The filter for out-of-band interference is now going into production at
MFJ, a pilot run of 50 is complete.
I have no idea of the cost, but the model is a MFJ-731, it's called a "SWR
Analyzer filter" (patent pending).
It cover 160 meters in three bands, 80 meters in two bands, and 40 meters
up to ten meters in one band. It includes an adjustable notch, and is
almost perfectly transparent on the operating frequency while providing a
bandpass- band filter with a deep adjustable notch in the AM BCB.
