The symbol shows the location of the Winter Hill (Bolton, England) transmitter which serves 2,690,000 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 Winter Hill (Bolton, England) mast?

Karen, Heart TV is on a very low with a directional , beamed from in the direction of . Most people can't get it at all. Tiny differences in the sensitivity of TVs will give the effects you are getting. Assuming that you have no loose cables etc, the only solution is a better aerial. As it is not known how long this service will last and assuming on all the other is OK, you may not want to take that option.

Keith Hill: Manual tuning or pulling the out for the part of the where the Welsh are, although this might be tricky due to Moel-y-Parc (the in which you are likely picking up) and .

The other possibility is to an attenuator, assuming that the wanted from Winter Hill is higher than that of the unwanted of Moel-y-Parc. This will reduce the signal levels with the that the unwanted ones are disregarded by your , or at least not given primary positions.

Some receivers, usually the HD ones, have a setting for or preference which would achieve the same objective.

Does anyone know why the Arqiva T2 multiplexes have a different bitrate to that of BBC B?

com 7: 40,200,039 bps
com 8: 40,200,034 bps
BBC B: 40,214,669 bps

(bps = bits per second)

The bitrates were measured from recorded samples of the full transport stream by "DVB-T2 Data-Rate Calculator", which is a free tool found here:

DVB-T2 Data-Rate Calculator - decontis

To give an idea of the accuracy of the measured bitrates, here are the results for all the multiplexes.

40214625 bps BBC B

40200015 bps com 7
40200018 bps com 8

27144380 bps Arqiva A
27144382 bps Arqiva B
27144372 bps SDN

24128332 bps BBC A
24128338 bps D3&4

18096298 bps LocalMux1

9048132 bps LocalMux2

The results from "DVB-T2 Data-Rate Calculator" are identical to those from my own program, which works like this:

TS packets are read until a packet containing a PCR is found. The PID is noted and PCRs are read from packets with this PID, noting the corresponding packet count, until end of file.

Results from a ten second (long enough to capture all the service tables) sample of com 7 were

pcr pid = 401
first_pcr = 2138813251731
first_packet = 2
last_pcr = 2139084457513
last_packet = 268483

Using this data we get:

bitrate = 27000000*(last_packet-first_packet)*188*8/(last_pcr-first_pcr) = 40200015 bps

Notes:
A Transport Stream (TS) is a sequence of packets.
A TS packet is 188 bytes long or 188*8 bits.
PID = packet identifier = A unique integer value used to identify elementary streams in a Transport Stream.
PCR = Program Clock Reference = A time stamp in the Transport Stream from which decoder timing is derived.
PCR is a count of cycles of the 27 MHz system clock.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
