Strange Transmissions

Out yesterday, and received some very strange VHF messages, in French, from France! I even got DSC alerts
Talking to a colleague who is into such things, he says that it is a phenomenon called VHF lift, analagous to diffraction in the atmosphere, brought about by the current high pressure we are experiencing.
Later in the day I was anchored and heard a mayday, which should really have been a pan pan; looked up and it was from a yacht not 50 metres away! Seems a member of the crew had been injured.
Two extremes, isn't technology wonderful
What is the greatest extreme range VHF transmission that you have received?

Oh lord! Why did you unleash that can of worms! Someone will be along to point out its the skippers job to determine if life is in grave or imminent danger...

Did you offer assistance?

My normal cruising ground is the Solent, and that is where I was yesterday.
According to the skipper she had lost a finger, very, very nasty, but I still do not think it should have been a mayday.
And yes, I did offer assistance, but they wished to use the services of the orange RIB.

Extreme Range VHF for me, has been the Space Station, when there was a radio Ham as a crew memeber.. As a Ham I "Booked" a slot and had a 8 Minute conversation.

Wow Brian, that is what I call comms
Back down to earth What I was impressed with was the clarity of the French comms, they came through as clear as Solent CG.
What I was trying to see was if anyone in UK waters has received signals from other areas of mainland Europe; Spain, Portugal, Italy maybe?

slightly different but remember years ago being told about lifeboat station somewhere that had a new radio set installed,
radio engineer set it all up & was working fine next day bad signal ,
transpired that the height of the tide was causing a reflection of the radio waves when the tide was out they had a great signal .

In the days of CB radio when it was AM I used to chat with truckers in the USA - doesn't beat the space station though! Works on a similar principle but involves bounce when the signal bounces of the atmosphere and the sea to reach the USA.

Used to do similar on 144mhz (2m) although we bounced off the Moon !! was really wierd with the delay but had some awesome comms...
