Lesley Kokai: In addition to that said by MikeP, which by the way is perfectly correct, purely for information purposes, PTC Punjabi TV can be viewed on Sky TV (satellite) as a free-to-view channel on guide number 822.

MikeP: Yes, fully agree, as that could well be the case, although that said was based on that seen on a google earth rooftop check of the area, and where most of the aerials (with the exception of one) are seen to be pointing in an Easterly direction, the angles of suggesting that Waltham (@ 29 miles/136 degrees) is the preferred station, albeit that a line-of-sight obstruction to the signal path from said station is seen at approximately just under 4 miles from Dave's location.
However, the advice given with regards to the best RF channel to use is really irrespective of where Dave receives his Freeview signal from, at least from within the 4 possible sources, as RF38 does not clash with any of them.

Charles Davison: Just a small point concerning Sandy Heaths COM TX powers.
According to digital UK, COM4/5/6 are all running at 170Kw, COM7 - 49.596Kw and COM8 - 49.14Kw.
Maddingly's local mux (L-CAM) is low powered at 1Kw.

Briantist: Just wondered if any info has been released as yet, with regards to the radiation pattern of the new Madingley Mux?, as I was unable to find any info on it in this respect.

des sykes: Its still on guide number 24, but though is now being transmitted on the PSB2 Mux as used by ITV etc, therefore you will have to carry out a retune in order to update your programme guide.

Syd Wall: The change made to ITV4 only involved the Multiplex transmitter number that the programme is broadcast on and "not" the programme guide number (EPG) used to receive it, ITV4 having previously been transmitted by the COM6 Mux whereas now its on PSB2 as used by ITV1 etc, this now enabling viewers who reside in Freeview "lite" areas to receive it, whereas they were unable to prior to the change.
As far as programmes scheduled for recording are concerned, the situation will not have changed, as when you set whatever to record, the data stored involves the Mux channel number associated with the programme, when you retune the receiver this action automatically deletes this info no matter what brand of device you happen to be using.

John Penry: The viewing card cannot cause this type of problem. If though by any chance you are connected into a communal dish system such as used in apartment blocks etc, then the problem is liable to be caused by an interruption to the mains power supply feeding the distribution amplifier, however, should the system referred to not be applicable, then the problem could possibly be caused by a defect in your Sky boxes power supply, something not exactly unheard of.
If this problem occurs on a regular basis, then you should try disconnecting the box from the mains around 5pm to allow it to cool down before powering it up again about 5.45pm or so and see if anything happens around 6pm, if not, then this is inclined to indicate that the internal power unit is defective, the defect referred to being caused by temperature related component failure, electrolytic capacitors being the component in question, boxes that suffer from this type of problem usually running for days before the problem re-appears.
The only thing I did wonder about being, are you TV's fed from the Sky boxes RF2 output? or I.O port modulator if the box is not fitted with an RF2 socket?
Further info / advice dependent on feedback.

Anne Robinson: If your Sky reception is via a normal dish and which is your own property, then the problem could be caused by the dish having moved slightly out of alignment, this if more than a few degrees always usually resulting in a "no signal" message.
If you are using a normal Sky box? try disconnecting it from the mains for a few minutes before powering it up again, as this procedure can resolve all sorts of box problems, "not" the dish though!

Bill Evans: But did you also retune the Humax? as all Freeview devices have to be retuned.

Dave: Aerials in your area are seen to be pointing in a number of directions, therefore it would have been of assistance to know which station you are receiving Freeview from, however as Belmont or Waltham would appear to be the favourites you should try setting the RF modulators output to 38.
That said, it should also be noted that if you are using an aerial amplifier? then this will (or is liable) to add grain to an analogue picture no matter what channel the modulator is set to, especially so if the amp in question is a of the high gain variety.
Another possible source of trouble being if there are any 4G transmitters operating in the area, in that case, the addition of a 4G filter in line with the boxes RF input would most likely cure the problem, although 4G filters should really be fitted between the aerial and the amplifier.
