Pete,
I would suspect that the local ham didn’t account for you overdriving his
receiver (or test set) which would explain why an underdriven signal appeared
cleaner (no overload). Had he attenuated your 4 bar signal, it would have been
clean, I’m 100% certain.

Sorry, but I would want to see live spectrum displays of my own rig with
a known hardware setup instead of images of some other K3 with unknown
K3 settings and unknown test setup. Hundreds of us have been following
the just barely flickering 5 bar rule with excellent performance.
You know
I recommend finding someone with a P3 or other spectrum display and trying this
on *your* K3 rather than looking at pictures of “a K3”. Running with
insufficient audio drive, which is what you are doing, has known problems,
which you are experiencing.
I would be glad to do it with my KX3 and
OK guys - rather than reply individually, let me try to pull everything
together in one message.
In a previous effort at FT8 I followed the standard advice to set the
power slider in WSJT-X (on the lower RIGHT side) so that my K-3 showed 4
bars on the ALC meter, just below the threshold for
Hi Darrell,
You may want to shop around for an SP3. Same speaker on the inside.

Hi All,
Bought a nearly new K4D a few months back without a speaker, now Elecraft has
them backordered.
Anyone have a spare, or one they would be willing to sell>?

Thanks and 73,

Hi Jim,
Maybe you’d feel better knowing that with WSJT-X at max; I had always adjusted
the OS driver level plus the rig levels, starting mid range on both. And from
midway, find the right blend to get the level to be proper with neither control
at (or near) max so nobody shouts and no one

Hi Rick,
This is the only part of your excellent advice that I disagree with. The
reason is that the analog stages of computer gear tend to be poor, and
start generating increased

Yes, it hunts for a couple seconds first time on a change (freq, mode,
power, turn on). Elecraft mentioned it has to do with it setting its power
level (it works a bit to get stabilized and not noticed normally). After
the first TX time it will be fine.

Whomever K3 user told you to EVER use the output control other than MAX at ALL
TIMES needs to go back to learning. They are NOT helping you.
The WSJT-X output control is an AUDIO control, not an RF output control.
On any rig made since 1985, one wants to adjust the RF for RF and the audio for
Pete,
Set the audio level to make the first 4 bars of the ALC meter solid with
the 5th bar just flickering.
The K3 ALC onset is at the 5th bar, the bars below it are an aid to
adjusting the audio properly for digital modes.
Your advice from "other K3 users" is not correct. ALC starts at the
Pete:
The first 4 bars on the K3 ALC are just an audio level indication [i.e.
VU meter]. ALC action starts at the 5th bar, which you want to be just
flickering. Unless you have 4 solid bars, the K3 will keep trying to
adjust the TX gain to achieve the selected output power and it may not
By “first flickers of ALC” do you mean one bar flickering? If so, that will
cause power hunting.
Not sure who advised against setting it at the 4th bar, but that was probably
bad advice. That sounds like advice for non-Elecraft transmitters. I recommend
following the setup instructions on
Hi Peter,
Setting the ALC for FT8 is different than other transceivers due to the way the
K3 adjusts power.
You should adjust the slider to give four solid bars and the fifth flickering.
You find the outputvwull be ver stable then.
See you on the bands!

I have been told that the gain of the KPA500 has increased over the years it

difference in gain has been attributed to difference in the
