I just set my old dish up as a second dish (fixed) for my dm8K, the main dish is motorised.

I've initially pointed it at 28E (Astra2) and thought I'd compare the signal strength between the two dishes.

My motorised dish shows at 87% on Channel 4, the fixed dish shows at 100%.
The problem I'm getting is, when I have the fixed dish attatched the signal seems to drop out intermittently on both Tuners, it seems as if the box can't cope with a signal strength of 100%.
If I disconnect the dish (or set the tuner to 'nothing') then all is well and I have no dropout of signal, but as soon as i reconnect I get the signal dropout problem again, where the picture goes 'blocky' for short periods of time.

Is this a problem with the dm8k?

Has anyone else come across this?
