Thank you Dave - I manually tunes, so know I am on , as I ensured to use its MUX numbers, I try 30, and it say 100% Strength 0%, if I try searching, they are ALL saying "nothing transmitting" or words to that effect.

I have a (it splits to 5 TVs in the house this way), however thinking that may be the contributor, I disconnected the , and put it directly into the Topfield (I use that the most to be honest), and same problem. I even powered off the Topfield, retried and same problem

Does transmit the Mux3? If so, I'll manually try *its* channel number - any ideas where I might find that?

thanks

I just found 's page, Wooburn digital TV transmitter | ukfree.tv - independent free digital TV advice and it says 52 for Mux3, and that tells me 69% , 0%

Checking Wooburn's Mux2 channel 56, I get 70% power, 37% quality, Mux1 channel 48, I get 77% power, 86% quality.

All the other Mux channel numbers are 100% power and 100% quality

thanks

Mind you, checking my postcode against ukfree.tv site, it reckons I should be getting from :)

Checked its 40, and 29% 0%

So it definitely isn't finding that one!

Reason I tuned manually was because I was finding other transmitters, with poorer signals, and having multiple versions of each programme channel.

Dave Lindsay: Thank you for your response. Presumably the for the recorder must come from the same place as the tv, as the is plugged into the recorder and out to the tv. I have a Sony SVR-HDT500 + HD Recorder. How would I find which it is tuned to?

Richard: If your is finding other , and those channels fall outside of the range used by , then you can avoid them by using the unplugging aerial trick I mentioned.

If there are other transmitters that are within the "target" of say 21 to 30 for Crystal Palace (I allow a few channels either side to ensure that they're all picked up), then you may have to revise your plan.

I don't have first hand experience of these Humax devices. However, I have read that when tuning some HD tuners you need to select the HD when tuning in the HD channel, that probably being "DVB-T2" as opposed to "DVB-T" which is for definition.

I wonder, if you are doing it manually if you have to set the mode manually and that it does not automatically assume the correct mode. This would perhaps explain why it does find a , but just no .

Kate: Sorry to hear of your continuing trouble.
When you ran set up for your TV did you select as the source? If so, and your card now can't find any thing it is probably that the software is not looking for the in their new frequencies. Try selecting "Any source" or "All" when scanning.
