Off-Grid Ham Radio OH8STN:

This YouTube Channel contains a wealth of useful information!

— Numerous videos are ordered in categories (and much more):
• Portable Ham Radio Reviews
• Portable Ham Radio Go Kits
• Ham Radio for Preppers
• Microsoft Surface for Ham Radio
• Ham Radio with a Raspberry Pi
• Battery & Solar Power for Ham Radio

Some of these videos have been linked to as comments in various topics here.

I thought it would be nice to have them at your fingertips.
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:

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.
