Chris.SE: Well, the Mendip Coms soon went but I managed to grab some transport stream samples and read the SI tables out of them while they were up.
I also did a CrazyScan spectrum at the tail end of it:
tropo ImgBB
The image is of the active tropo scan - coloured red - followed by a scan made tonight, followed by a superimposition of the two that shows the difference.
Com7 appears as an undecodable lump of carrier at 746 MHz in the top scan.
The Hisense telly still reported C55 as 86% strength with zero quality.
The s/n of BBCB, on 586 MHz, at 27dB, was down from 35dB - presumably due to CCI from Mendip.
The Mendip SDN peak at 690 MHz is impressive.

The 8PSK modulation parameter change is from 23000 3/4 to 27500 2/3. It will be interesting to see how Freesat devices cope. Pick (HD) had this modulation but there were no reports of any problems. There have been reports of problems in the past of Panasonic TVs in particular, and currently LG, having problems with ITV HD.

I usually use the Service Information (SI) tables off a BBC transponder, but it shouldn't matter as all transponders on ASTRA normally carry the same SI.
Having recorded a TS sample off 11097V for the Bitrate analysis, I happened to read the SI out of it and found that the SDT off it is missing an entry for TSID 2044.
Thus no service names are available, using the SI off 11097V, for the services on:
10758.50 V 22000 5/6 DVB-S QPSK 28.2E TSID = 2044

Now getting perfect reception of all three Mendip Coms on C48, C33 and C36.
Com7 is completely gone.
