That's an interesting idea Red and worth a try.

At the point where you wish to place an L network, attach the manual tuner and transmitter and adjust the tuner for a good match.  Take the tuner away from the source of interference, put a 50 Ohm dummy load on the tuner input, and measure the impedance on the tuner output with the MFJ-259B.  I believe that should be close to the value of the impedance of the antenna that was measured, with little or no affect from the strong broadcast signal.>
