John: For regular reception in the UK of German TV channels you need a generic satellite receiver with the dish set on Astra 19.2E. If your query refered to reception on Freeview equipment via a normal TV aerial, the answer is normally NO, however over the past few days German TV and FM radio signals have been received in a number of locations due to the inversion effect.

Hi, I am a resident of the St.Johns Wood Area and have a communal aerial in my building.All other households(As checked with the House Manager)have a good aerial reception,but my TV with a BT Youview box is receiving only 24 Freeview channels and that too with bad reception(20 - 45%).Have tried changing the coaxial twice but to no avail.Will a Booster Help?? Please advise.If yes which one?
Many Thanks..

Aman: As you are using a communal aerial system then your hands are somewhat tied as far as to what you can actually do is concerned, as these BT YouView boxes are in reality Humax DTR1000's and as such top of the range devices.
If you are on friendly terms with any of the other residents in the block is it not possible for you to try your box out on their aerial connection? and carrying out a retune whilst connected, as you do not require the phone line to be connected into the box as it should work perfectly OK without it, as other than that I cant see much that you can do except to try another Freeview TV out on your aerial connection, this for the purpose of eliminating the possibility that your box might be faulty plus at the same time verifying (or not!) that the signal being received is sub standard.

The modulation does not affect the propagation conditions, but different methods of modulation will cope differently with the conditions.

I get channel 49 on my newer tv, but with my 15 yr old
magnavox it won't come in. Antenna works OK on both.

It's not the different modulation but the different compression and encryption methods together with error correction algorithms that makes the difference. With 'old' analogue TV, vision had AM and sound was FM with no attempt at compression, etc. That, as we all should know, suffered from co-channel as well as adjacent channel problems together with the effects of tropospheric lift giving unexpectedly long transmission distances.
With digital signals, there are several modulation methods but the more recent systems use 64QAM or even 128QAM. The digitised signals are also compressed and have error correction codes inserted. And they still suffer from the effects of co-channel and adjacent channel, but usually to a lesser extent for adjacent, 3rd and 5th channel separations. It is because of these different formats, though they are still a form of 'FM', that digital signals tend to fare better when interference is around - but correction can suddenly fail to sort out the incoming wanted and unwanted signals and all the affected ones become undecodable, as has been reported by many on these pages.

The very idea of chopping up each cycle into chunks is clearly a form of witchcraft anyway!

gerald: What kind of box is attached to the old TV? Cheap digiboxs (like my Goodmans :-)) scan from low channels numbers upwards - so it might not pick up a higher channel. Dave Lindsay normally advises people to pull out the aerial lead for the first part of the scan. BTW - its nivce to know there is an international audience here!

Hi, I have two sky hd boxs which give the no signal message and number 25 on all the sky channels (all the others work fine) whenever the weather is very hot. The strange thing is that it happens at the same time 12 noon until 4pm every day. If the weather is our usual mix of sunshine and showers there is no problem with the signal. Can anyone suggest anything?
