[Elecraft] K3 filter selection

[Benny Aumala]

Fully agree with 2,7kHz and 500Hz 5 pole filters being sufficient.
Add there 6 kHz for AM and (15 kHz) FM, if needed.
And of course the coming variable  filters are interesting, or at lest 
one of them.
I think 5 was a good estimate, after all.
But this is not the end of it.

Take a KRX3 Subreceiver option and give these 2 receivers
different profile. And VOILA: a possibility of 10 different filters.
