Hi,

I have been viewing freeview which was built into my TV. The siganl was not excellent but I received most channels.
Yesterday I brought a freeview recorder and now I am not able to view ITV1, Channel 4 or Channel 5.
Any advice would be greatly appreiciated.

Confused: To be perfectly honest, the reception possibilites on your particular code cannot by any means be classed as good, as there is a mixture of either variable or poor being indicated, the only ones that dont being ArqA / ArqB (Mux Ch34 & 29) from Crystal Palace, albeit still not sparkling!

I would suggest that you reset the recorder to blank out channels stored, then using manual tuning you should try entering Mux Ch22, that being ITV1 from Crystal Palace.

If this procedure captures it then use the "add (or find) channels" to regain any of the others that was previously received.

JB38 - his prediction for crystal palace is a hell of a lot better than mine-I still get
perfect reception on all my tvs. Post DSO- it will be better. (50.9889,-1.4989)

Matt: Well, the difference I see is that out of the six multiplexes presently available from Crystal Palace both confused and yourself only has two of them in the green scale, the remainder under variable, confused's green being Mux Ch's 34 / 29, whereas in your case its Mux Ch's 32 / 34.

There is only two miles of a difference between you both, but with CP being at 67 degrees from confused, whereas its 49 degrees from yourself.

Predictors cannot really cater for local conditions, and so they give an approximation of what's expected.

Mary of London.Difficult to say without a full postcode.First of all,Crystal Palace transmitter all mux's both at present and after DSO2 in April 2012,are within the group A aerial range (chs 21-37).The group W wideband aerial which you stated perched outside on the roof,is no use for Crystal Palace's group A frequency transmissions hence if the antenna itself is a new inferior contract wideband aerial there is a possibility that the lowest frequency you mentioned mux2 on ch22 is not being received at all.Or another possibility is mux2 on ch22 is broadcast on lower power,or a distant (but not far away region wise) relay maybe broadcasting either analogue or digital signals on ch22 causing single frequency interference as such.My best advice is to get rid of the wideband group W aerial,and replace it with a suitable but much superior Yagi 18A group A antenna with satellite grade black (preferred) or brown cable with brass co-ax plug.
