Build Update:
Pretty much finished with the dual airtrack. This airtrack is MUCH more stable than a single airtrack, and these newly drilled holes work perfectly. Here are some images and a video of the airtrack in action. Warning, loud noise in video. I hope to move the air system into the adjacent room once I purchase some longer hose.
I need to work on the interferometer next. I've decided against building it into the frame of the airtrack as that creates more difficulty mounting things on a vertical surface. The interferometer will now sit to the left of the airtrack on its own aluminum plate table, in the standard horizontal configuration.
I had the idea to build it in my local fablab but because I am doing this in my free time beside ph d work due to lack of time and money I stopped sometime in the planning phase.
I still would like to do this because I would really like to see a 10+ kW Klystron with feedback loop in action in any of the frustrums build by the people here.
Actually recently, being curious and willing to work full time on the microwave resonator concept, I sent an application to SPR Ltd. (Shawyers company) because this would be the only way to have enough time to pursue all projects.
I sent my formal and complete application to

Does SPR exist after all? If they do, can't they show the decency to send a one sentence mail that they are not in need of scientists and engineers?
A lot of questions.
SPR does exist, but they have no money and are inoperable as of late. Check back in my posting history just a few posts and you will see a fairly extensive write up I did about it. They aren't in need of scientists and engineers because a company has to actually be doing things to need scientists and engineers, and much more importantly they need to have money to pay said scientists and engineers.
That said, as Rodal mentioned they may not have got your application. You could try sending it too:
Oakways

That is the location of SPR's registered office (see
here), i.e. the place where they would receive mail from the British Government, so I think if you sent your mail there you would definitely know that it had been seen by someone from SPR. It is also the location of Sheridan Strategic Services which is a sort of business manager for SPR, so whoever receives it will be sure to pass it on.

Looking for the registered address I found this website with lots of public information on this UK company:

I just have to point out something from the Horizon Greenglow episode. The following is a brief transcipt of the first emdrive segment, which begins at the 29:45 minute mark.
Shawyer: The big advantage of emdrive is that it’s a device which creates a force but it doesn’t have to shoot out a propellant out of the back.
Narrator: Instead of using rocket fuel to create thrust the emdrive uses microwave energy, just like a domestic oven. Microwaves bounce around inside the box in waves cooking your food. To stop that energy cooking you, there is a mesh on the door with holes in it.
Shawyer: The diameter of these holes is so small that instead of going through it, microwave radiation is actually bouncing up and down vertically in the hole.
Narrator: The holes trap the waves, slowing them to a standstill. According to Roger, the narrow end of his emdrive does exactly the same job.
Shawyer: The waves are going faster at the large end then they are at the small end. This means that the force at the large end is greater than the force at the small end, which will cause the cavity to move in the opposite direction [shows the device moving small end forward].
Emphasis mine. Kind of sad that no one involved in the making of that documentary, whether it was the director, or one of the contributors, or someone in the editing room, or even the freaking camera guy didn't call those out. If Horizon is going to try and make scientific documentaries, they should invest in an editor who has the scientific literacy to realize neither of those statements are even half way correct. Including an obvious misapplication of F=ma is just embarrassing.

Shawyer's lab is a reasonably sized building. Does anyone have an opinion as to how much it would cost to lease such a building? (SPR is as mysterious as the EM Drive phenomena...)

That is a good website compared to most. There are many such sites that take the information from Companies house and essentially create a separate front end to view that information, where they hit you with advertisements and even make you pay for previously filed material (like statement of accounts). Note that under the section titled "Documents", you can pay 0.99 pounds for Annual Accounts and Annual Returns which are freely available directly from Companies House! Furthermore, many of these websites don't even have accurate information compared to the most up to date info from Companies House.
That said, the plot of net worth does agree with what I previously found.
Concerning your second point, I doubt SPR will take on new blood. A company that has been a one man operation for the last fifteen years probably isn't about to break rank and start taking on outsiders. If Roger chose not to hire people when funding was more plentiful and the emdrive was a blue sky, I don't see him taking on people now.
When was the documentary taped/filmed?

...BBC Horizon EmDrive episode. Roger told me Horizons filmed the SPR segment last week. They had already filmed the USAF and UK Dept of Defense segments before they filmed the SPR segment...
so according to TheTraveller it must have been filmed
the first week of December 2015, just over 3 months ago.
Roger advised me the video was done at a SPR licensee and not at SPR. Was also told he could only show thrusters older than 5 years.

Are there drives newer than five years?

In the photo below Mr. Shawyer's rotating demo can be seen in the background. Why didn't he start it up and let BBC film that? It's over 5 years old. Also next time you talk to Mr. Shawyer can you ask him what the large bird cage apparatus is that hangs from the ceiling above him in this photo. It looks like it has fan blades on it. Why is it suspended from the roof beams?

It is my understanding that area was storage for old thrusters and other equipment. The EmDrive shown was 2008 tech. As for the Demonstrator, there is already a video that you can view on
www.emdrive.comDo believe a early cryo EmDrive was originally videoed on the air track. Was surprised to see the very old pre Flight Thruster on the air track. Do note the episode was scheduled for late Feb but was pulled and nothing was shown for the last week in Feb. Finally was shown late March. Wild guess was the cryo unit was replaced at the edit of USAF or UK MOD.
Would also add Roger said BBC did film both USAF & UK MOD but neither interview made the episode.
BTW who is "Coyote"? Seems the BBC left us a trail to follow.

Which is it? A licensee site or a storage area that SPR uses? Also what is the fan hanging from the roof beams used for? It looks like there are some spot lights around it. Is this another experiment that Mr. Shawyer is doing where the fan and spotlights are turned on? If so, what would be below the fan and illuminated by the spot lights?

It's 5:14 AM and as you can see I did this all by hand.
***Important to note: the frustum is "upside down"per the way it copied off the site.
***Also note: the top plate is raised all the way to the top of the frustum, and the bottom plate is raised
to it's highest position. Of course both plates could be adjusted in combination.
It appears as though Yang could adjust up to a little over 2 and 1/4 wavelengths. , Fatty Lumpkin

I think I can see, where this whole thing is moving. Mr. Shawyer will get older and older, and suddenly he will be gone. Meanwhile, decades will have passed and no credible demonstrations been made. Just another story of someone who could have changed the world for the better, but didn't, because.. reasons .

Yang's fustrum dimensions were previously discussed in previous threads. For comparison, a previous estimate (see:
http://emdrive.wiki/Experimental_Results ) was
Length = 0.24 m
Big Diameter = 0.247 m
Small Diameter = 0.114425 m
Cone 1/2 angle = 15.44 degrees
Your dimensions:
has identical:
Length and Cone Angle
but very different small diameter (your calculated small diameter is twice as long)

If any replicator reads ALL of what Roger, Prof Yang & myself has shared they will suceed. If they modify the recipe, well they are skiing "Off Piste" & good luck.

The best way to demonstrate Shawyer's technology (and therefore to get funding
to enable Shawyer's dreams for the EM Drive) was proposed by TheTraveller earlier in these EM Drive threads: to have the experiments demonstrated before a skeptical audience that could independently observe and assess the experiments. TheTraveller had earlier proposed to come to America with a rotating battery-powered unit that he would demonstrate before audiences. Such demonstrations could change skeptical minds and get needed funding.
Presently we see Mr. Shawyer all alone and SPR Ltd. is reported having negative net worth since 2008 (
https://www.endole.co.uk/company/04097991/satellite-propulsion-research-limited).
It would have been much more effective to demonstrate the Demonstrator EM Drive rotating around before the cameras of BBC Horizon. For example, the BBC could have had the aerospace engineer Dr Ron Evans (who appears repeatedly throughout the program except in the Shawer segment), and/or Nasa aerospace engineer Marc Millis (who is skeptical of the EM Drive as per previous reports), and/or Dr Martin Tajmar (who appears in his own segment) and/or Prof. John Ellis (who expressed skepticism) to be present for the Demonstrator being shown going around and around (instead of being shown in a video).
Also, is there a video of the Demonstrator shown rotating around that shows a large perspective, including whether anything that was in the ceiling? For example, concerning the fan hanging from the roof beams, if such a fan would have been operating on top of the Demonstrator, such a powerful fan may have had an influence on the rotational movement of the EM Drive Demonstrator below the fan and illuminated by its spot lights.
That's why
TheTraveller's proposal to demonstrate these devices before skeptical audiences makes so much sense to get funding and revert the present situation of Mr. Shawyer shown all alone pushing the EM Drive by hand and SPR having negative net worth.

What part of what I have shared don't you undetstand? I thought I was very clear in retelling what I was told?
Here is the bottom line:
The filmed area was not SPR.
It was a storage area for OLD tech which included the air track.
Nothing was shown that was younger than 5 or would violate DNA or contractual obligations.
Both the USAF and UK MOD had edit rights.
Ask yourself why "Coyote" was included?
