7366 and the Manchester LLR
On a trip yesterday to Halfpenny Green from Barton I used the 7366 squawk in the LLR as requested by MAN ATC and was on listening watch only. On both transits I was called by them to advise me of conflicting traffic and a possible obstacle ahead. I was naturally very grateful for the shout but the question is..
After having spoken to ATC at their instigation, am I expected to request leaving the frequency as usual,or just silently QSY? I did the former but was aware that ATC were as always very busy and would be interested in the preferred course of action in this situation.
