"Stay on channel 3"? If you have a cable box, you should try to
use s-video or maybe composite which are less susceptible to
interference. However, this implies that you are using RF coax
to your tuner input. If so, there is already is a hack for this
odd arrangement....

The very next item after "External channel change command" is
"Preset tuner to channel":
"If specified, the tuner will change to this
channel when the input is selected. This is only
useful if you use your tuner input with an external
channel changer."
