Dave Lindsay: Yes, I am sure that the trees will most likely be causing a problem as indeed they can do if roughly in line with any signal path, but with regards to the actual height of the aerial being a contributory factor to the problem, I feel that any improvement to the situation is much more likely to be achieved by repositioning of the aerial rather than increasing its height, as the philosophy of "the higher the better" is something that exclusively applies to an aerial used for transmission purposes and not one used for reception when in a problem area, as in many cases the reverse is frequently found to apply by in some cases being able to take advantage of a "stable" reflection.
It will be interesting to find out the result of Kaz's tests, as I likewise suspected that Ch44 is maybe just lagging slightly behind the other muxes at a level not quite good enough to resolve a picture, although the manual tune "without scanning" would instantly reveal if that is the case or not, as if it is and the signal is seen to be of a reasonably stable nature then dependant on exactly what level its sitting at its possible that by giving the signal a mild boost it may lift it enough to enable a picture to be received, albeit this normally being an alien action when a 20Kw transmitter is located at only 12 miles away.

Jack: On checking your reception possibilities you are quite correct insomuch that as far as "reliable" reception is concerned it will only be possible from the Newhaven PSB transmitter which offers a limited number of channels
However as you presently have a Sky+ set up I would not hesitate in recommending that you go along the Freesat line, as if you purchase a Freesat HD twin tuner recording device (PVR) that would take full advantage of the twin inputs you have from the dish.

Jack: This is a link for the type of device referred to, other cheaper types are available but up to a point you get what you pay for, and the device in the link is one of quality.

tony: No sound on what? are you meaning when on Freeview or Sky whilst on the second set? although without knowledge of your location (post code or one from nearby - a shop etc) and so unable to check, but if the sound disappeared at the same time as you set the RF output channel on the Sky box just try selecting another channel and rescan the second TV whilst its set on analogue to enable the RF2's new output channel to be found.
Apart from that I take it you are using a magic eye? by the fact of you having mentioned that you turned the RF2 power on, as if you don't have an eye then the power should be left off.

James: If the TV sound is also distorted whilst on Freeview then that most likely a fault within the TV, however if you are meaning that its only distorted whilst viewing Sky via the RF link then for a test try unplugging the normal aerial thats going into the Sky boxes aerial socket and have a check at the result, as it could be that the local Fenton transmitters digital signal is slightly too powerful and is causing a problem within the Sky boxes RF analogue modulator.
Further advice given dependant on the result of the test.

Mike: If your Sky+ box is of an HD type (as both SD & HD types exist) then you can couple it into the TV via an HDMI lead, although are you also intending to use the Freeview HD facilities on the Samsung TV? as if you are then a normal aerial will be required as the LNB's spare output ports are only of use if the TV is also Freesat capable, as indeed many are.

ems: If any changeover has taken place at the station you are receiving from then you should always carry out a rescan as a matter of course, this preferably being done after having carried out a factory reset.
Any further difficulties will require a post code to be provided, or at least one from nearby like a shop etc, as this enables the signal levels expected at your location to be checked upon.

Tony C: Advice can only be given on queries of this sort with knowledge of your location, this being in the form of a post code or one from nearby (e.g: a shop) as that will then enable the signals levels expected at wherever you are to be assessed, as what you mention could indicate that you are possibly located close to a main station and suffering from an excessively high signal level which is blocking reception.

Jean: Apart from you possibly living in an area where reception is a bit iffy whereby signals can occasionally drop out, but when you first auto-tuned the TV to pick up the Freeview channels did you select "store" before reverting to viewing? as although most sets automatically store them some don't.
With regards to the signal levels expected at wherever you might be located a post code is required to be able to assess this, although a post code from somewhere "nearby" such as a shop would suffice.

Dave Lindsay / Kaz: I wasn't quite so much suggesting that Kaz's mothers aerial was pointing at Bexhill, but more the case that the picking up of any channel from it at all could suggest that the aerial in question which is supposedly facing Heathfield? was possibly out of alignment for picking up the latter, as something has to be wrong when Ch44 from Heathfields 20Kw transmitter located 12 miles away is not being picked up when Ch40 from Bexhills 400 watt transmitter @ 9 miles away is, especially when both stations are transmitting on the same horizontal polarity which generally gives a more positive null point at right angles to an incoming signal, the null point (or not too far off being) referred to should be facing towards Bexhill if the aerial was properly aligned for Heathfield.
