Hi Graham
Thanks for a quick reply. The problem was CH 27 Sandy Heath was causing pulsing on my SAT/TV distribution Amp. For some unknown reason sky boxes which are fed by the same system are not having problem. Humax is the only one. I will have to wait till next Wed for the 2nd DSO then I can attenuate the Aerial Signal. I have a 1 metre dish with good enough signal and thats why I could not understand why the problem. It started on 30 th when BBCA started up at 180 MW strength. I have a masthead 25 db amplifier. I will have attenuate by at least 20 dbs as I can not reach the aerial anymore. Age is catchiung up.
Thanks again.
