    you can't use a unicable lnb on a motorised setup.

    Oh dear dam now I'm really buggered. Guess the only dual sat tuner I can by is VU SOLO SE V2 which has one input and loop out

    That wont work either.

    To record two channels from two different transponders (on same device) you need either:

    • Two independent/direct/(i.e no splitter fitted) wires direct from conventional LNB to two satellite tuners.

    • A unicable LNB with a splitter and wires connected to the two tuners on the same device

    If you have the motorised dish and just a single cable, use a Universal LNB. Plug the cable into socket B of the Solo2 and configure the motor. Link internally to tuner A. Tuner A will work for transponders on the same sub-band and satellite. This mean tuner A will be severely crippled.

    Or if you are limited to one dish, point it at 28E and use the Unicable LNB. Connect the cable to socket B and link internally. No splitter needed.

    Or do it properly and get 2 dishes, one for 28E (with Unicable) and one for motorised.

    Yes I know, but as u have mentioned Unjcable will not work with motorised system.

    So the Solo se v2 is the only box I can use but obviously not full dual recording with limited function.

    Or I could go for VU+SOLO 2 and use one tuner and internally looped from B to A on a temporary basis and accept limited dual tuner function, until next summer during good weather I can have a go at re-cabling

    Loking at the specs between both of those receivers the only diffence is twin tuner function and internal hardrive capability both on the solo 2

    When u mean Tuner A looped form tuner B will be crippled you mean limited function or damaged?

    You can split cable and terrestrial without loss of features, unfortunately you can't split satellite.

    What makes you reach this conclusion? All twin tuner receivers can do this withone cable connected. The cable with no wore must be configured correctly. You need to connect wire to tuner B.

    Reading between the lines, being able to connect the satellite wire to two devices (TV being the second device) is a must fro you. In that case you can use a splitter that stops voltage going between devices. Voltage must go from one device to the LNB. Only this device will be able to send commands to the LNB. All other devices will not know they cannot control teh LNB and you will get tune failed if tehy attempt to tune to a service that is not on the same quadrant of servces that a standard LNB can tune to.

    A standard LNB can tune to horizontal, vertical, high and low planes. It switches mode when voltages are sent to it.

    I wonder, is the Et8500 near this apparatus. If so, why not just use that instead of getting a new receiver.

    Specs don't tell the full story. Solo2 has a much more professional finish, and a front display. I've had both and much prefer the Solo2. And internal HDD is a massive plus.

    Thanks, that makes things a little clear although I have noticed signal degradation when I split my ET8500 PVR (3 X dvbt2) and the in built tv freeview tuner.

    You may need an attenuator?

    I have a ET8500 but only use it as Terrestrial PVR (3 X dvbt2).

    I prefer the VU+ as sat receiver due to its support and development and features. Currently I have TM6800 hd supper using CCAM WITH usual problems of freezing and stutter, I guess the box was never designed to handle that.

    Hence the preference for VU+ as it can handle CCAM better being LINUX and plugin options.

    So my only hurdle like everyone mentions I need 2 cables or setlle for one on a temporary basis until I getthe chance to try and re-cable. I understand I can not use Unicable as I have A Motorised system.

    Possibly I assume that regulates or increases the signal?
    All the pictures are fine but I can see lower signal bar on my in buit tv tuner when the ET8500 is switched on and recording other channels.
    Quality of the dvbt2 tuners on the ET8500 appears better than my Samsung KS9000. Both devices are split via aerial splitter. Apologies from moving off topic here.

    An attenuator is used to reduce the signal if it is too strong.

    Sounds like the splitter you're using isn't helping matters.

    I use a 4-way variable gain signal booster to feed dvbt2 tuners independently, but a better quality splitter might be all you need.

    I'm sure someone on here will soon advise.

    ps. For me, Freeview signal quality is very variable at the moment due to weather/atmospherics, so now might not be the best time to be comparing signal levels.

    Satellite set top box and Freesat receiver in TV = two satellite devices. As you intend to have two tuners on the satellite set top box, that is three tuners.

    The answers to your questions have been given. Weather is still fine for you to run cables. I don't see the point in looping out/splitting to the TV satellite tuner apart from "not having to update settings" (a moot point if using ABM). Even if recording, your set top box can display the channels.

    Note/Polite request:
    People use question marks when asking questions. Your usage is out of context. It is difficult to understand whether you are asking a question or making a statement! Please only use the question mark when you are asking a question.
