There are quite a few, with three and a half active groups in Shenzhen, as well as some new, independent HAM groups.
Every Friday, the Wutongshan branch of the network operates from approximately 2 hours onwards.
I usually contact on several popular repeaters, and I generally get a response every time. In addition, some operators have been consistently monitoring the frequencies.
The quality of the Wutong Mountain repeater is also very good, with a wide coverage range. Many HAM friends from surrounding cities often use it, and last week, a gentleman from Haikou used a simulated signal to contact us on frequency 59, which immediately connected several listening stations for QSL card exchange.
Regarding the local HAM community around Shenzhen, they are generally very active and enthusiastic, and discussions about technical topics are also quite lively.It won't end up like many groups within certain communities, which eventually become echo chambers.。
There are few people participating in online forums within the community, possibly because everyone is busy and doesn't have time to participate. They start up their computers, chat on the forum for a while, and then rest.Furthermore, the hobby of radio communication is quite niche and doesn't have a large enough population base.
