Sorry, but you're lying!
If you've got a licence to broadcast then you must use professional equipment, that meets the
VERY strict requirements of your licence.
You can't set up a broadcast radio station in the UK, it's illegal - and offenders are heavily prosecuted.
I do have some knowledge of how you do go about it - but it's so complicated, and unlikely to succeed, that it's not worth trying.
Even worse, assuming you
DO get permission, and a licence is issued, you then have to bid to gain that licence - and anyone else can bid against you and might get it instead!.
(A friend who is a professional DJ went through the process, and asked me if I would engineer for him - he was never able to convince the authorities of the need for a station in the town/area he was targeting).
