The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Mendip (Somerset, England) mast?

Thanks for the advice, Mike.

This is weird but as suddenly as it started 2 and a bit weeks ago, last night I had no problems with any terrestrial channels. The only variable was rhat last night was warmer.

This morning, so far so good.

Thanks once again

I'm finding aspects of the revamped site rather difficult to use. The biggest single problem is the "My Freeview" setting page. The site asked me to share my location, which I duly did. However, it didn't work correctly, placing my location in Calne, which I think is about thirty miles by road from my actual location in Bristol. There doesn't seem to be a means to reset it, so I'm stuck with inaccurate information and to view the Mendip page, I have to go through the Transmitters page.

I wanted to look at the Mendip page to see which MUX the Horror Channel is using. It's a good addition to Freeview, having several programmes that I enjoy.

Charles Stuart: Purely on the subject of the Horror Channel / LCN70, this is transmitted on Mendip's COM6 / 722.0Mhz, if 70 isnt seen on the EPG list then a retune is required to update the listings.

As far as your location problem is concerned, the post code you entered "is" for Calne, the location being close to the Oxford Road / Wood street mini roundabout, the Calne Freeview light / PSB only "relay" transmitter (no COM4/5/6 etc) which is listed as covering that particular area, located at 0.5mls from the post code location.

Charles Stuart: I just noticed on one of your earlier postings made back in January, that BS15 is listed as the post code area, whereas the latest is SN11, so there has to be an error somewhere along the line.

This time I didn't enter a postcode. It simply asked me to share my location, which I did. How do I revert to a manual postcode input?

Charles Stuart: Although, just like yourself, I preferred the previous system rather than this updated one, however the easiest way I found is to click on the "cog wheel" seen on the extreme right hand side of the red header bar at the top of the postings, this will open another screen where you can enter your post code, once entered click on "predict" and that will (or should) have changed your location.

You can check if it has without even typing out another posting, as your new location should be included in the information under "Your comment please".

jb38, thanks for the suggestion but it doesn't seem to work. No new screen appears. Perhaps Briantist could set up a nice easy system to change one's location. After all, this site will be really useful when moving house.

Charles Stuart: Well, Briantist really is the best person to advise on this, as he designed the whole system, but though when you say that No new screen appears, I omitted to mention that the one that allows you to enter your post code will "not" appear if a post code is already stored, which in your case should apply albeit with the incorrect code, the point being that you have to click "clear" to the right hand side of the code that is showing before the one I referred will appear.

Of course it all depends on what system you are using, as I noticed others also experiencing problems since the update, I use Win7 Pro with the browser being Mozilla FF36, but I also tried the same test on an older Win XP Pro PC that I keep a load of technical files stored in and the results were exactly the same as on Win7.

Thanks for telling me about "clear". (I use Firefox for Mac and it seems the same as Windows.) I now have a new problem. Instead of getting a map, I get this error message:
Warning: file_get_contents(class_googlemaps.js): failed to open stream: No such file or directory in /home/admintv/public_html/class_googlemaps.php on line 308

Charles Stuart: I also experienced that very same problem, but I managed to get over it by clicking on "terrain plot" seen in the middle of the three choices (mapping - terrain plot - full details) this then allowing the newly entered post code to appear.
