And yet people still complain about contests...
IMHO, if it weren't for contesting the bands would be real quiet.
By the way, it is not my goal to make this into a contesting yes or no
tread.
I'm doing my best to learn code so hopefully I can join the fun next year

I'm building an isolation box (between K2 and computer with external
soundcard) for digital operations, containing two 1:1 transformers and
voltage divider resistors. The box is metal. All input and output sockets
are 3.5mm mono and are grounded to the box, hence all input and output
braids are
If you do that, you can leave out the isolation transformers - and the whole
box for that matter.
You're un-isolating them by connecting the grounds together.

Did it ever occur to you that the folks who kept the bands hopping for
48 hours might enjoy a rest? Maybe spend some time with their families,
watch the Winter Olympics on TV, go for a walk, etc.?
Even though I was only a casual participant in the contest on a single band,
I enjoyed the respite.
On Sunday I worked tons of JA, and was called by VK and ZS. A hell for me
broke after I called CQ on 40m at 2300. Many stations calling on identical
frequency and with same signal strength. Diversity with Beverage did not
help as all the stations were EU.
I demand a new upgrade from Elecraft. A
I had a similar experience at W7RN when running EU. Things improved
when I turned the RF gain down, AF gain up, AFC off, audio limiter set
well below the threshold of pain. The AGC was tending to make all the
signals the same level. Turning it off helped me a bunch. For most of

As I wrote, yesterday, I have to sell the K2/100 to raise the funds I need for
another K3/100. I posted an FT-1000 on eBay, yesterday, and it sold in less
than 10 hours! I have gotten just one response on this reflector. I am anxious
to get the second K3 for my station, so I don't want to wait.
Euan,
Your grounds should not be connected between the K2 and the computer -
that will un-isolate your isolation box. At the isolation box, use
stereo plugs and jacks at your interface box and connect the
transformers to the tip and ring. Similar if you are using an
opto-isolator on the PTT
Hi all,
Well I'm reconsidering and thinking again of adding the KPA100 to my K2 (the
contest this weekend has changed my mind a bit hi hi).
My question is, do I need a regulated 13.8V PSU to do the tests and
alignment or can a 12V battery be used? I have a huge deep-cycle 12V that I
use with
LS,
The battery will do fine if it has sufficient capacity. In fact, you
can connect a small power supply to the battery to keep it charged and
operate that way forever if you want. A fully charged lead acid battery
should normally produce 13.8 volts with the charger connected.

Ok, thanks Don... It's an Optima yellow-top deep cycle battery (I believe
it's an AGM type). I've used my 706MKIIG on it at full power and it just

Didn't think about putting the small PSU on it, tho, thanks for the tip!

My instincts would agree with Bob on this question.
You might consider using stereo jacks with (Ring Tip) only wired and
use the GND as sheilding.
Or you could omit the connector and wire direct out with a rubber
grommet in the box wholes.

Hi,
Is it possible to mixed TX audio into the Line-out with a FIXED level

Currently the monitor level is the input to line-out. but some

is useless to listen. You will hear only the

When I built my interface box here (years before K3's were available - HI), I

was
at the mic connector on the radio.
My metal isolation box shares ground with the computer. That way I can
use normal audio jacks and cables. On the other side, I use a DB9
connector to isolate the box from any wires going to the radio. My PTT
connection is isolated via an optoisolator (4N33), requiring another DB9

Hi,
Yes, the K3 has an audio limiter, but more importantly it's AGC can be
configured to virtually eliminate audio level differences once the signal is
above the AGC threshold. Not everybody likes this, but it will prevent the
experience you mention with the K2.

Chuck,
The K3 does have an audio limiter whose level can be adjusted - it can
be present when the AGC is off, there is a menu item to control it.
As far as the K2, try operating with AGC on, and the strong signals will
be subdued. Due to the slope of the K2 AGC response, you can still
Hi,
For regular CW and SSB operation, the standard master oscillator is more

Try a quick test - plug the paddles into the KEY jack and close the dot
contacts on the paddles. If the K3 transmits, then the KEY jack is

You can set the radio to tune on 5 watts automatically. You can go to
the TUN PWR menu in CONFIG and rather than NOR set it to 5 watts. Then
whenever you enter the tune mode it will put out 5 watts. Then when you
are done tuning you'll still be set at whatever power you were before.
