anthony: "Possible weak signal [DUK]" is next to useless as date/time, duration, reduction in power and affected multiplexes are not given.
In the last few months I have been recording items off (Winter Hill) com7 during the daytime and have become all too aware of periods of reduced power, which have resulted in failed recordings.
On every such occasion both com7 and com8 were down by 6dB, other multiplexes being unaffected.
Here are my reports for two such events, in a week wherein they happened daily. (Given previous experience, I started logging at 9am, continuing until power was reduced and again from 4pm until power was returned to normal levels):
Winter Hill Reduced Power:
com7, -6dB, 24 August 2016 09:05 to 24 August 2016 16:50
com8, -6dB, 24 August 2016 09:07 to 24 August 2016 16:52
Winter Hill Reduced Power:
com7, -6dB, 25 August 2016 09:57 to 25 August 2016 17:40
com8, -6dB, 25 August 2016 09:59 to 25 August 2016 16:58
The most recent examples of this kind of reduced power occurred Monday 19 September and Tuesday 20 September.
My loft-mounted C/D aerial is not optimal, but all ten multiplexes are normally receivable without error. A 6dB drop in power-output for com7 puts it at or beyond the cliff edge.

Hazel Taylor: IRISH TV, though not deleted, was removed from Freesat 163 on 28 Feb 2017.
Irish TV is available via BSkyB 191 and FTA receivers (including Freesat devices in non-Freesat mode), on 11686 V 22000 5/6 QPSK DVB-S.

Also note that generic devices with DVB-T2 demodulators (there as many DVB-T2 TUNERS as there are digital aerials) will fail to decode the BBC ENCRYPTED EPG for services on the T2 multiplexes, producing what is often described as "Chinese" programme titles/descriptions.
An advantage of such devices is their ability to record programmes as transmitted, where "Freeview HD" devices will encrypt them to disk.

Shocked it is I am!
In what must be the biggest infrastructure change to Freesat since its creation, the Freesat "Home" transponder has changed as shown below.

I was very lucky to see the Freesat Home transponder change test.
Unsurprisingly, it seems no one else spotted it.
Obviously, it's not of interest to most but of great interest to me and a few who keep an eye on sites like this.
Fortunately I made some screen grabs.
New Freesat Home Transponder Test - Album on Imgur
Looking at the picture, note the inability of TSReader to measure the multiplex bitrate for the test transponder.
This is because there were no PCRs on 12509H. There is an encrypted video stream on 11427H which is a PCR source.
The test transponder was still working 11 May 2017, 10:28:44 - the time of the last screen grab I made of it.
It was really odd to see 11427H devoid of anything Freesat, carrying a NIT with some arqiva network name.
Unfortunately, I didn't get a screen grab of that.
I did grab a 30 second dump of 12509H and there was a parsing problem, the cause of which I am yet to identify.
The Freesat TOT/TDT was late by about two days with the Freesat EIT and EIT p/f about two days old.

A peculiar BSkyB launch of "FrontRunner 2" occurred on Friday 26 May 2017:

This bizarre process has resulted in the Freesat "FrontRunner" becoming "FrontRunner 2".
What's more, the BSkyB "FrontRunner" on 11082H, which is not on Freesat, has the Freesat streams mapped to it and the BSkyB "FrontRunner 2" which is now on Freesat as "FrontRunner", does not!

We have lift-off for BEST DIRECT and a fix for the BSkyB Frontrunner bludner:

So now we have "Front Runner 2" on Freesat but no "Frontrunner" - makes sense don't it?
Still no Freesat streams mapped to "Front Runner 2".
A Freesat transponder move for "Frontrunner" would have fixed it.
Instead, Freesat have compounded the blunder.
