Unfortunately, SOME of us have had our bonding/grounding plans pushed 
well down in the priority for 2+ years now  Air gap is my only 
choice right now.,

Although I subscribe to QEX, I haven't seen that piece. HOWEVER -- I 
strongly concur with W8JI that the best strategy is proper BONDING, 
not disconnection.


Study N0AX's ARRL book on the topic, to which I contributed, and this 
slide deck for talks I've done at west coast conventions and to 
several clubs.

Re: [Elecraft] [K3] KIO3 failure mode

[Clay Autery]

Yup  Glad my hutch/desk are on ball bearing transfers Because I 
remove EVERY cable/wire too.  A year ago March I lost over 20k in 
electronics, et al from a lightning strike on a TREE 20 feet from the 
UN-GROUNDED pedestal.  I'm STILL fighting them to recover.  And with a 
FULLY stuffed K3s/P3 and NO SPARES, I keep a close eye on it.

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 my tower) traveled through the laptop power brick and to an
otherwise completely floating K3.? If I remember correctly, the laptop
power supply was even plugged into a quality surge protected UPS.

It takes very little to zap the KIO3.? I now disconnect EVERYTHING in
the shack during lightning season.

[Elecraft] Sale....Elecraft "KX3 Kit"With Tuner and Roofing Filter.

[KJ]

Hello all,
Have the following for sale..
KX3 Kit, S/N 7662. From about 2015.

Includes:
KXFL3- Dual Passband Roofing Filter Kit.
KXAT3- 20W Auto Antenna Tuner Kit.
KXUSB cable.
A grounded anti static mat and wrist strap should be used to assemble this!

Was intended as a backup for an existing/assembled KX3 but never used. Box was 
only opened to take pictures; which I will send on request.
Elecraft price for all is $1,809.85 but, as we know, the KX3 itself is on back 
order.

Note: I don't know if things have changed with the new kits but back then 
people were driving the screws in to hard while attaching the battery case and 
shorting out the main board! Nylon screws would be safer.

I'll pass over my phone number, via email, for any detailed discussions if 
requested.

$1,475.00 which includes shipping to CONUS only.
Shipping prices have gone thru the roof!
Postal Money, Bank Cashiers or as a very last resortPayPal! Can discuss 
PayPal. 
The "QRZ.COM" e-mail address is available for communication.
As usual, no returns or refunds!
Thank you for reading! Please be safe! Ken. W2GIW

[Elecraft] K4 split audio

[Douglas Speer]

Just got my K4 back from Elecraft after having the tip of my Paddle plug 
breaking off inside the socket. So I’ll just now learning the rig.  

Question on audio adjustments while operating split. Is there a menu I have not 
found that will allow adjusting audio gain separately for the main and sub 
receivers?  When DXing, I find with both set at the same level that the loud 
pileups is overwhelming while trying to simultaneously listen for a weak DX 
station.

Re: [Elecraft] KX2 Internal Battery Charger

[Wayne Burdick]

A small field-test run is being built as we speak. Over the past several months 
I collected names of volunteer field testers (you know who you are :) 

After we complete FT, which we're doing carefully because of the nature of 
Li-ion batteries, we'll open the product up for general sales. There will be an 
announcement. Or two.

Last I heard from the source about a month or two ago was that prototypes
had been built and testing was underway.  Or something to that end.

I was curious if there was any update on the development status of the KX2

Thanks!

Re: [Elecraft] KIO3 failure mode

[Geert Jan de Groot]

Many faults occur via the station ground system.? This fault indicated a
difference in potential between the station ground and the AC Mains
ground.? In many cases, the station equipment is connected between
station ground and the AC Mains ground.?? 


I think we're seeing monthly reports of KIO3 ports being blown up by 
having it connected to a PC and creating a ground loop. I wonder why 
this keeps happening over and over.


The proper solution is to have an entry panel through which EVERYTHING 
is grounded and connected together. There have been a fair number of 
publications on this over the years.


I do wonder though, if a full galvanic isolator would also help? It 
won't replace the ground panel, but having heard the stories (followed 
by "I need the KIO3 repaired and can't get parts / Elecraft repair is 
backed up") I wonder about this measure.


How such an isolator box is powered would be another matter though. But 
I wonder who tried this?

Re: [Elecraft] KX3 frequency reporting (was: KX3 and its "TUNE" selection. (With mag loop)

[Geert Jan de Groot]

>> I wonder how hard it would be to have a transceiver tell
>> the magloop what frequency it's tuned to?


That's absolutely possible over the serial port (ACC1)! The Programmer's
Reference has the details:


You don't need to go as far as sending commands to query the KX3 (or 
KX2, or K3, for that matter).
Set MENU:AUTO INF from NOR to ANT CTRL, and every time you change the 
frequency dial, change bad, the KX3 will automatically report frequency 
and a number of other parameters. Don't need to send commands, reporting 
automatically happens. Format of the status report is in the document 
quoted.


Suggest your mag loop supports 38400 baud. With KX3, other speeds do 
work but as soon as you add other things (PX3, KXPA100) you will find 
that some of them enforce 38400 baud so you "might as well".


MENU:AUTO INF set to ANT CTRL also works on KX2 and even on K3 (it's 
called MENU:AUTOINF and needs to be set to AUTO 1 on K3 but then works 
like the rest).
Personally, I use it to control my Hardrock 500 amplifier and this "just 
works".
