Quote from: gil on April 23, 2023, 11:26:59 PMYep, there was also the case of the ship Bounty, reproduction of the original, that sailed in a hurricane off the coast of Florida years ago. Their satellite comms failed in the storm but they were able to send an email to the coast guard via Winlink! If I remember well the captain did not make it but around 14 crew were saved (can't remember this second).

Thank you Gil, most interesting! I never heard about this. Here are more details:

For those who thought HF and MF can be scrapped and replaced entirely by satellite, you can read here what happened when one of the major providers of satellite service was hacked the day Russia attacked Ukraine in February 2022:

Google Translate will do a decent job here if you don't read Norwegian.

A couple of background links about the break of communications:

I want to suggest a new board:

I have lots of links to put in there if my wish is granted.

For listening training, I am adding another semiautomatic bug transmission:


That's not a Vibroplex though, it's this one:

Morse Code / Re: First Time Using a Vibroplex Bug.

Nice! Did you continue using the Vibroplex semiautomatic bug?

I recently discovered this short video with the same kind of Vibroplex that I acquired in a USEC port in 1965, when I was a sailing radio operator. I estimate the speed here to be above 30 WPM, and it equals the speed I mastered at the time. I still own that Vibroplex, and the video inspired me to practice more so I can reach that speed again.

What I really would like to have is a wristwatch similar to the one you see in the video. It was for sale by a British company for about $200. Unfortunately, they were sold out by the time I had saved enogh to buy one.
