I'm unsure about the 20 to 30 min cycle some of us are seeing.I did see  
the the period become more random after I reduced the signal.

I have just been out playing with the Antenna orientation.I swung the  
antenna 30 degrees either side of the existing aim,with interesting  
results.I could improve the TV3 signal strength and quality by moving away  
 from pointing directly at the transmitter at the expense of Prime and  
TVNZ,but still getting acceptable results on those frequencies.The high  
frequency (TV3) is more sensitive to targeting  and pointing directly at  
the transmitter is not optimum for my location.I have left it pointing  
about 5 to 10 degrees west of the transmitter.It's not perfect but  
hopefully testing will show some improvement in recordings.
