True but if the response curve was run manually or with an audio
spectrum analyzer like a PSK31 program, as I suggested a couple times,
that ailing filter would have been discovered. We haven't exactly
established what filters are present to know if the perceived response
is out of line. A trip to Sevierville may be premature without those
checks. Its certainly possible to have a faulty or none-standard narrow
filter.
