[Elecraft] A K3 filter observation

[Ken Kopp]

Mine has 6, 2.8, 2.1, 1 and .4 kHz 8-pole roofing filters.

It's amazing that I can move from the widest to the narrowest
filter with a twirl of the "Width" control while tuned to a CW
signal ... using the NEAT "CWT" feature ... and not hear any
sign that I've (actually, the radio) has switched through five filters.

There is -NO- ringing. Impressive!
