Are you sure it is a Xeigu?
Is it not an RS-928?

The least of your worries is the soldering, they had different finals depending on where and when they were made, they very rarely gave 10-15W on the higher frequencies, the data given on online sources is mostly wrong on the setup (which is often the result of the finals blowing), and the dis-assembly and re-assembly of some of them is enough to challenge any ones patience. (many are simpler, but again it depends on where and when they were assembled)
They are copies of copies
