To correct a point the MF equipped MRCC's in the UK do have full HF capability and some MRCC's use it including Stornoway, Shetland and Aberdeen although I believe Shetland use the MF freqs I am aware Aberdeen have used HF in the past on more than several occasions, and yes the ARCC / MRCC staff may sit warm and cosy in their ops rooms but they do a hell of a lot of work in preparation for the job to be carried out...it doesn't just happen.
