My KX3 is often operated remotely via a Raspberry Pi and VNC - mainly for
digital working with JS8Call and WSJT-X.
I’ve set up a set of programmed instructions that I run before each session to
make sure that everything is set up correctly such as Data Mode A, Power
Output, Microphone and Audio
Hi John,
Would you elaborate as to why you want to have 500-2500hz as your audio
passband width? I have my KX3 BW = 4.00 and run split mode with JS8Call
and WSJT-X. That keeps my signal in the sweet spot and gives me a view to
other signals up past 2500Hz in case I want to try to work them.

When the next KX3 software update is planned, will you please consider the
following items:
1) The VFO B knob is in the B position at start up. When tapping RIT ( or XIT)
the VFO B knob switch to OFS, as it should. However the VFO B knob remains in
the OFS position when tapping RIT again to swi
Bottom end of the audio passband at 500 because all heartbeats etc. should
normally be in 500-1000Hz range. As to bandwidth, I am in a very noisy City
environment in London. My antenna is a 12m end fed wire tied to the top of a
wooden fence - and half of that length is shielded as it is betwe
Rear panel mic input, electret mic. Mic+Lin on. VOM shows 8V across mic
element. Tried several mics.
VOX works on CW, not on SSB. What am I missing? It used to work.
No biggie, I'm a CW guy but FD is coming up.

Ahh indeed. Several hours at W7RN with a new router trying random
things was less than productive. A more structured, several step effort
at home yielded the solution, which was primarily router pilot error.

I hooked up a new bug (begali intrepid) and am noticing popping when keying
dahs - I if I add a 4.7uF bypass across the key line it clears this up but
it’ll sometimes make it so there’s no dits. I can’t figure this one out -
is there something I need to do to make sure there’s no extra garbage when
Nice!! A Begali Intrepid,
All bugs will have contact bounce. K3 does not handle them well at all,
same for KX3/2. K2 is much more tolerant. Though normally for the dot side.
I fixed it with a home-brew debouncer:
https://www.kn5l.net/debounce555/
Others cam be found on the WWW. It was fun design
TJ,
No callsign?
What rig are you using?
Are you hearing the popping sound in the sidetone?
Definitely don't put a cap across the contacts.
You may need to diddle with your QSK settings.
Other users may be able to help you more if they know which rig.

TJ, your six miles line of sight, what to come by and borrow it for a
while to see if it's a fix?

Thank you for the additional details. The commands you wrote about in this
thread should give you what you want. Have you had a chance to try them
out yet to confirm? I haven't tried myself, just read the programmer's ref
guide (E19) and drew it out on a piece of paper so I could see the
bandwid
I have tried all kinds of debouncing circuits, but the one that has
always worked best is simply a 12v reed relay with a 10uf capacitor
across its coil -- not across the contacts!
I used an SPST reed relay I got at the now-defunct Radio Shack, but
there are many such relays that are suitable.
So bias is obviously turned on. I'm guessing VOX Gain, Mic Gain.
Try putting the K3 into TX mode with the front panel button, talk, and
set mic gain to get RF out, then stop TX and set VOX Gain (short push of
Menu).
For max talk power, set TXEQ with the first three bands max cut, about 6
dB
Another thought, Dick.
We need to set Line In gain and Mic Gain separately. To do that, we must
be set for Line In to set Line In gain. Check the manual -- I don't
recall if the knob is adjusting Mic Gain in the Mic + Line position or
if we must change to Mic In to set it.

Components fail for a reason, which almost always is because they have been
over-stressed. Component manufacturers spend a lot of time analyzing their
devices to determine their stress points, failure modes and safe usage areas.
When we design equipment, we look at this information to make sure
I agree the root cause needs to be identified but my point is in standby power

also until the failure.
Once something failed the amp is now reporting incorrectly that there is

Don,
Finally got back to the K2 this afternoon. I have confirmed that T5 is on
the yellow core, with 16 turns through the center on the red and 4 turns on
the green. I mentioned earlier that I got all the toroids from the Toroid
Guy, so I felt confident that it was correctly wound. I checked all t
Sounds like you might have inadvertently changed the antenna selection — e.g.,
ANT 2 when your antenna is on ANT 1.

Hi all, I'm new to the list. Just turned on my K3 and noticed I have no power
out on 20 meters. I have performed all the normal trouble shooting stuff. The
transmitter is fine on all other bands and has normal 100w output on a Bird 43
and Bird dummy load. It makes no difference if the rig is in
Hi Folks,
I am having an issue with the band data out from the K3s and K3S. Both
have are basically new. The K3S was NEW in Aug 2018 and the K3s had the
I/O board replaced at the same time. Both units have the same issue.
They don't seem to be able to drive band data input of a couple of

What are the values of the pulp resistors on the decoders, and what voltage do
they pull up to? If 12V, the yes, you really need to worry about the 2.2K
resistors and that 1K series.
Even at 5V you may have to do so. Work the problem out on paper - simple ohms
law. Then determine if the low volt
Good Evening,
Both bands had a medium level of QSB; but copy was OK on each of
them. Mostly tales of yard work but Dave was doing antenna work. He
had a much better signal than he did last week. I had frost last night
while Roy had some snow. I remember skiing in Wisconsin on May 5th so
I've found my DVR handy for calling into large DX pileups. It saves my voice.
