A neighbor asked, "If I have a K6 radio with the original firmware and haven't made any modifications, what are my options for receiving shortwave?"
This reminds me of a long-standing problem that has been bothering me.
Is it legal to relay amateur radio signals to other segments? If not, are there any relevant regulations? Is there a way to do this legally? Aren't repeaters also used for relaying? Isn't APRS also used for relaying? And what about the various obscure protocols and methods of sending messages via radio waves?
If possible, could the received shortwave signal be forwarded to the UV band? Is it feasible to implement remote control of a shortwave radio station from within the city using UV technology?
Furthermore, if amateur radio encourages people to conduct technical research, does that mean I am engaging in such research within a reasonable and legal scope?
Another question is whether it's feasible to forward shortwave signals. For example, I can't receive shortwave signals from Xinjiang in Guangzhou. Would setting up a shortwave relay device in Wuhan make it possible to achieve the idea of making shortwave signals more widely accessible across the country?
