I need a little advise here. I want to test my repeater's
sensitivity through the duplexer's while the transmitter is keyed
up, into my Cushman Service Monitor. What is the best method of
doing this? Do I need an isolator of some sort, or will the service
monitor handle both the incoming

Mathew,
No, you should not disturb any of the hookups between your duplexer and
antenna, transmitter, or receiver. What I meant by a separate antenna
is one connected to the output of your service monitor, and which
radiates a signal that is picked up by your repeater antenna.
This method will
Actually the repeater is here at my home qth, only other transmitter is a
460 commercial repeater about 2 miles away, do don't think I am getting any

Forgot to mention one thing - you don't even need to visit the site
if the repeater has an autopatch (or even a remote base that is on
a different band) you can listen to the RX via the patch or remote
and let the main channel TX time out. If the quieting level in the
RX goes up exactly when the
Will give that a try tomorrow and see if it is the same and take it from
