I'm a little confused....Are you saying that eventhough the display says
10kHz, it's really not unless you have the FM filter and if it's not 10kHz,
then what is it if I use the 6kHz filter. If it's really not then why
display it?

Subject: [Elecraft] K3 FM filter required for full AM receive width
Windy,
The stock K3 comes with one 2.7khz filter and that's a
hardware limitation.
The firmware cannot help this.
So, you will need a 5.0 filter (AM), a 13 filter (FM),
or one of the variable hardware filters that should be
available in the next couple of years from Elecraft.
I use the FM filter and it may also be usable in AM
transmit. I know its good for FM and SWL.

Wayne,
In the new firmware announcement you say:
AM RECEIVE WIDTH RANGE INCREASED
...
NORM selects an IF bandwidth of 6.0 kHz in this
mode. WIDTH settings
above 6.0 kHz will not be useful unless you have an
FM-bandwidth
crystal filter installed (at FL1).
I like using the K3 for shortwave listening. I would
rather not be
required to buy the FM xtal filter to get the full
bandwidth on AM.
Will this change with future revisions?
