CW RX

pastormg
Good Evening,
I have been tinkering around with the RX EQ #'s for CW. Would anyone have any good settings to recommend?

Re: CW RX

Barry K3NDM
Mark,
      Only you can determine what is correct. You need to use a CW tone
that "feels" best to you. After that, knock off all the frequencies
above and below your desired CW tone. What you are going to do is
essentially filter out more noise and distractions that your receive
filters allow through.  The problem with more specific recommendations
are that I hear audio differently than you, therefore you need to set it
up for yourself and your ears. That's part of the fun of having a radio
where you can adjust everything, finding what works best for you.

Note that Rx EQ does not add additional stages of filtering selectivity.
The DSP builds a single filter which includes the equalization parameters.

In general, you should start by setting the RxEQ on voice signals until
things are equalized for your speaker or headphones and your ears, and
adjust the selectivity  of the radio using the shift/width/hi-cut/lo-cut
controls.  And APF for certain weak-signal CW, of course!

Hi Mark,

Barry's recommendation is what I did, however, there is one other thing to consider. This topic was discussed a few years ago on the reflector and Lyle advised that it was not recommended to peak up a desired frequency on CW. Only use negative settings for undesired frequencies. The reason was that at narrow DSP width settings like 50Hz or 100Hz the RX EQ is cut off. So if you had a peak setting of 8db in the RX EQ and you narrowed the bandwidth you would hear a sudden decrease in audio volume of 8db as you turned the width knob counter clockwise.

Of course that was many firmware revisions ago so this might not still be true.

Hi Mark,

Yes, I have been using the settings recommended by Fred Cady - KE7X and think they are great:
Set 50 Hz at -16db
Set 100 Hz at -16db

Set 200 Hz at 0db

Set 400 Hz at +6db

Set 800 Hz at +6db

Set 1600 Hz at 0db
Set 2400 Hz at -16db
Set 3200 Hz at -16db

I use similar settings - except I follow the advice of Wayne and Lyle
against using any boost in the EQ.  That leaves the bottom two and
top two bands at -16 with the middle four flat.  On occasion, I have
also set the 1600 Hz band to -16 dB but I set Pitch at 490 Hz which
places 1000 - 12000 Hz well down on the filter skirts even if I have
widened the DSP to 800 Hz.

Re: CW RX

In reply to this post by pastormg
It's personal taste, your headphones/speakers, and state of your
hearing.  My hearing is pretty bad and my hearing aids don't work under
headphones [I never use speakers].

CW: Don't boost anything over 0 dB, RX EQ goes away at very narrow DSP
BW settings ... don't remember exactly where.  You can reduce ranges
above and below your pitch level to remove noise, although I've never
been very successful at that.

SSB: On advice from Jim, K9YC, I set the profile to approximate the
shape of my hearing aids [inverse of my audiogram].  You can get +/- 16
dB, but if you lower the bands where your hearing is good and raise them
where it is bad [usually the higher frequencies], you can effectively
get about a 30 dB total range.  You'll have to run the AF gain higher to
compensate for the EQ reductions of course.  30 dB isn't even close to
what my hearing aids do, but it does help a lot.

Most importantly, follow Jim's advice and GO SLOWLY!  I flailed around
changing the settings to no avail and finally gave up and left them
flat.  When I went back and tried again following his advice, I changed
one setting at a time and put operating time in between changes, keeping
track of what I was doing in my station notebook.  After awhile
[multiple days], I could tell I was improving the intelligibility of SSB
for my ears.

Dear Fred

Regarding your hearing aids you may be interested in a product that can send
LF from K3 directly to your hearing aids.
The Danish company Phonak are selling a device under the name of TVLink
which plugs into the line out, Scart, headphone or external speaker
connector and from it's console sends in stereo to your hearing aids.
I have been using this for about 4 years now and it is the best "headphones"
I have ever had! The price is about 3000 Danish kroner which is something
like 450 US $.

Re: CW RX

Hi Kjeld,

Yes, my aids are Phonak, I've tried the TVLink [belonged to someone
else] and it does work well.  I think it's BlueTooth, my two aids talk
to each other and change programs at the same time. Sadly, they do not
include a boom mic which I need.  I also need to shut out surrounding
sounds.  I really have to focus on the one signal I'm trying to hear.  
The US Veterans Affairs gives me my aids since my loss is the result of
combat service, I'm really very grateful that I get to walk around with
$6,000 of microelectronics stuffed into my ears that were free. :-)

I'm mainly a CW guy, would be my choice even if I could hear well, so
the K3 RX EQ makes SSB "possible" for me.

I was little.  Mom's mother conversed in German with me until Mom and
Dad found out, it was WW2 and they didn't think that was all that good :-)]
