EME depends on the abilities of both stations. For CW-eme on 2m this
means the sum of antenna gain of both stations should equal 40 dBi,
and the transmit station runs a minimum of 600w output. JT65
effectively increases station performance by roughly 10-dB. That
means two
Hi Jan,
What is your antenna. There has been an ongoing thread on the SteppIR site
regarding this identical problem with many types of transceivers, not just
the K3. If you have a SteppIR antenna (any model) you should take a look at
their Yahoo site.

Hello everyone!
I have a Signalink USB box that I'd like to interface with my new K3. From what
I understand the preferred connection method is via the rear Line-In/Out jacks,
right? I am using those with my rack audio gear, though (xlr mic/EQ/mixer/etc).
What would you guys suggest that I do?
Sal,
When I had a SignaLink connected to my K3, I had the Kenwood cable set for
the SignaLink. It connected as follows:
-USB from computer to SignaLink
-Cable from SignaLink to K3 rear panel Line-In and Line-Out, as
appropriately marked.
Now I just use stereo cables directly from the sound
Slava,
Yes, you should be able to use the front mic jack. Set the SignaLink
for mic level output rather than line level (see the SignaLink
documentation). Turn bias off for the front mic.
It is feasible that you could feed the SignaLink into your audio rack,
but it should not run through
The only time I have experienced some amount of attenuation on receive
is when I was using some other amplifier besides the KPA 500.
I found I had to totally disconnect all my cabling between the amplifier
and the rig. Since I am using the K line completely, trying to use an
external amp
The FX-951 features look great and I'm considering one to replace my old
Weller EC2001 with EC1201A pencil. Tips are hard to find for that model
these days.
What FX-951 tips work well for SMD parts? Mostly I solder/desolder
components with leads, but occasionally I need to solder or desolder SMD
K2 Audio Distortion.
My otherwise flawless K2 # 7359 is found to have
serious audio distortion problems on received and transmitted signals on 40

The problem appears as soon as I go above 7171 kHz. On 7182 the problem makes
SSB contacts impossible
Lower frequencies do not suffer. Why ?
Your mileage may very but I use the T18-BR02 tip for both SMD and
through hole soldering.
I'd planned on buying more tips but frankly I'm 100% satisfied with
this tip.
I should probably get a larger tip though for soldering connectors and
such.

I would keep a close eye on this. I had a bad issue with attenuation and

Hi Hans
You seem to have a known problem - with a known fix: Weird behavior around
7185 kHz. It is due to interaction between the VFO and the PLL reference
oscillator. Search for '7185' in my list
http://la3za.blogspot.no/p/la3za-unofficial-guide-to-elecraft-k2_5502.html
Hans,
That sounds like the old WAOF (Weird At One Frequency) problem. That is
the region where the PLL oscillator and VFO frequencies cross paths
near 7185 kHz. See http://www.elecraft.com/Apps/Alert11_WAOF.html.
Note that this alert refers to older version A K2s, you will not find

Nice list you have, Sverre. My K2 (#380) didn't
suffer from this malaise (I tested it as
specified) but I've done most all the others. Most
recent was the AF pot mod: No parts, but fussy
work on the three main boards -- and well worth
the effort!

Just back up your configuration with the KX3 utility before you start, and for

Thanks everyone!
Don, will this setup liven up the mic? Or is there a way to just switch to
front panel mic input only when using SL USB? I mean I know I can set the menu
option to fp mic. But if I didn't and SL USB keyed up the rig - my actual mic
would be live, right?

Slava,
That all depends on whether you feed the SL USB through your mixer or go
with the front panel mic.
Through the front panel, set the mic select to the front mic and bias
off. Use VOX and do not connect PTT from the SL USB and you will not
have any PTT 'mistakes'.
If you feed it
Well, I have never had my K3 hooked up to any amplifier other than the KPA500.
Before I got the KPA500 I did have a PW-1 but I sold that. Which reminds me, I
should buy the new brick amp for the KX3.

Bob,
I had #13 (Beta tester!)
IIRC. the only major change was the number of turns on one of the
toroids if you're into 80M
From the KXB3080 Errata notes:
Your KX1 must have an 18-turn inductor installed at L3 before using
it on 80 meters. If L3 in your KX1 has only 6 turns, see “KX1
Builder’s
Not that I know of Bob. After the initial KX1, they brought out the 30m
add-on which I have and the 30/80m add-on which I don't have [life at my
age isn't long enough for QRP with short antennas on 80m :-)]. Mine is
S/N 678 I think, it's buried in my SOTA bag and I don't have time to go
The extended temp compensation is mostly about transmit frequency stability. It
might make some difference in decoding PSK31 as the rig cools down, but I would
expect that to be a smaller effect.
