AGC Signal changes dramatically between channels
 

What is the AGC signal? What is it's purpose?

Some channels it will be really high like say 61243546 then I can change channel to say UK Gold and it will be low, something like 10.

Why the irratic change?

AGC stands for automatic gain control. In an application such as a STB it would typically be there to control the gain on the front-end RF amp which is fed directly from the cable feed to your STB. The reason that the that it is different dependant on what channel your watching is that one TV program' carrier signal may be one strength whilst another program may have a carrier at a different level. The AGC works to even out these differences so that the signal the decoder/demodulator sees the same signal strength no matter what the STB is tuned to.

Thank you very much for the information, i thought there was something wrong with my signal strength.

Thanks for putting my mind at rest.
