How do I configure the K3 to accept audio from my PC sound card and use the
front panel mic at the same time?

Hi
I looked at this for a while. With many radios and often swapping antenna
cables and panadapters it was a nightmare just sitting on my table. Looking
on Kijiji, I saw lots of rack mounts complete with power distribution units
for $40 to $60./ I bought 2 and mounted them both on lazy
I use fixed rack shelves that have an inside dimension of 17.5". At
several Denver-area swap meets I have displayed the Elecraft banner with
the K-Line in a short rack cabinet. The K3(S) + P3 (on the right side)
fit on one shelf with the feet and the handle in place. No need to
remove
The ease of changing CW pitch in the K3 is indeed a great asset in setting
things up for best copy, and I have found myself using it quite a few times.
The immediate reason to change pitch has usually been a perception that with
the existing setting, the best copy pitch does not exactly coincide
I shared this a little while back. My solution isn't as slick as rack
mounting, but has a smaller footprint (about 14" x 14" or so) and great
ventilation. :-)

Looks like a common panel is not required anyway making it a moot point.

Was just brainstorming... Maybe as I posted subsequently, you could just bond
the two units togetger with additional hardware
Thermal issues could be dealt with by creating an efficient thermal interface
bewtween the units and adding a fan to the P3 to take the heat out the P3
mass
Fun part is mounting the P3 to the K3. Both side panels screw on from side. No
way to share a common panel.

Chuck and all,
Those particular inductor cores with the narrow slot are difficult to
break, and they seldom stick.
Since I adjust them during repairs, I would wear out many tuning tools
in short time. I bought a ceramic screwdriver with a 1/8 inch wide
blade. I have another with a 5/32
The last time I had to do this and didn't have a dedicated tool, I took a
Chinese take-out bamboo chopstick and carved it to fit the slug. It's
fairly easy to do and if you mess it up you just cut off that part and try
again. The bamboo is strong but easy to carve, and it's non-magnetic of
course.
It's about 16.75 inches wide if you remove the handle and feet from the
sides of the K3

Based on published numbers, the P3 is 6.1" wide, the K3S is 10.7"
wide. As I recall a 19" rack shelf is 16.75". If all is correct, a
real tight fit, I'd say.

A metal screwdriver might affect the inductance. There are several
inexpensive tuning tools made with a plastic handle and a small thin
metal blade, for example:

I used a similar tool when I built my K2.

Some of those things get difficult to turn and the screwdriver breaks the core.

This probably is related to the commercial CW operators trick of laying
the phones down on the desk to copy a weak ship station through noise.
It really does work. Unfortunately, today's over-the-ear headphones tend
to stick together rather than laying flat on the desk as the old "cans"
did,
One of Elecraft's vendors that does the heatsinks, SNS Engineering,
makes a complete line of rack panels that will do exactly as you want.
Matching black color, handles, strong and well made.
Call then at (831) 345-4590. I would attach a brochure, but this
reflector doesn't pass them along.

I have my KAT500 and KPA500 in a rack. I do it with shelves that mount in the
rack. Does not give it a military or commercial appearance but is as effective
as having a rack mount option. I actually like it better because I can slide a

I generally use 440 Hz for sidetone/pitch, thinking that it is a
familiar standard musical note and perhaps is more recognizable to the
brain in some way. I don't know if that has any validity or not...
