Sorry if this is in wrong forum but here is my problem. Ever since the digital switchover (we were one of the first areas) my upstairs sky pic (from Hd box) has gone all snowy. Its connected from the rf2 out through a bypass (I believe they are known as) then to 3 upstairs t.v's . The picture upstairs on sky has gone all snowy but comes back to perfect if I unplug my roof aerial from the back of the sky Hd box. has anyone got any ideas how to sort this out cos i'm beat!! Also I have tried every available Rf channel on the sky box to no avail.

When you change the RF output channel of the Skybox are you remembering to save the changes everytime ?

Try using an attenuator on the rf input to the sky box (or remove any amplification you needed pre dso), it's possible that the increase in power at dso is now overloading the rf circuitry in the sky box and the resulting harmonics are interfering with the modulator. If you post which transmitter you are using a suitable channel for the modulator can be identified
