we have a new sky hd box, i cant seem to get sky with the magic eye on a second tv in my bedroom, the picture is very snowy.  The instructions say i should go into settings and type 501 or something, and highlight  rf outlet, my sky box does not have that facility

I remembered that the Sky + HD has a different sequence to access the Hidden Menu or Installer Menu.

The Sky + box and the Sky box access services button then quickly press 4 then 0 then 1 then the select button then choose eg RF output number 4...

The Sky + HD box has a different setup eg services 0 then 0 then 1 then select and I found this info here:

(Also notice the far right website search TAGS links to other topics.)

Perhaps the Sky + HD customers could confirm this different sequence, please. Thanks in advance. No need to change any settings, just to check.

NB to find these recent posts, I used the forum keyword to search for the last 3 months, which is: taboo

It leads to a calculator of available RF channels according to your Freeview channels info.

Check these Google search results:

When typing in search keywords for magic eye, one of Google's suggestions was for Sky + HD:

The info here suggests that you may need to replace the existing RF2 output with a fully-shielded coax cable.

For now, test adding an extra available cable like an extension cable fitted to that RF2 output. Maybe the interference will be fixed that way or try a signal booster or amplifier to check for improvements.

If the signal is way too high, it floods the signal and may require some weakening or reducing by installing a variable attenuator, again from Satcure. So if the test cables or a booster don't work, then perhaps an attenuator will.

OK, it floods the tuner...

I will be getting Sky + HD next week.

I'm busy getting my Sky + box recordings off the hard drive so I won't lose them when the new free Sky + HD box gets installed, with a free dish upgrade as mine was installed in 2002...

I'll be able to test the various rear panel connectors and the Thomson AV sender now attached to the Sky + box scart.

The situation that Martin Pickering is referring to is of a Digital multiplex being present on the same UHF channel as the Analogue signal coming from the $KY box.
This is not actually "flooding (overloading) the tuner", (which would result in snowy pictures due to AGC action cutting tuner gain), but is simply the Digital Multiplex being seen as severe Analogue interference on the same channel.
Even a weak Digital multiplex will have this effect on Analogue reception where UHF channel allocations clash. It was a VERY substational problem back in 2001 in the area between Stockland Hill and Caradon Hill transmitters, and in certain other parts of the UK.... the broadcasters actually spent vast sums on replacing or realigning domestic aerials because of it.
