I don't like it when someone tries to ban what's left. Ukraine has already passed many laws that have been asked to be adopted by the EU, which have restricted citizens. I'm not saying that I'm allowed to broadcast in the FM band. Ukraine has a permitted band of 27 MHz. It can use any modulation. Power should be no more than 10 watts. Each transmitter at 27 MHz, outputs harmonics at 56 MHz, 81 MHz, 112 MHz. You can broadcast without a license. Therefore, I can assemble a 27 MHz transmitter without a high pass filter, but it will broadcast at the specified frequencies. I came across things that are allowed in Ukraine, which give a signal on these and other frequencies. For example, a Chinese charger can turn off all FM radios at once. (5 Watts, 20 meters).
I have already assembled such 1 W transmitters. They work no further than 20-100 meters. This transmitter will operate at 400 meters - 2 km
