Which companies have run the Channel 3 services in the Sudbury transmitter area
Well the predictors give C37 COM6/ArqB predicted reception to be better than SDN or ArqA right across your postcode even though reception of all can change across the postcode, lower numbers doing slightly better. Very odd.
So why C37 usually goes first is a slight mystery. Not easy to find all transmitters that use C37.
(BTW C39 used by Tacolneston).
The date is above the post or block of posts if several on the same day!

Thank you for that info.
You say certain channels are KNOWN to be better than others. I wonder why they are not all the same. I can understand that on the higher frequencies there my be trouble, but we no longer have channel 60 which was always difficult.
We now, nationally, use a very few channels and in a tight group. How did they manage this and why did they not do it in the first place? We had to buy new aerials. We could have kept our old group B

Hi. I( suspect you are misreading/reading the wrong thing in what I said. According to the Freeview checker, your predicted reception of COM6 is better than COMs 4 & 5 which is why it's a bit surprising that you experience COM6 on C37 getting disrupted first.
Reception will vary across the postcode because of the changes in local(ish) terrain and it seems lower street numbers in your postcode fair slightly better according to the predictions!
No doubt the frequency planners will have had a bit of a nightmare in trying to decide on the best channels to use for specific multiplexes on various transmitters when considering co-channel interference, taking account of the obvious line-of-sight issues but also less common propagation due to temperature inversion and tropospheric ducting.
Whilst most of it is done by well established computer predictions, no doubt there'll have to have been some manual fine tweaking ....... and there are some instances were it is far from ideal which is of course why it wasn't done at the outset if that's what you meant by tight groups.
If you meant use of adjacent channels at a given transmitter, that's not a problem with digital, but analogue had to be spaced apart often 3 or 4 channels.
You would have struggled a bit with the Sudbury COM muxes at DSO as these were technically above Group B, a Group E aerial really being needed. And with the 700MHz Clearance those COMs moved right down the band where then a Group K was required.
It was because it was known that these types of changes were likely to be needed in the future that back in the day a Wideband aerial was recommended, or a Group T when the 800MHz band was cleared, and now after 700MHz Clearance, as there's nothing above C48, a Group K is in effect the new wideband and in fact desirable to minimise the likelihood of mobile interference if you could be near a mobile mast using 700MHz.

I can only assume because of the additional complex frequency planning that would have been needed.
At DSO (already an expensive business) the new high power multiplexes in most cases just replaced the analogue transmissions on their allocated channels and no additional (or adjusted) frequency planning was needed.
I'd also guess that since DSO the additional data and experience with digital propagation would have helped tweak the computer models used for such planning.

Thanks. Whatever the reason, the new arrangement is far better than when we had muxes on c58 and c60.
Do you know about aerials? I am staggered how good the log periodic is. Perhaps they have been improved over the years. Does each element receive the signal, thus adding to performance? For example, the longest and shortest element also increase the signal for c39, albeit they are the wrong length?
