Larry,
I would suggest setting the lowest three bands of the TX EQ to lower
settings to reduce the bass response from the SSB RF.
Those low frequencies take a lot of RF energy, but do not add to
intelligibility. In other words, they aid in recognition of the voice,,
but do not add any "punch".
Of course you have to use compression to get any kind of decent punch in your
output. But I thought this would be obvious to anybody doing contesting.

Take a look at the Heil website. All (most) Heil mics/headsets work best
with a lot of gain and compression, at least more than you would probably
use with stock mics. My compression is 25 and gain is 50. I receive many
comments regarding the quality of the audio. Good Comments (LOL)
Good Luck
Take a look at MAIN menu option MIC SELbelieve you need to select HI mic
gain range by tapping "1" to toggle between LO and HI mic gain.

to get good audio out with good RF output.give it a try.

Having the 1.8 kHz in my K3S, I know what and how it works.
I work 2 SSB traffic LSB nets which both have LSB nets which are 2 kHZ above
my net frequency. That means at least 700 Hz to 1000 Hz of their primary
signal is in my receiver passband. The 1.8 kHz filter, the DSP at 1.8 kHz and
us
I typically use Hi Cut the most, Lo Cut once in a while and almost never
use Width in SSB mode. For me the 2.1 kHz filter works swell in this
application.
In the late '90s I bought a TS-850s which was fitted with a 1.8 kHz
factory accessory filter. I couldn't get rid of it fast enough and
outfit
Remember, different brands of 2.1 or 1.8 filters are not necessarily equal.
One must realize the shape factor is more important than the published BW.
Just because one radio filter is 1.8 kHz does not mean another 1.8 kHz BW is
the same.

Hopefully that we will remember that the DSP filter skirts are steeper
than the crystal filter skirts, so judicious use of the HiCut and LoCut
will provide us with a better passband than narrow roofing filters.
What the roofing filters will do is keep the receiver from reducing the

No, the roofing filters aren't superfluous even with lower level
signals. If you set the bandwidths similarly as I do all of the time,
the rejection of the filter adds to the rejection from the DSP. I think
this should be pretty obvious.

I concur. I have 2.8, 2.1 and 1.8 KHz 8 pole roofing filters in my
K3S. I made over 8500 SSB QSOs last month and I used the 2.1 KHz
roofing filter for all of them.

Until you get down to the noise floor isn't it always the sum (in dB) of the
rejection?

Isn't that what I said? Perhaps I said it badly.

You said: "In addition, when the DSP IF filters are set to about the same width
as the roofing filters, the two filters "cascade" -- the rejection of adjacent
signals is the sum of the rejection of the two filters. "
There is no requirement that the widths be about the same. They could be widel
Mike,
I guess you will just have to listen to one to make up your mind. I
have had unsolicited comments from shack visitors who say it really
sounds great - much better than their YKI transceivers.
Now, I do not know whether it is my audio setup or not. I use two small
wide-range external s
I would take a listen to a K3 on ssb mode and compare it to others
before deciding.
A flat RX equaliser setting sounds terrible with aggressive white noise
on my K3, using good quality headphones and/or ext speakers.
The pink noise roll off setting for RX equaliser as per ;

I would generally agree with that. The RX in the K3 is excellent, the
IF filters are excellent, the audio chain is quite
