Hi Graham

Yes apologies. the issue is not just 3 radio stations. It affect more radio stations & TV channels. I changed the transponder details to what you stated & see the attached pic re results. What do you mean by tune to 805? regards & thanks

[attachment=69107,1108]

Your manual tune confirms major reception issue with 11552 H.

Easier way to check just Tune to channel 805 which is one of the ones you report as working.

Now display the diagnostics screen which will show the reception figures for the transponder 805 is on. Menu System Diagnostics

London is in zone 1 not 2. You only need a zone 2 dish if you go pretty much as far north as Scotland.

Or are you saying that you have a zone 2 dish?

Hello

Attached are 2 pics of my satellite dish. Its located reasonably close to my HUMAX unit & tv outside & parallel to these via a double glazed window. I took the pics from my window. I could access the dish with a ladder outside once my broken toe heals. What are thinking re access to the dish?

I meant re zone 2 is that I live in the London underground zone 2 for fares. London is divided into 6 zones. Zone 6 being heathrow & zone 1 central London. My post code is SE5 0PW so coverage should be fine.

I heard people saying a software update is required by leaving my HUMAX unit in standby overnight? I always turn off the standby button (pic attached) here nightly but never turn off the mains power at the back of the unit. The diagnostics pic attached states the last update date was 27/7/12? Is this correct?

I entered 805 on the tv & with the attached diagnostic pic like you said graham. Note the strength & quality moves up and down by 10% intervals around every 30 seconds Mostly hovering at quality of 100% & strength at 90% for tuner 1 & tuner 2. Strength did dip to 90% & quality to 80% briefly but then quickly changed upwards.

Also, per the attached pic my current “transponder” states ALL. I assume this default setting of ALL should be like this – let me know.

Would be good to have all radio & TV stations working. If not, if I just got good reception on radio stations 726, 732 & 733 I would be happy.

Let me know your advice. Thanks for all your help to date.

Not sure why you keep using the manual tune options, it’s not needed.

To look at the signal diagnostics for a specific transponder you just have to switch to a channel carried on that transponder. You have already posted that channel 850 works. Simply switch to it by entering 850 on the remote. Now that you are viewing 850 simply bring up the signal diagnostics page. Menu – System – Diagnostics

Having done that for 850 repeat the other list of channels posted.

Best guess so far is that you have water in the coax cabling. Turn off the box and get access to the dish. Pull down the lnb rain screen to expose the f connectors. Unscrew each in turn (11mm spanner).

Inspect the cable ends carefully for corrossion and damp. If you have water you will need to replace the coax cabling.

If you have to change the cabling.

So far you haven’t posted a picture of diagnostics when actually tuned to 805 is on the transponder you are having problems (11426 V) with some of the radio and TV channels it carries. You shouldn’t be even using the manual tune screen, the all refers to what tramnsponders to include in a non freesat channel scan. The screen you need which shows the figures for the currently used transponder is Menu – System Diagnostics. I have attached a photo in the following post

You should easily be able to get 100% quality on both tuners The signal strength may be a bit lower than 100%

How did you get on with the other channels ?

Hi Graham

Thanks for your patience & postings.

Have attached 4 diagnostics reports for working TV channel 805 & for the 3 radio stations with bad receptions 726, 732 & 733. I not phased about the other channels not working posted above as I only want to restore the functionality to my 3 favourite radio stations 726, 732 & 733. Let me know your advice & what to do next please.

I note you suggest there may be water in the coax cabling. By the time I bought all the individual cables etc & hire an engineer to install as I am not technical it might be easier in the long run to by a new satellite dish for £99.99?

Let me your know your thoughts & again thanks for all your advice. Regards

I asked you you to check the other channels because if they are affected it would help to confirm that the issue is likely to be water. Check the connections at the box end as with some types of coax they can act as micro water pipes and introduce water into your box. This of course is likely to totally ruin it.
