Whew! The last week has been a tidal wave of interest, orders and questions.
There has been a lot of discussion and speculation on the list lately
about the necessity for narrow filters ahead of the K3's DSP filtering
and the impact of various filter bandwidths on receiver IMD. This in
turn is

Thank you Eric! Sorry for being paranoid but
the old axiom "Fool me once...shame on you. Fool me
twice...shame on me." applies to me personally since
I have been burned before...hence my caution.

>Notes:
Since we also transmit through this (2.7 kHz) filter...
Will it be possible to transmit CW through
a narrower filter than the 2.7 kHz to even further
minimize transmitted key clicks and phase noise?
If so, how low in BW could we go before causing
problems? 1 kHz, 500 H
WA6HHZ explained "We chose INRAD as our OEM 8-pole crystal filter
supplier because of their excellent filter performance."
I hope Elecraft will consider offering the Inrad 1.8Khz 8-pole filter
8.215Mhz if (711-B) for the K3, or even something narrower, for ssb
contesting. I assume the K3 will be
Bill,
Setting the TX filter for CW is a menu config option. I'm
not sure what testing as been done yet to outline the TX
characteristics of the narrower filters though.
