I have a discriminator tap wired to my 20 year old Pro 2042. I can still listen into these through my laptop despite them going DMR.
Irvine Shopwatch 453.2375
Rivergate Security 453.3375
WH Malcolms within Ardagh Glass 460.225 (same as what it was on FM)
GSK 456.0125
Ardagh Glass 460.325 (a bit garbled, but at least partially intelligible)
I haven't found anything outwith Irvine yet. I'm not sure if distance is a factor with DMR compared to NFM.
