Hi
I am setting up my new Tm-Nano-3T on terrestrial
Working but for HD breaking up occasionally.(pixilation).
My terrestrial Ariel setup was pre-switchover, high gain Televes DAT75 Ariel, with MRD (powered head amp), feeding a powered house distribution box.
Post-switchover the transmitter power went from around 800 watts to 2+kilowatts.
Now the TV and the other receivers show 100% signal. the TM-Nano-3T shows SNR: 99% , AGC: 54%, BER: 0%, on all but the 3 HD channels (21,32,34).
On The 3 channels with HD content (21,32,34 from Sandy Heath) the TM-Nano-3T shows SNR:0% jumping to 99% , AGC: 54%, BER: 0% jumping to 12000%, it looks really horrible.
At the same time I get no pixilation on the BBCHD.
I feel I need an attenuator (on order) due to the 100% signal level.
MY QUESTION:-
What signal levels do other users of the TM-Nano-3T find give an acceptable / reliable picture on terrestrial reception.
I.e. how much can I turn down the signal without causing a problem.
This information may be useful to others experiencing problems with terrestrial reception.
Thanks Chris

to get signal information tune into required channel , Menu/setup/service searching/sat finder, gives signal graphic.
