[Elecraft] [K3] Variable filters? And what filter is best for AMbroadcast reception?

[Craig D. Smith]

Good Morning Thomas ...

The variable BW filter concept was pitched early on - before the K3 was
first produced.  But nothing has come of it, so don't hold your breath.
Even if it does materialize, it probably wouldn't cover an extremely broad
range, such as 10 KHz to CW widths.

So go ahead and purchase either the 6 KHz or the 13 KHz for SW and BCB AM
listening.  For this purpose, the 13 KHz is better as you point out.  That
is what I use.  But if you plan on transmitting on AM you will need the 6
KHz filter.
