Exactly, I have noticed this too but never said anything before.
It did happen a few times during the SAC CW contest that I operated,
never had time to take part in CQWW CW. The radio do have
a problem in this respect and I can see that 5B4AGN has found
it too.
Something is going on but what it is
I finally got to use the APF in reel life, I´m not too
active these days.
Wanted to work the ZL8X boys on 160 so went out to the
radio station and brought the K3 with me and fired the
big rig up.
All I can say is that the APF is excellent. ZL8X was weak
as water but with APF it was possible to copy
For a CW signal with clicks at the break side (like the majority)
the faster you key the stronger and wider will the click bandwith
be. This can clearly be heard every day on the ham bands.
So this calls for Camp 2.
However I do not agree that it´s either 1 or 2, in practice it works
differently.
Fourier analysis on this but it
was 35 years ago and I just have forgot it all. The teacher I had
was a ham but he is an SK now.

No I do not experience key clicks with my own K3. I don´t know
what it sounds like and it´s no idea to ask anyone either.
It is all the other K3´s that are on the air that has "mild keyclicks"
Yes there are hot switching amps and QSK amps that aren´t
correct, I usually can detect those.
No it´s
Yes I do know that it´s not the rise/fall time
alone, that has never been my point. However
one factor is the rise/fall and if it´s too fast
it will not be possible to fix it with shaping.
Why, yes IMO the K3 clicks too much. I know it
can be done since there are radios around that
doesn´t click a

OK. AFAIK at 4 ms a CW TX will have to much
bandwith. Even the K3 at 5 ms (if it hasen´t changed
since I measured it) do have "mild clicks". I wish
the K3 could be set to something like 7 or 8 ms.

Yes APF came out reel good, very well done! Don´t even know if

Now if only AM RX was to be fixed I would be happy, as it is

Gone here too. But we have the FM BC band around 100 MHz so they could

If I would set mic gain to 22 with my HC5 I would overmodulate.
In my case gain 12 and comp 25 is just fine, however it might
differ with how one sets the TX EQ. With this setting I get

Interesting, good info. Been on this list for 3 years or more
and ha
I have measured myself however didn´t come up
with as poor and/or as good numbers.
What could be interesting is with what and how
did you measure.

Doesn´t seem to be a fix. My K3 is just about the same.

Yes I suppose that´s what it is. Well it´s been like that
from day one, think I have SNR 1594 so it´s been a while.
I always been upset about it since IMO a high performance
radio shouldn´t behave like this. However I just haven´t
had time to look in to it further. Maybe it´s faulty after
all.

No I have the RX EQ flat at 0, will test when I
get back home.

When tuning for example across an AM band (like 49m band)
it does not happen on all stations. Might be that it
happens on some certain frequency interval but still
quite frequent.
I have not done experiments with different tuning steps,
maybe I should. Will try it when I get back home next
weekend
When tuning across an AM station there are
clicks and cracks, seems to be on even kHz.
On my radio it has been from day one. Is
this normal or is my radio faulty?
I use latest FW.

Would be interesting!
Beats me why Elecraft can´t present the facts, I´m sure
they have measured since I bet they know how to.

That will come out to 160W PEP on the K3 and 1600W PEP
on the amp. I would not set the K3 to more then 25W
(i e 100W PEP). Don´t know how much the AL80B can handle
but 1600W PEP sounds to be too much.

Yes I will use a K3, will be on for a few hours now
and then, look for me I will look for you.

Yes but those sources doesn´t speak.

I would like to use the 2.1 kHz filter for SSB TX.
Elecraft any solution?

How about the TX side. AFAI understand it should do
"things" to TX audio.

Indeed!, Doug got this right.
In a previous msg I did say why not but thinking more
about it, after reading this, I will agree that it´s not
needed.
Too many darn functions to fiddle with anyway, enough
is enough.
As I stated in a previous message, fix the flaws and
get done with it, the K3 is a
Well I never found the FT1000D peak filter that great, decent yes,
all subjective of cource.
I remember when I had a Drake 2B with 2BQ Q-mult, that was nice,
you sure could peak signals up out of nowhere.
But sure a peak filter could be nice to try.

This is what I like to see:
1. Pritty much no more features just refine and work
on what´s already there, refine the design.
2. Better S-meter resolution, 5 dB not good enough.
3. Possibility to adjust CW keyed envelope rise and
fall time. Think it´s 5 ms now so lets say 5 - 8 ms

There sure are a lot of workarounds with the K3, the

Even with a 6/6/6 stack on 10 and a RX with MDS
of 135 dB (I think it is) you will benefit with
a low NF preamp.
However, antenna gain is NOT everything on 10m,
we are getting close to VHF and I rather would
be interested in antenna noise temperature but
maybe you just will tell us that your anten
