Debate about the future of shortwave broadcasting focuses on the correct observation that shortwave listening is no longer a mainstream activity in most of the world.
Radio is the ultimate internet circumvention tool because it is not the internet. And it can’t be tracked.
Amount of energy absorbed by a passive (most common) antenna is negligible. Speakers have human hearing frequency range on them which is 20Hz to 20KHz, this is very low frequency for a radio transmission and hardly goes any distance. Speakers transmiting/receiving any radio waves is considered power loss or interference and is avoided.
There’s no practical method of tracking radio receivers that i know of save for bugging the very receivers.
Tracking transmitters on the other side is fairy simple and anyone can do it with a bit of effort.
Bigger problem is jamming which is emitting noise on same frequency the transmission is on.
Anyone who is capable of transmitting is also capable of jamming, famous examples of it are eastern bloc countries jamming Radio Free Europe and China jamming US propaganda stations.
