The symbol shows the location of the Mendip (Somerset, England) transmitter which serves 720,000 homes. 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?

As there seems to be spate of aerial distribution amplifiers failing, I would suggest that, if
possible, a passive splitter is tried first. If there is sufficient signal strength, there will my no problems, and nothing to fail. My own setup is configured as follows: aerial to splitter, one side
of which feeds a Panasonic TV, the other side feeding a Panasonic DVD recorder/PVR, the RF output of which feeds a Humax PVR. The signal strength /signal quality bar graph on the
TV and Panasonic PVR shows 100% for both values; the figures on the Humax PVR
shows 79-81% signal strength and 100% for quality.

Jeff Glynn: Yes, passive types might be OK in areas where as you have said, a sufficiently high signal strength exists to be able to use them successfully, but unfortunately that doesn't apply to most areas that suffers from reception problems, plus!! you are using a combination of equipment fitted with top class tuners, as Panasonic and Humax tuners are about the best around, as the types fitted in most other brands are simply not up to their standard in sensitivity nor stability.

Humax of course being about the most accurate for its signal strength readings, whereas Panasonic is inclined to err slightly on the exaggerated side of reality.

Hi guys,
we cannot receive any BBC freeview channels at our house. We have 3 different freeview boxes. We have retuned them and still no BBC.
Can anyone tell me if there are problems in my area in Bristol?
How do I get BBC back on the freeview boxes?

nige burr: Unless you are located in some horrendous localised black spot for reception then as the Kings Weston transmitter is located at only 1.8 miles away from you its possible for you to be receiving an excessively high level of signal dependant on the aerial system being used, as this can completely block reception by overloading the tuner.

If you are using any form of amplifier then for a test try by-passing it, or alternatively use a piece of wire (about 2 or 3 feet) connected into your equipments aerial socket and carry out a "manual" scan on mux Ch43 (Kings Weston BBC1), if though your equipment does not offer a manual scan option then carry out an auto-tune "after" having blanked out anything stored by auto tuning with the aerial removed.

By the way "if" you are receiving from Mendip then the BBC channel is mux Ch61
