Hi Vic,
You certainly have lots of RF in the shack, with your shack only six
meters below your antenna, everything in it (including you!) is part
of your antenna especially on the low bands.
Please be sure your personal RF exposure level is safe

My shack is only about 6m below my antenna, and although there is a
concrete roof between us, I had problems of RF pickup in my computer. My
antenna is balanced, I used a lot of ferrites on the cables, and bonded
all of the equipment together with copper straps. But the biggest
improvement
And when Bob, N6TV visited my station, the asked, "Why aren't
you using a spade lug for K3 ground?" I could only say, "Duh!".

Why try to connect the wire or braid directly to the ground lug?
Soldering a lug onto the end of a wire or braid makes it "oh so easy" to
attach.

Mark:
I have the same configuration. When you transmit into the dummy load,
what mode are you using? If SSB, there is no output until you speak
into the mike with the correct audio settings. TUNE mode is best for
checking to see that all is working.
I suggest you see top of page 66

No need to waste a lot of time on this. Set all to 38400, the default speed for
the P3 to work well.

I'm a new ham... I just purchased new KPA500 and KAT500 to use with my new
K3S/100... following the wiring diagram of the KAT500 manual, page 5, figure 1,

Yes, it is a hassle getting a stiff copper wire on that little ground
screw. I use 1" braid with a strip of copper sheet folded and soldered
over the end and a screw hole drilled through-- basically, homemade flat
terminal lugs on the ends of the braid. Very easy to manage now.

Yes, but NEVER used braid exposed to moisture.

Hi all,
Using my home-made RS232 sniffer in order to capture K3s frequency
information while my K3s is exchanging information with Wintest I found some
non-obvious behaviour of the PC - K3s USB baud rate that might interest
others as well.
The set-up is PC USB K3s RS232 P3 (PC port of
Hi Lee,
When I got my K3 I rebuilt my shack from teh ground up, starting with
the ground, with an eye to reduction of RFI. I took a lot of Jim's,
suggestions, and I lost about 2 S units of noise. That process is
detailed here:

I wish I had done that when I set up my shack in the home I bought when

I added two large washers over the post. Makes it easier to sandwich the
ground braid between them. Poke a hole in the braid to go over the post.

I bond each piece of equipment to a common ground terminal on my power
supply. I do not have any ground from the station to the outside. Only
the 3rd pin safety ground is in place. The station is fed from a
common 240V 4 wire service for the amp and other related equipment.

Ok, I just rebuilt my station and wonder how many of you actually ground
your K3 or your rig? I have the amp and tuner grounded, but I find
grounding the K3 somewhat difficult. Why? Getting my fat ham fingers to

Rich,
Not quite. You do NOT want to connect the CBLP3Y cable to a USB to
serial port adapter. You will not only have communications failures,
but you may damage the K3 USB port output and the USB to serial adapter
because you will have two drivers on the same RS-232 signal lines.

Hi friends, is anyone with experience working the Elecraft K3s with a
linear amplifier Kenwood TL-922 or with a linear amplifier Drake L4B?
Has anyone used the AMERITRON ARB-704 Universal Amplifier Interface to
connect the K3s to any of these linear amplifiers?
I appreciate any information about
