Morning all
A long shot:- does any UK user want to sell me a used roofing CW filter for
the K3 ? Prefer 500Hz but open to suggestions.
Thanks

If it is true that all modern chargers and laptop supplies are switchmode
(?), I can't immediately see why they shouldn't run from a suitable dc
supply, since the first thing that happens in a switcher is to rectify the
mains. Even my 5 year old stuff is universal input, ie very wide voltage
Thanks Wayne. All the settings look good. With the balance knob fully
clockwise, the sub is in the right ear. Turning CCW, the main starts to be
heard at 3:30.

On the K3 and KX3, is it possible to set/get the sub-mode of PSK D (45 or 75
baud.)?
Is it likely in the future that the K3 and KX3 will support a 63 baud
variant of PSK D?

Has anyone with a KX3 successfully interfaced the HDSDR program to be able to
use it for control and spectrum display? Not having much luck here. My laptop
does have a very good integrated stereo soundcard with selectable stereo
line-in or mono microphone and an available 96K sample rate.
Jim,
I was able to make it work. I have an E-MU-0202 card capable of
192KHz, but I only use 48KHz as I like the definition better.
I was unaware of any internal laptop sound cards that will run at
greater than 48 KHz. If your sound card input is stereo, I suggest you
try 48KHz and

I totally agree with Jim. Hard to beat the Sony MDR7506 headphones.

I prefer the Sony MDR-V6. Same as the 7506 but a little less bright
sounding.

You should consider the JRC ST-3 headphones. I have used mine for about 15

I'm a cw only op also.
Over the years I've had custom made inner ear plugs, a Meyer Aviation

Hi,
I have absolutely no dip in the center of my LP-Pan display and I have never
heard anybody else having this problem either. The IF out port and the
crystal filter bank are driven in parallel by a buffer amplifier that
appears to be capable of driving both without gain loss due to the crystal
If one looks at the schematic there is a JFET buffer between the IF and
the IF out in the main RX. Isolation and impedance matching is its
function. There is no stock IF out for the subrx and hence no JFET.
JFETs have really high input impedances.
A one resistor gain mod is on the K3 site
I'm amazed at what a high proportion of my contacts recently have been ops
with KX3s. I'm sure a lot of it has to do with it being relatively new, so
will get preferential use from hams who have plenty of options, but it
still surprises me. I'm only doing CW and hanging about the QRP watering
This is a question for the group and not Elecraft staff.not that I don't
value their input but I want to be a good ham op and not do what I am told not

order. I know the folks at Elecraft are shipping these items
Hi All,
Last Saturday I got a notice from Elecraft that my KAT500 was in the loop,
and for me to confirm my order, which I did post haste. Monday morning I
got an auto shipping notice. I thought, Boy, that's fast! The tracking
info said it would be here today. Well, a package did arrive,
I don't have an L-P Pan.

Hi Group,
I've just finished building and calibrating a KAT100 to go with my K2
/ KPA100 combination. The build was very smooth and the calibration
routine straight forward. It's tuning my 80m loop, multi-band, just
fine.
I'd like to check my understanding about
John,
If the KAT100 is used with the basic K2 (no KPA100), then the KAT100
will provide the forward and reverse power indication and those values
will be displayed by the K2 during a TUNE.
When the KPA100 is connected those forward and reflected values come
from the KPA100. A similar

Last night I changed over from a true RS232 CAT interface to a USB to

Ariel.
While it is sometimes possible to clip the leads on the top of the board
and use the remaining leads to mount new diodes, I suggest that is
cheating. I always remove the board from the heatsink and de-solder
the diodes from below.
Usually, the thermal pads will stay in place and can be
If you can clip the bad diodes off at the glass enclosures, you may be able
to simply lay the new ones in place and solder their leads to the stubs
sticking up out of the pcb, then trim the excess off. I can tell you from
years of experience that a lot of field repairs are made that way on
Wayne has assured me that torn pads are no problem as long as pieces are not
pulled off and lost, and I have been through that many times with no
deleterious effects on my KPA100!
