Maybe I'm lucky, but I've just done a rescan on my Freeview DVD recorder, connected to a standard Yagi aerial in the loft, and got 66 TV and radio channels, almost as many as off the hi-gain wideband aerial up on the chimney! And I'm using standard coax cable to a CRT portable TV (the cable's only 2 meters long which helps). I don't know what the signal strength is, as the Toshiba doesn't give that info, but it's excellent quality.

I've had mixed results from the 6th July change (obviously nothing major, and it'll likely be sorted on the 20th).

I now have limited signal for MuxC (was fine before) and now have no signal for MuxD (was limited before).

Auto tuning my Freeview box gave me about four versions of the BBC channels, and it seemed to get confused and slow down, but manual tuning has solved that.

To Dale, you're right about the 8k FFT. It's some fearsome maths but in practical terms it means that older freeview kit can't receive the new BBCA mux. I had to buy myself a new card for my PC (I watch all my TV on PCs).

Hang on! You said Mux2! Isn't that supposed to be 2k? Also Mux2 is now the one I can't receive.

John Stone / Dave E: Although Ch50 hasn't changed at DSO1, there has been a change at the adjacent Ch49. At DSO1, Mux A moved to Ch49 at an increased ERP of 14kW.

Prior to DSO1, Mux 1 was on Ch49 at 7kW. Mux D on Ch50 only has an ERP of 1.1kW so I suppose that the increased power on the adjacent channel could be causing the receivers to have difficulty in picking it up. (Ch49 At) (Ch49 At) (Ch49 At)

Jim D : yes, just checked again. Mux 2 seems to have changed to 8K FFT 2 weeks early. I'm guessing that, combined with its very low power, that might account for some people's problems? I can still get the channels (ITV ; C4 ; C5 etc) but the quality has taken a dive (down at about 50%, previously 80-90%)
Current status of all the muxes according to my TV / PVR here in Ipswich :

CH39 (MUX B) : 16QAM 2K Quality 80%
CH44 (BBCA) : 64QAM 8K Quality 100%
CH49 (MUX A) : 64QAM 2K Quality 100%
CH50 (MUX D) : 16QAM 2K Quality 70-80%
CH54 (MUX C) : 16QAM 2K Quality 70-80%
CH56 (MUX 2) : 64QAM 8K Quality 50% or less

Dale: If, as you say, Mux 2 has already adopted the 8k transmission mode but the actual power remains the same, then this would mean that some people will now struggle to receive this Mux as it's effectively similar to a power reduction.

I guess as annoying as that is, at least there's only about a week and half until it's no longer an issue.
