Hi Don,
The JPS ANC-4 is similar to and preceded the MFJ unit. It lacks the 'Peak

null was sometimes difficult.

All,
An active noise cancellor such as the JPS ANC-4 may
really help. You have to stop or minimize the noise before
it gets in to the radio.
Place the ANC-4 sense antenna as close to the offending TV
as possible and then adjust the controls for best noise
reduction.
