Hi David.
You can use your HT as a signal generator if that is all you have but
I would recommend a touch-up once the filter is installed, using the
RF from the exciter/PA. The wires are for the power control circuitry
that drives and protects the PA at the same time (in the case of high
SWR). If you follow the directions described on the RBTIP page you
should be able to get the filter where it needs to be. If you are
not using a service monitor with a return loss bridge, be sure to use
a high quality 50 0hm load and a good watt meter. (Read Bird or
Coaxial Dynamics)
