We live in Dolybont and receive our signal from the Dolybont Freeview transmitter. This morning we lost all signals except those on PSB1 BBCA, namely non-HD BBC1, BBC2 BBC Four, etc. Retuning found a signal at only that one frequency, it did not find the other two channels (PSB2 D3+4, PSB3 BBCB0 we have been using to receive HD broadcasts etc.
I think you have a fault at the Dolybont transmitter that started today, 14/02/2019.

Hi DAB radio signal is very weak or does not work at all within the village of Dol y bont. I have tried different DAB recovers and all struggle to get a signal.
Is this an issue with the transmitter

Liam Williams:
I'm afraid it's simply because the coverage in the area is fairly poor, with the BBC National multiplex the only one you may get and then maybe not a good signal. You are unlikely to get a reliable service.

Liam Williams: Looking at the map of transmitters, I think Blaenplwyf is really the only DAB transmitter you might possibly receive, at just over 8 miles out. The problem is that you are in a valley and it doesn't run in the direction of the transmitter, hence the terrain is casting a shadow.
Blaenplwyf transmits two of the national multiplexes, the BBC National being far more likely to be able to be received than the D1 National, this because the antenna transmitting the BBC multiplex is higher up the mast and the strength of the signal coming in your direction is much stronger.
Here are the details of the Blaenplwyf DAB transmissions. For each multiplex I have given the channel number, the height of the transmitting antenna above ground, the effective radiated power of transmitter, the number of dBs down in your direction and, in brackets, the effective radiated power in your direction:
BBC National: 12B 125m 4.67kW -2.0dB (2.94kW)
D1 National: 11D 83m 1.4kW -2.7dB (0.752kW)
From these figures, what is really of interest are the facts that the BBC antenna is higher up. As the terrain is anything but flat, it casts shadows. The shadows will be larger the lower down the antenna is. The other thing to note is the that the D1 National antenna is throwing out a much less powerful signal in your direction than the BBC one. If you're struggling to get the BBC then you aren't likely to get the D1 multiplex.
The transmitter isn't omnidirectional, meaning the full signal power isn't being thrown out around all 360 degrees. The dB figure is the amount it is down on the full signal power on a bearing of 20degrees out from the transmitter (in the direction Dol-y-Bont), hence I used this to calculate the power in the direction of Dol-y-Bont (shown in brackets).
There is a BBC National transmitter at Machynlleth, but this is blocked by very high ground and too weak in your direction to be of any use.
The next two DAB transmitters distance-wise and that are of any significant power are Arfon (39 miles) and Presely (45 miles). I mention them not because I think you might be able to receive them, because these are the "next best", hence why I say I think that your only possibility, if any, is Blaenplwyf.
Thus, your most likely chance of reception is in the direction of the Blaenplwyf transmitter. And if you're struggling to get the BBC National on 12B, you aren't likely to get the D1 National on 11D.
