This is Yucky. He lives in the top bathroom. He's 6 feet tall.
An externally hosted image should be here but it was not working when we last tested it.
And of course you found one of the couple of documents that do talk about it, by B&K, who are the only people who talk about it.
Note that the focus is on high pressure behaviour, the "mounted on the edge of a bit of drum kit" location, not what happens in a normal recording environment. In fact, that is what the literature is about - what happens in extreme recording situations.
Note that there is no information actually available, for a person who wants a microphone, about what its distortion behaviour is. Caveat emptor ... perhaps, buy an expensive unit, subject it to some tests, then take it back and claim a refund because it's not up to scratch ...
Interesting, I see the BSP reading rising a touch more ...
Absolutely right.
The manufacturer closed their plant in Chicago-ish and moved it South. The before the move cable is flat, the after the move cable isn't.
I do not read the bumps as uniform. I see two periodic issues. So while dropping a spool might be an issue these spools are not exactly small. (1500' put up of .475" diameter cable at 200 LB.s per spool.)
I read it as the center conductor is not staying centered on two axis!
Each bump is about a 5% mismatch of the nominal 75 ohm cable.
... with all colors of the spectrum, from infra-dead to ultra-violent...

How are you connecting the TDR and end termination, and more particularly how are you connecting the second shield ?.
Dan.
My previous indoor Yukkas got too leggy. I'm on cuttings off them now. That is a fine specimen.
Hmmm, how were the reels transported....standing on side cheek, or laying flat on edges of the side cheeks ?.
What temperatures have the reels been subjected to ?.
I have had troubles with tv coax that was oval shaped.
Not sure if it was squashing due to transport, or wound onto the reel whilst still overly warm and compliant, or wound too tightly and taking that 'set'.

Well guys, I have been shown a REAL FIND in audio preamps and I actually have one to test. It is made in China, called a JC-2, because it has copied the original Levinson JC-2 line stage, sometimes talked about and built here. It has an R-core 30W transformer AND some sort of regulated power supply,(more later on that), 3 double pole quality relays for line switching, and multiple multi-turn pots for offset, and bias adjust. It also has a 2 channel Alps (blue) pot. WOW! There is NO WAY we could make and sell this for under $1000 or so. Guess what? It costs $126+$30 shipping. The case is well made, (not Blowtorch quality) but very nice, with a milled front panel and off-on switch in front with an led indicator. (more later)

It is the right preamp, but a different vendor, apparently. We paid $30 for shipping, I am pretty sure. There IS a 110V version as well. That is what I have. It has what appears to be 2sk170-J74 differential pairs in each channel. All discrete. No obvious problems.
Here's a close-up of the PCB, its selling quite well over here (36 shifted in recent weeks) on Taobao, price about $100. PCB alone, go here ($25) - ·ÂJC-2Ç°¼¶Ì×¼þ ºÚ½ðÖÕ¼«°æ±¾ ´ø3λÊäÈëÑ¡Ôñ-ÌÔ±¦Íø

I thought it would have more compromises. OF COURSE, it is compromised somewhat in several ways, but they would be subtle, and usually fixable, if someone found it important enough.
