K2 #5341 is up and running Have just worked 4o3ant for a new DXCC in
antarctica. it is working great .now what should I add to it the auto
atu the dsp unit ?
Don't get too excited. The stations on this week with the suffix ANT
are indeed celebrating
Yea, I know, we've discussed this before. I'm not going to ask a
general question because it is too easy to get into an apples to oranges
comparison. But I've had the K1 for a bit now and have become familiar
with it's performance and operation. Now I have a better basis for
understanding the

My K2 has developed a strange problem when using the keyer on CW. If I
press and hold the paddle for dashes, it sends a string of dashes
correctly. If I press and hold the paddle for dots, it will send only
one dot, then on releasing the paddle, I hear 2 lower frequency dits and

1. How do the IF filters in the K2 compare to the audio filters in the K1.
I can't address the K2, but the variable bandpass filtering in the K1 takes
place in the IF crystal filter network. The audio filtering is fixed.
5. Knob wobbliness. The knobs on my K1 are just a bit wobbly.

You have the keyer set to the automatic detect mode and it act like a
straight key when you hold both paddles closed. Tap the menu key and rotate
the vfo knob until you see inp. Press and hold the menu key to edit and
then tap the display key this will toggle the adet (Auto Detect) on
What does it take to make a K2/100 run QRP?
- Turn down the power? (fine for CW what about SSB?)
- Unplug the KPA100 and put the old top back on?

Turn down the power. At 10 watts output the KPA100 shuts off automatically.

I assume they provide more selectivity and greater stop-band rejection. I
also assume the multiple IF stage filters in my Omni will provide even
greater selectivity.

Sorry Chris, 4O3ANT is YU for DXCC. It's a special
call participating in the WAP program. In fact, most
if not all of the suffix ANT stations are located in
the country of the prefix. That being the case,
VP8DJK, R1ANN and DT8A have all been active lately on
80 thru 20M CW.

Wow guys, Thanks so much for all the info.
You've answered my Q's in style and I now have all the info I need.
K2/100 sounds like a near perfect rig for my needs, time to get one.
The Omni V.9 is going up for sale. We have a ham fest once a year and
it is this weekend. I was going as a buyer
At least two ways. One unplug the power connector to the KPA100 and use the
old round power connector on the K@ it will auto detect and go into QRP
mode. Two, go into the secondary menu and turn off the KPA100. Of course you
can also remove the KPA100 and install the QRP top but that is really

That sounds unusually high unless the ambient temperature around the K1 was
changing significantly or the DC voltage was
I assume you are saying that you'd like to have a smoother VFO for the local
oscillator in your K1!
The K2 does NOT use a multiturn pot for the VFO. A K1 does. The K1 is a
totally different rig. The K2 uses a high-quality optical encoder for the
main tuning.

My K1 is very sensitive to placement. If I pick it up or turn it upside
down, I can hear it shift up or down in frequency. If I move a speaker
near the rig (or a PS) it moves a lot. If I just leave it alone it
stays right on frequency.
Does this sound like normal behavior?
- Keith KD1E -
It is sensitive to electromagnetic fields (speaker, rotor control, and PS)
if they are closer than about a foot or so. So is the K2. But mine isn't
sensitive to orientation. Maybe orientation puts it closer to an em field on
your operating desk.

When I have the K2 set for the 10 Hz tuning it sounds pretty smooth
to me, but if I have it set for the 50 Hz tuning (as I usually do) I
can very clearly hear the steps as I tune up or down past a CW signal.
I've also heard that on my K1; with very narrow signals and while

Try adjusting L4A while monitoring the voltage at TP1. Sometimes the
oscillator is balky if the inductor is set at the wrong value.

I stand corrected!
While the K2's local oscillator moves in an analogue fashion, the encoder
steps under the control of the optical encoder according to the tuning rate
setting. The minimum tuning rate is 10 Hz.
And, as Stephanie (VA3UXB) observed, if one chooses a larger tuning rate,

The other side of C18 will require an RF probe to measure a voltage.

Actually, I am quite happy with my K1 tuning. It is the one area where I
like the K1 better than the K2. I like the smooth, analog tuning of the
K1. I replaced the original multiturn pot with the metal shaft one that Don
Brown recommended. The tuning is the same, though. It just gives the
My K1 is very sensitive to placement. If I pick it up or turn it upside

Anything that squeezes or otherwise distorts the K1 bottom cover plate (such as
when the case is grabbed during repositioning) will cause a small frequency
shift (I see

Mike... That reminds me. I noticed that too. Whenever I picked up the K1
and sqeezed the bottom it would shift maybe even more than 100Hz.
There was a small double sided sticky tape covered hard rubber piece in my
packing material. I never saw what it was for in the instructions or if it

Hi
If I remember right that 1/2 inch rubber with the sticky tape on it is used
as a spacer for the LCD display. You are supposed to stick it on the pc
board under the display and then stick the display to it and then solder the
pins. I have not built a K1 lately (although I have built several)
I have been reading these messages about the drift and or change of frequency
when you move the K1. So, I just turned my K1 on for a few minutes and it is
just as solid as a rock. I turned it upside down and moved it around but no
change in frequency. I figure I should be happy about that!!
I am trying to troubleshoot a receive problem with my K2 that is driving me
crazy. I have lost the RX above 30m. On 20M I hear a low tone growl, but
on 17, 15, 12, and 10 I hear only a hiss (white noise). However, signals on
160M, 80M, and 40M sound great, but signals on 30M sound weak.

Well-known contester Bob Patten, N4BP, offered to help us improve the

Verticals are probably preferred for tight locations, and in any case have a
nice low angle of radiation even given ground mounting, or low elevated
mounting. Of the two, if you can get the antenna up six or more feet, so
much the better. Then you could use gull wing elevated radials to

Gents,
I've received many interesting suggestions and lots of help on my antenna
query. I thank all who emailed me here and directly to my home.
There seems to be as many thoughts on antennas as there are Amateurs.
Thanks again.

Thanks for the many comments. The 6 foot length was my real concern.
If the K2 can live with the .14 volt drop then all is well.
