Warren's Spectrum Analyzer screenshot of 2W out on 15m shows the 23mhz spur to be 50dB down,
which is fully compliant.? ?? ??

And there is some worrying cruft below 15m, I have no idea where that's coming from.

I don't think stretching the 20/17M filter to add 15m is going to be effective enough unless
it has a brick wall shape.? The attenuation would have to be under 1db at 21.45 and not
less than 25db down at 23.55.? That is a rather tall order.?
