Welshpool Radio is an information service, not an ATC Tower frequency. My recollection is that one should NOT transmit on such frequencies outside 10nm/3000' (preferably 1000') from the site. For someone to call at over 10 times this altitude is, perhaps unsurprisingly, virtually inviting other users to complain!
'Saying hello', whilst well-intended, might well cause rather more important transmissions to be blocked!
So there. Right, WWW, write out a hundred times: "Llanfairpwyllgwyngyllgogerychwndrobwyllllantisiliogogog och is a long way from Welshpool!"
Spelling mistake.....very probably too many vowels, look you!
