[mythtvnz] DVB-T signal strength

[Steve V]

I am receiving DVB-T signals using the same card no problem.

My signal strengths vary from around 52% up to 78%. Even the 52% are good and stable.

If I have the amplifier off and scan I only pick up the TV3 C4 transmission, with the amplifier on I get TV1 and TV2 as well.

Thanks for that, I forgot to say that I do have the following line in my 
/etc/modprobe.d/options

options dvb_usb_dib0700 force_lna_activation=1


What signal strength readings are aqequate for DVB-T reception?  

This assumes that interference isn't a problem.

I would like to guage how much work I have to do to improve the signal..
