Today I called 127.275 from near the top of Ben Nevis, with my details, saying I would lose them on descent. As I passed 3200', I was given 119.875. I got no reply, and for some time heard only one other aircraft. Crossing from Loch Etive to Loch Awe, I heard them clearly, and passed my details. I thought they were acknowledged. There then followed a long process, being relayed by an unfortunate helpful pilot, of confirming my intentions. At 12.59Z I was over Loch Awe, routing towards Jura, estimating Oban at 14.00Z, having departed Inverness. I feel I caused a lot of bother, and would have been better, in that area, leaving the radio until approaching Oban. Brakes on time was 14.03Z, so my estimate was reasonably accurate.
I later worked 127.275 from Glenforsa to Lochinver, before returning to Inverness.
