Below are all of david's postings, with the most recent are at the bottom of the page.......further investigation reveals that the channels they cannot get are all on ArqB mux - iu.e. the one that is running on lowest power so yes, they will have to wait until Dover goes DSO........still wondering why the freeview site seems to think they are served from Dover though.
Never thought I'd be saying I'm glad WE are served from Taccy :)
Thanks for the reply anyway

Just a thought but I did not receive an email alert for the answer from norm de plume even though the forum said I am set to receive email updates.....ideas ?

Is there a problem with Mux A group.....we are getting good signal strength but mega high errors on all channels on MUX A, all others are OK.....noticed yesterday

Dave L,
Thanks for the info - I did in fact see that but couldn't break it down to individual muxes and, as ALL the others are perfect assumed it wasn't the cause of our problems.......the situation remains the same today.
....ps....I didn't receive email notification of your reply, the "email me updates" box is ticked .....

OK so now there doesn't appear to be any ongoing transmitter work.....but we are still experiencing exactly the same level of errors on all channels on mux group A. All the others are OK with no reported errors *. Up until this started we could receive all channels with no errors *
* as reported by the TV and freeview indicators

Norman,
Fly lead between wall & TV OK ?
I proved black was blue a while ago after purchasing some so called "digital" gold plated blue sheathing fly leads and "lost" several channels .....no, I didn't believe it either but replacement with leads made up with CTT100 cable made an immediate and somewhat un-believable improvement !
I think the problem was that rather than being faulty, the cheap leads allowed some interference in which was swamping the signal and causing the loss.
Might be worth a try.......I was so impressed I re-cabled the whole house in CTT100 cable, from aerial to outlet to TV and now don't get any interference or drop outs at all :)

In response yo my post on 3rd June ....... the problem we are having affects the Com4 / SDN mux transmitting on channel 42 and NOT mux A....somewhere along the line I got confused with the numbering and referred to the pre DSO mux group ....apologies to all.
By LOWERING (!!) the aerial about 4ft I managed to get the signal strength on chan 42 up whilst the others dropped by a few uV so I now have a more even spread across the channels.
The tx is 208m high and 64m above sea level, my aerial is about 11m high and we are 40m above sea level so I have angled it up a few degrees which also helped slightly.
What I can't understand though is if they are all coming from the same transmitter and all leaving at 100KW then why are we receiving them at significantly different field strengths and why did lowering the aerial increase it ?
I have always believed that higher = better with a 3dB increase for every 6ft higher.

Clacton-on-sea
I am trying to assist some friends who live in Jaywick, Essex and after DSO last year lost some channels that they could previously receive OK.
They are definitely served from Sudbury (despite the freeview reception site that says Dover) and all neighbours aerials are pointing that way as well.
Based on my experience (from Tacolneston) I advised them to remove their aerial amplifier and re-scan etc. but it didn't help.
The "main 4" are OK - sorry but I don't know which ones they are struggling with so will try and find out & update this post.
thanks
