I just looked at the video posted previously and have to say that I am not surprised.
Not long ago we were in the cruise over Spain and we could not get a response on the assigned frequency where we had previously established comms.
Thinking we had missed a call, gone out of range or had a comms failure, I asked my colleague to continue making calls while I called on 121.5.
Imagine my surprise when in the background of the "Station Calling Station Calling" I could hear my colleague calling.
5 seconds later all was normal and they could suddenly hear us again - Station Calling !!
perhaps there was a bun fight going on like the one on the video.
