[Elecraft] Considering K3

[Dick Dievendorff]

I'd recommend the 400 Hz over the 250 Hz 8-pole filter if it's your only CW
filter.  This is the roofing filter; you can still dial the IF bandwidth
down (to 50 Hz) for more selectivity.  If you have the budget for an
additional CW filter, the 200 Hz 5-pole might be a good second CW filter.  I
have the 400 Hz and 250 Hz 8-pole filters, and there isn't really that much
difference between them.

The 6 kHz AM filter is required for AM transmit (and it's also used for
ESSB, should you choose to use ESSB).  The 13 kHz FM filter cannot be used
as the AM transmit filter at this time.

I am also considering a K3, and I really enjoy reading all the comments on
K3
owners' experiences and preferences.

I am planning on ordering a K3 at Dayton this year after I take a look at
one.  I plan on getting the basic 100 watt unit with the standard SSB filter
and one CW filter.  I've received a few comments on Yahoo groups about this,
but I still can't decide on the 400 or the 250Hz filter.  I like to tune
across the band with the wider filter selected and then go to the narrow
filter to make the contact.  It seems to me that the 250Hz filter would be
the way to go.  I understand that there is actually only 65Hz bandwidth
difference between these two filters.  I enjoy operating the NAQCC QRP
sprints and SKCC sprints, but otherwise, do not do much contesting.

I would also like to know if it is possible to transmit on AM using the
wider FM filter.  I haven't used either of these modes on HF in the past
several years, so I would probably not purchase one of these wider filters
at this time, but it would still be nice to know.
