the Rowridge listings are starting to be so confusing..
i am now able to watch HorrorExtra using my Windows box running Hauppauges (sp) Dual HD usb tuner stick, with the WinTV tuner software from Hauppauge.
this station shows up in listing on Kaffeine on my Linux box, it tunes in, sort of, but doesn't play properly. however... according to Kaffeine it is on a Mux being broadcast on 506MHz. but isn't included in the listing above.
how do i find a current definitive listing of what the ...flip.. is being broadcast from Rowridge at this moment?

tony: Freeview has published here is list of all services on the platform:
Channel listings for Industry Professionals | Freeview
For Rowridge, the multiplexes are:
PSB1 BBC A C24 498MHz
PSB2 D3&4 C27 522MHz
PSB3 BBC B C21+ 474.2MHz
COM4 SDN C25 506MHz
COM5 Arq A C22+ 482.2MHz
COM6 Arq B C28 530MHz
PSB3 and COM5 on C21 and C22 respectively have a positive offset, meaning they are +0.2MHz above the centre of the channel. The receiver may or may not show the ".2", but assume it to mean the same thing.
There is also the local multiplex for Southampton, broadcast on C37 (602MHz) from directional antennas pointing in the direction of Southampton.

Each week we get a new posting about engineering work on Rowridge transmitter.
this has been going on for some time now. What are they actually doing and how is it going to improve my TV reception. are they likely to boost the power on the remaining 3 muxes.

TIM wardlaw:
As far as we know, it's routine maintenance. Arqiva never giver details of what the work entails or how long it will last as some of it may be weather dependant. Clearly such work is better done at this time of year when weather is not so inclement. It's a good ten years since DSO and one would image that most transmitters will need a lot of maintenance checks etc. This isn't the only transmitter where works have been running on and off for several weeks.
It's very unlikely that will be any change in transmitted power as these are subject to international agreements.

TIM wardlaw: I think the best course of action to "hopefully" get good reception for COM4-6 is to switch to vertical polarity, this if you haven't already done so. The word "hopefully" is in quotes because with reception issues there is never a guarantee, and that in this instance it would seem reasonable to conclude that the higher-power VP signals may solve the issue.
Looking back at earlier postings, you have spoken on the saga of Rowridge HP versus VP. Since COM7 and COM8 were turned off, there is no longer any HP-only multiplex, with the exception of the Southampton Local TV one, broadcast in the direction of Southampton.
You have previously given your location as New Milton, and the Freeview Detailed Coverage Checker does not even suggest the Southampton Local TV multiplex as a possibility for your postcode, hence why I suggest it is probably and open and shut case for switching to VP where HP is not satisfactory.
Rowridge, uniquely, broadcasts with both horizontal and vertical polarity, having done so since digital switchover in 2012. PSB1-3 are 200kW HP and 200kW VP. COM4-6 are 50kW HP and 200kW VP.
It occurred to me at switchover that Rowridge had effectively become VP, with the HP transmissions more for legacy purposes, to serve those whose aerials had not been reoriented from horizontal. Subsequently, of course, the HP-only multiplexes of COM7, COM8 and Southampton Local TV threw a spanner in the works, creating a dog's dinner whereby some viewers would have faced the choice of switching back to HP, and possibly having to sacrifice good reception on one or multiplexes to benefit on one or more others.
The power of 50kW for COM4-6 is in no way "low", many main transmitters not even reaching such. Being so close to the transmitter as you are, I wonder if the trees in your vicinity in the direction of the transmitter are shadowing the signal for you, hence poor or variable reception.
The most likely reason for the lower power HP COMs at Rowridge is because they are co-channel with the COMs of Stockland Hill and Crystal Palace (both which broadcast only HP). The PSBs of Rowridge with these two transmitters are not co-channel.

Is this engineering work the cause of occasional short-lived dropouts on PSB3 channels from Rowridge with a black screen and a 'no signal' message? I usually get a strong signal so these dropouts are an unpleasant surprise.

R Murchie:
As the report says "pixellation or flickering on some or all channels", so that is highly probable.
If the "flickering" is a brief drop in signal, then getting a no signal message wouldn't be unexpected.

Transmitter engineering: today 7/10 having virtually no tv reception on freeview channels. Its Saturday usually watch sports. Today nothing. What the hell is going on? I don't pay my TV licence to put up with this crap. So apologise and restore today
