Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Pretty stupid when you are literally broadcasting a radio direction finder beacon directly from your home out to the entire world.

...broadcast it upwards with a reasonably directional antenna, reflecting off the ionosphere.

...broadcast it from a solar powered relay station which you access via optical link from distance.

(Not a ham radio operator, but an anarchist, but I can draw a Doppler radar in GnuRadio and have implemented a monopulse tracker... with lots of help from other people who know better. My assessement: it's easy to track powerful signals on an expected frequency, but very hard to track weak signals which do agile frequency hopping with a random key, or hide among other traffic.)

I feel sad for the Belarusian ham radio operators, however. In case of crisis, they would be the people who could help develop something interesting to help others. They were practising their hobby openly and became targets because of that. People who do clandestine business don't exchange contact information openly.

I guess KGB (they still have it) decided that nothing interesting is ever needed in their land. :(

you super stealthy nvis signal might not be noticed by anyone, including intended recipient, but your antenna farm made form 40m long wires certainly will

I operated on 40m with a dipole I strung up in my attic, so this isn't really true. In WW2 radio operators would build their antennas into plaster walls and other parts of buildings. Very easy to hide even long, large antennas
