I am new to the list, and did not find this in the archives or other materials.
If this has been discussed or otherwise, a pointer to the data would be great.
When selecting filters for various operational modes on the K3, I was wondering
if the 6k filter is ‘Required’ for ESSB operation, or if

Greetings, Just got my new K3 options in Monday and
had them all installed by Tuesday morning. I installed
3 of the 4 possible optional roofing filters. They have
been turned on and the BW set in config. My problem
is when I power down the radio they cannot be called
up by tapping the XFIL button.
Hi Wes,
This is by design. Selecting a filter manually via XFIL normalizes the
DSP bandwidth to the crystal filter bandwidth. Using any other method
(WIDTH, SHIFT, LO, HI) selects a crystal filter based on the DSP
bandwidth (which you can see by rotating WIDTH, or just tapping it
twice).
I received my new 400 Hz filter midway through the WAE RTTY contest and since I
wasn't really contesting, took the time to install it.
I guess I'm a little underwhelmed so far, but to be fair I wanted to compare it
under fire with the 2.8 KHz filter I have been using. (I expected less buckshot

Keep in mind that the "working" selectivity for shaving off QRM is provided
by the adjustable DSP filter in the 2nd I.F.
The crystal filters in the K3 are actually "pre-filters" whose primary
function is to avoid overload from extremely strong signals.

I have the 400/200 and have been happy with it for CW and digital modes,
though I added the 1KHz for CW tuning and wide digital modes (not RTTY).

I've been using 2.8 KHz and 400 Hz 8 pole filters for about 6 months and
find they work just fine. I've not found a need for a narrower filter.
The dynamic range of the K3 is good enough to not worry too much about
needing a roofing filter for every occasion. I run CW, SSB and data
modes

I keep seeing talk of the 400(435) or 500 combined with the 250(370). I see
very little talk about the 200. My thought was to use the 400 and the 200.
Maybe the decision should include the 500/200 combination. Is the 200 just
"too narrow" or why don't I see more apparent use of it? I know, what
I have the 1.8 and like it - it's not hard to get SSB down to that and
still hear clearly if you adjust it properly.
I always start at 2.8KHz and then bring in the filter. On LSB, start
by adjusting the Hi cut until you've almost got to 1.8KHZ, then adjust
the Lo cut and maybe the high cut ag
Chris,
Many people like the 1.8. I have the 2.1 Inrad combo in my ol' MP.
Pretty narrow to my ears. And I can use the shift width controls to
decrease the bandwidth some more.
I ordered the 2.1 for my K3.
If I need to knock out something, I'm convinced that the DSP filtering
will make it so. Othe

Hi,
Looking to get 8 pole K3 filter for SSB contest work, to knock out close in
stations, considering the 1.8MHz filter, maybe too narrow?
Suggestions based on experience much appreciated.

Fully agree with 2,7kHz and 500Hz 5 pole filters being sufficient.
Add there 6 kHz for AM and (15 kHz) FM, if needed.
And of course the coming variable filters are interesting, or at lest
one of them.
I think 5 was a good estimate, after all.
But this is not the end of it.
Take a KRX3 Subrecei
If you plan to use CW or narrow data modes -- even a little -- you'll
want at least one narrow filter (our 500-Hz 5-pole filter is a very
cost-effective choice). I'm not trying to sell filters, but I want K3
owners to get the most out of the K3's receiver architecture. It's
