I recently purchased a K3 and trying to set up for SSB.I do not do code.
Is there any recommended settings for the shift lo cut and width?
It has the KFL3A-400 and the KFL3A-12.8 8 pole filters installed
I have read the manual and it does not really help me.
Thanks
Bill

Re: Filters

Bill,
For SSB use LoCut and HiCut, not shift and width.  Shift and Width will
drive you crazy because each time you reduce the width, you will have to
adjust Shift to maintain a good center frequency.  HiCut.LoCut adjusts
it automatically.

Set the low end between 300 and 400 Hz initially, then set the high end
initially for 2800 to 2900.  If there is QRM on the high frequency side,
reduce the HiCut, and if there is QRM on the low frequency side,
increase LoCut.

You will find that you cannot cut the low frequency end very far before
you lose intelligibility, but you can cut the high end significantly.
While you will lose the voice characteristics, it will remain
intelligible down to 1600 or 1800 Hz.

Congratulations. The K3 is a really nice radio with
extraordinary factory support.

For SSB, I set low cut to .35 KHz and adjust the upper cut
between 1.9 KHz and 2.8 KHz, depending on conditions. Higher
makes for easier copy, but lower will eliminate more noise, and
help with nearby stations. Remember, the crystal filters are to
protect the AtoD converter in the receiver. The DSP has many
useful settings between those of the installed filters.

Hi Bill,

Adjust the lo and hi cut filters to make the signal you are listening to sound good (in the absence or QRM).  In a crowded band with QRM on either side, adjust either the lo or hi cut to reduce or eliminate the interference.  Note that the lo and hi refer to audio frequencies.  If an interfering station has a higher pitch, adjust the hi cut; lower pitch the lo cut.  You shouldn't consider these controls to be set and forget.  They can be changed to meet changing reception conditions.

Lo and hi cut have no effect on your transmitted signal.


Cheers and enjoy the K3.

Re: Filters

Hi Bill,

For SSB use the LoCut/HiCut mode. Set LoCut for 300Hz and HighCut for 2700Hz
initially.  That gives you comfortable audio when there is no serious QRM.
If QRM from above in frequency bothers you, crank the HiCut down to 2400Hz
or even 2100Hz. If you have narrower crystal filters, like 2100Hz or 1800Hz
they will switch in automatically. Don't touch the FL button. If you have
QRM from below (assuming USB) unfortunately there isn't much you can do. As
Don says (in a different thread), cutting the lows much above 300Hz quickly
affects intelligibility. Lowering the HiCut also lowers the noise floor of
the receiver if you are listening to a signal in the noise.

Believe it or not, in some SSB contests I've dropped the hicut down to
as low as 1100/1200 Hz and still been able to copy some voices. It's
really dependent on the voice characteristics of the operator on the
other end, but it works often enough to be usable in heavy QRM.

Good info on the filters I had never tried the LO/HI CUT and I like it. One question: On my K3S I cannot set the LO CUT to .35KHz it only steps in .10 increments not 0.05 increments is there some CONFIG item I need to change? I looked through the CONFIG menus and Fred Cady’s book however I did not see anything about setting that step.

Re: Filters

Bill Frantz
Mine moves in .10 increments, but it seems to like the numbers
that end in 5. e.g. .350. I wouldn't worry too much about it.
set the low end to .3 or to .4, depending on conditions and the
voice you're listening to and call it good. The whole purpose of
the knobs is to let you adjust the bandwidth to match conditions.

Re: Filters

In reply to this post by Elecraft mailing list
Yup, you are right. The manual clearly states that PB CTRL only affects CW and Data modes, and shifts the increment between 0.05 and .01 KHz.
It appears to be fixed at .1 KHz for SSB for both low and hi cut. Those increments work pretty well as is.

Temporarily switch to Shift/Width and set Shift to a value that,
when divided by two results in a value of X.X5.  Now switch back
to Hi/Lo ... those value will end in X.X5 and step in increments
of X.10.

Re: Filters

Hi,

You don't have to do any math to do this. Just go to shift/width and change
the width one click (either direction.). Then switch back to HiCut/LoCut. To
reverse the process, do the same thing again.

Re: Filters

On SSB a change of 50Hz bandwidth is usually insignificant.
Those who are blessed with perfect pitch may differ when listening to a
single tone, but for communications effectiveness, I just don't see the
point.

Just as another observation...  My Low Cut on SSB in Norm I is set to
0.015 by default.  I can dial it UP by 0.1, 0.25, 0.35, etc.
OR, if I dial it down to 0.05 as long as the starting point is above
0.05.   Cannot dial in 0.05 from 0.00.

I don't have "perfect pitch", but do have extensive music experience if
that matters....

Single tone, single voice, or an orchestra....  50Hz off freq. is enough
to make me want to drill holes in my head.  I can easily distinguish
below 10 hz, and sometimes 5 Hz.... and my ears are damaged from years
of rotary-wing flight/maintenance, small (and larger) arms reports.

That said...when using Lo/High/Shift/Width, the 50Hz resolution is being
used in a "relief from distractor" mode, so it is less of an issue, but
there HAVE been times that I wished for a slightly finer resolution.

Re: Filters

Don Wilhelm
Clay,

We are not talking about shifting the pitch of the signal by 50 Hz, we
are talking about enlarging or restricting the pitch at only the low
frequency end or the high frequency end by 50 Hz.
The LowCut and HiCut controls are like the Bass and Treble controls on a
car AM/FM radio.  Think what would happen if your radio's Bass control
were reduced by 100 Hz instead of 50 Hz - the difference is insignificant.

Oh yes, the Bass and treble controls on that  AM/FM radio are not
calibrated for precise frequencies like the K3 HiCut/LoCut controls are,
so we "use our ears" to determine what is best.  We should do the same
for the K3/K3S/KX3/KX2.

There is no communications effectiveness for frequencies below 300 or
400 Hz (0.30 to 0.40) on the low cut side, and there is little voice
recognition in that range.  The effective range for voice recognition
begins at about 500 Hz, and extends to about 2600 Hz.  That is for
recognizing the characteristics of a particular voice pattern we are
familiar with.  For communications effectiveness, we can reduce the
listening range to 500 Hz to 1700 Hz and still communicate with clarity.

73,
Don W3FPR

Re: Filters

W2xj
For most speech formants there is a gap above about 1000 hertz. If one is depending on only the F1 formant, then a cutoff of about 1000 hertz is appropriate. Another rule that applies is the 450,000 (or 500,000) rule. Multiply the highest frequency by the lowest frequency and the product should be one of those two numbers for a balanced response. So, if the upper cutoff is 1 KHz, then the lowest would be 500 hertz. Such a response is slicing the F1 formant which is typically 1 KHz wide.
