Stuttering Oxford TV
 

Hi

For months now my Freeview TV signal on most channels keeps freezing
for a second and then jump on. So I changed my Freeview HD recorder
for a Freeview box.....same thing! I then bought another brand of HD
Freeview box AND SAME THING!!

I know they are mucking about with the Oxford transmitter, so are
others experiencing this. My friendly aerial fitter says not, so how
can anyone explain my problem. All was fine until around late
summer???

Any help welcomed

TIA

Most FreeView boxes give a readout of the signal strength and quality.
What does yours say?

there was a fire on the transmitter that resulted in lower signal quality
until fixed - maybe they haven't yet?

Ask your friendly aerial fitter to come come round with his analyser and
check the BER of each and every mux.

The transmitter went back to full power something like a couple of months
ago, so that won't be the problem now.
As far as I know the only lingering "problems" resulting from that were
problems reported to be caused where people had over-amplified the signal
during the low power period.

Thanks, I've just checked signal strength on most channels and it is
only 50-60% (my mother opposite has 90+%). I had a new aerial fitted
when OnDigital was started, so will get this checked out. However, I
have just put a digital setup on a spur to a bedroom TV and the signal
strength is still 50%ish BUT no stuttering in the last few hours?

Thanks for the replies

How is the signal split to feed the two rooms? Is there an amplifier or just a passive splitter? Can you connect your receiver
direct to the aerial downlead as a test?

I haven't changed my amplifier but the analogue chanels are weaker
than they were and BBC1 Ceefax hasn't worked since the fire.

It is just a passive splitter unfortunately at roof level. The feed to
the lounge TV and any Freeview devices stutters yet it doesn't on the
bedroom spur. I will get the system checked out, but hoped that Oxford
was still playing up after the fire!

Your options would seem to be
Ideally get that passive splitter replaced with 2 output masthead distribution amplifier line-powered from
either of the viewing locations, or
wait until Oct 2011 when the transmitted power levels will rise at DSO.

If the cable run to the bedroom is shorter than to the lounge that alone might explain the discrepancy.

Here is an idea for a DIY bodge that might tide you over till next year.

Put a 2-output amp in the bedroom and run your own cable into the lounge, and use that instead of
the one from the rooftop splitter. Because the amp is situated before the bulk of the cable losses it may well cure the problem.
