As it happens, Welshpool to Liverpool was the first flight I ever did to an airfield in class D airspace, as a very very new PPL(A). I wasn't a PPRuNer at the time, was terrified of the whole thing, and took a more experienced pilot with me, asking him just sit there unless I couldn't cope. RT went something like this:
Whirly: Liverpool approach, this is G-XXXX
Liverpool: G-XXXX pass your message
Whirly (consulting kneeboard): G-XXXX is a PA38 inbound to you from Welshpool, presently 5 miles south-east, request joining instructions.
Liverpool passes QFE and all other expected info, then says: "Report Insch (can't spell it)". Whirly repeats it all back like a good little PPL, then turns to more-experienced-pilot in mild panic and says: "Where the hell is Insch?!!!" More-experienced-pilot grins and points out the two towers which are - or were - a commonly used reporting point if approaching from the south. So...bear that one in mind. But all I really needed to do was repeat back the QFE etc, then say something like "Not familiar with the local area; where's Insch?" No crime in not knowing, and they'd either have told me, or given me something more obvious as a reporting point.
It's worth remembering that RT is about COMMUNICATION primarily. If the words you need aren't in CAP 413, ask briefly, in plain English. Another example of doing this:
Whirly and friend are approaching Ireland over the Irish Sea, bound for Waterford, and talking to Shannon:
Shannon: Report XXXX
(Whirly consults chart, but XXXX is definitely not there.)
Whirly: Shannon, sorry but we can't find XXXX on our chart.
Shannon (sounding amused, and as though talking to two mad foreigners): OK, report YYYY. Do you have that on your chart then?
There are human beings on the other end of that radio.
