Ian,
Since I don't have a network analyzer or a tracking generator, I have
consistently used the S meter method to tune my cavities for both the transmit
and
receive side.
It is not recommended to tune duplexers with power applied, because you wind
up getting little arcs that leave black
I think Ralph hit the nail on the head on this one! All of the major
duplexer manufacturers ship their factory-tuned units with a warning
that reads something like this: This duplexer has been carefully tuned
using precision laboratory instruments, and no further tuning is
required before
