Is someone had old spectrums of the 129W ?
My last SS numbers from end of 2008 shows eight empty tpns: 14, 15, 20, 24, 25, 26, 28, 29, but today only five missing: 18, 22, 24, 25, 29.
 
Spectrum of 129W taken from D1000+ today with both polarities - even tpn's freqs are inverted.

The problem is that E5 is oscillating in more than one plane. If you watch it for a while everyother even or odd transponder will change signal faster than the adjoining even or odd transponder. The fluctuating signal strength and the fluctuation between transponders makes the data very difficult to use. About all I see so far is that the dead transponders continue to be dead.
 
Just for compare apples ie dishes: D1000+ tp16 show 26...29%|95% levels using same TH1020 PCI card.
While TH1020 at 31...33% SQ, a 622 show steady SS=30 for the tp16.

There is skyscan for 9:11pm - 8:23am PDT last night. Acquisition rate was 2 times per minute.
Bottom line show TT&C activity. Post #4 shows corresponding tpns - tpn1 at bottom, tpn2 at top of skyscan picture.
Next run will be for 24 hours.

I see a little fly spec. But, Smith you got to explain it a little. I like this stuff and totally do not understand what I am looking at.
 
You should be excited everytime Smitty puts up thumbnail. Now you better stay on topic or you will get slapped by him.

Well, it's pretty easy; you could see same on Fred's site here.

X ax is a time, Y - freq, bottom low freq, top - high.
Now imagine a picture in post#4 had inverted colors, so high signal level will be bright white, no signal - black. Then rotate the picture counterclockwise for 90° . Making samples 1 or 2 times per minute and combine 15000 of them into one picture. Voilà - you see the skyscan.
[Anyone who interesting in BLSA could find them quickly - use my PM.]

Added a picture from post#4 with inverted colors. ;)
