Full Freeview on the Oxford (Oxfordshire, England) transmitter
 | Google Streetview |  | Google map |  | Bing map |  | Google Earth |  | 51.790,-1.179 or 51°47'25"N 1°10'46"W |  | OX3 9SS |
The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 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 Oxford (Oxfordshire, England) mast?

Hi again,
will try the neighbors first, but could be tetra then as the interference only affects the channels 60 programmes then?
lets hope its the neighbors!
thanks again

As moving the tv or changing lead length makes so much difference and as you are relatively close to the transmitter, don't rule out the possibility that there is a break in the coax lead from the aerial to the set. The signal you are getting may be just the coax acting as the aerial, thus giving differences in signal strength as you change coax length and position. A break will also give you different effects on each frequency as it will not be a 75 Ohm match
It is very easy to test with a multimeter. At the aerial end, join the inner and outer of the coax and then at the set end use a multimeter (or even a battery and torch bulb) to check for continuity between the inner and outer of the coax.
I have seen this before and the lack of a shield on the wire (in effect) also produces resonance at strange frequencies. Check continuity also at your spurs to other sets as a break in their coax will act as another input on a different (interfering) frequency.

If it was a break in the coax would i not be getting the interference on all the channels? I am only experiencing issues off channel 60 mux. No other channels are an issue not one.
really find this frequency stuff confusing, thanks for all the help.

Were any taxis operating in the vicinity? Or police vehicles? Both used to upset my TV reception if they used their radios nearby.

I live near Thames valley headquarters in kidlington and near the police station too. However never been an issue before and lived here 12 years now.

Rob.

A break in the coax means you have an unterminated length of wire that is resonant at a frequency that is set by its length and the velocity factor of the wire. This can enhance or nullify signals at one frequency. Worth a check as it is simple to do.

Hi All,
Could this be the problem, strange how there are now works on the mast. Does anyone know the detail of the works, are they relating to channel 60 issues?
Regards
Rob

Right, neighbors are yet to get back to me on anything the other side of the wall. I have borrowed a SLX dvb-t signal meter, lights up 80 top figure on the device, after the splitter 60 at socket down stairs. 50 at back of tv, still the same issue with everything on channel 60 having intermittent blocky picture and sound clipping, not all the time just hiccups at random times but can be every 20 seconds or wait 2-3 mins and starts again.
again thanks for the help all.

Well hi all again, my neighbors still have not got back to me so tried a borrowed set top box and placed it on top of my hard drive recorder and not a blip all night, could this still mean its interference on the Sony tv or is the tuner on the blink?
again any advice would be appreciated.
Regards
Rob
