PL encode on CAS/RUS only. If you want to
remove the PL tone out of your repeater when there is not an active
signal then this is an easy way to do it. I use this on a split site 6
meter repeater on the uhf link TX. It prevents the cwid on the link TX
from being heard in the far end (most of the time). |
