No CAP+ nor RAS
But I suspect their "customer service" radios which I know are hyteras running on a simplex channel dont appear to decode suggesting they are
using the new standards "two slot simplex" which DSD / DSD+ (afaik) dont support yet.
As for whether you'd get these in Cardiff depends upon where in cardiff you are.
Take a look at the attached map:
The red "ridge lines" lines I've overlaid roughly show how Newport city centre is isolated to the west and north by two hill ridges (brynglas
ridge omitted for clarity)
The horseshoe shaped ridge that runs from St Wollos , across Stelvio park to the Gaer, up to Glaslwch, the Ridgeway, across to
Alt-yr-yn and Barrack Hill where it is broken by the Usk valley,
On the east side of the river there is a second ridge that goes from Summerhill, across Beechwood and Christchurch and continues
up to the celtic manor.
In part these hills are why Newport city centre has retained much of its historic / victorian architecture as it was very tricky to bomb
the docks and still pull up in time during WWII
The TX sites in question are roughly in the centre of the horseshoe.
As such , if your somewhere like a coastal high spot near St mellons, theres a fair chance
If you're inland a bit, say , Roath or Llanishen, then your probably quite shielded unless you live up on the ridge between Llanedryn and Roath.
I'm fortunate as from my back garden, the next landfall to the west is the wenvoe ridge ! so I have the best of both worlds :-)
