Thanks guys/gals, the place is indeed NEDUL, and I was indeed refering to the case when it's so busy it's hard to get a word in edgeways, when you guys are maxed out.
Nearly happened yesterday which is why I asked, 5MB thanks, in that case would one solution be to transfer ourselves to solent and explain the situation, (only once in their airspace) so maybe they could speak to you/your assistant on the phone, thus avoiding any probs in their airspace? Or is that a definite no-no?
The skipper I was with reckoned to continue on heading (correct) and sqwark 7600 as we've had a comms failure of sorts! I'm personally not sure of the 76 bit though!
