For reception problems encountered by relations at NN1 5BT, I took notes of which channels ran OK, which pixellated/dropped out and which didn't load on re-tune at all.
I put that info into a spreadsheet, and pasted in Briantist's info on which MUX each channel was transmitted in, the frequency (MHz) and power (W).
I'd recommend anyone do that.
In the case of NN1 5BT, when I reordered by wattage, they received everything transmitted at 180,000 W on PSB1/2/3 but everything at lower power had problems.
However COM5 is not that much lower in wattage at 170,000 W.
When I reordered by MHz it became clear there were issues with COM5 on 722.0 MHz suggesting a 4G 800 MHz problem.
Solution: low signal strength, probable 4G interference, masthead booster with 4G filter required.
