QTHR = Registered address.
De = From
Hi Hi. In CW this sounds like a laugh & is used in the same way that LOL is used in written text..To donate it was a joke/not serious.
QAU = Auronatutical Q code, For permission to, or I am going to..Dump fuel..Can be used RAFARS members for the obvious reason..
161 = 73 & 88...

Also please no 73's or best 73's..73 means best wishes, so 73's means best wishes's & Best 73's means best best wishes's...
