I will never understand why ANYONE would misuse the 121,5 for anything except a legitimate emergency/PAN! Can't you just arrange with your home airfield or ask for another frequency to use for practice purposes?
In Germany there's a board/board frequency, 122,800, for chatting...122,25 for balloonists, 123,15 for glider training, and so on....
I remember the Pprune discussion here about the 123,45 usage.... shame, shame...
Frequency's are designated for particular purposes, airfields, people, companies, etc.... don't use them for anything else!
There shouldn't even be a need for a discussion about this!
I guess you can tell this is a pet peeve of mine
