pjwbb luijp That's correct, but having a certification code means that it's officially approved for you to use, but you can't actually use it at higher power levels.
luijp pjwbb So, if I fill out the verification form, I should only be able to enter 25W, but after querying the approval code, it shows 50W and 100W, which means the verification process is essentially just accepting these values.😂
BG6QED You need to understand that the car's speedometer shows a maximum speed of 220 km/h, but you cannot drive faster than the speed limit for that particular road. Amateur radio is primarily for technical research and experimentation; with an amateur license, you can apply for power levels exceeding 25W for communication experiments. For EME (Earth-Moon Earth) communication in the UV band, a minimum of 200W is required.
sgub BG6QED That being said, even if I promise to use a 15W local government-approved transmitter, they still won't allow me to operate a 100W shortwave device.
triint BG8LID Not all shortwave frequencies are UV. Any frequency above 15W requires application to the Ministry of Industry and Information Technology (MIIT). Theoretically, if local authorities approve it, a shortwave radio station capable of transmitting at 100W should apply for the MIIT's "large license." This is likely due to concerns about large-scale transmissions potentially affecting international communications and national sovereignty.
BI3WKD "@BG6QED": The use of "BG6QED" without authorization is illegal; if the law does not prohibit it, then it is free.
BI1ODV When testing equipment with 50W and 100W, you can achieve passing results by adjusting to a lower power setting.

triint BG6QED I think this is very valuable because it's based on a new regulation that hasn't been fully implemented yet, giving us some time to consider.😉
