Actually, I'm wondering whether ch23 (analogue itv) is temporarily being broadcast from a different physical location (a different point on CP's tower, or maybe it's being relayed from Croydon?) while they get set up for post-DSO channel 23... I've always suspected that our poor ch23 reception was caused by our aerial just happening to be in a node for that frequency. An aerial a few feet away from it does fine, so even a very slightly different signal source location would change things. Anyone know?

Wow. As of just this minute signal has dropped back to its "normal" level, i.e. 72% and virtually unwatchable. Guess CP's DSO tech guys are clocking off for the day and have to put things back to normal for the night...

Just read that Croydon has, indeed, always been set up to run as a backup for certain Crystal Palace channels, including ch23 - so it looks like the DSO engineers are using Croydon for ch23 during work hours as they get CP's ch23 transmitter ready for when it will be used for the BBCA multiplex.

An OTA software update for my Humax 9150t recorder is scheduled for broadcast on MUX1 (ch25) from last night until tomorrow morning, by my machine isn't finding it. Does anyone know whether CP has suspended sending out OTA's for the present time?

Doh... just realized my machine is a 9200, so no wonder it doesn't load the software update currently being sent out. Think before you type next time, Chuck...

Happened to notice that CP seems to be experimenting with ch22 (analogue ITV) signal strength lately. Daytime strength as measured by our system (in North London, line-of-sight except for pesky City of London towers halfway between us and CP) has always been in the the low 70s (in units of percentage of ideal signal? Who knows... Anyway, below 80 on analogue frequencies results in a very poor, unstable picture) but is suddenly now in upper 80's (perfect picture). Nighttime strength is back in 70s. Weird.
