Hi Davidwf My set up works for me, these twin TV amps don't boost the signal that much, even with mine its only 83% max signal strength. As Graham said 100% would be to strong. That's why I said its trial and error go for the cheapest option first. But your right it should not be like that, but for me my Humax 2000T is a good reliable box. But if your not happy with yours then I would go for the Panasonic PVR a bit more expensive. But bearing in mind it only as HDMI output only there is no scart connection. But for what I gather it as good reviews.
The major issue is that as the signal strength increases to a level that clips the signal peaks the indicated signal strength can actually fall. The carrier distortion produced gives highly inaccurate signal strength readings.
