I've never so heard so much crap spoken on 121.5 as in the UK at the moment - I'm not past there often but have heard numerous weekend warriors bleating that they're "unsure of our position" - trollip! Learn to nav or buy a hundred buck GPS. 121.5 is for emergencies - keep it that way.
Regretfully there's so much chatter that I've taken to muting the volume on 21.5 in order not to have it interfere with the control frequency.
