John,

If you can't find used, DX Engineering sells the Nanuk brand. Very similar to Pelican at a fraction of the price. I use one for my surveying data collector and it has protected it from some VERY embarrassing episodes out in the field. For the quality they are extremely reasonably priced compared to others. Many sizes and good padding.

Just a suggestion.

I found a military case on eBay I am happy with
It was about $30 plus shipping

It is not quite as sturdy as a Pelikan case but close enough.
It should survive most things the airlines would throw at it (pun intended)

It fits the K3, P3, and a Scarlet Solo plus mic, cables, etc.
I modified the foam liner of the case to fit the K3 and P3.
The interior is still a work in progress.  

It has 4 clasps (one on each side and two on the front)
It does not have tabs on each half for locking but a little creativity might fix that

23" x 21.5" x 6.5"  (W x L x H) 
approximate exterior dimensions
I will try to figure out the part # for the case

You may also consider turning the "delay" knob on the Signalink up (clockwise) a bit.  I don't know if that affects the signal quality, but it should eliminate excessive Tx/Rx switching.

Cable trays like those are available in the UK from most electrical wholesalers.

Front panel design is administered for Europe (inc. UK) by Schaeffer in Germany: http://www.schaeffer-ag.de and their service is excellent, if perhaps a bit expensive for one-offs.

Front Panel Design does take some getting used to, but once you learn how to use it, it's very powerful and accurate. and you can submit your design direct to Schaeffer.

I designed a new case for my 2 metre linear and submitted it to them. It was made and shipped in about 2 weeks.

Re: Latest on the new home for my K3...

Nicely done.  I too have done a lot of homebrewing in my younger days and built a number of high power amplifiers.

While getting panels built to order is marvelous, a careful homebuilder can do much of this in the home workshop, it just takes longer and costs less.  The engraving of nomenclature on panels is probably the biggest problem in the home shop, although I used to have a panagraph engraver and even did this at home.

A couple of my projects can be seen at the bottom of my QRZ page (I've never had much desire to build my own website). https://www.qrz.com/db/N7WS

Some of the work was "G jobs" at my former employer, where I had access to a metal shear and metal plating equipment but I have done the same work at home.  One trick for box construction is using flat plate construction with corner blocks (something I was doing before Elecraft existed ;-) 

Hard alloy aluminum of sufficient thickness can even be cut on a table saw using a fine-tooth carbide blade if one is EXTREMELY careful.  Otherwise, using a hacksaw and files will do it.  A very nice satin finish can be had by using a random-orbit sander and lubricant.  Experiment with grit to get what you want.  Follow up with a soak in a household lye solution, then a vinegar dip and water flush and it will look professional.

I did layout using machinist's blue and a vernier height gauge on a granite surface plate, but hand-holding an inexpensive vernier caliper will do the same job.  Purists will drill and tap the plates and corner blocks individually, but match drilling works fine and is a lot less grief.

I had access to Alodine and silver plating but I don't recommend either.  Poorly done, they both can affect RF conductivity in a negative way.

Re: Fell Hell

Mike Flowers
 

I think Feldhell is especially sensitive to having good modulation of your tones on TX.   Over/under modulation of TX tones might well contribute to missing or distorted text being received.

 

On a K3, ALC for most digimodes should be first four bars solid, 5th flickering.

 

What does your ALC read when transmitting Feldhell?
