Hello,
Yesterday, I was re-reading the KX3-manual to prepare for putting into use a
magnetic-loop-antenna.
The KX3 manual, on page 14, has this wording "TUNE is used to put out a CW
signal at the power level selected by the PWR control.".
This is new territory for me as I have never have used
If your antenna is a magloop - DO NOT USE the tune button. In fact, clear
the tuner memory for your band per instructions. The tuner feature
(assuming you have the option) is great with other antennas, especially
random wire but it doesn't go well with mag loops. The xmit button is
simply
Even in Europe (east of the Rockies somewhat...). Got still 2 spares in
the box for my three K3's. There's a reason.

Hi Jerry,
The CW signal from TUNE (or ATU TUNE) is *truly* continuous, not pulsed on
and off to spell things in Morse. It's like holding down a straight key,
except it's a toggle so you still have both hands free. As Lee noted, you
can ID before or after tuning, or just roll it into your next
While this may be an old thread, I have an input which could be interesting
to some. I recently noticed the KAT500 I am currently using had V1.75 of
the firmware installed. I use it with an IC-7610 and trained it on each HF
band, placed the MODE switch in MAN and tuned it for the FT8
Hello Elecraft users,
Lightning struck the SW tower here on Sunday afternoon. Among many other
things, it blew out the KIO3 RS-232 serial interface on one of my K3's in the
process.Does anyone have one available?

2) it's just a carrier
You can ID either before or after the Tune process.

Ah, lightning. Whoever performs an analysis of the KIO3 failure mode after
being struck by lightning might have what's necessary for a very lucrative
business.
Actually, I'm surprised that the board hasn't already been reverse engineered
in China, enabling an aftermarket for KIO3 replacements.
Jerry: Just in case you are not [yet] aware ... Small so-called
"magnetic loops" must be exactly resonant meaning that you go to TUNE
mode [i.e. feeding power to the loop] and then adjust the loop for exact
resonance. While exact resonance is indicated by zero reactance looking
into the
Yes, for sure. That little board seems to have by far the poorest
reliability history of anything in the K3.

Not owning a K3, but have the KX3..and other rigs! Perhaps
disconnecting the antenna (before and during an electrical storm) from the
shack hardware makes little boards like the K103 enjoy a longer life. Just
suggesting. No disrespect in this comment.

When my KIO3 got zapped, I had everything disconnected. Antenna and all
accessories from the K3 ... power supply as well. The one thing I
didn't have disconnected was the RS-232 link between the laptop and the
KIO3. Somehow a transient from a nearby lightning strike (not a direct
one to
I will look tonight and see if I have one?

Yep, series mode protectors. Got a few of them. But when tstms threaten,
*everything* gets disconnected from the K3/K4, including headphones, key
and speakers.

I can think of two reasons. First, cable shields are not bonded to the
chassis at the point of entry; instead, they are capacity-coupled, and I

Hi Thomas,
I didn't solve it yet, but I haven't given up. I'm in Finland working at the
moment, but will be home tomorrow - I'll find and forward the email I had from
Elecraft giving some pointers about where to look.
Best regards,
