[QUOTE="Llew, post: 64161, member: 175007"] This sounds like tropospheric interference. If the signal strength drops for a considerable period during the day, particularly at this time of year, it could be channels from another station causing the interference, maybe an analogue one. You would need to know its identity in order to obtain the correct type of filter, but if it is close to any of your DTT channels, you might need a tunable notch filter to eliminate the offender. If all channels are affected, the tropospheric effect is probably attenuating the signal, and a filter would be of no use. An amplifier may give you problems if there are any interfering signals caused by this effect Llew [/QUOTE]
