Com 7 & 8 have gone completely IP27 0EE, on C55 & C56 = they were fine on C32 & C34 before the change, which I thought was to remove channels on C50 - 59, not put more on them ?????
A Temporary move perhaps?

Mark: Sandy Heath Now has COM7/8 on low power and same frequencies as Oxford the adjacent TX. You may need a very directional aerial (LogPeriodic) to reject signals from Oxford or other sites. In Milton Keynes which is equidistant from Oxford and Sandy some people have lost 15 SD and 9 HD channels. Note also these SFN muxes are HD only so SD channels carried on these Muxes can only be received on a HD tuner TV. The LCNs affected are 55, 56, 67, 82, 84, 87, 97, 98, , 86, 88, 92, 93, 94, 95, 96, 106, 107, 108, 109, 110, 111, 112, 113, 205. Unprofessional planning but they are driving people to Satellite services.

Thanks Colin,
I gathered as much from the loss of signal strength and the wattage comparisons of each mux in the info higher up this page. Despite this all the Com 7 & 8 channels are ok and not dropping out currently. Is it your understanding that they will boost the signal later or is that it? Shocking that people are losing channels because of this.

I lost BBC4 HD, but that came back after the retune. Now I've lost everything on Com7. I can't get BBC News HD. No signal on channel 32 at TVall.

I've had difficulty matching the "How will the Sandy Heath (Central Bedfordshire, England) transmission frequencies change over time?" '30th June 2018' table entry above with the reality.
Here in Sharnbrook, there's been changes, but I'm finding that the table above is about half wrong. What I find is:
- BBCB is currently on C21, not C27 as listed. Whereas BBCA is on C27 not C21 (they didn't swap over during the shutdown).
- D3+4 is right, it is on C24
- SDN doesn't appear to be on C33 at all, I receive it on C51
- COM7 seems to be on C55, but I'm getting massive drop outs, I haven't managed to find COM8.
- ARQA is right, it is on C36
- ARQB is right, it is on C48
Does this match anyone else's experience?
I did wonder if my aerial was picking up a completely different transmitter or something, but it shutdown like clockwork during yesterday's maintenance window, so presumably it IS the Sandy Heath transmitter. I created the list because I've been battling some weird reception problems here (don't ask!), no criticism of anyone is implied. Hope this helps someone.
