Hi,
If you have the FM filter you do not need the AM filter for listening to AM
broadcasts with envelope detection. The FM filter is plenty good enough as
the DSP allows you to set any bandwidth you please up to about 4.2kHz audio
bandwidth (or thereabouts). This is wider than the 6kHz AM filter
Hi All
I am seriously considering a K3 and would like some advice on configuration.
My main interests, apart from the normal SSB HF and DX, are experimenting
with the narrow bandwidth digital modes. 6m would also be a new band for
me. Occasionally I like to listen to the Short Wave broadcast

The FM
filter is probably a given. I am not really interested in AM
transmissions
but do I need the AM filter to listen to the AM broadcast bands?
No; you can listen to AM with the FM filter, and
Keep in mind that the xtal roofing filters don't set the final bandwidth.
They just protect the later stages of the K3 from really huge signals
outside the roofing filter bandwidth. The final bandwidth is set by the
DSP system in the second I.F. The DSP bandwidth is adjustable over a very
wide
Hi Deane - for what it's worth.
I think for most non-critical (non-contest, non-DX) users, the K3
standard 2.7 kHz SSB filter does a good job for CW and SSB modes. The
K3 DSP software allows you to narrow the bandwidth for CW to 500 Hz or
less. The DSP works much better than the Yaesu and
