to put DTT and cable, but when trying to save the second configuration it gives errors/blue screen similar to Windows, I have 2 decos and the image does not matter with the double tuners, as they support up to 4 USB-TDT tuners, one option is to use the old Mygica T230C, supported by driver, or the new MygicaT230C, all USB-TDT2/cable and configure for cable ( It does not work 100% due to the drivers for Enigma2, only 50% but they work). From VU+, the single and double DTT/DTT2 and Cable have been tested for years, the best in terms of sensitivity is the single (1 tuner) DTT2/cable that has the blue plate (in this case the connectors are inverted, the input signal is from below).The Octagon SF8008 4K Twin, at the moment the best for blind search, but. It no longer blocks when finding 16APSK channels but I see that with the changes in Astra 19'2ºE that this month December 2023, I see that it is bundled with the DVB-S 10758 V 22000 5/6 QPSK that I change to DVB-S2 10758 V 22000 2/3 8PSK, it sees them in blind search as DVB-S, and sees them perfectly with its corresponding clear subscription, if I manually search in DVB-S2 and delete what it already has, perfect, as I say, it gets complicated, I have to put the latest versions so what happens. Here's a note, FBC tuners do not allow errors with any data to search for channels manually, be careful that the automatic option for some parameters does not work well.The Octagon SF8008, as indicated by colleagues, does not have an IC, the side card reader works with seca and also with nagra. A note, the SF8008 mini version is almost the same guts/chip of the combo model (SAT-TDT) without the electronic part on the front, notice that the semi-transparent plastic case dissipates heat worse (but the plastic is cold ) than the metal box of the big ones.The SF8008 sat tuner is Si2166D (DVB-S2X) The Edision OS MIO 4K and its more modern version Edison OS MIO+ 4K, the tuner is Si6261 DVB-S2X, it is more deaf than the octagon, I was able to evaluate the Edision OS MIO 4K with the same antenna and another companion, the MIO+ 4K. With the channel fished from another receiver, the list loaded, SR1481 costs you and SR 1300 is nothing. Carrying out tests on Eutelsat10A at 10ºEast where we have 11011 V 1200 3/5 DVB-S2/QPSK, Dzair TV. You tune it, but you can't see it, you open the channels, but you can't see it due to the pixelation it has.The Octagon without problems. Regarding the modification of the steps to scan in these receivers, it is not worth it in these receivers, they have a bandwidth of 4Mhz, to tune 2 channels at less than 2Mhz you have to look for the first -4Mhz and the second +4Mhz, yes You have 3 frequencies, only 2 right. Testing 1 year ago on Eutelsat 8 West B at 8.0° West (W).Tenemos 2 TP/Frecuencias.12620 V SR890 DVB-S, esta sin problemas, salen canales de radio.12621 V SR468 DVB-S2, esta se sintoniza sin problemas, pero al buscar canales, no encuentra nada, ojo que se tira 3 veces mas buscando, pero luego no muestra nada.<img src="https://i.postimg.cc/YqzY48JZ/Frecuencias-juntas.png" alt="" class="fr-fic fr-dii fr-draggable " style="" />With normal LNB, as many channels as have the 8 Tp/frequencies of the same band, polarity and satellite. With a single LNB and an FBC tuner, as many channels as the 8 Tp/frequencies of the satellites that are connected to the tuners have, 16-18 recordings to the hard drive, the receiver is slow but works well. With FBC tuner, you can use an external port A and connect a single cable, serving tuner B (through internal loop) and also the internal CDEFGH tuners. With 2 FBC boards, you need an external 2-output splitter/distributor with power supply to provide service/signal to the second board, to tuner I (J internal connection/loop).The tested mixed unicable LNBs of 4/8/16/24 unicable and normal 2/3 outputs depending on the model. Since I like to test decos with FBC tuners, to see if they hold up to recordings on 2.5" 500GB and 5400rpm disks (GigaBlue 4K/Qviart linux3 4K), they all held up to 8 TP's and 16 granations. If you can, it is more comfortable to run a second cable to another satellite and be able to have 4 tuners for each satellite, with the DiSEqC you only have 4 active tuners, losing the other satellite.They sell the Inverto programmer and tools were also implemented from the Enigma2 receiver to carry out this programming more cheaply with commands, remember that unicable LNBs are more expensive and more deaf than normal ones (up to 0.7dB noise figure), yes It's no problem, perfect, I downloaded a cable for each satellite.Summary: 2 satellites, up to 4 satellites and distribute the 32 communication SCRs available in the programmable single cable LNBs, then they are joined using a splitter of 2 (satellites) or 4 (satellites) for this reason a little more loss, lower a cable to the receiver. In the receiver, the tuners are programmed with the satellites and the SCRs that that satellite has.VU+DUO4K SE.- Supports 2 FBC, SAT/DTT/Cable tuners, if they are sat and tdt, they have a specific position, they cannot be exchanged. IC and card readers, 2'5" larger disk size in cady (<10mm which is the standard in 2'5"). VU+Ultimo4K (a bit less powerful), supports 3 tuners. 2 FBC tuners, SAT/DTT/Cable 1 normal tuner, single/double satellite, single DTT/cable. 2'5" or 3'5" internal hard drive, the last verified 12TB, has 2 ICs and 2 card readers. In general, these VU+ decos support 4 tuners (vtuner from 0 to 4) to install USB tuners, depending on the image installed, the USB-DTT/cable are installed automatically, older models have to load general drivers. Note: I would swear that with Multistreaming you sometimes get involved with the PLS data, but using channel lists from a partner, if you entered the data when searching for the channel or the data is correctly placed in the satellites.xml file, these channels work fine.Apologies for the translation and being late.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite14" alt=":-doh" title="DOH!    :-doh" loading="lazy" data-shortname=":-doh" />.</blockquote>
