Paul: Just remove the amplifiers and, if possible, move the aerial to the roof.

I'm in the center of Aberdeen and have a call from Digital and they confirmed my supision that the low strength mux's from Durris are getting blarged from Balgownie (low strength very close) and they said they wee going to report it.
They also said that things will improve later in the Summer as Briantist says.

Briantist; I note your comments but I cannot seem to reconcile the fact that on this site it states that ArqA broadcast on ch41 is listed as transmitting power as 5000watts as does for ArqB however A is at 20000 watts this would lead me to think that I would have a better chance of getting decent reception on A but that is not the case as I do not now get any reception on CH 51 52 but get adequate reception on CH41 which includes Sky news and Sky 3 can you please advise if my logic is correct in this or am I missing the obvious. I also note that Ch 44 is the main ITV channels and CH 46 is the BBC channels they seem to be from Balgownie. I have tried manual tune missing out CH 44 and 46 but still cannot access CH51 52. Any advice would help.

Just noticed the Comparison of analogue and digital signal levels section. According to that C51 and C52 (which have all the channels I'm now missing)were on Mux B and Mux A with 10 and 20 KW before switchover. They are now on ARQB and SDN which are only 5kw! No wonder I've lost them, my signal is even weaker than before. Need to check what gain my neighbours amp is, hopefully more than mine which would make sense as to whys he's OK.

Paul: If you have any form of amplifier in your system, remove it. They usually destroy digital reception, not improve it.

I bypassed the masthead amp yesterday with the aerial only going to one telly, and DVD Video etc all switched off. Good channels saw signal strength drop from 90 to 50%, but channels from weaker muxs did not even appear after a rescan.

Paul: Don't worry about signal strength, it is the signal quality that is all important for digital reception.

Just to check - you do have a wideband aerial, and not a group A?

Thanks for taking the time to reply Briantist-don't fancy your job much, all grief and no plaudits! I am just going to wait until the Summer for Durris to 'settle down' then and see what happens? No point in trying to shoot for goal when the posts are getting carried about by the engineers! Cheers (nothing happening with Durris in Spring though?) Maybe we should all get out more and forget about tv anyway!

Grahame: It's not actually a job either, but some people do say thanks, which is always helpful.

I suspect waiting for the power-up on 15th June 2011 is probably the best thing to do.

Briantist, Yes my aerial is wideband. My setup was perfect up to the switchover and only started getting bad once the wetaher got worse. As I said earlier I tried removing my amp but no use as C51 and 52 channels not even picked up. The only difference between my neighbours and my setup was the amps. I checked his expecting it to be stronger which would explain why he was OK and I'm not. However his had less gain than mine. Then thought mine was too strong, and with the C51 and 52 now being weaker output, thought noise was killing them. So got a Labgear variable gain amp so I could reduce the gain. This didn't help with signal strength still under 50% for C51 and 52 programmes and quality going up and down between 0 and 100%. (Actually best with gain increased). Back to what's different between neighbour and me. My aerial was low in the loft to avoid pointing at the chimney between me and next door, so moved it up and down to get best signal. Turns out lifting it up only 1.5ft was best resulting in strength going from 48 to 65% for C51 and 52 programmes with quality 100% all the time. Result. Bottom line is that people have lost these channels as their output is weaker since Sept, which as you say will be sorted in June is willing to wait.

Thanks...Paul.

P.S I am going to hang onto teh Labgear 4 way amp anyway. I had a 10 year old Fringe outdoor 4 which has crap connections, higher noise, and probably not screened.
