Rob: In addition to that said by StevensOnln1 / Richard Cooper. It has to be assumed that the area you reside in is only covered by a Freeview "light" transmitter? as otherwise you would be able to view the two programmes mentioned on a normal TV, movies4men (epg 48) being transmitted on COM5, and with Spike (epg 31) broadcast on COM6.

Brian Springthorpe: Reception in many parts of the UK is presently being affected by a series of high pressure zones sweeping across the country, the effects of said pressure being most likely reason for the reception problems referred to, unfortunately nothing can be done to help rectify the problem except to wait until the situation improves.

Mike Stevens : As you have stated that reside on a houseboat, then you have to take into account whether or not its subject to slight drift in relation to where its moored, because if it is? then a Yagi 18 is not the best choice of aerial, as these high gain aerials are only that (high gain) because the aerials series of director elements effectively focus the signal on the active element of the aerial. Needless to say, any slight drift (or variation) in the boats position is likely to result in a significant drop in signal level, something which could result in intermittent picture glitching.
You would be much safer using a Log periodic aerial (e.g: Log 36) with, if necessary, a variable booster.

Rob: That said in my own reply was based purely on the possibility that you were unable to receive either of the two channels in question because of your location, (Freeview light area) and as such were rather annoyed to find out that a streaming option of either programme was not offered, even although you might well have the facilities necessary to do so.

Peter Dennis: Yes, it certainly was an error, and one which was even made by / www.terrestrialtv.uk. / as they also had BBC4HD (106) listed as moving to COM8, this having now been corrected to COM7.

Brian Springthorpe: When you say that neither of your two other TV's show the same problem as your "main" lounge TV is experiencing, is that when they are tuned to the same channel as your Panasonic?
However, irrespective of whether they are or not I wouldn't advise altering anything at this present time, as many parts of the UK (particularly Wales / South Western area's) are experiencing intermittent problems with reception due to the effects of high pressure zones sweeping across the UK, said effects being the enabling of reception from distant transmitters (not necessarily UK based) which operate on the same channels to that used by the local station and clashing with same, some channels being affected much more than others dependant on the frequencies / channel numbers used by the local station.
This situation is unfortunately forecast as remaining until well into next week, albeit that its seen to clear for a short time late Wednesday / Thursday before returning with a vengeance for the following few days.

Eric Brett: Purely out of curiosity, it would be of interest to know the brand & model number of the combi- receiver referred to?

John H: Your location is indicated as being able to have excellent reception from the Rowridge transmitter @ 13 miles / 169 degrees, (horizontal polarity only) albeit that the terrain indicator shows the signal running close to ground level from approximately 0.5 miles prior to your location, something which can sometimes result in slight picture glitching problems dependant on what's on the surface of said ground, e.g: trees etc.
If your equipment is capable of receiving DVB-T2 transmissions?, i.e: able to receive BBCHD 101, if yes?, then go into your TV (or boxes) tuning menu / selecting "manual" tune followed by entering C31 (COM7) but "not" followed by search or scan, as this mode has the effect of causing your tuner to act like a form of signal meter, indicating the slightest traces of any signal being received no matter how low it might be, which of course according to that seen, should not apply in your area.
That said, a quick rooftop search did reveal an aerial facing towards the Hannington transmitter @ 31 miles / 13 degrees, COM7 from Hannington being on C32.

John H: Re your Samsung 24E390, according to my info this model is indeed fitted with a DVB-T2 tuner, as of course it would have to be otherwise BBC1 HD (101) would not be receivable.
However, on the subject of reception from COM7 / COM8. Although signals from lower powered transmitters are more susceptible to partial blocking etc by such as dense trees etc, and so if the loft aerial referred to have been self-install, reception of these two muxes "might" possibly be improved by either, (1) : trying a test by turning the aerial a few degrees to the left or right, or if no improvement is evident, (2) : physically moving the aerial a little to the left or right (or even up or down) of its present mounting position, as in areas such as yours its frequently found that aligning / positioning an aerial for peak performance on one multiplex does not necessarily hold for another, and so they have to be averaged / balanced out for satisfactory reception across all multiplexes received, but though with an obvious bias towards reception of the weakest signal.
This being where the aforementioned "manual tune" test comes into the equation, as said adjustments could be made / tested out / whilst the TV is left sitting on the signal test screen.

Andrew: Channel 38 can be used virtually anywhere in the UK for the analogue RF output on Sky boxes.
