Can someone explain ? I live in Insch [AB52 6NF]. I have two Humax PVRs [HDR-1800T 320GB Freeview].
An outside aerial, tuned to Durris, feeds both systems.
Two days ago I did an Automatic Search on one Humax and there were 18 TV and 1 Radio channels now downloaded that I did not have previously. I did an Automatic Search on the other Humax but only one new channel was downloaded [BBC 4 HD]. On looking online I found that all the new channels on the first Humax were listed in Multiplex COM7 HD. I also found that Durris transmits COM7 HD channels but Gartly [some 3 miles away from me] does not. Can it be that, although using the same aerial,[tuned to Durris] the second Humax is [somehow?] picking up its signal from Gartly and not from Durris ?
I would dearly like to hear from you about this puzzle. 01464 821228. David Stewart

David Stewart: Firstly, never put your phone number, etc on a public site (hopefully, Brianist is watching) - nobody is ever going to contact you privately, etc, so for securities sake, all we need is a postcode for location.
Your probably right that one Humax is picking up a different transmitter. If one is getting Com7 and the other isn't, and they both have HD tuners, then either something is wrong with the connection to the aerial of one of the boxes, or its picking up a transmitter without Com 7.
Easiest way to cure that is to find out what channels both the 'good' and 'not good' transmitter are broadcasting on. The 1800T will do an auto search only, and its often the case it will find the lowest channel number (and hence wrong transmitter) first. So the trick is to pull out the aerial lead for part of its scan, and then put it back in so it catches the one you want. About a third of the way through the scan used to work for my digibox, but its a bit hit and miss, and often a couple of tries,

David Stewart: I feel that the 18 new channels picked up by "one" of your Humax's was purely due to reception conditions happening to be favourable at the time you carried out the scan, although you would have received BBC4HD whether it was or not, as this programme channel has been "temporarily" moved onto the PSB3 HD transmitter for the duration of the Olympic games, the purpose of being to enable the maximum number of viewers to follow to said games in HD.
The reason why I referred to "favourable reception conditions" is that the signal from the Durris transmitter is seen to suffer from four line-of-sight obstructions prior to reaching your area starting from just under 8 miles out, the most sizeable of the four being two miles long, said obstructions being the reason why reception in your area is only listed as being good on the three main PSB channels (BBC /ITV/ HD service), the COM's (SDN/ ArqA / ArqB) being in the category of "poor", with COM7/8 officially considered as not being receivable in your area.
However as far as your Humax's are concerned, are both fed via a two way powered splitter? and have you tried swapping their positions over followed by carrying out another auto-scan?. Another point being, have you checked that the powered aerial facility (via installation menu) is turned off on both machines?
Further advice as required.

We have just built a new Hotel on Straik Road, Westhill, Aberdeen on the site directly behind the BP petrol station. After erecting the 4 storey hotel, some of the residents have informed us they can no longer receive a free-view signal - if there any advice we can give them on how best to resort a suitable TV connection? Or is there someone who can visit them to re-tune them to another transmitter? I look forward to your response.

Alistair Broadley: If the residents in question are those in the bungalows located on the North side of Straik Road? then there isn't really an easy fix to this problem, as its one which can occasionally occur when a new build of a taller nature happens to be located directly in the line-of-sight of the signal path from a transmitter, the situation being somewhat worse the closer the receiving aerial's are to said obstruction.
On the subject of possibly tuning to an alternative station, there isn't any!, as Durris @11 miles / 198 degrees is the only transmitter that covers the area, a reception predictor check based on the post code of the BP garage indicating first class reception from same in that area, no (or very few) rooftop aerials being seen via a Google earth rooftop check of the properties allegedly affected by the obstruction, inclined to suggest that indoor aerials are possibly being used.
The best policy would be to have an aerial installer visit the properties in question and make an assessment of the situation, as signal tests have to be carried out to determine if the problem can be rectified by simply moving the aerials to a slightly different position to where they are presently sited.

Alistair Broadley:
Following on from that said by jb38, the only other alternative, if the aerial cannot be repositioned, is to consider Freesat - providing the new hotel structure does not obstruct the view of the satellites. As a very rough guide, check to see if the hotel is anywhere near a line of 28 degrees east. If it is then there may even be problems getting Freesat and Sky. If it is not then it may be worth one resident trying to get Freesat. Sky would be an expensive alternative as it is a subscription service.

Here we are nearly into a new year 2017 and though free view says we can view a new channel on 74 if we retune if needed I have done so 3 times on 4 TVs I then look and find none have found channel 74. I note also some channels have gone especially the +1 hour channels after I had retuned yet they worked fine before my retuning and some are still showing up on sky though since sky gave me a modern box I have noticed although some channels on sky are missing too or ones my old set let me view are no longer viewable unless I pay or are missing very strange but now I know why my old box which was an original box has been taken away by sky not left for me to dispose of or use if I wanted to. But why is it free view channels are missing and why is it some areas don't get some channels yet others do? We all should be able to view all channels they broadcast where ever we live, the fact we have pixeled images in poor weather or poor recover areas so long after going fully digital is not good either we were told we would get better picture quality along with more channels etc so why is it that there are areas where they get little or no reception and why is it relays don't show all channels either????
This is poor service in a digital era so long after changing over they still have not sorted it all out and some channels we should be getting some still are not recieving they need to get this sorted and quick too!!!!

Anne Burgoyne: If your on Sky, then sort it out with Sky - Ch74 is on Freeview! And since we have no idea of your position, we have no idea as to what your signal should be like. However, if your continually getting a rubbish signal, that points your own system etc being a problem.
