Ulster 873

The other day while killing time in the car I dx’ed the MW band on the car radio, and heard live house of commons debate on the air at 873khz, I knew it wasn’t five live as I had passed a phone in on 909am and I checked radio 4 and it wasn’t them. The topic was RIR redundancies so I checked 1341khz and identified it as BBC Radio Ulster. this 1Kw transmission was weak to the car park of Lidl in Darndale North County Dublin but listenable. 1341 is listed as Lisnagarvey does anyone know where 873 is from and where does it serve?
On a similar topic I drove from Dublin to Coleraine (via Armagh) and didn’t loose RTE Radio 1 on RDS all the way. Now RTE says DAB of RTE Radio is not possible

“We have examined the provision of RTÉ DAB in Northern Ireland, but this is not technically feasible at present. Due to the short range coverage of terrestrial VHF transmissions, together with regulatory considerations, it is unlikely that an RTÉ DAB service will reach mainland Britain for the foreseeable future.”

I think RTE VHF could easy feed the DAB up North. And on DAB, the same RTE page “On 1st Jan 2006, our 80th anniversary, we began a DAB service operating on Multiplex 12 C. The new DAB is available in Dublin and the North East.”

Will we see a rush to buy DAB radio sets? Now all we need is RTE to test DRM on 1278Khz; go own – you know you want 2
