Have been receiving signal from Blackhill for years. Suddenly morning 4 July signal has become unwatchable on all channels. Signal strength normally ran about 80/90 with only occasional 1/2 bit errors. Now signal strength jumps between 0 and 80 with bit errors between 0 and 2000. There seems to be a rhythmical pattern to this 0/80 signal strength. Have tried retune and it takes a while but still picks up Blackhill. Anyone any further ideas, wondering about interference from any newly switched on transmitters close to Howood/Lochwinnoch(possibly 4G)?

Thanks Dave
Yes it is on all 6 channels(40,41,43,44,46,47) and yes it has a masthead amplifier, so not easy to bypass. Have tried another aerial, in the loft, which has built in amp (DAT45 with MRD) and get same result but lower signal strength 0/70 errors 0/2000. System is fed from a Labgear HDU681 and has worked fine for several years. This extreme range of signal strengths only started yesterday morning and is still present. Have tried retune to Darvel which used to be available to me at lower signal strength, now totally unable to receive. Seems like I get good signal for about 2 seconds then something blanks it for 4-6 seconds on a regular/harmonic basis.

jb38: Thanks for comments,yes I am using the other capabilities of the HDU681. It is used to downlink terestial and sat to main room then uplink TV + Sat & video to rest of house. The unit also supplies a 16db masthead amplifier before input to HDU681. System has worked fine since pre digital, apart from these 2 days when it was completely unwatchable. Hopefully a one off occasion!

Been having poor signal quality recently, tried a rescan and found 2 new digital channels in area CH 33 (Multiplex TSID 107c,ONID233a) and CH 36 (Multiplex TSID2011,ONID233a). Can someone throw any light on where I am picking these up from. Signal strength is good with little bit errors.
