Pip: The Digital UK postcode checker predicts that you should currently be able to receive at least four muxes from Dover (aerial set for horizontal polarisation and pointing at 105 degrees, slightly clockwise from E). After switchover the best prediction is for Heathfield with good reception shown for your postcode area on all six muxes after 13th June 2012. Aerials for Heathfield should point SW at 234 degrees and set for horizontal polarisation. Reception from Dover after 27th June 2012 shows a slight deterioration for Mux ArqA. Remember that predicted reception is subject to there being no local obstructions such as trees or tall buildings blocking the signal path.

Superkool: It is possible that the dish was connected to a Sky box, a UHF tv aerial was connected to the RF in of the Sky box and the RF out of the Sky box was fed to the slx8 for distribution to the aerial points. You really need to find out what the dish is connected to (if anything!) and also find out if there is a UHF aerial in place. The Freesat box will only work with a dish connected directly to its input, and since there is likely to be no internal RF modulator you will have to view the output via a scart lead connected to your chosen tv. Connecting a UHF TV aerial directly to the UHF input of the slx8 will then provide a Freeview signal at each of the aerial points.

lynny: Are you connecting the new tv to a UHF tv aerial? It will not work with a satellite dish as the tuner for freeview works on a completely different set of frequencies to that used with Sky and Freesat.

Charles Stuart: Both C52 and C48 are 8k mode and are transmitted at 170kW. That just leaves MuxA/SDN on C31 still using 2k mode at 20kW.

ringo: Details of your postcode, so that a check on predicted reception can be made, also details of your aerial/transmitter would be useful in order to give more specific advice. Basically Chelmsford is served by Crystal Palace and Sudbury. For Crystal Palace check for single frequency interference around C29, for Sudbury C63. It should be noted that C63 from Sudbury is on abnormally low power for a main station and is this causing problems for many viewers. You could try clearing the channel list and then doing a manual tune on the frequencies for your chosen transmitter if your receiver has a manual tune option.

Bill: As a matter of interest try doing a factory reset, then scan with the aerial unplugged, after which do a manual tune on C59, so that should be the only set of channels stored. Retention or loss of the stored channels would show up whether it is a memory capacity problem or something associated with the errant mux or C59 perhaps.

barry beales: No, but you are supposed to be able to receive it from either Belmont or Waltham, using a suitable aerial. Historically the Kings Lynn transmitter was provided when Belmont, which used to provide Anglia TV to the area was switched to Yorkshire TV leaving viewers with incorrect local news. It provided BBC1 East and Anglia TV only, with viewers using Belmont or Waltham for BBC2, C4 and C5. At switchover therefore, only the 3 PSB muxes were provided from Kings Lynn.

barry beales: I should have added that viewers who have two aerials diplexed together will find that due to the spread of frequencies now used at both Waltham and Belmont they are likely to find some muxes are missing. Belmont + Kings Lynn leaves out ArqA and ArqB from Belmont. Waltham + Kings Lynn leaves out SDN from Waltham.

cuil: Unfortunately the Digital UK postcode checker predicts that you are only able to receive signals from the Perth relay transmitter, which only carries the three PSB muxes. The owners of the COM muxes declined to extend coverage to further sites when the switchover was implemented. Currently reception of the COM muxes is therefore only available in your area to viewers able to receive signals direct from Angus.

emma: If your box is tuned to the Cirencester relay transmitter the frequency for Mux D3+4 changed from C30 to C29 in September 2011. As a result you would need to do a factory reset to clear the channel list and erase all memory of the old frequency before the box would realise that the new C29 frequency is required to be tuned in. If on the other hand you are using Mendip (aerial points SW) or Oxford (aerial points E) the box could be tuned in to the wrong transmitter as Mendip (C54) is found second in the scan and Oxford (C60-) third. Check in the channel list for a duplicate ITV1 that works, this is usually to be found in the 800s if there is one. Also check for single frequency interference on the required frequency if there are no versions of ITV1 etc found after doing a reset/ scan for channels.
