Hey guys, new member here, this is gonna be a bit long ...

So in my house (or my mums house, whatever) we used to have analog cable with 2 decoders, one in the lounge all by itself, and another in one of the three bedrooms that would go through an old vcr that would then output the reception through a splitter to the other 2 bedrooms, somewhere along the line the roof antenna would somehow merge with this reception and give these 2 bedrooms whatever the decoder was set on and the fta uhf/vhf stuff, all was good, but prime was a little fuzzy ...

Then just yesterday we got our 10+ year old decoders replaced with new digital decoders and we have the lounge decoder setup the same way as the old analog, but in the bedrooms we have the decoder that sends out the fta channels and whatever channel the decoder is set on thorugh the back rf output set up so it splits the signal to the other 2 bedrooms so we have tv there with (hypothetically) better reception! But i have one problem, the channels are quite fuzzy, with what i would describe as "texture" in the image. Is there any way to clear up this reception with like a booster or something so it doesn't look as grainy?

Thanks in advance.

The feed you are using for the other TV's is analogue. It will look bad compaired to the digital feeds that you get out of the digital STB but then you are getting it for free so you will just have to put up with it or get yourself some freeview decoders for the other TV's.
Also once Telstra get rid of their analogue service then those channels will be removed anyway.

O dam, so you're telling me the RF output will be useless when they get rid of analog? If so, dam!

Thanks for the advice.

Maybe you can be slightly more specific and say whether the fuzzy channels in question are TCL analog channels arriving via cable or terrestrial analog channels arriving from your antenna which now are subject to interference. Maybe disconnect the decoder to determine if you are unsure.

TelstraClear's digital decoders are sad enough with only composite/svideo out but to use the RF out for anything is a sad day in paradise indeed.

Lol sad day in paradise

All the channels that i say are fuzzy are the rf output ones, i'm sure they are because 1-2-3 are all letterboxed widescreen, which is the main reason i have it set up that way as opposed to tuning into the roof aerial that also somehow joins up with the cable feed to the 2 other bedrooms. I really need to crawl under this antique of a house and figure out how the hell the tv is wired up.

You may find that the analog channels off the antenna are better quality than Telstras analog collection. You don't say which city you reside in, but if you are in a cable area in Christchurch you most likely get analog terrestrial in reasonable quality (with appropriate antennas) and also have access to DVB-T transmissions which are vastly superior.

The channels on the RF out are the analog cable channels, chances are the levels are too low once they have been thru the box and your additional cabling, and putting amplifiers on it is an invitation for trouble as it would be amplifying everything on the cable.

Who knows how much longer the analog channels will be there for - so investing in resolving the problem may just be a waste of money.

Ok, I've just remembered how i had it set up before so i'm going to go back to that when they switch the analog channels off.

Thanks for all your help.
