o(∩_∩)o Hello~ My name is Doraemon Yu, and I am a HAM Radio Operator. Nice to see you here~

Well, where I live and where I usually use signal transmission, is located in the Guangdong Province of Chinese mainland in the Asian Plate of the Big Blue Star.[OL63] (The Big Blue Star here refers to: Laniakea Supercluster -> Virgo Galaxy Cluster -> Milky Way -> Orion Arm -> Gould Belt -> Oort Cloud -> The third planet of the solar system. It has not been verified yet, but if the location is wrong, it may be received by other aliens. XD)

The radio license and operation certificate that I have obtained now, allow me to legally carry out relevant activities in all the amateur wireless radio bands.

Recently, the frequency that I use more often is 439.680 | 439.460 .The time is usually around 12:30 UTC.

I look forward to meeting you again in the atmosphere radio waves. 73!
