BI4OAE Thank you for sharing. I successfully obtained the license, which took about half a day. It was very efficient! I commend the Shandong Industry and Information Technology Bureau. Regarding the commitment letter, I stated that it was less than 15W, and I hope it can help more HAMs. Last year, before applying for the large license from the Ministry of Industry and Information Technology, I called the local radio office and they clearly informed me that machines with a capacity of 100W cannot be used to obtain small licenses.
