Does anyone have any suggestions which may help me?

I live in Chesterfield and before switchover (completed last week) I had no reception problems with Freeview.

I have two wideband aerials - an external one distributed to the downstairs rooms and one bedroom, one in the loft connected to a further two bedrooms.

Since switchover and retuning, something odd has happened. On the TVs connected to the outdoor aerial, none of them can recieve PSB2 (ITV1, etc)on ch23, all other multiplexes working fine with between 70 and 100% signal.

With the TVs connected to the loft aerial, none can recieve COM3 (Yesterday, 4Music, etc...) on ch40, all other multiplexes working fine between 60 and 80% signal.

So with the two aerials which worked fine before switchover, each now does not pick up a multiplex, but the multiplex missing is different per aerial.

jb38: Thanks for your advice.

I switched the aerials to the TVs around like you suggested and had the same result, the same multiplex was missing from each aerial.

However, I tried connecting the outdoor aerial direct to the main TV (i.e. bypassing the distribution amp) and the PSB2 (ITV1, etc..) appeared - although on very low signal level (10%), hence pixelating and not watchable. Is this to do with picking up too much signal or not enough before I purchase an attenuator?

SteveP - thanks for your reply.

Yes I am on Chesterfield. I appriciate that it is on low power for the time being, but both aerials worked pre-switchover when it was only putting out 20-40 Watts. The temporary low power is 40 Watts so I would have expected the loft aerial would work - maybe I am mistaken?

I understand from jb38 that it may be an issue to do with too much power on the external aerial which worked fine when the transmitter was at 40W but now doesn't at 400W.

jb38 - Thanks for your response.

I have gone through the signal detection as you suggested.

On the external aerial all the MUXs were correctly tuned for Chesterfield. The good news with this is when I looked at the amp to find out the model (its a Fringe 4-way masthead) I found the dial where inserting a screwdriver can turn down the gain. I have done this to the lowest setting and now all the channels have returned, all on 100% signal with the exception of ch23 which is at 80% - I don't know how I had missed this when messing around with it before.

With the loft aerial, my last post was possibly misleading. You were correct originally that I am only missing COM3 on ch40 from this aerial - I guess it is probably best to wait for the power increase to see if this fixes it. It just seems odd that pre-switchover MUX2 was on ch40 at the same power as COM3 and it worked fine.

Thanks again for your advice

I get Freeview from Chesterfield transmitter (Derbyshrie) and its missing off of mine now - may be more of widespread problem?
